I've got a Javascript function called getCartProducts() which gets a JSON array via AJAX using $.post() which returns a value. I want to let my function return that value, but I don't know how to do that.

Here's my function:

function getCartProduct(id){

  $.post('core/ajax/getCartProduct.ajax.php', {id: parseInt(id)}, function(data){

    var result = data;

  });

  return result;

}

I know that this wont work, because te variable result is only active in the $.post() function, but I don't know how to get it straight.

Add a callback function (AJAX is Asynchronous, so your return is being hit before there is any data to return):

function returnData(param) {

    console.log(param);

}

Now add that callback function as a parameter to your AJAX function, and lets run it:

function getCartProduct(id, callback){

    $.post('core/ajax/getCartProduct.ajax.php', {id: parseInt(id)}, function(data){

        callback(data);

    });

}



getCartProduct(id, returnData);
