'JSON' is undefined error in JavaScript in Internet Explorer

Question

We are using jQuery in our application. We have used a jQuery plugin to implement JavaScript session.

It is working properly in Firefox and most Internet Explorer 8

Answer 1

I had this error 2 times. Each time it was solved by changing the ajax type. Either GET to POST or POST to GET.

$.ajax({
        type:'GET', // or 'POST'
        url: "file.cfm?action=get_table&varb=" + varb
    });
