Jquery ajax only want to save 1 value to a variable to use later Javascript

Question

Ok. So I've finally figured out how to get a JSON Get request, but I'm having a hard time figuring out how to use the information I get back. I've got 9 items in the array, but I only care about 1 of the values. I'm trying to get the id: value and store it in a variable to use later. I know I currently have no attempt at doing the storing bit in the code - I've tried so many options, I reverted the code back to where it would at least get the array.

Here is the ajax code:

 var childSection;
        var url = "https://myurl.com";
        $.ajax({
    'async': true,
    'type': "GET",
    'global': false,
    'dataType': 'JSON',
    'data': JSON.stringify(childSection),
    'contentType': "application/json",
    'url': url,
    'success': function (data) {
        childSection = data;
        return childSection;  
    }

Assuming the picture is of the data object, I think childSection = data[0].id should do the trick. — clarmond

Yes, it's just a picture of the array, but I can't upload pics yet :P I'll try your suggestion. — Chad Scott

Inside the "success" property, you have a function which is receiving the data. You can take data and access the node that you want to save. Let's say the node in question is called wutangclan, you can access it like so: data.wutangclan.

If you want to be able to get to data.wutangclan outside of the success function, there are several ways, but basically you want to assign it to a variable that was created outside of the success function.

Also, another way to do this is like so:

// since I defined this in the global scope, I can access it later inside the done function
var myGlobalVariable;

var request = $.ajax({
          url: url,
          method: "GET",
          data: {
              yourdata: the_value_to_send
          },
          dataType: "json"
        });

        request.done(function(data) {
          myGlobalVariable = data.wutangclan
        }
