is a function, and the FN object is from the FN function new, so that the FN object can invoke the properties in Fn.prototype.Because each object has a hidden property--"__proto__", this property references the prototype of the function that created the object. That is: fn.__proto__ = = = Fn.prototypeHere the "__proto__" becomes the "implicit prototype", and the next one continues to decompose.---------------------------------------------------------------------------This article has been updat

One of the refactoring is that the code is basically the same when chatting with both the message and the message received, so I refactor it. As for when to refactor, how to refactor, the novice friends can learn a lot of their own.These two points are usually in the project often encountere

To be honest, this extjs SeriesArticleI am not very popular in the blog field. Maybe there are not many people learning this stuff, but I think there is such a series of articles that are very helpful to Chinese friends! Please support it!In the previous article, the extjs2.0 Learning Series (5) -- Ext. formpanel, we discussed the knowledge of fieldset and form verification. Today we will go deep into the u

DNS Literacy Series 3: Smart DNS (BIND + VIEW) preface: Smart DNS is the function implementation of BIND + VIEW. In China, the first thing we put smart DNS into the market was even (how can we feel unmodest ). I think the introduction of the VIEW function in BIND9.X is not targeted at China, but this function can solve the interconnection problem between network operators in China. This article is based on

use this type to replace the above Code . When the service starts running, the initializeservice method is automatically executed. You can add code for the entity model entity published by the Service and the read permission of the specified client to the initializeservice method. For example, you can indicate that data in a group of entities is read-only, and data in another group of entities is writable. The following exercises describe how to use a WCF Data Service template to create and co

Pure for the gossip and a few friends of the gag, only for easy with a hint of humor, it technology can also be used to ridicule, but also pretty intriguing.At the same time in

This article introduces JavaGC optimization practices. For more information about coders, see. This is the third article in the "GC Expert Series. In the first article, we learned the processing process of several different GC Algorithms in Java garbage collection, the working method of GC, and the difference between the new generation and the old generation. Therefore, you should have understood the five GC types in JDK 7 and their impact on performa

The first two sections of this series have already covered how to configure the Ruby on Rails development environment, and now it's time to get to the point!Part1. Pre-development Preparation The main task of this time is to develop the first rails program. In particular, this time I chose a (PAAs development platform), which is the Cloud 9 platform described in the Rails tutorial, which has automatically made our environment configuration work,

of the introduction, the work requires you to be based on the specific business scenarios for the architecture design.The above is the e-commerce website Architecture case sharing a total of three, from the e-commerce website needs, to the single-machine architecture, gradually evolved into a common, reference to the distributed architecture of the prototype. In addition to functional requirements, there are certain high-performance, high-availability, scalable, scalable and other non-functiona

, which can be used to copy mutable values such as lists or dictionaries, and not just copy references.If the list you want to copy contains a list, use the copy.deepcopy () function instead. The Deepcopy () function copies the list of colleagues inside them.>>>importcopy>>>list=[' A ', ' B ', ' C ']>>>newlist=copy.copy (list ) >>>newlist[1]=100>>>list[' A ', ' B ', ' C ']>>>newlist[' a ', 100, ' C ']>>>list=[1,2,3,[4,5,6,[7,8,9]]]>>>newlist1=copy.copy (list) >>>newlist1[

Back to think MD5, through the above article, you can know, in fact, SHA-1 and MD5 is expatiating, but their respective implementation of different ways, SHA-1 in the number of operations is more compl

The Fibonacci number , also known as the Fibonacci sequence (Italian: Successione di Fibonacci), also known as the Golden Division Series, Fibonacci, Fibonacci, Fisher series, refers to such a series: 0, 1, 1, 2, 3, 5, 8, 13, 21st...... In mathematics, the Fibonacci sequence is defined as the following recursive method
