在后台处理数据时，前台页面同时计数显示Proess Bar
使用了layer来显示
用法：
1。引用

<script language="javascript" src="ShowProcessBar.js"></script>

2。在提交Button或<a>或<span> 加扩展属性
IsShowProcessBar="True"
文件ShowProcessBar.js如下

AddProcessbar();
var bwidth=0;
var swidth = document.all.waiting.clientWidth;

function CheckIsProcessBar(obj)
{
if (obj.IsShowProcessBar=="True")
{
return false;
}
else
{
return true;
}
}

function CheckClick(e)
{
if (e == 1)
{
if (bwidthvisibility == 'visible')
{document.all.waiting.style.visibility = 'hidden';
bwidth = 1;}
whichIt = event.srcElement;

while (CheckIsProcessBar(whichIt))
{
whichIt = whichIt.parentElement;
if (whichIt == null)return true;
}


document.all.waiting.style.pixelTop = (document.body.offsetHeight - document.all.waiting.clientHeight) / 2 + document.body.scrollTop;
document.all.waiting.style.pixelLeft = (document.body.offsetWidth - document.all.waiting.clientWidth) / 2 + document.body.scrollLeft;
document.all.waiting.style.visibility = 'visible';
if(!bwidth)CheckClick(1);
bwidth = 1;

}

else
{

if(document.waiting.visibility == 'show')
{document.waiting.visibility = 'hide';
document.rating.visibility = 'hide';
bwidth = 1;}
if(e.target.href.toString() != '')
{
document.waiting.top = (window.innerHeight - document.waiting.clip.height) / 2 + self.pageYOffset;
document.waiting.left = (window.innerWidth - document.waiting.clip.width) / 2 + self.pageXOffset;
document.waiting.visibility = 'show';
document.rating.top = (window.innerHeight - document.waiting.clip.height) / 2 + self.pageYOffset+document.waiting.clip.height-10;
document.rating.left = (window.innerWidth - document.waiting.clip.width) / 2 + self.pageXOffset;
document.rating.visibility = 'show';
if(!bwidth)CheckClick(1);
bwidth = 1;
}
}
return true;
}
}

function AddProcessbar()
{

var Str=""
Str+= "

Str+= "

Str+= ""

document.write(Str)

if(document.all)document.onclick = CheckClick;
}
