checking json value in javascript

Question

var saurabhjson= JSON.stringify(data)

above returns this json

saurabhjson {"recordId":5555,"Key":"5656"}

if print the first array in console it get undefined value

console.log("saurabhjson[0].recordId",saurabhjson[0].recordId);

i want to do some check like this

 if(saurabhjson[0].recordId == 5555) {
            $('#div_ajaxResponse2').text("another success");
        }

why are you converting the JSON to a string? You can access the values from data itself. — Rajaprabhu Aravindasamy

@saurabh remove this line var saurabhjson= JSON.stringify(data) and simply access the values by data.recordId — Rajaprabhu Aravindasamy

@saurabh: There's obviously more going on here than what you're showing us. What is data? Is it a JS object, or a string? Should you be doing JSON.parse() instead of JSON.stringify()? Give us a full example to debug. — Cᴏʀʏ

As the method suggests JSON.stringify(data). It converts a js object to a jsonstring now if you want a key out of this string it can't be done before parsing it to json.

So i don't get it why do you need to stringify it.

And another thing is you have a js object not an array of objects. so you need to use this on data itself:

console.log("data.recordId",data.recordId);

You are probably mixing a few things there.

When you do var saurabhjson= JSON.stringify(data), that saurabhjson variable is a string, not an object, so you can't access its elements like you are trying to do.

Try accessing data directly instead, without using JSON.stringify(): console.log("data.recordId",data.recordId);
