Document.execcommand (' Refresh ')
Window.navigate (location)
Location.replace (location)
Document. Url=location.href

Today in the project found in the Chrome refresh page since the invalid, after repeated testing found that the "#" character block page refresh
Don't understand? Let's take a look at the demo.

The code is as follows Copy Code

Javascript
$ (function () {
$ (' #reload '). Show (' slow ');
$ (' #o1 '). Click (function () {
Location = Location
})
$ (' #o2 '). Click (function () {
History.go (0)
})
$ (' #o3 '). Click (function () {
Location.reload ()
})
$ (' #o4 '). Click (function () {
Location = Location
})
$ (' #o5 '). Click (function () {
History.go (0)
})
$ (' #o6 '). Click (function () {
Location.reload ()
})
$ (' #o7 '). Click (function () {
Window.location = window.location
return False
})
$ (' #o8 '). Click (function () {
History.go (0)
return False
})
$ (' #o9 '). Click (function () {
Location.reload ()
return False
})
})
Html
<div id= "Reload" > page refreshed </div>
<a href= "#" id= "O1" > Example 1</a>
<a href= "#" id= "O2" > Example 2</a>
<a href= "#" id= "O3" > Example 3</a>
<a href= "javascript:;" id= "O4" > Example 4</a>
<a href= "javascript:;" id= "O5" > Example 5</a>
<a href= "javascript:;" id= "O6" > Example 6</a>
<a href= "#" id= "O7" > Example 7</a>
<a href= "#" id= "O8" > Example 8</a>
<a href= "#" id= "O9" > Example 9</a>

Test results

Firefox all samples flushed properly
Chrome Example 2 Refresh is not valid
opera all samples flushed properly
ie all samples are flush correctly, Example 2 adds "#" characters to the address bar

This time add the "#" character to the address bar, and again the test results are as follows:

Firefox Example 1, example 4, example 7 refresh is not valid, the rest is refreshed normally
Chrome Example 3, example 6, example 9 flush Normal, the rest is not valid
Opera Example 1, example 4, example 7 refresh is not valid, the rest is refreshed normally
IE Example 1, example 4, example 7 refresh is not valid, the rest is refreshed normally

This time it looks like Chrome is playing with personality, and here's how to design a hive to remind you of the following two points:

1. Use "#" as little as possible as a null link, using javascript:;
2. Use Location.reload () to refresh the page only when appropriate. Because the method forces clear caching, increasing the time the page loads.


ways to automatically refresh pages:

1. Page Automatic refresh: Add the following code to the

The code is as follows Copy Code

The code is as follows Copy Code
<meta http-equiv= "Refresh" content= "20;url=http://www.111cn.net" >

20 of which refers to 20 seconds after the jump to the Http://www.111cn.net page

3. Page automatically refresh JS version

The code is as follows Copy Code
<script language= "JavaScript" >
function Myrefresh ()
{
Window.location.reload ();
}
SetTimeout (' Myrefresh () ', 1000); Specify 1 seconds to refresh once
</script>
