Founding a values in parsed multidimensional array in javascript

Question

I've got this data serialized by JSON to string:

var json = '[{"data":{"id":2,"gid":3,"name":"Travis","surname":"Stewart","skin":0}},{"data":{"id":3,"gid":3,"name":"Ziutek","surname":"Stewart","skin":0}}]';

And now im going to parse this back to object, like:

var charData = JSON.parse(json);

How can i get data from this for each datas?

for(var char in charData.data) {
console.log(char.id);
}

This wasn't work... Any other solutions?

That console log back me an errors: Error: Cannot read property 'id' of undefined — Mario

at top-level you have an array, so charData.data is wrong. You have to loop over each array item, and access the item data property ; this is not what you've done — Pierre

paste your json into an inline json beautifer, such as jsonviewer.stack.hu, click on "viewer" at the top left, and see your json in a tree representation — Pierre

so you see you have to do something with the array... update your loop to handle that — Pierre

Okay. Got it! Here's the code how can i get this:

var json = '[{"data":{"id":2,"gid":3,"name":"Travis","surname":"Stewart","skin":0}},{"data":{"id":3,"gid":3,"name":"Ziutek","surname":"Stewart","skin":0}}]';
var charData = JSON.parse(json);

for(var char in charData) {
console.log(charData[char].data.name);
}

Thanks a lot for all! :) SOLVED.

you have more then one Data object , so you need to do a forOf To your chardata not to charData.data :

for(var char in charData) {
console.log(charData[char].data.id);
console.log(charData[char].data.name);
 ....
}
