Q:

JSON undefined in IE7

I am using the following line of JQuery code:
$.get('/ajax/buy', {'categoryname':chosenSelected}, function(data) {
   data = JSON.parse(data);
...

However, when running it on IE7 I get this error message: JSON undefined:.
How can I use the parser with compatibility to IE7 (and all major browsers)?

A:

You can use parseJSON available in jQuery.

A:

You don't need to parse JSON manually. You could use the getJSON function:
$.getJSON('/ajax/buy', { 'categoryname' : chosenSelected }, function(data) {

    // data will be already a parsed JSON object
});

The parse method you are trying to call is available in the json2 library.
