JavaScript optimized--06 mode (object)

Namespace mode:

• Advantages: Can solve the naming confusion and third-party conflict;
• Cons: Long nesting results in longer query times; more characters;
• Universal namespace functions:

  var MyApp = MyApp | | {}; Myapp.namespace = function (ns_string) {    var parts = ns_string.split ('. ');    parent = MYAPP;      if (parts[0] = = = ' MYAPP ') {        parts = parts.slice (1);   }   for (var  i = 0; i < parts.length; i++) {      if (typeof parent[parts[i]] = = = ' undefined ') {          PARENT[PARTS[I]]
       = {};      }       Parent = Parent[parts[i]];   }   return parent; var module2 = myapp.namespace (' MYAPP.modules.module2 ');

• Declaring dependencies: Although a modular naming has been made, the declaration of dependency can be more optimized

  For: MYAPP, MYAPP.util.Event, myapp.util.dom;//at the top of a function or module var  myFunc = function () {   var Event = MYAPP.util.Event;   

  The speed of parsing local variables is faster than resolving global variables;

• Private properties and Privileged methods

  function Gadget () {   var name = ' IPod ';   This.getname = function () {        return name;   }}

  Note that if the private property setting is an object and is read-only, do not return it directly, but return its shallow copy;
