js

Let’s look at a simple example first:
The following takes three pages named frame.html, top.html, and bottom.html as an example to explain 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:

 
< HEAD> 
 frame

Now assume that top.html (i.e., the page above) has seven buttons to refresh bottom.html (i.e., the page below). You can use the following seven statements. It’s up to you which one is easier to use.
Statement 1. window.parent.frames[1].location.reload();
Statement 2. window.parent.frames.bottom.location.reload();
Statement 3. window.parent .frames["bottom"].location.reload();
Statement 4. window.parent.frames.item(1).location.reload();
Statement 5. window.parent.frames.item ('bottom').location.reload();
Statement 6. window.parent.bottom.location.reload();
Statement 7. window.parent['bottom'].location.reload() ;

The code of the top.html page is as follows:

Copy the code The code is as follows:

top.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. The code of

bottom.html page is as follows:

Copy the code The code is as follows:

 
 
 
 
 bottom.html < ;/TITLE> <br></HEAD> <br><BODY onload="alert('I was loaded!')"> <br><h1>This is the content in bottom.html. </h1> <br></BODY> <br></HTML> <br>
</div>
<br>Explain: <br>1.window refers to the current page, for example, in this example it refers to the top.html page. <br>2.parent refers to the parent page of the current page, that is, the frame page containing it. For example, for this example it refers to framedemo.html. <br>3.frames is a window object and an array. Represents all subpages within the frame. <br>4.item is a method. Returns the elements in the array. <br>5. If the subpage is also a frame page with other subpages inside, then some of the above methods may not work. <br><br>Attachment: <br> Several ways to refresh the page using Javascript: <br>1 history.go(0) <br>2 location.reload() <br>3 location=location <br>4 location .assign(location) <br>5 document.execCommand('Refresh') <br>6 window.navigate(location) <br>7 location.replace(location) <br>8 document.URL=location.href <br><br>Methods to automatically refresh the page: <br>1. Automatically refresh the page: Add the following code to the <head> area <br><meta http-equiv="refresh" content="20"> <br>20 of them means refreshing the page every 20 seconds. <br><br>2. Automatic page jump: add the following code to the <head> area <br><meta http-equiv="refresh" content ="20;url=HTTP://www.wyxg.com"> <br> Among them, 20 means jumping to HTTP://www after 20 seconds. wyxg. com page <br><br>3. The page automatically refreshes the js version <br><script language="JavaScript"> <br>function myrefresh() <br>{ <br>window.location.reload(); <br>} <br>setTimeout('myrefresh()',1000); //Specify a refresh time of 1 second<br></script> <br><br>How ASP.NET outputs the refresh parent window script statement<br><div class="codetitle">
<span><a style="CURSOR: pointer" data="61285" class="copybut" id="copybut61285" onclick="doCopy('code61285')"><u>Copy code</u></a></span> The code is as follows:</div>

Response.Write("<script language=javascript>opener.window.navigate(''The page you want to refresh.asp'');</script>") <br>
