Edit Question
Title
Body
Here in stackoverflow, if you started to make changes then you attempt to navigate away from the page, a javascript confirm button shows up and asks: "Are you sure you want to navigate away from this page?" blee blah bloo... Has anyone implemented this before, how do I track that changes were committed? I believe I could do this myself, I am trying to learn the good practices from you the experts. I tried the following but still doesn't work: <html> <body> <p>Close the page to trigger the onunload event.</p> <script type="text/javascript"> var changes = false; window.onbeforeunload = function() { if (changes) { var message = "Are you sure you want to navigate away from this page?\n\nYou have started writing or editing a post.\n\nPress OK to continue or Cancel to stay on the current page."; if (confirm(message)) return true; else return false; } } </script> <input type='text' onchange='changes=true;'> </input> </body> </html> Can anyone post an example?
