Question

Just curious if there’s an easy way to add functions to the $(window).load() event before it has fired. For example, if you call $(window).load() twice in the beginning of the page, only the function of the second call will execute onload.

Is there some sort of tool built into jQuery for adding to the onload event instead of replacing it? If so, how about for the $(document).ready() call?

function windowLoad(func) {
    var oldonload = window.onload;
    if (typeof window.onload != 'function') {
        window.onload = func;
    } else {
        window.onload = function() {
            if (oldonload) {
                oldonload();
            }
            func();
        }
    }
}

function documentReady(func) {
    var oldonload = document.ready;
    if (typeof document.ready != 'function') {
        document.ready = func;
    } else {
        document.ready = function() {
            if (oldonload) {
                oldonload();
            }
            func();
        }
    }
}
