Issue with JSON.stringify adding a extra \ and “” to my Json object

Question

Hi I am creating using Javascript an array of object with a key and a value using the following code.

ValuesArray.push({ key: $(this).attr(\'someattribute\')         


        

Answer 1

May be you have an old prototype library. As I remove it, bug has disappeared

Answer 2

const config = {a: 1, b: 2}
console.log(JSON.stringify(JSON.stringify(config)))

"{\"a\": 1, \"b\": 2}"

Answer 3

It looks like you are placing a string as the value in your map. You should do something like:

var objMap = {"JObject" : ValuesArray}; var json = JSON.stringify(objMap)

What's happening is you are double json encoding your values array - note that your "invalid" JSON value is actually a JSON string rather than the array that you want.

EDIT It looks like you are sticking in JSON strings of maps into an Array and then stringifying that. Here's a jsfiddle that should help you get what you are looking for - http://jsfiddle.net/4G5nF/

In your post request, try this

var jObject = {"JObject" : ValuesArray};
$.ajax({   url: address,
           type: 'POST',
           dataType: 'json',
           data: jObject,
           success: function (data)  { .. }});

Note the change in the data attribute. That is a value that is automatically JSONified for you.
