js网页进度条等待特效

本特效共分三步:
1.在<head></head>中加入:
<SCRIPT type=text/javascript>
<!--
var ie5 = (document.all && document.getElementsByTagName);
var step = 0;
function setSB(v, el, inforEl, message) {
if (ie5 || document.readyState == "complete") {
filterEl = el.children[0];
valueEl = el.children[1];
if (filterEl.style.pixelWidth > 0) {
var filterBackup = filterEl.style.filter;
filterEl.style.filter = "";
filterEl.style.filter = filterBackup;
}
filterEl.style.width = v + "%";
valueEl.innerText = v + "%";
inforEl.innerText = message;
}
}
function setSBByStep(v, el, inforEl, message) {
if (ie5 || document.readyState == "complete") {
step = step + v;
filterEl = el.children[0];
valueEl = el.children[1];
if (filterEl.style.pixelWidth > 0) {
var filterBackup = filterEl.style.filter;
filterEl.style.filter = "";
filterEl.style.filter = filterBackup;
}
filterEl.style.width = step + "%";
valueEl.innerText = step + "%"
inforEl.innerText = message;
}
}
function fakeProgress(v, el) {
if (v >= 101)
location.href="http://www.roeyuta.com/Ch";
else {
setSB(v, el, infor, "欢迎访问 荣盛达电源 荣御达电源,页面载入中,请稍等!");
window.setTimeout("fakeProgress(" + (v + 1) + ", document.all['" + el.id + "'])", 150);
}
}
//-->
</SCRIPT>
2.在<body>中加入:onload=fakeProgress(0,sb)
<BODY onload=fakeProgress(0,sb)>
3.在<body></body>中加入:
<DIV align=center>
<DIV id=sb
style="BORDER-RIGHT: #ffffff 1px solid; BORDER-TOP: #ffffff 1px solid; BACKGROUND: #99ccff; BORDER-LEFT: medium none; WIDTH: 400px; BORDER-BOTTOM: #cccccc 1px solid; HEIGHT: 14px; TEXT-ALIGN: left">
<DIV id=sbChild1
style="FILTER: Alpha(Opacity=0, FinishOpacity=80, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0); OVERFLOW: hidden; WIDTH: 100%; POSITION: absolute; HEIGHT: 12px">
<DIV style="BACKGROUND: #000000; WIDTH: 100%" ;height:12px; overflow:
hidden></DIV></DIV>
<DIV
style="FONT-SIZE: 10px; WIDTH: 400px; COLOR: white; FONT-FAMILY: arial; POSITION: absolute; HEIGHT: 14px; TEXT-ALIGN: center"></DIV></DIV>
<P></P>
<DIV id=infor
style="FONT-SIZE: 11px; WIDTH: 100%; COLOR: #999999; FONT-FAMILY: arial; POSITION: relative; HEIGHT: 14px; TEXT-ALIGN: center"></DIV></DIV>
