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 = http://community.csdn.net/Expert/topic/4033/4033372.xml?temp=2.695864E-02
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。
