How to handle my JSON data in jQuery Ajax success callback?

Question

If I have a ajax call:

$.ajax({
  url: url,
  dataType: \'json\',
  data: data,
  success: function(json_data){
    //What\'s the efficient way to extract the JS         


        

Answer 1

A JSON string gets parsed into a JavaScript object/array. So you can access the values like you access any object property, array element:

var name = json_data.contact[0].name;
var addresses = json_data.contact[0].address;

Do access the values inside each address, you can iterate over the array:

for(var i = addresses.length; i--;) {
    var address = addresses[i];
    // address.city
    // address.street
    // etc
}

If you have not so much experience with JavaScript, I suggest to read this guide.
