How to secure client app (react) and API communication : <p>I have a client side React application and a Rails API from which the React app is fetching data.</p>
<p>As you would expect I only want my React application to be able to fetch data from the API and the rest of the world shouldn't be able to receive data from it. </p>
<p>Despite much searching I am yet to find the best way to secure the communication between the two applications. </p>
<p>I have read about JWT tokens and cookie based session authentication but the majority of articles seem to be focused on authentication of users (ie sign in/sign out) rather than communication between just the two applications. </p>
<p>The two apps will share the same domain so is it enough to rely on Cross Origin to secure communication?</p>
<p>Any advice really would be much appreciated. </p>

How do you adjust the height and borderRadius of a BottomSheet in Flutter? : <p>I'm probably missing something obvious here, but my BottomSheet only takes up the bottom half the screen, even though the widgets in it take up more space. So now there is scrolling behavior inside the BottomSheet. I'd like to be able to increase the BottomSheet so that the user doesn't have to scroll as much.</p>
<p>I also want to add a borderRadius to the top of my BottomSheet, so that it looks more "modal"-y or "tab"-like.</p>
<p>Code:</p>
<pre><code>void _showBottomSheet(BuildContext context) {
showModalBottomSheet<Null>(
context: context,
builder: (BuildContext context) {
return _bottomSheetScreen; // defined earlier on
},
);
}
</code></pre>
<p>I've tried:</p>
<pre><code>showModalBottomSheet<Null>(
context: context,
builder: (BuildContext context) {
return Container(
decoration: BoxDecoration(
borderRadius: _borderRadius,
),
height: 1000.0,
child: _bottomSheetScreen,
);
},
);
</code></pre>
<p>but it seems like that only affects the contents inside the BottomSheet, and does not customize the BottomSheet itself.</p>

how to run python query directly from teamcity : I 2 machines on which I need to download Anaconda.sh and some compiler zipped files. One machine is Linux and I downloaded all zip files plus .sh files using below curl command :-
curl -s -o cmake-3.4.1-Linux-x86_64.tar.gz http://ccm-
XYZ/tools/cmake-3.4.1-Linux-x86_64.tar.gz
As this is the linux machine, I am calling it from teamcity and its working fine as expected. Unfortunately, getting issue with the Windows machine as usually we get error on windows.
I want the same behaviour for windows also. I want to download .gz file as mentioned above from the teamcity build step. And then need to extract it. As of now, I am using python script as below :-
import subprocess
subprocess.call("curl -s -o cmake-3.4.1-Linux-x86_64.tar.gz
http://tools/cmake-3.4.1-Linux-x86_64.tar.gz", shell=True)
It is not running. I think here, the issue is with the running of python commands. Any suggestions here. How can I do that, how can I get into python interactive mode to run the python scripts ??
Thanks in advance.....!! | 0debug |

argparse: flatten the result of action='append' : <p>I'd like to make a script that supports an argument list of the form</p>
<pre><code>./myscript --env ONE=1,TWO=2 --env THREE=3
</code></pre>
<p>Here's my attempt:</p>
<pre><code>import argparse
parser = argparse.ArgumentParser()
parser.add_argument(
'--env',
type=lambda s: s.split(','),
action='append',
)
options = parser.parse_args()
print options.env
$ ./myscript --env ONE=1,TWO=2 --env THREE=3
[['ONE=1', 'TWO=2'], ['THREE=3']]
</code></pre>
<p>Sure I can fix this in postprocessing:</p>
<pre><code>options.env = [x for y in options.env for x in y]
</code></pre>
<p>but I'm wondering if there's some way to get the flattened list directly from argparse, so that I don't have to maintain a list of "things I need to flatten afterwards" in my head as I'm adding new options to the program.</p>
<p>The same question applies if I were to use <code>nargs='*'</code> instead of <code>type=lambda...</code>.</p>
<pre><code>import argparse
parser = argparse.ArgumentParser()
parser.add_argument(
'--env',
nargs='+',
action='append',
)
options = parser.parse_args()
print options.env
$ ./myscript --env ONE=1 TWO=2 --env THREE=3

