I tried to parse this string :

[{ZoneId: 1, 0: 1, ZoneX: 29, 1: 29, ZoneY: 27, 2:     27, ZoneWidth: 76, 3: 76, ZoneHeight: 61, 4: 61, ZoneImage: 46, 5: 46, ZonePointTo: 2, 6: 2},

{ZoneId: 2, 0: 2, ZoneX: 382, 1: 382, ZoneY: 226, 2: 226, ZoneWidth: -117, 3: -117, ZoneHeight: 98, 4: 98, ZoneImage: 46, 5: 46, ZonePointTo: 3, 6: 3},

{ZoneId: 3, 0: 3, ZoneX: 108, 1: 108, ZoneY: 74, 2: 74, ZoneWidth: 363, 3: 363, ZoneHeight: 83, 4: 83, ZoneImage: 46, 5: 46, ZonePointTo: 2, 6: 2}]

Using JSON.parse() on this string show me undefined in the console. According to this site, my json is valid. It comes from a json_encode given by a php function.

If it can help, the final goal is to loop through this json array. Thanks.

[EDIT]

I realized that my error was in fact a scope issue using literal functions. Yes, I'm a bit stupid sometimes. Thanks everybody for your help!

This is no String, its a valid JSON which you can use in JavaScript:

var jsonData = [{ZoneId: 1, 0: 1, ZoneX: 29, 1: 29, ZoneY: 27, 2:     27, ZoneWidth: 76, 3: 76, ZoneHeight: 61, 4: 61, ZoneImage: 46, 5: 46, ZonePointTo: 2, 6: 2},

{ZoneId: 2, 0: 2, ZoneX: 382, 1: 382, ZoneY: 226, 2: 226, ZoneWidth: -117, 3: -117, ZoneHeight: 98, 4: 98, ZoneImage: 46, 5: 46, ZonePointTo: 3, 6: 3},

{ZoneId: 3, 0: 3, ZoneX: 108, 1: 108, ZoneY: 74, 2: 74, ZoneWidth: 363, 3: 363, ZoneHeight: 83, 4: 83, ZoneImage: 46, 5: 46, ZonePointTo: 2, 6: 2}];



for(index in jsonData) {

    alert(JSON.stringify(jsonData[index]));

}
