How to refresh the page with a link and refresh the page with js

刷新页面通常是使用a链接与js刷新，至于两者在使用中的区别，在接下来的文章中有详细的介绍，感兴趣的朋友可以了解下

1、a链接的使用操作：

复制代码

代码如下:

<a href="javascript:history.go(-1);">返回上一页</a> 
<a href="#top">刷新当前页</a>

#top的效果在我这没起作用，我直接写的刷新当前页倒是起作用了。

2.、JS怎么刷新当前页面

reload 方法，该方法强迫浏览器刷新当前页面。
语法：location.reload([bForceGet])

参数： bForceGet，可选参数，默认为 false，从客户端缓存里取当前页。true, 则以 GET 方式，从服务端取最新的页面, 相当于客户端点击 F5("刷新")

replace 方法，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。
语法： location.replace(URL)

在实际应用的时候，重新刷新页面的时候，我们通常使用： location.reload() 或者是 history.go(0) 来做。因为这种做法就像是客户端点F5刷新页面，所以页面的method="post"的时候，会出现"网页过期"的提示。那是因为Session的安全保护机制。可以想到：当调用 location.reload() 方法的时候， aspx页面此时在服务端内存里已经存在，因此必定是 IsPostback 的。如果有这种应用：我们需要重新加载该页面，也就是说我们期望页面能够在服务端重新被创建，我们期望是 Not IsPostback 的。这里，location.replace() 就可以完成此任务。被replace的页面每次都在服务端重新生成。

你可以这么写： location.replace(location.href);

返回并刷新页面：

复制代码

代码如下:

location.replace(document.referrer); 
document.referrer //前一个页面的URL

不要用 history.go(-1)，或 history.back();来返回并刷新页面，这两种方法不会刷新页面。

附：
Javascript刷新页面的几种方法：

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

自动刷新页面的方法:
1.页面自动刷新：把如下代码加入

区域中

其中20指每隔20秒刷新一次页面.

2.页面自动跳转：把如下代码加入区域中

其中20指隔20秒后跳转到http://www.wyxg.com页面

3.页面自动刷新js版

复制代码

代码如下:

<script language="JavaScript"> 
function myrefresh() 
{ 
window.location.reload(); 
} 
setTimeout(&#39;myrefresh()&#39;,1000); //指定1秒刷新一次 
</script>

JS刷新框架的脚本语句

复制代码

代码如下:

//如何刷新包含该框架的页面用 
<script language=JavaScript> 
parent.location.reload(); 
</script> 
//子窗口刷新父窗口 
<script language=JavaScript> 
self.opener.location.reload(); 
</script> 
(　或　<a href="javascript:opener.location.reload()">刷新</a> ) 
//如何刷新另一个框架的页面用 
<script language=JavaScript> 
parent.另一FrameID.location.reload(); 
</script>

如果想关闭窗口时刷新或者想开窗时刷新的话，在

中调用以下语句即可。

复制代码

代码如下:

<body onload="opener.location.reload()"> 开窗时刷新 
<body onUnload="opener.location.reload()"> 关闭时刷新 
<script language="javascript"> 
window.opener.document.location.reload() 
</script>
