Return to previous page and Refresh page method

Original address: http://www.zixuephp.com/html/javascript/2014_09/1642.html

PHP implements 3 effective ways to return to previous page functionality

Header (Location: The path to your previous page); Note that there is no output before this function

Header (Location:.getenv ("Http_referer")); Return to its invocation page

echo "<script>alert (' Write anything '); History.go ( -1);</script>";

JS Reload page, refresh locally, return to previous page

The code is as follows	Copy Code
<a href= "Javascript:history.go ( -1)" > Back </a> <a href= "Javascript:location.reload ()" > Reload page, local refresh </a> <a href= "Javascript:history.go ( -1); Location.reload ()" > Back to previous Reload page, local refresh </a>

Return to the first two pages and refresh the JS code should be how to write.

JS method

The code is as follows	Copy Code
<a href= "#" onclick= "Self.location=document.referrer;" > Back </a>

How the ASP automatically returns and refreshes:

The code is as follows	Copy Code
Response. Write ("<script language=javascript>self.location=document.referrer;</script>")

Typically used to submit an action to a page and then return to the previous page and refresh!

PHP practices

The code is as follows	Copy Code
echo "<script>alert (' exit succeeded! '); Location.href= ' ". $_server[" Http_referer "]." '; </script> ";

Set the delete success to return to the previous page and refresh

The code is as follows	Copy Code
if ($query) { $page = "listrenwu.php"; <!---this way will not refresh and will only be returned as-is echo "<script>alert (' deletion succeeded '); History.go ( -1) </script>"; <!--//set to return to the previous page after successful deletion and refresh-->--> echo "<script>alert (' delete succeeded '); window.location =" ". $page." "; </script> "; }
