So I’m a fairly decent javascript programmer and I’ve just recently finished working on a fairly big web application that involved writing quite a bit of javascript. One of the things I can across when I was debugging my script was that there were some namespace conflicts with my various global variables I used throughout my script. Essentially, my javascript file was structured as such:

global var a
global var b
global var c
function1(){}
function2(){}
function3(){}

with a jQuery document on-ready function to bind various events to buttons in my html and call my functions as event handler callbacks.

Some people recommended encapsulating my entire script in one gigantic function to prevent any scope-related errors. I couldn’t quite figure out exactly what that would entail. Any tips are appreciated as I am about to create another web app that will involve quite a bit of AJAX page loads to avoid browser refreshes and DOM manipulation bound to various events. Thanks!

    I recommend reading the jQuery plugin authoring guide (I also recommend you consider using jQuery if you are not)

    http://docs.jquery.com/Plugins/Authoring

    BTW this been asked many times (not a criticism for re-asking)

    I also highly recommend you read about jQuery live plugin for register DOM events(I guess its built-in now):
    http://api.jquery.com/live/
    (this will minimize the nasty need for state management of unbinding and rebinding your DOM nodes).
