because [Object Name. attribute name] If you modify the attribute, [Object Name. attribute name] will not be in the same way as [class name. prototype. attribute names] have the same value, which may cause misunderstanding. There

It is relatively simple to define and use objects in JavaScript, and you can define and initialize an object using {}.This definition of the object is an instance of the object class, which can dynamically add properties and methods during execution, which is very flexible. Let's look at an example:var obj = {property: "This is a parameter", Method:function () {return "This is a function, method is the func

This article illustrates a simple right-click menu class for JavaScript implementations. Share to everyone for your reference. Specifically as follows: This is your own write a right button menu class, shielding off the IE inherent right button menu, a total of four parameters: the first is to display the ID of the div of the right menu The second is the right

(selector). At this point, Ext has pushed some common functions to the Ext object, such as Ext. element. fly to Ext. fly, Ext. domQuery. select to Ext. query, but in terms of the total amount of code, it is inferior to jQuery.KISSY combines the modular structure of Ext and introduces the problem that the function access path of Ext is too long, because the with statement in Javascript has such a problem, using aliases to replace objects with deeper l

The following code defines classes using javascript: Specify the class name and constructor. The first letter of the Class Name (constructor name) is uppercase:Copy codeThe Code is as follows: function YourClass (){} The "this

Most classes in javascript are represented by function functions, and most of them are defined in json format later. Classes in javascript are represented by function functions, as follows: The Code is as follows: Function Student (){// Define the field in the Student class and grant the initial value. However, the access permission for this field is public.Th

the parent class's variable can be used directly in the subclass as long as it is in the Func body. However, instantiation within subclasses is not surefire plan, so let's look at/*---------------------------------------------------------------------------*/varParent =function(name,age) { This. Name =name; This. Age =Age ;} Parent.prototype={run:function() {ale

(The following questions are only for JavaScript, please note that if you have a problem with the statement, please laugh over the line) 1, what is static class/Pseudo static class 2. What is the syntax for writing static classes in Javsscript? (including arrays, constants, whatever, want to be complete) 3. Give a simple example of your explanation The key is the

The example in this article describes a method for JavaScript implementations like GetClass () in Java to get object class names. Share to everyone for your reference. Specifically as follows: There is no function in JavaScript to return a particular type name such as an object Console.log (obj);Get is [object Htmlta
