Detecting Unsaved Work in Javascript


This project will teach you how to trap your user with an unsaved work. It has only few lines of code in javascript.

If the user has unsaved work and application that is not completed and attempt to close the window, the pop up message will appear asking if you want to leave the page or stay on the page. Simple yet very useful.

Hope you learn from this.


Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
