How to jump to the logon page under the IFRAME framework

In the IFRAME framework, navigation to the logon interface always jumps to the subinterface, similar

Try respon. Redirect,

I use JS functions, but the jump code is written in the CS file. With respose. Write (), JS functions are not executed at all.

Finally, I saw an article, using respon. Redirect () in the background, and adding js to the logon interface, as shown in the following code:

<Script language = "JavaScript" type = "text/JavaScript">

If (window! = Top)

Top. Location. href = location. href;

</SCRIPT>

Or

<SCRIPT type = "text/JavaScript">
If (window. Top! = Window. Self ){
Window. Top. Location. href = Window. Self. Location. href;
}
</SCRIPT>
