window.location跳转+替换+刷新
 一、最外层top跳转页面,适合用于iframe框架集
top.window.location.href("${pageContext.request.contextPath}/Login_goBack");
 ============================================================================================
 二、window.location.href和window.location.replace的区别 
 1.window.location.href=“url”:改变url地址; 
 2.window.location.replace(“url”):将地址替换成新url,该方法通过指定URL替换当前缓存在历史里(客户端)的项目,
 因此当使用replace方法之后,你不能通过“前进”和“后 退”来访问已经被替换的URL,这个特点对于做一些过渡页面非常有用!
 三、强制页面刷新 
 1.window.location.reload():强制刷新页面,从服务器重新请求! 
 ============================================================================================
 四、window.location.reload();页面实现跳转和刷新 
 1 history.go(0)
 2 location.reload()
 3 location=location
 4 location.assign(location)
 5 document.execCommand('Refresh')
 6 window.navigate(location)
 7 location.replace(location)
 8 document.URL=location.href
 这几个都可以刷新
 window.location.reload();刷新
 window.location.href=window.location.href;刷新
 window.close();关闭窗口,不弹出系统提示,直接关闭 
 window.close()相当于self属性是当前窗口
 window.parent.close()是parent属性是当前窗口或框架的框架组
 页面实现跳转的九种方法实例:
 
<html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <title>navigate</title>
 <script language="javascript">
     setTimeout('window.navigate("top.html");',2000);
     setTimeout('window.document.location.href="top.html";',2000);
     setTimeout('window.document.location="top.html";',2000);
     setTimeout('window.location.href="top.html";',2000);
     setTimeout('window.location="top.html";',2000);
     setTimeout('document.location.href="top.html";',2000);              
     setTimeout('document.location="top.html";',2000);
     setTimeout('location.href="top.html";',2000);
     setTimeout('location.replace("top.html")',2000);
     //window对象
         //document对象
             //location对象
                 //href属性
                 //1.window.document.location.href
                 //2.window.document.location
                 //3.window.location.href
                 //4.window.location
                
                 //5.document.location.href
                 //6.document.location
                 //7.location.href
                 //8.window.navigate
                 //9.location.replace
                 //只要使用location方法,和任意的window对象,location对象,href属性连用,都可以页面的跳转 
 </script>
 </head>
 <body>
 页面将在2秒后跳转
 </body>
 </html>
 解释:
 location是个对象,比如本页的document.location和window.location的属性有    
   location.hostname   =   community.csdn.net 
   location.href   =    
   location.host   =   community.csdn.net 
   location.hash   =   
   location.port   =   
   location.pathname   =   /Expert/topic/4033/4033372.xml 
   location.search   =   ?temp=2.695864E-02 
   location.protocol   =   http: 
   可见href是location的属性,类别是string。
