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=$.
in the plugin must have a ";" (semicolon), otherwise it will be detrimental to the minimization of the code. That's not clear.5, except for the special note, all methods must return the JQuery object, in fact, return this. This is mainly for chained programming, which is everywhere in jquery.6, always use "jQuery" instead of "$" 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

Example 1: Expand jquery itself
Example 2: Extended object
Example 3: shallow copy-references exist in OBJ
Example 4: Deep copy-references exist in OBJ
Example 5: Expand jquery. FN
From the jquery source code, we can see that jquery. Extend and jquery. FN. Extend are actually different references pointing to the same method.
Jquery.

In unity, of course, we extend it.There are two points to keep in mind about extending the class of unity or C # to the following:1. This class must be declared as static, and the extended method must be declared as static2, in use, you can directly call the extens
Project I see a lot of projects where developers implement their own MVC framework, not because they want to do something different from struts, but because they don't realize how to extend struts. Developing your own MVC framework can gain full control, but it also means that you need a lot of resources to implement it (human resources), which is sometimes impossible under tight schedules. Struts is not only a powerful framework, but it is also ext
In the morning to see the "JavaScript Weekly Guide" "Phase III" of the article, which found an article (extending javascript–the right Way), feel good, translated to share with you, this article is not a word for translation, as far as possible to speak in plain language.
Original address: extending Javascript–the right WayThe following is the translationJavaScript already has a lot of powerful methods built into it, but sometimes you need a feature that isn't in the built-in method, so how do
JQ's Extend () method can conveniently implement the extended object method, the syntax is as follows: $.extend (OBJ1,BOJ2,OBJ3);
Now to achieve is: the original JS implementation of replication objects, extended objects, similar to the JQ in the Extend () method, specific examples are as follows:Existing 3 objects literal:
var o1={hello:1,old:555},
O2 =
Recently, when I learned the Python language and saw adding more data to the list by append (), Extend (), the Insert () method was passed around.
Append and extend all need 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
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 in prototype
Code :
Copy code The Code is as follows: var abstract = new object ();
Object. Extend = function (destination, source ){
For (property in source ){
Destination [property] = source [property]

The quality of Python language is not much to say, I would like to mention how to use Boost.python, through the Boost.python can not only transfer Python to C + +, through the Python library, or through C + + to extend Python, The following mainly describes the use of Boost.python to extend the functionality of Python, the first time with Boost.python, Daoteng for half a day to fix:My test environment is li
1.$.extend ({},defaults, options)
This is done to protect the package default parameters. That is, the parameters inside the defaults.
The idea is to make a new empty object ({}) the first parameter of the $.extend, followed by the defaults and the user-passed Parameter object, which has the advantage that all values are merged onto the empty object, protecting the default values within the plug-in.
Extend functions in jQuery
In the jQuery API manual, we can see that extend is actually mounted to jQuery and jQuery. two different methods on fn, although jQuery. extend () and jQuery. fn. extend () is implemented using the same code, but their functions are not the same. Let's take a look at the official API's explan

Prototype (III): object. Extend
The class definition is mentioned above. Prototype distinguishes functions from classes by using a global object class. 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. (For more information, see www.x2design.net)First look at the following
