How to make function that returns it's inner-function's value?

Question

It's probably obvious to you, but I can't figure it out. I need to make function that returns it's inner-function's value. In other words, I have function get_users() that must return JSON object. That JSON object is got by $.post (built-in jQuery). function get_users() { return $.post( url_base + 'travel/trip/get_users/' + trip_id, function(response) { return response; }, 'json' ); } (above is what I tried to do, but it returned undefined - what a surprise) Because of variable scope, I cannot just make variable in inner-function because it won't be visible in main function. I don't want to use global variables neither. Looking for better solution! Thanks in any advice!

Answer 1

Why are you fighting against the asynchronous nature of AJAX? When you do AJAX you should get accustomed to work with events and callbacks instead of writing sequential code. You can't return the inner contents. The simple reason for this is that this inner function could execute much later than the outer function. So the outer function will return a result much before the success callback executes. So here's the correct way: function get_users() { $.post( url_base + 'travel/trip/get_users/' + trip_id, function(response) { // instead of trying to return anything here // simply do something with the response // Depending on what the server sent you there // will be different ways. // Here you could also call some other custom function // and pass it the response } 'json' ); }
