Several JavaScript page refresh methods
The following is an example of three pages named frame.html, top.html, and bottom.html. Be specific about how to do it.
frame.html consists of two pages: top (top.html) and bottom (bottom.html). The code is as follows:
Copy code The code is as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> frame </TITLE> </HEAD> <frameset rows="50%,50%"> <frame name=top src="top.html"> <frame name=bottom src="bottom.html"> </frameset> </HTML>
Now assume that top.html (i.e. the page above) has seven buttons. To refresh bottom.html (the page below), you can use the following seven statements. It’s up to you which one is easier to use. The code of the
top.html page is as follows:
Customized code The code is as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> top.html </TITLE> </HEAD> <BODY> <input type=button value="刷新1" onclick="window.parent.frames[1].location.reload()"><br> <input type=button value="刷新2" onclick="window.parent.frames.bottom.location.reload()"><br> <input type=button value="刷新3" onclick="window.parent.frames['bottom'].location.reload()"><br> <input type=button value="刷新4" onclick="window.parent.frames.item(1).location.reload()"><br> <input type=button value="刷新5" onclick="window.parent.frames.item('bottom').location.reload()"><br> <input type=button value="刷新6" onclick="window.parent.bottom.location.reload()"><br> <input type=button value="刷新7" onclick="window.parent['bottom'].location.reload()"><br> </BODY> </HTML>
The following is the bottom.html page source code. In order to prove that the page below has indeed been refreshed, a dialog box pops up after the page is loaded.
##Copy code The code is as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> bottom.html </TITLE>
</HEAD>
<BODY onload="alert('我被加载了！')">
<h1 id="This-nbsp-is-nbsp-the-nbsp-content-nbsp-in-nbsp-bottom-html">This is the content in bottom.html.</h1>
</BODY>
</HTML>
Explain:
Copy code The code is as follows:
1. window refers to the current page, for example, in this example it refers to the top.html page. 2.parent refers to the parent page of the current page, which is the frame page that contains it. For example, for this example it refers to framedemo.html.
3.frames is a window object and an array. Represents all subpages within the frame.
4.item is a method. Returns the elements in the array.
5. If the subpage is also a frame page with other subpages inside, then some of the above methods may not work.

Several ways to refresh the page using Javascript:
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
2. Automatically refresh the page1. Page automatically Refresh: Add the following code to the area
20 means refreshing the page every 20 seconds.
2 .Automatic page jump: add the following code to the area
The 20 fingers jump to the http://www.jb51.net page after 20 seconds
3. The page automatically refreshes the js version
<script language="JavaScript">
function myrefresh()
{
window.location.reload();
}
setTimeout('myrefresh()',1000); //指定1秒刷新一次
</script>
3. When writing Servler, Action and other programs in Java, if you want to return to the page (such as opening the window, after the operation is completed, close the current page and refresh the parent page)
Copy code The code is as follows:
1 PrintWriter out = response.getWriter();
2 out.write("<script type=\"text/javascript\">");
3 ////子窗口刷新父窗口
4 out.write("self.opener.location.reload();");
5 //关闭窗口
6 out.write("window.opener=null;");
7 out.write("window.close();");
8 out.write("</script>");
four , JS script statement to refresh the frame 1. How to refresh the page containing the frame using
## Copy the code The code is as follows:<script language=JavaScript>
parent.location.reload();
</script>
2. The child window refreshes the parent window
复制代码 代码如下:
<script language=JavaScript>
self.opener.location.reload();
</script>
3.如何刷新另一个框架的页面用 （上面的实例以说明了）
复制代码 代码如下:
语句1. window.parent.frames[1].location.reload(); 语句2. window.parent.frames.bottom.location.reload(); 语句3. window.parent.frames["bottom"].location.reload(); 语句4. window.parent.frames.item(1).location.reload(); 语句5. window.parent.frames.item('bottom').location.reload(); 语句6. window.parent.bottom.location.reload(); 语句7. window.parent['bottom'].location.reload();
4.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。
<body onload="opener.location.reload()"> 开窗时刷新 <body onUnload="opener.location.reload()"> 关闭时刷新
复制代码 代码如下:
<script language="javascript"> window.opener.document.location.reload()
</script>
JavaScript 实现页面跳转的几种方法：
window.location.href="new.jsp?msg='hello";
self.location='new.jsp?pam='omg';
window.navigate("new.jsp") ;
top.location="show.jsp";The above is the detailed content of Several methods of page refresh using javascript. For more information, please follow other related articles on the PHP Chinese website!
JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Demystifying JavaScript: What It Does and Why It MattersApr 09, 2025 am 12:07 AMJavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
Is Python or JavaScript better?Apr 06, 2025 am 12:14 AMPython is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.
