<h3><span id="redirectClue">3</span>秒后自动跳转到XXX页面......</h3>
       
       <script type="text/javascript">
       var secs = 3;
       var time;
       function countDown(secs){
        
        if(secs>0) {
         document.getElementById("redirectClue").innerHTML=secs;
         secs--;
         time = setTimeout("countDown("+secs+")",1000);
        }else{
         clearTimeout(time);
         location.href="http://www.kl21.com";
        }
       }
       countDown(secs);

       </script>

 

 

String.prototype.CheckPostCode = function()
{
    var MyNumber =  this.search(/^[1-9]{1}[0-9]{5}$/);
    if(MyNumber == -1)
        return false;
    return true; 
}
function ToCheck()

if(MyText.value.CheckPostCode())

}
}

 

 

<script language= "javascript " for= "window " event= "onload ">

EVENT   event   设置或获取脚本编写用于的事件   
FOR   htmlFor   设置或获取绑定到事件脚本的对象。 

可以这样理解。 

<script   language= "javascript "   for= "window "   event= "onload "> 
相当于 
<script   language= "javascript "> 
//   绑定 
window.attachEvent( "onload ",function()   { 
//   TODO 
}) 
</script> 

 

FOR 后面跟的是一个控件的ID，比如<object id="window"><object>这可能是一个组件。比如在线编辑器，word内嵌的编辑器等。

EVENT是指下面的JavaScript脚本是在页面载入的时候调用
