Hi ALL
Urgent requirement..........
If the back button is used how to present t the user with pop-up window?.

You can use the onbeforeunload or onunload event to trap the page being left but there's no specific way to know if it was because of the back button or just the browser going elsewhere or being closed.

A popup now though will be blocked by most blockers including IE6 in normal mode as it is event triggered rather than user initiated.

Please don't mark posts as Urgent, especially all your posts.
Everyone's problems are urgent to them and you could easily have Googled for this if it were that important.

Hii mikedeepak!!!

 You can trap the back button at some extent.
Whenever page unload put it's page identity value in cookies.
Whenever user click on the back button check whether page identity is on/off.If on then put ur javascript alert/popup in ur page onload method.Again be sure to remove cookies value when user closes the browser or logout from your website.
Note;-User can disable cookies.

If you have any other alternatives plz let me know
Hope this will help you



Cheers :)
