How do you add functions to $(window).load()?

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 o开发者_运维技巧f 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?

They actually do stack in the order specified. Here's an example : http://jsfiddle.net/73D9Z/

I've used window.ready()

$(window).ready(function(){
    alert('window ready 1');
});

$(window).ready(function(){
    alert('window ready 2');
});

$(document).ready(function(){
    alert('document ready 1');
});

$(document).ready(function(){
    alert('document ready 2');
});

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();
        }
    }
}

$(window).load() gets executed after a page is rendered.

$(document).ready(handler) executes the function passed as parameter, after the DOM is ready and before the page is rendered.
