模块模式可以提供软件架构，为不断增长的代码提供组织形式。JavaScript没有提供package的语言表示，但我们可以通过模块模式来分解并组织 代码块，这些黑盒的代码块内的功能可以根据不断变化的软件需求而不断的被添加，替代和删除。模块模式由几种我们已经介绍过的模式共同组成：
MYAPP.namespace(‘MYAPP.utilities.array‘);
MYAPP.utilities.array = (function () {
return {
// todo...
};
}());
MYAPP.utilities.array = (function () {
return {
inArray: function (needle, haystack) {
// ...
},
isArray: function (a) {
// ...
}
};
}());
MYAPP.namespace(‘MYAPP.utilities.array‘);
MYAPP.utilities.array = (function () {
// dependencies
var uobj = MYAPP.utilities.object,
ulang = MYAPP.utilities.lang,
// private properties
array_string = "[object Array]",
ops = Object.prototype.toString;
// private methods
// ...
// end var
// optionally one-time init procedures
// ...
// public API
return {
inArray: function (needle, haystack) {
for (var i = 0, max = haystack.length; i < max; i += 1) {
if (haystack[i] === needle) {
return true;
}
}
},
isArray: function (a) {
return ops.call(a) === array_string;
}
// ... more methods and properties
};
}());
MYAPP.utilities.array = (function () {
// private properties
var array_string = "[object Array]",
ops = Object.prototype.toString,
// private methods
inArray = function (haystack, needle) {
for (var i = 0, max = haystack.length; i < max; i += 1) {
if (haystack[i] === needle) {
return i;
}
}
return ?1;
},
isArray = function (a) {
return ops.call(a) === array_string;
};
// end var
// revealing public API
return {
isArray: isArray,
indexOf: inArray
};
}());
MYAPP.namespace(‘MYAPP.utilities.Array‘);
MYAPP.utilities.Array = (function () {
// dependencies
var uobj = MYAPP.utilities.object,
ulang = MYAPP.utilities.lang,
// private properties and methods...
Constr;
// end var
// optionally one-time init procedures
// ...
// public API -- constructor
Constr = function (o) {
this.elements = this.toArray(o);
};
// public API -- prototype
Constr.prototype = {
constructor: MYAPP.utilities.Array,
version: "2.0",
toArray: function (obj) {
for (var i = 0, a = [], len = obj.length; i < len; i += 1) {
a[i] = obj[i];
}
return a;
}
};
// return the constructor
// to be assigned to the new namespace
return Constr;
}());
var arr = new MYAPP.utilities.Array(obj);
3. 把global对象引入到模块中
MYAPP.utilities.module = (function (app, global) {
// references to the global object
// and to the global app namespace object
// are now localized
}(MYAPP, this));
