This article mainly introduces the use of extend in JQuery. The example analyzes extend functions, definitions, and related usage skills. if you need it, you can refer to the example in this article to describe how to use extend in JQuery. Share it with you for your reference. The specific analysis is as follows:

First, the demandThere are several modules in the project that use the DataTable plugin in jquery. When you start development, you use your own configuration, which results in some unified configuration of the table being dispersed across modules. Now want to extract these unified configuration into the public JS, in order to facilitate the modification of the unified configuration (man do things have a degree, not black or white, Shuizhi. Program is the same, all want to write code unified, but
Understanding jquery's $.extend (), $.fn, and $.fn.extend ()jquery has two methods for developing plug-ins, namely:JQuery.fn.extend ();Jquery.extend ();Jquery.fnJquery.fn = Jquery.prototype = {Init:function (selector, context) {//....//...};The original Jquery.fn = Jquery.prototype. It's certainly not strange to prototype.Although JavaScript does not have a clear class concept, it is more convenient to use a class to understand it. jquery is a well-en
$.extend () and $.fn.extend () usage and differences:The $.extend () and $.fn.extend () two functions are often used when making plugins themselves, and they are very similar from appearance to function, but in fact they are very different, so here's a brief description of what the difference is.In JavaScript, although there is no concept of class, but as an object-oriented language, in fact, there is a cla
Ext. Extend plays a major role in extjs and is one of several important functions in extjs. To gain a deeper understanding of extjs, this function must be mastered. There are a lot of source code analysis and introduction to this function on the Internet. The usage of this function is as follows.
Function Base (config ){ This . Name = Config. Name ; This . Age = config. Age; This . Sex = config. Sex ;} Function Base (config ){ This . Identity = co
The GridView is powerful and easy to use. To make it more powerful and easy to use, we can write a control that inherits from the GridView.

There are two types of jQuery plug-in development: Class 1 and Class 2. The following describes jQuery plug-in development in detail:
Class 1
You can understand the class level as an extension of the jquery class. The most obvious example is $. ajax (...), which is equivalent to a static method.
Use the $. extend method when developing the extension method, that is, jQuery. extend (object );

Ip_conntrack adds a stream record mechanism for stateless IP addresses. Where can you store anything related to a stream? In principle, ip_conntrack should be something that can be infinitely expanded, but in fact, the kernel designer or the ip_conntrack designer of Netfilter did not leave any interfaces and mechanisms for user programmers to extend it, you can only use the existing Connection Tracing Mechanism. Although you can use the nf_ct_extend_r
The relationship between use cases should be difficult to understand when drawing a use case diagram. The relationship between use cases can be divided into three types: Include, extend, and generalization.
First, we will introduce generalization, which is easy to understand. The Generalization relation is an inheritance relation. The subcase inherits all the behaviors, links, and communication relationships of the base case, that is to say, subcases

1. The list can contain any data element. The elements in a single list do not need to be of the same type.2. The append () method adds a new element to the end of the list. Only one parameter is accepted.3. The extend () method accepts only one list as a parameter and adds each element of this parameter to the original list.
Append () usage example:
>>> Mylist = [1, 2, 0, 'abc']
>>> Mylist
[1, 2, 0, 'abc']
>>> Mylist. append (4)
>>> Mylis
Using Flot.js to use the Extend method of jqueryAbout the Extend method I'll go through the manual, deepen my understanding, and honestly I don't understand.Extend extends an object with one or more other objects, returning the object being extended.If you do not specify target, the jquery namespace itself is extended, which helps plug-in authors add new methods as jquery. If the first argument is set to Tr
Step 5: Extend the system disk (only for instances where the system disk is greater than 40GB)
The system disk does not have more than 40GB users, please skip this step.
If you select a system disk that is larger than 40GB when you create an instance, or if you replace the system disk, you will find that the disk size is only 40GB after the initial logon instance. You need to expand the system disk manually.
The following examples of Windows Server
Usually, the default value of the Parameter object is given in the function, at which time it is necessary to overwrite the parameters passed into the default parameters by extend, such as:

This.opts = $.extend ({}, Giant.ui.imageshow.defaults, options);

Native js achieves copying objects, extension objects are similar to the extend () method in jquery, jqueryextend
The extend () method of jq can easily implement the extension object method. The syntax is as follows: $. extend (obj1, boj2, obj3 );
What we need to implement now is: Native js implements copying objects and extension objects, similar to the

1. I have been busy studying data visualization (d3.js, three. js) and the laravel framework of php some time ago. I have encountered many things in my life. This is probably a time of confusion.
In retrospect, when I first came out to work, I had a very clear goal and wanted to learn something. What kind of height will be achieved in the future? We need to talk about things with the gods. Alway
JQuery has two ways of encapsulating code $.extend and $.fn.extend, which we also call encapsulation Plug-ins$.extend DEMO // encapsulates function (options) { Span style= "color: #339966;" >//options can also be multiple parameters a, b, c var name= options.name| | "; var words = Options.words | | "; document.write (name + ' say: ' + words); }}) // call options is multiple arguments, $