Disable gesture to pull down form/page sheet modal presentation : <p>In iOS 13 modal presentations using the form and page sheet style can be dismissed with a pan down gesture. This is problematic in one of my form sheets because the user draws into this box which interferes with the gesture. It pulls the screen down instead of drawing a vertical line.</p>
<p>How can you disable the vertical swipe to dismiss gesture in a modal view controller presented as a sheet?</p>
<p>Setting <code>isModalInPresentation = true</code> still allows the sheet to be pulled down, it just won't dismiss.</p>

overwrite hive partitions using spark : <p>I am working with AWS and I have workflows that use Spark and Hive. My data is partitioned by the date, so everyday I have a new partition in my S3 storage.
My problem is when one day the load data fails and I have to re-execute that partition. The code that writes is next:</p>
<pre><code>df // My data in a Dataframe
.write
.format(getFormat(target)) // csv by default, but could be parquet, ORC...
.mode(getSaveMode("overwrite")) // Append by default, but in future it should be Overwrite
.partitionBy(partitionName) // Column of the partition, the date
.options(target.options) // header, separator...
.option("path", target.path) // the path where it will be storage
.saveAsTable(target.tableName) // the table name
</code></pre>
<p>What happens in my flow? If I use the SaveMode.Overwrite, the complete table will be delete and I will have only the partition saved. If I use the SaveMode.Append I could have duplicate data. </p>
<p>Making a search, I found that Hive support this kind of overwrite, only partition, but using the hql sentences, I don´t have it.</p>
<p>We need the solution on Hive, so we can´t use this <a href="https://stackoverflow.com/questions/38487667/overwrite-specific-partitions-in-spark-dataframe-write-method">alternative option</a> (direct to csv).</p>
<p>I had found this <a href="https://issues.apache.org/jira/browse/SPARK-20236" rel="noreferrer">Jira ticket</a> that suppose to solve the problem that I´m having, but trying that with the last version of Spark (2.3.0), the situation was the same. It delete the whole table and save the partition instead of overwrite the partition that my data has.</p>
<p>Trying to make clearer this, this is an example:</p>
<p>Partitioned by A</p>
<p>Data: </p>
<pre><code>| A | B | C |
|---|---|---|
| b | 1 | 2 |
| c | 1 | 2 |
</code></pre>
<p>Table:</p>
<pre><code>| A | B | C |
|---|---|---|
| a | 1 | 2 |
| b | 5 | 2 |
</code></pre>
<p>What I want is: In Table, the partition <code>a</code> stay in table, partition <code>b</code> overwrite with the Data, and add the partition <code>c</code>. Is there any solution using Spark that I can do this? </p>
<p>My last option to do this is first deleting the partition that is going to be saved and then use the SaveMode.Append, but I would try this in case no other solution.</p>

Wil a C/C++ compiler inline a for-loop with a small number of terms? : Suppose I have a class `5x5matrix` (with suitably overloaded index operators) and I write a method `trace` for calculating the sum of its diagonal elements:
double 5x5matrix::trace(void){
double t(0.0);
for(int i(0); i <= 4; ++i){
t += (*this)[i][i];
}
return t;
}
Of course, if I instead wrote:
return (*this)[0][0]+(*this)[1][1]+(*this)[2][2]+(*this)[3][3]+(*this)[4][4];
then I would be sure to avoid the overhead of declaring and incrementing my `i` variable. But it feels quite stupid to write out all those terms!
Since my loop has a "constexpr" number of terms that happens to be quite small, would a compiler inline it for me? | 0debug |

How to Pass Parameter to array.map()? : <p>I am trying to map values to a function that will accept two numbers to multiply but am having trouble doing so (if this doesn't make sense, take a look at the examples below).</p>
<p>I have an array of numbers and I would like to double/triple/quadruple... the values of this array. I have created functions that would do this, and am feeding these <code>double()</code> and <code>triple()</code> into <code>map()</code>.</p>
<pre><code>var arr = [1, 2, 3, 4, 5];
function double(num) {
return num * 2;
}
function triple(num) {
return num * 3;
}
console.log( arr.map(double) );
console.log( arr.map(triple) );
</code></pre>
<p>This solution is not scalable as what if I want to multiply the values by 5, or 10? I need a more abstract function that would take a parameter of what to multiply. I am confused about how to do this. My attempt so far is:</p>
<pre><code>var arr = [1, 2, 3, 4, 5];
function multiply(num, multiplyBy) {
return num * multiplyBy;
}
console.log( arr.map(multiplyBy(4) ); // Uncaught TypeError: NaN is not a function
</code></pre>
<p>How would I pass <code>multiply()</code> the <code>multiplyBy</code> parameter?</p>

