Promote callback onSuccess return value to the Caller Function return value

Question

I have a javascript function that calls a generic function to make an ajax call to the server. I need to retrieve a result (true/false) from the callback function of the aja

Answer 1

Just found how to do it :) Declaring a variable and updating it accordingly from the callback function. Afterwards I can return that variable. I place the code for future readers:

function CallServer(urlController) {
    var returnValue = false;
    $.ajax({
        type: "POST",
        url: urlController,
        async: false,
        data: $("form").serialize(),
        success:
            function(result) {
                if (someLogic){
                    returnValue = true;
                    return;
                }
            },
        error:
            function(errorThrown) {
                alert("Error occured: " + errorThrown);
            }
        });

        return returnValue;
}
