After receiving a valid JSON string (JSONP) from my server, I needed to parse it on the client side.
Here is an example: parseJSON({ "NAME": "Tom" });
I have implemented this function on the client side:
function parseJSON(myOBJ) {
//myOBJ is already a JSON object but I want to convert it to a JSON string
// so that I can check if the browser supports JSON.parse; otherwise, I will use eval on that string.
}
Although myOBJ is already in JSON object form, I needed it to be converted into a JSON string so that I can verify if the browser supports JSON.parse or else use eval on that string.
If myObj is a JSON Object, then the browser should support JSON (and JSON.parse). To convert back to a string, use JSON.stringify. If you're unsure about the browser's capabilities, consider downloading json2.js from here. It's best to avoid using eval.
[edit]
In your scenario, since it's related to a JSONP request, the object received from such a request is indeed a string. This string gets parsed into a script tag and is subsequently evaluated. All browsers should have no issues with this process; there's no need for client-side JSON handling in this situation.
