However, during the writing process, we found that if we want to add a new static method or instance method to the previously written object, we need to modify the original object structure, so we checked the extend method of jquery, sure enough, the extend method supports the half-day of JQ and uses it as an extension for its own objects. Enter the subject below:Assume that there is a next objectCopyCo

This article records is the individual in the use of $.extend encountered a small problem, as well as causal analysis and solutions, very practical, the need for small partners can refer to. I've been working on the mobile side lately, and since I'm familiar with jquery, plus Zepto provides the same API as jquery, I chose Zepto as the development framework. As a result of the mobile-side development, some ES5 new APIs, such as foreach, are also appl

Use the code of extend (inherited by js) in Extjs to copy lt; a simple description of Extjs gt; Note: Copy Books The traditional js implementation inheritance operation is: 1. Define a parent class The Code is as follows: Var BaseClass = function (){//.....};BaseClass. prototype. someMethod = function (){//.....};BaseClass. prototype. overridenMethod = function (){//....} Define two someMethod and overridenMethod functions for BaseClass

As we all know, imported flat guiderails, especially high-precision guiderails in Japan, are self-evident in quality. Good guiderails must also be well handled; otherwise, the service life will be shortened. This involves how NSK linear guide can prolong its service life? Next we will solve the problem for everyone.What kind of processing does NSK linear guide

The Extension Method extend of Jquery is a commonly used method in the process of writing plug-ins. This method has some heavy-load prototypes. Here, let's get to know about it. The Extension Method prototype of Jquery is: Extend (dest, src1, src2, src3 ...);It means to merge src1, src2, src3... into the dest, and the returned value is the merged dest. It can be seen that the structure of the dest is modif

Python language, append (), extend (), and the Insert () method are used to see the addition of more data to the list.Both append and extend require only one parameter and are automatically added to the end of the array, and if you need to add more than one, the array can be nested, but append is the nested array as an object.Extend is to add nested array contents as multiple objects to the original arrayAs

In addition to having system-default monitoring items, SNMP provides a powerful feature to customize monitoring items.The EXEC option in the snmpd.conf configuration file (in the higher version of SNMP, extend instead of exec) provides a custom monitoring feature that can add commands or script execution results to SNMP queries.The format is: extend oid identifier comm

Summary of $.extend () usage. jquery has two methods for developing Plug-ins, respectively: JQuery.fn.extend (object); Jquery.extend (object); Jquery.extend (object); To extend the jquery class itself. Adds a new method to the class.JQuery.fn.extend (object); Add methods to the JQuery object. This should be very well understood. Give an example. OK, so you've seen a little bit of $.

Jquery.extend = JQuery.fn.extend = function () {var options, name, SRC, copy, Copyisarray, clone, target = Arguments[0] || {}, I = 1, length = arguments.length, deep = false; Handle a deep copy situation if (typeof target = = "Boolean") {deep = target; target = Arguments[1] | | {}; Skip the Boolean and the target i = 2; //Handle case when the target is a string or something (possible in deep copy) if (typeof target!== "Object" amp ;!jquery.isfunction (target)) {target = {}; }//

In the process of using jquery, Extend is a commonly used parameter processing function, especially for default values. The extension method prototype for jquery is: var v=$.extend (DEST,SRC1,SRC2,[,SRC3 ...]); The effect is to merge the SRC1,SRC2,SRC3 into the Dest and return the merged dest. But in the process of using, the default value is often cannot be changed, As follows: var defaut={

, but bloggers with code cleanliness are not quite satisfied with the code. It is difficult to read and maintain, while reusability will be extremely poor. So I decided to Bootstrap plug-in way to a BS way write this plug-in. When the author consulted bootstrap ToolTip source code, found that it is a very good extension of plug-ins. ToolTip's display and concealment depend on its internal hoverstate state to control, in represents on the dependency node element, and out represents the removal o

In some html, we often see the use of plug-ins: For example: $ ('# Slides'). slides ({ Preload: true, Container: 'slides _ iner ', SlidesLoaded: function (){ JQuery ('. caption'). fadeIn (800 ); } }); This is the api interface provided by a slides function. It encapsulates a js function and provides some interfaces: preload, container, slidesLoaded, In this way, you only need to input the corresponding value according to the interface instructions to run this function normally. JQuery is a hug

Extend can be said to be one of the most common functions of jQuery, with the exception of several functions of the core, almost all of which use extend for prototyping or static function expansion.
