Question

Um getting an Error haying Error JSON undefined in IE 7 I have included the JSON2 library as follows

<script type="text/javascript" src="/2-0/javascript/flowplayer-3.2.6.min.js"></script>
<script type="text/javascript" src="/2-0/javascript/jquery-impromptu.js"></script>
<script type="text/javascript" src="/2-0/javascript/iscroll.js"></script>

<script type="text/javascript" src="/2-0/javascript/json2.js"></script>

But um still getting the error on this line in IE 7

data_array = JSON.parse(data)

How to fix this issue

Answer 1

The JSON object and related JSON.parse() and JSON.stringify() methods are only available for (reference):

• Firefox 3.5+
• IE 8+
• Opera 10.5+
• Webkit based (Chrome / Safari)

There is no native support for JSON object in legacy browsers like IE7.

You could enable it through including the json2.js created by Douglas here
