javascript

What is popping up in js window.open is the cache page problem from last time

To solve the problem that a window.open page will save the cache.

Add the following code to the head TAB of the page


<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Cache-Control" content="no-cache" />
<meta http-equiv="Expires" content="0" />