A namespace-style import cannot be called or constructed, and will cause a failure at runtime : <p>Strange stuff happening here, with TypeScript 2.7.2, in VSCode version 1.21 with @types/express and the code that follows, in some cases VSCode throws errors stating that "A namespace-style import cannot be called or constructed, and will cause a failure at runtime.". However on other machines with similar setups and similar tsconfig.json files the code just works.. What is happening here:</p>
<pre><code>import { Bank } from './Bank';
import * as Express from 'express'; <== errors here..
let app: Express.Express;
this.app = Express(); <== and here
</code></pre>

Implementing HashMap: Avoid collisions caused by compress function : <p>I'm implementing a hashmap to contain all words in a word file (e.g <code>dictionary.txt</code>, <code>bible.txt</code>) and I am having a collision problem. I know that there are many good hash functions out there but when I try compressing the hash code using this compression function, the number of collisions raises significantly (I'm using <a href="http://www.cse.yorku.ca/~oz/hash.html" rel="nofollow noreferrer" title="dbj2">dbj2</a> for my hash function).</p>
<p>My hashmap basically converts a key to its hash value and compresses that hash value to the index of the entry in the internal hash table, which is an array. It resizes itself to <code>2 * capacity - 1</code> if the <code>load factor</code> of <code>0.5</code> is reached. When collisions happen, my hashmap generates new indexes using quadratic probing.</p>
<p>This is what my current compress function looks like:</p>
<pre><code>private int compress(int hashCode) {
return Math.abs(hashCode) % capacity;
}
</code></pre>
<p>Is there any (efficient) way I can do to avoid collisions? Changing the structure of the hashmap itself is also accepted.</p>

Sorting a Tuple list by the Counter Python : Python 3.6+ I have a list of tuples
tuple_list=[(a=3,b=gt,c=434),(a=4,b=lodf,c=We),(a=3,b=gt,c=434)]
I want to count the number of duplicates in the list and then sort the list so the number with the highest duplicates is at the top so I used
tuple_counter = collections.Counter(tuple(sorted(tup)) for tup in tuple_list)
But this returns in error because
TypeError: unorderable types: int() < str()
I've also tried this but it doesn't seem to sort by the highest counter.
tuple_counter = collections.Counter(tuple_list)
tuple_counter = sorted(tuple_counter, key=lambda x: x[1])
As well as this
tuple_counter = collections.Counter(tuple_list)
tuple_counter = tuple_counter.most_common()
Is there a better way to do this?

Changing chunk background color in RMarkdown : <p>I would like to have a certain code chunk highlighted in a different color (e.g. red) to indicate that it is bad practice. If I was using <code>.Rnw</code>, I could add the chunk option <code>background = 'red'</code> and get what I want, but this does not seem to work in <code>.Rmd</code>. My guess is that I need to make a custom css stylesheet (though what the selector would be, I don't know), and maybe also create a custom hook. I'd like it to be on a per-chunk basis, not an overall change for the entire document.</p>

Netty: Idle State Handler is not showing if channel is idle : <p><strong>My Requirement:</strong><br>
I want to detect if the channel is idle for reading for some amount of time and want to timeout based on that. My Netty client is sending request to 1000 servers. </p>
<p><strong>Problem</strong>: My Netty Client is never showing that if there is any idle channel for sometime even if i am using some ips that will always timeout.
I doubt that i am not implementing IdleStateHandler correctly. I have tried decreasing read timeout of IdleStateHandler but no luck. I have spent hours in figuring this out. Any help will be really appreciated.<br>
So, below is my code:<br>
<strong>My Netty Client:</strong></p>
<pre><code>public void connect(final InetAddress remoteAddress){
new Bootstrap()
.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, connectionTimeout)
.option(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT)
.group(eventLoopGroup)
.channel(NioSocketChannel.class)
.handler(httpNettyClientChannelInitializer)
.connect(remoteAddress, serverPort)
.addListener(new ChannelFutureListener() {
@Override
public void operationComplete(ChannelFuture future) {
future.cancel(!future.isSuccess());
}
});
}
</code></pre>
<p><strong>My Netty Channel Initalizer:</strong></p>
<pre><code>public class HttpNettyClientChannelInitializer extends ChannelInitializer<SocketChannel> {
private final Provider<HttpNettyClientChannelHandler> handlerProvider;
private final int timeout;
private int maxContentLength;
@Inject
public HttpNettyClientChannelInitializer(Provider<HttpNettyClientChannelHandler> handlerProvider,
@Named("readResponseTimeout") int timeout, @Named("maxContentLength") int maxContentLength) {
this.handlerProvider = handlerProvider;
this.timeout = timeout;
this.maxContentLength = maxContentLength;
}
@Override
protected void initChannel(SocketChannel socketChannel) {
ChannelPipeline pipelineNettyClientChannel = socketChannel.pipeline();
pipelineNettyClientChannel.addLast("codec", new HttpClientCodec());
pipelineNettyClientChannel.addLast("idleStateHandler", new IdleStateHandler(timeout,0,0, TimeUnit.MILLISECONDS));
pipelineNettyClientChannel.addLast("aggregator", new HttpObjectAggregator(maxContentLength));
//handlerProvider.get() will provide new instance of channel handler
pipelineNettyClientChannel.addLast("handler", handlerProvider.get());
}
}
</code></pre>
<p><strong>My Netty Channel Handler</strong></p>
<pre><code> @ChannelHandler.Sharable
public class HttpNettyClientChannelHandler extends SimpleChannelInboundHandler<HttpObject> {
@Override
public void channelActive(ChannelHandlerContext channelHandlerContext){...}

