javascript - IE won't toggle element -

-

I have javascript on this page to toggle between a java and switch between two images 

  & lt; Script type = "text / javascript" & gt; Function ToggleArchive () {document.getElementById ('Cat'). Toggle (); Var image = document.getElementById ('arrows'); If (image.src == 'bullet_arrow_down.png') {image.src = 'bullet_arrow_up.png'; } Other {image.src = 'bullet_arrow_down.png'; }} & Lt; / Script & gt;

Works fine on modern browsers, but IE says there is an error in that line 

  document.getElementById ('cat'). Toggle ();

So it does not toggle the div nor switches the image. What is the plan?

It seems that as you are using prototype JS library, the library will add methods of DOM elements In this particular case, it is adding HTMLElement.prototype.toggle . The DOM prototype is supported only in IE8 and later and should be rendering in standard mode. To make it work in all browsers, use getElementById () : 

  $ ('cat') instead of  $ ()  method Please. ') .toggle ();

Obfuscating Python code? -

-
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. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
