js判断页面是否加载完毕

用 document.readyState == "complete" 判断页面是否加载完成。
document.onreadystatechange = function(){

if(document.readyState=="complete")

{

alert('加载完毕');

}

}

Js代码







var leftDocument=window.parent.frames("leftFrame").document; if(leftDocument.readyState == 'loaded' || leftDocument.readyState == 'complete') { leftDocument.getElementById("notes").style.display = 'block'; leftDocument.getElementById("others").style.display = 'none'; }

var leftDocument=window.parent.frames("leftFrame").document;
if(leftDocument.readyState == 'loaded' || leftDocument.readyState == 'complete')
{
leftDocument.getElementById("notes").style.display = 'block';
leftDocument.getElementById("others").style.display = 'none';
}

Js代码







<script language="javascript">

if (document.readyState=="complete")
{
AdjustImageSize();
}
else
{
document.onreadystatechange = function()
{

if (document.readyState == "complete")
{
AdjustImageSize();
}
}
}

function AdjustImageSize()
{
var imageWidth = document.all["SendPic"].width;
var imageHeight = document.all["SendPic"].height;

if (imageWidth == 0 && imageHeight == 0)
{
document.write ("图片下载失败，请刷新！");
return;
}

if (imageWidth > 160 || imageHeight > 160)
{
if (imageWidth > imageHeight)
{
k = 160 / imageWidth;
imageHeight = imageHeight * k;
imageWidth = 160;
}
else
{
k = 160 / imageHeight;
imageWidth = imageWidth * k;
imageHeight = 160;
}

document.all["ImgResized"].value = "1";
}

document.all["SendPic"].width = imageWidth;
document.all["SendPic"].height = imageHeight;

document.all["ImgWidth"].value = imageWidth;
document.all["ImgHeight"].value = imageHeight;
}
</script>