Multiple headers, how to use function on Object : <p>How do I access a variable or typedef in a header from a method? It seems that the typedef isn't global even though I included the header file, why?</p>
<p>I have the following situation:</p>
<h1>Snake.h</h1>
<pre><code>#ifndef SNAKE_H
#define SNAKE_H
#include <utility>
class Snake {
public:
Snake(int difficulty, int posX, int posY) : difficulty(difficulty) {
position.first = posX;
position.second = posY;
}
inline std::pair<int,int> const getPosition() {
return position;
}
private:
typedef std::pair<int, int> Point;
Point position;
};
#endif // !Snake.h
</code></pre>
<h1>Movement.cpp</h1>
<pre><code>#include "Movement.h"
#include "Snake.h"
Snake moveDown() {
Point dummy = SnakeObject.getPosition();
return .....;
}
</code></pre>
<p>Now obviously this doesn't compile since there is stuff missing, but the compiler fails to recognize the Point type in the Movement.cpp file.
Also, do I need a Snake pointer in the Movement.h so I can use the snake object to call getPosition?</p>
<p>I'm sorry for the vague description, also your help is much appreciated.</p>

How to detect duplicate words in a list and count them in a specific way : <p>I've been learning python 3 for about 1 week now and I just can't find a way to do this, so here is my question.</p>
<p>I have this list:</p>
<pre><code>['apple', 'banana', 'apple', 'tomato', 'carrot', 'apple', 'banana']

<p>Now I want to detect the duplicated words, count them, put the result in front of the word and print in a single string like this example:</p>
<p>Apple 3, Banana 2, tomato, carrot</p>

Node.js, Mongo find and return data : <p>I’m new to node and mongo after 15 years of VB6 and MySql. I’m sure this is not what my final program will use but I need to get a basic understanding of how to call a function in another module and get results back.</p>
<p>I want a module to have a function to open a DB, find in a collection and return the results. I may want to add a couple more functions in that module for other collections too. For now I need it as simple as possible, I can add error handlers, etc later. I been on this for days trying different methods, module.exports={… around the function and with out it, .send, return all with no luck. I understand it’s async so the program may have passed the display point before the data is there.</p>
<p>Here’s what I’ve tried with Mongo running a database of db1 with a collection of col1.</p>
<pre><code>Db1.js
var MongoClient = require('mongodb').MongoClient;
module.exports = {
FindinCol1 : function funk1(req, res) {
MongoClient.connect("mongodb://localhost:27017/db1", function (err,db) {
if (err) {
return console.dir(err);
}
var collection = db.collection('col1');
collection.find().toArray(function (err, items) {
console.log(items);
// res.send(items);
}
);
});
}
};
app.js
a=require('./db1');
b=a.FindinCol1();
console.log(b);
</code></pre>
<p>Console.log(items) works when the 'FindinCol1' calls but not console.log(b)(returns 'undefined') so I'm not getting the return or I'm pasted it by the time is returns. I’ve read dozens of post and watched dozens of videos but I'm still stuck at this point. Any help would be greatly appreciated.</p>

React: The `style` prop expects a mapping from style properties to values, not a string : <p>I have the following HTML to render using React:</p>
<pre><code> <a
style='background-color:black;color:white;text-decoration:none;padding:4px 6px;font-family:-apple-system, BlinkMacSystemFont, "San Francisco", "Helvetica Neue", Helvetica, Ubuntu, Roboto, Noto, "Segoe UI", Arial, sans-serif;font-size:8px;font-weight:bold;line-height:1;display:inline-block;border-radius:3px'
href= //...

