When attempting to evaluate JSON data on a specific computer, the function JSON

Something strange is happening and I can't seem to figure it out, causing a big issue for me.

I am currently working on a .Net web application that utilizes JSON (not json2) along with other JS libraries. In one specific proxy, the function JSON.eval() is used. However, this method seems to be undefined on a tester's computer. Interestingly, on my own computer (connecting to the same servers as hers), I have access to the complete JSON object:

JSON 
{
    copyright : "(c)2005 JSON.org",
    license : ...
    stringify : ...
    eval : ...
    parse : ...
}

On the problematic PC (both running Win7 with IE9), only the following properties are available when evaluating JSON from the debugger console:

JSON 
{
    stringify : ...
    parse : ...
}

It feels like there's something obvious that I'm missing...

Answer №1

It appears that there is an outdated version of a third-party JSON object implementation being included somewhere. The method JSON.eval() is no longer considered standard and has been removed from Crockford's JSON. The recommended methods to use are .stringify() and .parse(), which are part of the browser's native implementation. For more information, refer to: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON

Edit: To resolve this issue, it is suggested to update your code to utilize JSON.parse()
