Allan Jardine | Reflections | Visual Event
Events in Javascript are often seen as a bit of an enigma. This is odd given that Javascript is very much an event driven language, but it is typically down to their complex nature and difficulty to debug. To this end I've created Visual Event to help track events which are subscribed to DOM nodes. Update: Visual Event 2 is now available and released as open source. Introduction When working with

Haskell functions for Javascript
These are Haskell's functions ported to javascript. Some are missing and some don't behave exactly the same. You can try them with a console (firebug or others). All functions can be curried!! All list(array) functions do work on regular strings: filter( isVowel, 'hey how are you' ) == 'eoaeou'; take( 5, 'abcdefghi' ) == 'abcde'; maximum( 'ajcdbe' ) == 'j'; The function length is called length' Mo
Firefox 4: easier JS form handling with FormData – Mozilla Hacks - the Web developer blog
This feature has landed in Mozilla Central (trunk) and only available with a Firefox Nightly Build for the time being. XMLHttpRequest Level 2 (editor’s draft) adds support for the new FormData interface. FormData objects provide a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest send() method in “mult

JavaScript syntax - Better JavaScrirpt syntax support : vim online
Hi JavaScript and VIM funs, If you want to use VIM to edit/view the JavaScript files, you should have this one. Replace it with the javascript syntax file included with the VIMRUNTIME. Why it is here: Because I found that the originaly one which packed with the VIMRUNTIME didn't work very well for the JS files in Mozilla Browser/SeaMonkey/Firefox and Dojo. So I decided to some refine on it. Hope i