rel='noopener noreferrer'

<span style='display:inline-block;padding:2px 3px;font-size:11px'>
<i className='fas fa-camera-retro'></i>
</span>
<span style='display:inline-block;padding:2px 3px'>Photographer name</span>
</a>
</code></pre>
<p>When I try to compile, I get the following warnings about each <code>style</code>:</p>
<pre><code>Style prop value must be an object
</code></pre>
<p>And the error:</p>
<pre><code>The `style` prop expects a mapping from style properties to values, not a string.
</code></pre>
<p>The suggested solution from the compiler, as well as online, states:</p>
<pre><code><div style={{ styleAttribute: 'whatever', ... }}>
</code></pre>
<p>So I've tried the following:</p>
<pre><code> <a
style={{background-color:'black';color:'white';text-decoration:'none';padding:'4px 6px';font-family:'-apple-system , BlinkMacSystemFont, \"San Francisco\", \"Helvetica Neue\", Helvetica, Ubuntu, Roboto, Noto, \"Segoe UI\", Arial, sans-serif ';font-size:'8px';font-weight:'bold';line-height:'1';display:'inline-block';border-radius:'3px'}}
href= //...
target='_blank'
rel='noopener noreferrer'
className='credit-box-abs'
>
<span style='display:inline-block;padding:2px 3px;font-size:11px'>
<i className='fas fa-camera-retro'></i>
</span>
<span style='display:inline-block;padding:2px 3px'>Photographer name</span>
</a>
</code></pre>
<p>But the syntax is not correct. Am I supposed to wrap all values of each attribute in <code>''</code>? In particular, the syntax for <code>background-color: 'black'</code> is giving redlines under, as well as redline under my closing <code></a></code> tag.</p>

Difference in using malloc() vs "operator new" function in C++ : The thread here answers the question about the difference between the two: [diff-between-malloc-operatornew][1]
What I'm interested to know is: does one use the other? I suspect "operator new" function calls malloc in some form, but I may be way off. Anyone knows the implementation with say gcc?

How to start and stop a MS edge browserwindow from a VB script : So I want to start an MS Edge browser and close it after a few moments.
I've tried some things like the Microsoft Internet Controls.
But I need a different browser than the IE.
Dim pi As New Process
pi = Process.Start("shell:Appsfolder\Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge",
Threading.Thread.Sleep(1000)
pi.CloseMainWindow() -- NullReferenceException
But I always get a null reference exception even tho I've initialized it.
Can someone help?
Thanks in advantage

UITextView with hyperlink text : <p>With a non-editable UITextView, I would like to embed text like this in iOS9+:</p>
<blockquote>
<p>Just <a href="http://example.com" rel="noreferrer">click here</a> to register</p>
</blockquote>
<p>I can create a function and manipulate the text but is there a simpler way? </p>
<p>I see that I can use NSTextCheckingTypeLink so getting the text clickable without the 'click here' part is straightforward in Interface Builder:</p>

<p>Just <a href="http://example.com" rel="noreferrer">http://example.com</a> to register</p>

Firebase sign out not working in Swift : <p>I am using newest Firebase API (3.2.1) and I am using this code to check if user is signed in:</p>
<pre><code>override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if(self.navigationController != nil){
self.navigationController!.setNavigationBarHidden(true, animated: true)
}
if(FIRAuth.auth() != nil){
self.performSegueWithIdentifier("loginSuccessSegue", sender: self)
}
}
</code></pre>
<p>In other words if auth object is present I am switching to other controller. On that controller I have sign out button which is doing sign out like this:</p>
<pre><code>do{
try FIRAuth.auth()?.signOut()
self.performSegueWithIdentifier("logoutSegue", sender: self)
}catch{
print("Error while signing out!")
}
</code></pre>
<p>I do not get error on this operation but when I am switched to login controller, this auth object is present and I get switched back again to controller with data. I also tried checking the current user object in auth and it is present and valid.</p>
<p>Anyone knows how an I properly do sign out?</p>

