在Javascript中定义一个带有命名空间的类

Question

请参阅/sf/answers/27141341/,

// Define a class like this
function Person(name, gender){

   // Add object properties like this
   this.name = name;
   this.gender = gender;
}

// Add methods like this.  All Person objects will be able to invoke this
Person.prototype.speak = function(){
    alert("Howdy, my name is" + this.name);
}

// Instantiate new objects with 'new'
var person = new Person("Bob", "M");

// Invoke methods like this
person.speak(); // alerts "Howdy, my name is Bob"

如何定义命名空间？

Answer 1

您只需创建一个包含所有类/函数的新对象:

var myNamespace = {};

myNamespace.Person = function (name, gender) {
    // Add object properties like this
    this.name = name;
    this.gender = gender;
}

myNamespace.Person.prototype.speak = function() {
    alert("Howdy, my name is" + this.name);
}

// Instantiate new objects with 'new'
var person = new myNamespace.Person("Bob", "M");

// Invoke methods like this
person.speak(); // alerts "Howdy, my name is Bob"

MDN有一篇解释JavaScript命名空间的文章.
