Ajax|javascript in JavaScript You can use the Function keyword to define a "class" and how to add members to a class. A variable or method referenced within a function through the this pointer becomes a member of the class, for example: function

JavaScript we know the prototype properties of objects in JScript, which are used to return references to object type prototypes. We use the prototype property to provide a set of basic functions for the object's class. And a new instance of the

Ajax|javascript Or to decide on the title of Ajax, after all, many people will use this keyword search. Although I think this is just a hype concept, but have to admit that Ajax is more convenient to call. So I'm not going to elaborate on the

Backbone.events Overview The backbone.events object contains methods that help observer design patterns and a variable observer pattern that invokes pub/sub. These features allow different classes of objects (JavaScript objects) created by backbone

Backbone constructors I say backbone is simple because backbone only four constructors can be typically instantiated (basically, they are first inherited or subcategory). These four constructors include: Backbone.model = function (attributes,
