For example, I have var menu_ready = false;. I have an ajax function that sets menu_ready to true when the ajax stuff is done:

//set up event listener here

$(...).load(..., function() {
    ...
    menu_ready = true;
}

How do I set up an event listener that waits for menu_ready to be true?

    WARNING My answer below is from a period slightly prior to the sailing of the Mayflower. It’s a bad answer. I can’t remove it because it was accepted, and the system won’t let me remove an accepted answer. I could edit it to make it better, but why do that when others have given solid answers below? Bottom line: scroll past this to a more fulfilling life. 🙂

    One way is continual polling:

    function checkMenu() {
    if (!menu_ready) {
        setTimeout("checkMenu();", 1000);
        return;
    } else {
        // menu_ready is true, so do what you need to do here.
    }
}

    and…

    <body onload="checkMenu();">
