The use of a combination of models and prototypes constructor model, using the object model prototype rewritable literal that is hidden (related to the dynamic nature of the prototype), in the following example:
<! DOCTYPE HTML>
<HTML>
<head>
<title> in combination of model and prototype model constructor - Problems </ title>
<Script type = "text / JavaScript"> // combination of model and prototype model constructor - - constructor model used to define the instance attribute, a prototype model is used to define methods and shared properties. function Student (name, Age, Sex) {
the this .name = name;
the this .age = Age;
the this .sex = Sex;
the this .friends = [ "Kitty", "Court" ];
} // This embodiment Error @ STU1 new new Student = var ( "Lucy", 10, "Girl"); // Student.
sayName: function () {
// Alert (this.name);
// }
// }
// stu1.sayName (); // use object literal rewriting prototype model error
var STU2 = new new Student ( "Bob" ,. 9, "Boy" );
Student.prototype.sayName = function () {
Alert ( the this .name);
};
stu2.sayName ();
</ Script>
</ head>
<body>
</ body>
</ html>
In learning dynamic prototype model, found in the book marked "when using dynamic prototype model, you can not use an object literal rewriting prototype.", I think of the combination is to use the object literal rewriting of the prototype model, so to verify whether there is problems, so write a little experience, to avoid future mistakes.
