Convert JSON string to array of JSON objects in Javascript

Question

I would like to convert this string

{\"id\":1,\"name\":\"Test1\"},{\"id\":2,\"name\":\"Test2\"}

to array of 2 JSON objects. How should I do

Answer 1

I know a lot of people are saying use eval. the eval() js function will call the compiler, and that can offer a series of security risks. It is best to avoid its usage where possible. The parse function offers a more secure alternative.

Answer 2

As Luca indicated, add extra [] to your string and use the code below:

var myObject = eval('(' + myJSONtext + ')');

to test it you can use the snippet below.

var s =" [{'id':1,'name':'Test1'},{'id':2,'name':'Test2'}]";
var myObject = eval('(' + s + ')');
for (i in myObject)
{
   alert(myObject[i]["name"]);
}

hope it helps..

Answer 3

Using jQuery:

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');

jsonObj is your JSON object.

Answer 4

As simple as that.

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
 dataObj = JSON.parse(str);

Answer 5

Append extra an [ and ] to the beginning and end of the string. This will make it an array. Then use eval() or some safe JSON serializer to serialize the string and make it a real JavaScript datatype.

You should use https://github.com/douglascrockford/JSON-js instead of eval(). eval is only if you're doing some quick debugging/testing.

Answer 6

If your using jQuery, it's parseJSON function can be used and is preferable to JavaScript's native eval() function.
