javascript editing prompt -

-

I am creating a web application in which I must show the user's edit signal to navigate through the page.

I want to show it only when the user edits some values ​​on that page and does not save the change, then the prompt "Do you want to save changes?" Will ask. Otherwise, the prompt does not appear if it is saved.

A processing signal similar to Microsoft Word / Excel informs you that you are making changes and you want to proceed.

Please solve the solution faster?

You can use onbeforeunload :

Although support is limited because it is based on some invention of Microsoft and others have copied it. It is not possible to do whatever you want in a browser that does not support this incident.

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code.

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
