JQuery. extend function usage details, Extends of JQuery: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.1. The extension method prototype of Jquery is:　　　Extend (dest, src1, src2, src3 ...); It means to merge src1, src2, src3... into t

The two methods use the same code, one for the jquery object or the common object merging properties and methods, one for the jquery object, and a few examples for the basic usage: The HTML code is as follows: code as follows: Below write JS inside usage: Merge two Normal objects code as follows: Combine properties for two normal objects var obj1={name: ' Tom ', age:22}; var obj2={name: ' Jack ', height:180}; Console.log ($.

Copy codeThe Code is as follows:$. Extend (true, obj1, obj2) indicates the extended object obj1 in obj2. The first parameter is set to true, which indicates deep replication.Although obj1 does not have the "x" attribute, after expansion, obj1 not only has the "x" attribute, the modification to the "x" attribute in obj2 does not affect the value of the "x" attribute in obj1. This is the so-called "Deep replication. Implementation of light Replication I

Openstack Nova secondary development-Nova-extended service This article mainly describes how to start openstack Nova-extend services. This service is used for secondary extension and development of some requirements of openstack, such as node inspection and dynamic migration (based on Fuse file system implementation, distributed system, such as moosefs), file injection, Nova Service's own repair, instances Io control, instances CPU isolation technolo

in the plugin must have a ";" (semicolon), otherwise it will be detrimental to the minimization of the code. That's not clear.5, except for the special note, all methods must return the JQuery object, in fact, return this. This is mainly for chained programming, which is everywhere in jquery.6, always use "jQuery" instead of "$" in the plugin code. This is not mandatory, for example, I write the closure can write: (function ($)) (jQuery) This format, and then use $ in it, where the $ is actuall

jquery has two methods for developing plug-ins, namely:JQuery.fn.extend ();Jquery.extend ();Although JavaScript does not have a clear class concept, it is more convenient to use a class to understand it.jquery is a well-encapsulated class, such as we use the statement $ ("#btn1") to generate an instance of the jquery class.Jquery.extend (object); Adding a class method to the jquery class can be understood as adding a static method. Such as:jQuery.extend({ min: function(a, b) { return a max: func

In jquery, extend is actually used in many plug-ins.

1. Recognize jQuery extend () and JQuery.fn.extend () In the jquery API manual, theextend method mounts the methods on jquery and Jquery.fn two different objects, but the jquery internal code implements the same, but the functionality is not the same; And look at the official explanation:Jquery.extend(): Merge the contents of the or more objects together into the first object. Merge two or more objects into the first one ); JQuery.fn.extend(): Merge

Preface: The first two days after the festival, mainly to adjust the working status. The project is not very tight either. over the weekend, I would like to sum up some JS and JQuery problems that I encountered a year ago. It mainly introduces the extend method and (function ($) {}) (JQuery) of jQuery, and also involves some related knowledge.1. Differences between substring and substr in JS Previously, the substring method was used in the project, be
