jquery has two methods for developing plug-ins, namely: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); Adds a method to a jquery object.As an example,[HTML]View PlainCopy

The Extend extension method prototype in jquery is: 1, Extend (dest,src1,src2,src3 ...);It means to src1,src2,src3 ... Merged into Dest, the return value is the merged dest, which shows that the method is modified to dest structure after merging. If you want to get the results of a merge but do not want to modify the structure of the dest, you can use the following:2, Var newsrc=$.
Since it is a class, there is an abstract class, a specific class, and class inheritance. At the same time, the class members can have instance members and static members. Let's take a look at how prototype achieves this.First look at the following code in prototype:Copy codeThe Code is as follows:Var Abstract = new Object ();Object. extend = function (destination, source ){For (property in source ){Destination [property] = source [property];}Return d

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:

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

1. Extend (SRC),
Today, we study the extend of the extension method of jquery.1.extend (Obj,item1,item2,item3 ...);The implication of this code is that all items, such as SRC1,SCR2, are merged into the Obj object, but there is also a problem so that merging modifies the entire structure of obj.2.var result = $.extend ({},item1,item2,item3 ...);This method skillfully uses the

Extend for objects is a common function. For example, javascript does not overload the function, and the parameter type of the function is not defined. Therefore, it is convenient to input an object as a parameter. The default value of the parameter object is usually provided in the function. In this case, the extend is used to overwrite the input parameter to the default parameter, for example:
