pass JSON string to a javascript function

Question

My server returns a valid JSON string ( JSONP ).

eg parseJSON ( {"NAME":"Tom"} );

on client side i have this function implemented

function parseJSON ( myOBJ ) {

    //myOBJ is already a JSON object but I wanted to it to be a JSON string 
    // so that I can check
    // if browser supports JSON.parse otherwise do eval on that string.
}

myOBJ is already a JSON object but I wanted to it to be a JSON string so that I can check if browser supports JSON.parse otherwise do eval on that string.

If myObj is a JSON Object, the browser supports JSON (and JSON.parse), I would say. If you want to convert back to string, JSON.stringify. If you don't trust the browser, download json2.js. Don't use eval.

[edit]
In your case, seeing it's coming from a a JSONP request, the object such a request returns is a string, and that string is parsed into a script tag, after which it will be evaluated already. All browsers should support that, there's no client side JSON involved here I think.

THanks for your reply. THe problem is I don't know the behavior when JSON.parse is not supported by the browser. How do I write code within parseJSON function to handle this situation. Will myObj be a string still.

Hi kaushal kishore, if the browser doesn't support JSON natively, you'll need an external script to parse it (like json2.js). But see my edits to the answer also.
