我們經(jīng)常使用 window.onload 來處理頁面，當(dāng)頁面加載完成做一些事情。但這個 window.onload 是頁面全部加載完成，甚至包括圖片
1. window.onload = function(){}
2. window.onload ＝ functionName; // [color=red]注意:沒有括號
3. IE:
window.attachEvent("onload",functionName);
FF:
window.addEventListener(); // 參數(shù)怎么寫我忘了, 請自己搜索
body onload="init();"事件是等doucment加載完成再加載相應(yīng)的腳本
document.onreadstatechange()是指當(dāng)對象狀態(tài)變更時觸發(fā)腳本
<script type="text/javascript">
function init() {
// quit if this function has already been called
if (arguments.callee.done) return;
// flag this function so we don't do the same thing twice
arguments.callee.done = true;
// create the "page loaded" message
var text = document.createTextNode("Page loaded!");
var message = document.getElementById("message");
message.appendChild(text);
};
/* for Mozilla */
if (document.addEventListener) {
document.addEventListener("DOMContentLoaded", init, null);
}
/* for Internet Explorer */
/*@cc_on @*/
/*@if (@_win32)
document.write("<script defer src=ie_onload.js><"+"/script>");
/*@end @*/
/* for other browsers */
window.onload = init;
</script>
<p id="message"></p>
示例
<script for=window event=onload>
function inint(){
alert("文檔加載完成")
}
</script>
<script language="Javascript">
function document.onreadystatechange()
{
DoLayout();
window.onresize = DoLayout;
Composition.document.open()
Composition.document.write("<head><style type=\"text/css\">body {font-size: 10.8pt}</style><meta http-equiv=Content-Type content=\"text/html; charset=gb2312\"></head><BODY bgcolor=\"#FFFFFF\" MONOSPACE></body>");
Composition.document.close()
Composition.document.designMode="On"
}
</script>
這兩種加載腳本的方式只針對IE游覽器才有效
<script type="text/javascript">
function init(){
alert("頁面加載完畢！");
}
window.onload=init;
</script>
<html>
<body onload="init()">
</body>
</html>
上面兩種方式任何游覽器都支持
