Find Which JavaScript framework
http://blog.olicio.us/2008/11/08/wtframework-bookmarklet/
Ever wondered which JavaScript framework was used on a specific website but was too lazy to check the source code for the answer? Fear no more WTFramework is here.
Here we have the work of my life – where by saying life I mean 20 minutes of it. This is a pretty simple and straight–forward bookmarklet.
Say you come across a website, see a few pretty cool effects (right click to ensure it’s not Flash driven) and you’d like to know which of the some three fabulous JavaScript frameworks (MooTools, Yahoo User Interface, jQuery, the infamous Scriptaculous, Dojo Toolkit, Mochikit, etc.) are being used to rise the magic.
Typically, you’d have to look for the script tag in the source. Well forget about it, now you have WTFramework – one click and a info pops–up informing which framework are we dealing with.
Just drag and drop the link onto your Bookmark Bar.
