Display popup window when closing "X" web browser
Hi All - how I can display a popup window when user press "X" from web browser.
I know how to create popups windows but where I can code the popup window when the user close the browser?
e.g. I press at the top right the web browser "X" to close the browser, how I can display a popup asking if they want to SAVE the data before closing the browser.
Can you have a look at below mentioned thread and give your solution:
