       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="http://img.jcwcn.com/attachment/portal"></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 (bwidth<swidth*0.98){
  bwidth += (swidth - bwidth) * 0.025;
  if (document.all)document.sbar.width = bwidth;
  else document.rating.clip.width = bwidth;
  setTimeout('CheckClick(1);',150);
  
  }
  }
  else
  {
  if(document.all)
  {
  if(document.all.waiting.style.visibility == '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+= "<div id=waiting style=position:absolute;top:50px;left:100px;z-index:1;visibility:hidden >";
  Str+= "<layer name=waiting visibility=visible zIndex=2 >"
