有時候，在送出或點選一個連結後，由于種種原因，可能會在原來的頁面上停留一段時間，如果不知道的朋友還以為是打不開。
現在可以用下面的方法，來給這些朋友一個提示，告訴他們系統正在處理資料~~~~~
在背景處理資料時，前台頁面同時計數顯示Proess Bar
使用了layer來顯示!
在送出Button或<A>或<span> 加擴充屬性
以下是引用片段：
IsShowProcessBar="True"
詳細代碼如下：
ShowBar.js：
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 >"
Str+= "<table
Str+= " <tr>"
Str+= " <td bgcolor=#E0E0E0 height=30px width=300px align=center>"
Str+= " <font color=black>系統正在處理中...</font>"
Str+= " </td>"
Str+= " </tr>"
Str+= " <tr>"
Str+= " <td bgcolor=#E0E0E0>"
Str+= " <img width=1 height=10 name=sbar style="background-color:#6699cc" mce_style="background-color:#6699cc">"
Str+= " </td>"
Str+= " </tr>"
Str+= "</table> "
Str+= "</layer>"
Str+= "</div>"
document.write(Str)
if(document.all)document.onclick = CheckClick;
}
