There are N types of page refresh code in js. Next I will introduce you to the code of the page refresh in js, including: Click to refresh the page, regularly refresh pages and other implementation methods. For more information, see.

Let's briefly introduce some page refresh statements.

1 history. go (0)
2 location. reload ()
3 location = location
4 location. assign (location)
5 document.exe cCommand ('refresh ')
6 window. navigate (location)
7 location. replace (location)
8 document. URL = location. href found

Automatically refresh js edition on the timed page

Program code

The Code is as follows: Copy code

<Meta http-equiv = "refresh" content = "20">


Or write it like this

The Code is as follows: Copy code

<Script language = "Javascript">
Function myrefresh ()
{
Window. location. reload ();
}
SetTimeout ('myrefresh () ', 1000); // refresh once per second
</Script>


Window. location. Reload () and window. location. href = window. location. href;

The Code is as follows: Copy code


<A onclick = "javascript: window. location. href = window. location. href;">

<A onclick = "javascript: window. location. reload ();">

The test results are the same. The form is not submitted.

The Code is as follows: Copy code

<Input type = "submit" onclick = "javascript: window. location. reload ();" value = "click" id = "btnVCode"/>
<Input type = "submit" onclick = "javascript: window. location. href = window. location. href;" value = "click" id = "btnVCode"/>

Submit data

Window. location. Reload () should be refreshed. (If data is submitted, the system will prompt whether to submit (yes and no ))
Window. location. href = window. location. href;

It is recommended that you do not use location. reload (), but use location = location, and use showModalDialog and showModelessDialog in the mode window.


Js refresh window: window. location. replace (window. location. href)

The Code is as follows: Copy code


Window. location. reload ();

Window. history. go (0 );

Window. location. assign (window. location. href)

Differences between window. location. href and window. location. replace:

1. html-> 2.html-> 3.html

After the system starts from 1.html to 2.html, there are two buttons in 2. btn1is named w.location.href1_3.html, btn2is named window.location.replace(3.html), then,

When you click btn2to enter 3rd, use unzip history.go(-1##wondo=history.back(); to return 2.html

Experience and differences between window. location. href and window. location. replace

When window. location. href is used, window. history. go (-1) or window. history. back () is used.

When window. location. replace ('url') is used, window. history. go (-1) or window. history. back () is not used.

Window. location. replace ("3.jsp"); is a jump that does not send a request to the server.

Window. history. go (-1); window. history. back (); the method is to decide which page to jump to based on the request recorded by the server.

Window. location. href ("3.jsp"); is the redirect request sent to the server, window. history. go (-1); wondow. history. the back () method determines the page to jump to based on the request recorded by the server


JS refresh framework script statement:

The Code is as follows: Copy code

// How to refresh the page containing the framework
<Script language = JavaScript>
Parent. location. reload ();
</Script>
// Refresh the parent window in the Child Window
<Script language = JavaScript>
Self. opener. location. reload ();
</Script>
(Or <a href = "javascript: opener. location. reload ()"> refresh </a>)
// How to refresh the page of another framework
<Script language = JavaScript>
Parent. Another FrameID. location. reload ();
</Script>

If you want to refresh the window when closing the window or refresh the window when opening the window, you can call the following statement in <body>:

The Code is as follows: Copy code

<Body onload = "opener. location. reload ()"> refresh when opening a window
<Body onUnload = "opener. location. reload ()"> refresh when disabled
<Script language = "javascript">
Zookeeper opener.doc ument. location. reload ()
</Script>


Refresh the page of another framework

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 ();
