Question

I am looking for a good way to perform sleep() or waitForEvent() in GWT\Javascript.
I am performing a http request and i don’t want to continue execution of the code before the request ends.

I am using an existing code so it is very problematic to re-factor it to wait for an event.

Are there any solutions?

use a flow control library like Frame.js.

    Frame(function(next){
        $.ajax({
            url:'authenticate.api',
            data: id,
            success: next
        });
    });
    Frame(function(next, ajaxResponse){
        userRole = ajaxResponse.responseText.userRole;
    });
