var string = '[{"title":"Title1"},{"title":"Title2"}]'; var array = JSON.parse(string); array.forEach(function(object) { console.log(object.title); }); Note that JSON.parse isn't available in all browsers; use JSON 3 where necessary.
The same goes for ES5 Array#forEach, of course. This is just an example.
If you're using jQuery, you could use $.each to iterate over the array instead. jQuery has a jQuery.parseJSON method, too.

If you're using jQuery just do:
var myArray = jQuery.parseJSON('[{"title":"Title1"},{"title":"Title2"}]');

If that's directly in your JS then it works out of the box:
var obj = [{"title":"Title1"},{"title":"Title2"}]; alert(obj[0].title); // "Title1"; If it's received via AJAX:
// obj contains the data if( typeof JSON != "undefined") obj = JSON.parse(obj); else obj = eval("("+obj+")"); answered Mar 26, 2012 at 19:02

Using a for loop, perhaps? :o
for(var i = 0; i < jsonVar.length; i++) { alert(jsonVar[i].title); }

Use JSON.parse().
Not all browsers have support for that method, so you can use Douglas Crockford's polyfill. Here: https://github.com/douglascrockford/JSON-js
EDIT: Here's the browser support stats for it: http://www.caniuse.com/#search=JSON

With JSON.parse (json2.js will provide a version of that for older browsers).
Here's an example, using jQuery:
var jsonObj = $.parseJSON('[{"title": "Title1"}, {"title": "Title2"}]'); var title1 = jsonObj[0].title; //Title1 var title2 = jsonObj[1].title; //Title1 You can see a demo here: http://jsfiddle.net/pBb4j/
