按下返回按钮后停止页面刷新

Question

Is there any way to stop a web page from refreshing when it is displayed after someone presses the back button?

My web page shows different information every time it is refreshed. I want it to show whatever it was showing before the user moved to another page.

Is this possible? If so how?

Answer 1

No.

The contents of the window when the 'back' button is pressed is actually data your browser has cached so preventing 'back' is not going to help.

You could maybe use a hash though.

go to

stackoverflow.com

then go to

stackoverflow.com#foo

then go to

stackoverflow.com#foobar

If you hit the back button you'll notice the hash changes but the page does not refresh.

Sorry about the formatting. Blame SO!
