window.onload 加載完畢的問題及解決方案(下)

接上篇,其它方法:
一、在IE中還可以在onreadystatechange事件里進行判斷
http://www.thefutureoftheweb.com/blog/adddomloadevent
這里有Jesse Skinner寫了一段獨立的腳本函數來解決各種瀏覽器的onload問題,。
http://img.jb51.NET/jslib/adddomloadevent.js
復制代碼 代碼如下:
/*
* (c)2006 Jesse Skinner/Dean Edwards/Matthias Miller/John Resig
* Special thanks to Dan Webb's domready.js Prototype extension
* and Simon Willison's addLoadEvent
*
* For more info, see:
* http://www.thefutureoftheweb.com/blog/adddomloadevent
* http://dean.edwards.name/weblog/2006/06/again/
* http://www.vivabit.com/bollocks/2006/06/21/a-dom-ready-extension-for-prototype
* http://simon.incutio.com/archive/2004/05/26/addLoadEvent
*
*
* To use: call addDOMLoadEvent one or more times with functions, ie:
*
* function something() {
* // do something
* }
* addDOMLoadEvent(something);
*
* addDOMLoadEvent(function() {
* // do other stuff
* });
*
*/

addDOMLoadEvent = (function(){
// create event function stack
var load_events = [],
load_timer,
script,
done,
exec,
old_onload,
init = function () {
done = true;

// kill the timer
clearInterval(load_timer);

// execute each function in the stack in the order they were added
while (exec = load_events.shift())
exec();

if (script) script.onreadystatechange = '';
};

return function (func) {
// if the init function was already ran, just run this function now and stop
if (done) return func();

if (!load_events[0]) {
// for Mozilla/Opera9
if (document.addEventListener)
document.addEventListener("DOMContentLoaded", init, false);

// for InterNET Explorer
/*@cc_on @*/
/*@if (@_win32)
document.write("<script id=__ie_onload defer src="http://0" src="http://0"><//scr"+"ipt>");
script = document.getElementById("__ie_onload");
script.onreadystatechange = function() {
if (this.readyState == "complete")
init(); // call the onload handler
};
/*@end @*/

// for Safari
if (/WebKit/i.test(navigator.userAgent)) { // sniff
load_timer = setInterval(function() {
if (/loaded|complete/.test(document.readyState))
init(); // call the onload handler
}, 10);
}

// for other browsers set the window.onload, but also execute the old window.onload
old_onload = window.onload;
window.onload = function() {
init();
if (old_onload) old_onload();
};
}

load_events.push(func);
}
})();

二、另外還有在IE中的doScroll的,這是種方法只對IE有作用,而且它是一種hack方法。

在MSDN:About Element Behaviors 我們可以看到
復制代碼 代碼如下:
When the ondocumentready event fires, the document has been completely parsed and built. Initialization code should be placed here if the component needs to navigate the primary document structure. The ondocumentready event notifies the component that the entire page is loaded, and it fires immediately before the onload event fires in the primary document.
A few methods, such as doScroll, require the primary document to be completely loaded. If these methods are part of an initialization function, they should be handled when the ondocumentready event fires.

http://Javascript.nwbox.com/IEContentLoaded/
復制代碼 代碼如下:
/*
*
* IEContentLoaded.js
*
* Author: Diego Perini (diego.perini at gmail.com) NWBOX S.r.l.
* Summary: DOMContentLoaded emulation for IE browsers
* Updated: 05/10/2007
* License: GPL/CC
* Version: TBD
*
*/

// @w    window reference
// @fn    function reference
function IEContentLoaded (w, fn) {
    var d = w.document, done = false,
    // only fire once
    init = function () {
        if (!done) {
            done = true;
            fn();
        }
    };
    // polling for no errors
    (function () {
        try {
            // throws errors until after ondocumentready
            d.documentElement.doScroll('left');
        } catch (e) {
            setTimeout(arguments.callee, 50);
            return;
        }
        // no errors, fire
        init();
    })();
    // trying to always fire before onload
    d.onreadystatechange = function() {
        if (d.readyState == 'complete') {
            d.onreadystatechange = null;
            init();
        }
    };
}

在jQuery的源碼中,針對Mozilla, Opera 和webkit用的是DOMContentLoaded,也就是上一篇中第一種;

而對IE用的是doScroll的方法。
