js控制页面跳转的方法

代码如下:

    <script language="javascript" type="text/javascript">
           window.location.href="login.jsp?backurl="+window.location.href; 
    </script>

代码如下:

    <script language="javascript">
alert("返回");
window.history.back(-1);
   </script>

代码如下:

   <script language="javascript">
window.navigate("top.jsp");
  </script>

代码如下:

   <script language="JavaScript">
          self.location='top.htm';
   </script>

代码如下:

   <script language="javascript">
          alert("非法访问！");
          top.location='xx.jsp';
   </script>

代码如下:

<script language="javascript">
var secs = 3; //倒计时的秒数 
var URL ;
function Load(url){
URL = url;
for(var i=secs;i>=0;i--) 
{ 
   window.setTimeout('doUpdate(' + i + ')', (secs-i) * 1000); 
} 
}
function doUpdate(num) 
{ 
document.getElementById('ShowDiv').innerHTML = '将在'+num+'秒后自动跳转到主页' ;
if(num == 0) { window.location = URL; }
}
</script>

代码如下:

<p style="text-indent: 2em; margin-top: 30px;">
系统将在 <span id="time">5</span> 秒钟后自动跳转至新网址，如果未能跳转，<a href="http://www.jb51.net" title="点击访问">请点击</a>。</p>
<script type="text/javascript">  
    delayURL();    
    function delayURL() { 
        var delay = document.getElementById("time").innerHTML;
 var t = setTimeout("delayURL()", 1000);
        if (delay > 0) {
            delay--;
            document.getElementById("time").innerHTML = delay;
        } else {
     clearTimeout(t); 
            window.location.href = "http://www.jb51.net";
        }        
    } 
</script>