Deserialize a JSON into a list of C# objects : <p>I'm developing a mobile game project that utilizes Firebase. I've managed to get login/registration, and <em>sending</em> items to the database to work just fine. However, after countless hours of banging my head against the wall, I just can't get the inventory to work. I can fetch the correct JSON data from the database, and it comes out in the following format:</p>
<pre><code>{"5449000085757":{"itemLevel":82,"itemName":"Sword of Maximum Epicness","itemType":""},"6419800152996":{"itemLevel":45,"itemName":"Your Average Sword","itemType":""}}
</code></pre>
<p>These are all just fields for testing purposes of course. What I'm trying to do is create a list of objects, where the list is the "inventory" and the objects are the items. I've tried using Json.NET, Unity's built-in JSON utilities, all kinds of technologies, but just can't find a way. I feel kind of stupid, because obviously it can't be this difficult. No matter what example I've tried, it doesn't work.</p>
<p>If possible, could someone provide a quick briefing on how to create that list of objects from JSON, a simple way? I just can't figure this out on my own and it's getting really frustrating.</p>

But, I got an error as follows :
human.SetName undefined (type interface {} is interface with no methods)
seems func SetName doesn't included in SomeMethod func
Why is it? Any answer will be highly appreciated !

how to deallocate memory spaces in Java. ? : <p>I am working on an enhancement project which had an issue, " The process of the android app is slowed proportionally as the usage of app is increased" I figured out the reason for the slow process is accumulation of data in cache memory, which is not cleared after the particular session is closed(i.e the cache memory remains even after the app is closed.). Since the app is developed in Java I couldn't use Destructor to clear the memory space.
Can any one suggest the possible way to deallocate the memory space.?</p>

React testing setup with rails/webpacker : <p>I've added <a href="https://github.com/rails/webpacker" rel="noreferrer">webpacker</a> to my existing rails app, everything is working like a charm.</p>
<p>Webpack config is found under</p>
<pre><code>config/webpack/shared.js
config/webpack/development.js
config/webpack/production.js
</code></pre>
<p>node_modules are installed in</p>
<pre><code>vendor/node_modules
</code></pre>
<p>js pack files are in</p>
<pre><code>app/javascript/packs/application.js
</code></pre>
<p>I've installed react and wrote a little component:</p>
<pre><code>app/javascript/discover/example.jsx
</code></pre>
<p>Now I struggle with how to setup a working test environment. Normally I'd say the usual test setup should include: <code>karma</code>, <code>jasmine</code> or <code>mocha</code>, <code>webpack</code>.</p>
<p>Where should the config files live? Where will the test files be stored and to build a <code>karma.config.js</code> to bundle everything together.</p>
<p>It would be great to have a sample application that shows how to do all that correctly, but I obviously lack the necessary skills to plug everything together correctly.</p>
<p>This is not an easy to answer question, but having such an example application would be extremely helpful to a lot of people that'd want to use webpacker in the future.</p>
<p>Thanks for any thoughts on that topic,<br>
Jo</p>

Add html inside a value to a javascript object : I'm working with a google sheet: my goal is to parse the html and turn into a json file in order to add some places to a google map (api), since in my google sheet I saved some map locations. So far so good, I was able to clean the html file and obtain a json file with all the value I need. My problem is that now, I want to add some html inside the json file. My single value looks like that:
{
"a": "Store Name",
"b": "Address",
"c": "Town/City",
"d": "Prov",
"e": "Postal Code",
"f": "Phone",
"g": "Website",
},
{
"a": "Nutter's Bulk Foods #50",
"b": "102-400 Main Street",
"c": " N.E.",
"d": "Airdrie",
"e": "AB",
"f": "T4B 2N1",
"g": "(403) 948-6354",
},
{
"a": "King Drug Hinton 1982 Ltd.",
"b": "145 Athabasca Avenue",
"c": "Hinton",
"d": "AB",
"e": "T7V 2A4",
"f": "(780) 865-2645",
"g": "http://www.kingdrug.ca/",
},
and so on.
I want to add some html inside the single value in order to change my file into:
{
"a": "King Drug Hinton 1982 Ltd.",
"b": "145 Athabasca Avenue",
"c": "Hinton",
"d": "AB",
"e": "T7V 2A4",
"f": "<a href='tel:+1780..'>(780) 865-2645</a>",
"g": "<a href='http://www.kingdrug.ca/'>http://www.kingdrug.ca/</a>",
}
And I would like to do it dynamically, in order to save time, so let's say that I want to target the property name "a", retrieve the value "780..." and add an html anchor tag <a> with the <href> equal to the value inside the file. The biggest problem for me is working with a json file, I used to word and iterate with javascript object. Thank you in advance for any useful suggestion. | 0debug |
