underscore cdn

One, double underlineIf you want the internal properties to be inaccessible externally, you can add two underscores to the name of the property, and __ in Python, the variable name of the instance __ becomes a private variable (private), which can only be accessed internally and cannot be accessed externally.is an instance variable that starts with a double underscore not necessarily externally accessible? Actually, it's not. cannot be accessed direct

In php, what are the special meanings of variables and functions whose names start with an underscore? This is often seen in other people's frameworks, but what are the advantages of doing so?

Website: http://web.jobbole.com/83872/Underscore source version 1.8.2CauseMany people recommend to me to study JS, you can look at some third-party JS class library source code, and the best source of interpretation is also the shortest is underscore, it is also my usual favorite of a library, because it cost-effective: small size, strong ability. Open a look, only 1000 lines, try to read a bit, it is reall

Python core style: Avoid using underscores as the start of variable names.Because underscores have special meanings for the interpreter and are symbols used by built-in identifiers, we recommend that programmers avoid using underscores as the starting point for variable names. In general, variable name _xxx is considered " private "and cannot be used outside of a module or class. When a variable is private, it is good practice to use _xxx to represent variables. Because the variable name __xxx_

Name mangling (also called name Decoration name decoration). In many modern programming languages, this technique is used to solve problems that require unique names, such as naming conflicts/overloads.In Python, a class variable that starts with a double underscore uses the name mangling technique, which automatically adds the class name prefix.What's the use? You can prevent accidental modification to a subclass or outside of a class. Although a var

It's easy to underline characters in Word, but it's not easy to add an underscore. At some point we really need to underline the specified characters, such as the mathematical notation for the average in the math document, or a dash bar on the specified variable. So what are we going to do at this moment? Here are a few small tricks that might help you. Take Word 2007 for example. First, draw the line on the character Perhaps this trick is the least

The underscore "_" is a recognized CSS identifier in the css2.1 specification. The browser ignores unknown CSS attributes. Msie5 + (Windows) ignores the "_" before the CSS attribute name. Therefore, the CSS analysis is, for example, _ color: Red. Homepage, which is correct, is allowed for the css2.1 specification (even for software verification, only the earlier version of css2.0 is supported, saying it is a bug: they are wrong, but it is correct )

Good busy recently, various projects are urgently on-line. CSS adjust the dizzy brain swell, no longer have time to ponder my cute JS goblin.But in the busy schedule still want to express the thanks to Underscore.js, small and light to achieve my needs. Specifically say the situation, the meeting of the Appointment interface,I was bombast with the backstage eldest brother patted chest said, you give me a piece of JSON, I also you a front end (intestines already regret blue)So the backstage of th

The underscore encapsulates common JavaScript Object manipulation methods for improved development efficiency.Between the useless he wrote before, and that was quite sour.such as cyclic processing:for (var i=0;i) { //TODO }With his_.each (data,function(item) { //TODO})To delete a piece of datadata = _.reject (data,function(item) { return item.id = ID to delete}) Still have many, need oneself to experience, use all know very hignAttac

First of all, in order to attack the CDN, we must understand how the CDN works, here we will briefly introduce the CDN working model.The full name of the CDN is the Content Delivery network, which forwards the normal traffic through the accelerated node servers throughout the network to ward off malicious traffic to th

source server.The high-speed cache server is a professional function server highly integrated with software and hardware. It is mainly used for high-speed cache acceleration services and is generally deployed on the network edge. Different acceleration objects are divided into client acceleration and server acceleration. The client acceleration cache is deployed at the network exit and the frequently accessed content is cached locally to increase the response speed and save bandwidth. Server ac

Today I read a book and wrote several functional methods for underscore. 1 Functions in underscore

Jquery $ ("#foo"). Bind ("click", Function () {Alert ("User clicked on ' foo.");});On aliases Backbone var object = {};_.extend (object, backbone.events);Object.on ("Alert", Function (msg) {Alert ("triggered" + msg);});Object.trigger ("Alert", "an event");Object gets the ability to bind and trigger custom name events after extend Backbone.events.On aliases Underscore Bind_.bind (function, object, *arguments)var func =

;func (); Wenyi So, how do you implement the Bind and Bindall functions? function bind (obj, func) {return function () {return func.apply (obj, Array.prototype.slice.call (arguments)); };} function Bindall (obj) {var funcs = Array.prototype.slice.call (arguments, 1); for (var i = 0; i Bind is implemented by using the Apply method The implementation of Bindall is to use bind to reassign all methods Finally, attach a practical use to the complete example :function person (na

The generic JavaScript framework is implemented by injecting its own properties into the Global object window. For example, jquery adds a "$" object to the window, and underscore adds an "_" object to the Window object. What if these global variables already exist before the framework is loaded?Obviously $ is occupied by the jquery framework, and the value of the $ variable that we defined previously is overwritten. If you want to use the jquery frame
