javascript - jQuery. Assign JSON as a result to a variable

Question

I use this helper function to receive JSON results for my requests:

function getData(url) {
    $.get(url,
         function(data) {
             response = data;
             return response;
         }, 'application/json');
}

I give it some string as a part of url from my web application, like '/api/getusers', so it looks like getData('/api/getusers'). Now I need that string result containing JSON data that I receive from the url to be assigned to my variable, so it would look like this: var result = getData('/api/getusers'). Then I will process this JSON data. The problem is with the returning the response variable. It's undefined. Thanks!

try this

function getData(url) {
var data;
    $.ajax({
        async: false, //thats the trick
        url: 'http://www.example.com',
        dataType: 'json',
        success: function(response){
           data = response;
        }
    });
    return data;
}
