help with JSON

[SirCodesALot]

Hi All,

Is it possible to create an JSON object from a string? For example

var myArray = new Array(10)

for (var i=0;i<10;i++)
{
myArray.push("{idx:"+i+",val:"+i+"}");
}

var myStrObj = "[" + myArray.join(",") + "]";

var options = {"val1": "test",
"val2" : myStrObj}

I would like val2 to be an array of the values from myArray. is this
possible, or do i have to break it out manually?

Thanks in advance for your suggestions.

Hand building JSON is really not a great idea. It is very error
prone.. It is better to build up a JavaScript object and then use a
JSON dumper function

http://www.json.org/json2.js

var options = {val1:"test", val2:[{idx:0, val:0},{idx:1, val:1}]};
JSON.stringify(options);
