Prototype mode each function (not exactly a class, an object.) has a prototype property, which is a pointer to an object. Using the prototype object'sBenefitsIs that you can have all object instances share the properties and methods that it contains. 1.

functions: if you do not want to learn, it is to waste your youth. My framework is designed to classify all functions using object-oriented thinking. For example, a function related to an array: makearray, as a member of the array class: array. Create (["AAA", "BBB"]); creates an array. For an object-oriented JavaScript framework, you must solve the following problems: Module mechanism-you must

This case to achieve the following effect, specific to the Sina Weibo website micro-blog release boxAchieve the following effectsEffect 1: When the cursor moves into the text box, the text above the text box changes to show the remaining number of words that can be entered, and when the cursor moves out of the text box and there is no input in the text box, the original default text is restoredEffect 2: Text input, text box prompts the remaining text number, the remaining text word count with th

This article mainly introduces the access method of JavaScript class attributes. If you need it, you can refer to the access method of JavaScript class attributes. The Code is as follows: Var fish = {Head: 1,Tail: 1,Feature :{Speak: false,Swim: true}} First, the vertex OPERATOR: The Code is as follows: Console.

I. constructor Method Step 1 select the class name, that is, the name of the constructor.

The function is assembled by analyzing the document. cookie string. Review the operations on cookies in javascript: You can use document. cookie = "userId = 111"; to add a cookie. The full version can be used:Document. cookie = "userId = 111; domain = .google.com; path = \; secure = secure; expire =" + date. toGMTString (); You can set the cookie expiration time, domain name, and path. You only need to delete it before setting the expire time to th

Qiu Javascript CodeHighlight class, highlights/highlightengine v1.2 Note:Previously I used js to write a syntax highlighting tool, but there is no way to customize parameters, and the matching is not very rigorous...Therefore, I have long thought about rewriting one. However, due to time problems, I have never started it... The current plan is:CSS implementation with V1.0V1.1 implement JavascriptV

The more things that JavaScript can do, with the problem is the increase in the number of JS code, in the face of the code, I chose The imitation of the class instantiation of the constructor in the form of automatic start, all the JS code, in a registered format, class.

The class property of the object (class attribute) is a string that represents the type information of the object. Both ECMASCRIPT3 and ECMAScript5 do not provide a way to set this property, and there is only one indirect way to query it. The default ToString () Method (inherited from Object.prototype) returns a string in the following format:[Object class]Such a

. element. query (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 obje

I knew long ago that I could convert arguments to an array: [].slice.call (arguments), because Arguments is a class array object, so you can use it. But I never knew what it was called Class array objects (Array-like objects) Today to see effective JavaScript has a section is devoted to this, feeling really too drag. First look at some of the sample code I wro

this point, Ext has pushed some of the commonly used functions under the Ext object, such as Ext.Element.fly into Ext.fly,ext.domquery.select into Ext.query, and so on, but in terms of overall code, it's a disadvantage compared to jquery. Kissy combines the modular structure of ext, at the same time, it also introduces the problem that ext function access path is too long, because there are such problems in the With statement in JavaScript, and the
