What is the best way to change a string containing single quotes to double quotes in order to JSON parse it

My PHP code involves encoding an array using json_encode.

 $params = array(1=>'something','2'=>'two');

While the encoding process itself works fine, I encountered an issue when trying to embed the JSON data into an anchor tag. The presence of double quotes in the encoded data was causing conflicts with the HTML attributes.

<a class="btn ajax" data-method="test" data-params="{"one":"something","2":"two"}" href="#">test ajax link</a>

The second double quote within the "data-params" attribute was particularly problematic as it disrupted the link functionality.

To address this, I attempted to convert the string from double to single quotes for parsing in JavaScript:

 var string = {'one':'something','2':'two'} ;

However, my attempt to use JSON.parse on this string failed. I tried:

 var jsonString = dataParams.replace('\'', '"');

But this only replaced the first single quote and did not resolve the issue completely. Any suggestions on how to overcome this challenge?

Answer №1

It's a more effective strategy to utilize the htmlentities() function for encoding the " as &quot;, allowing you to include it as data-*. Upon retrieval with JavaScript, they will display as ", enabling immediate use of JSON.parse;

<a data-foo="<?php echo htmlentities(json_encode(array('demo' => 'test'))); ?>">Hey</a>
<script>alert(JSON.parse(document.getElementsByTagName("a")[0].dataset.foo).demo);</script>

Answer №2

Here's an alternative option:

let updatedString = jsonData.replace(/'/g, '"');
