How To Read A Json Object In Js

My controller has a method that is returning string representation of a jsonArray as jsonArray.toString() Now following is the ajax method function loadPropertyFile(url) { $.ajax({

Solution 1:

First you need to parse the JSON string into JavaScript object, and then access the required property:

var obj = JSON.parse(json);
console.log(obj[0]["portal.home"]);

In older browsers which do not have native JSON support, you should use something like Crockford's json2.js, which will give you one; please don't use eval() on JSON, as it can lead to pretty bad things all around.

Solution 2:

Use $.parseJSON (or JSON.parse in modern browsers) to convert your string into a Javascript object:

var json = '[{"portal.home":"Home"},{"displaytag.tracking.id":"Item ID"},{"displaytag.tracking.itemName":"Item Name"},{"displaytag.tracking.itemType":"Type"}]';
var object = $.parseJSON(json);

In your case your JSON string will create an array, so you will need to get the object at the correct index:

var portalHomeValue = object[0]["portal.home"];

Solution 3:

In case you have the JSON directly in your javascript source (which I don't assume, but I'm adding this for others), you can just remove the quotes, and javascript creates an object based on it:

var obj = [{"portal.home":"Home"},{"displaytag.tracking.id":"Item ID"},{"displaytag.tracking.itemName":"Item Name"},{"displaytag.tracking.itemType":"Type"}];
console.log(obj[0]["portal.home"]);

Solution 4:

You can directly access by following

var data =JSON.parse('[{"Item_Number":"M71118LHB","Description":"MENS ONESIE"}]');
var desc = data[0].Description;
console.log(desc);
