api development best practices

In web development, because differences between browsers are implemented differently, some sniffing work is unavoidable, such as the fact that we need to be able to use the universal event binding function in each browser addevent//General Wording//Cons: Every time he is called, it executes the IF condition,varAddevent =function(Elem, type, handler) {if(window.addeventlister) {returnElem.addeventlistener (type, Handler,false); } if(window.attacheve

Note 3 of mobile Web Front-end efficient development practices-code check task, During project development, the unified code style is very important for project collaboration and maintainability. Therefore, some plug-ins can be used to check the code style. The source files in this example include Sass files and JavaScript files that use the ECMAScript 6 specific

object in an interface, can execute different objects method, equal to the director said a boot, the rest of the people can do their own thing.Here we assume that the object has an Execute method, if the object does not have a common method, it can also add one to the object, if the object is created by new way on the prototype chain, if not through new, directly add1 //The New Way2Menubar=NewMenubar ();3Menubar.prototype.execute=function(){4 This.

the Addevent function is entered:1 varAddevent =function(Elem, type, handler) {2 if(window.addeventlistener) {3Addevent =function(Elem, type, handler) {//the difference between this and the previous scenario is that it rewrites itself.4Elem.addeventlistener (type, Handler,false );5 }6}Else if(window.attachevent) {7Addevent =function(Elem, type, handler) {8Elem.attachevent (' on ' +type, handler);9 }Ten } OneAddevent (Elem, type, handler);//This will only be performed the

the adorner mode is intended to add functionality to the Object. The decorator pattern often forms a long decorative chain, while the adapter pattern is usually packaged only once. The proxy mode is to control access to objects and is usually wrapped only once. The function of the appearance mode is similar to the adapter, Some people regard the appearance pattern as the adapter of a set of objects, but the most notable feature of the appearance mode is the definition of a new interface.

Continuous construction practices in Agile development: published in STPS 6th, in the article fly into agile development with agile testing, Glenn Jones shared with us the practice of continuous building in their agile projects: (1) Whenever a developer signs in code, no matter how small the changes are, continuous building will be performed. If a code change is

One of the representatives who used NoSQL in the project years ago, MongoDB, summed up some experiences on Weibo. I would like to share with you here.Refreshing use of MongoDB in developmentMongoDB is a # NoSQL # database suitable for PHP development. It supports high concurrency and schema-free (free structure) features, making PHP development more flexible and efficient. Let's try it all!In many cases, it

Android project development practices: Using Fragment and FragmentTabHost to build the bottom menu (1) Learning is practical. Only by integrating what you have learned into our development, and using it with ease can you truly grasp it. However, it is not easy to use technology overnight. Instead, you need to constantly consolidate your knowledge system and a la

IOS development practices in JSON The data returned by the server to the client is generally in JSON or XML format (except for file downloads). The comparison between JSON and XML is not described here. In general, XML files are huge and the file format is complex. parsing requires a lot of resources and time, and transmission occupies the bandwidth. JSON data format is relatively simple, easy to read and w

[Original] efficient CSS development practices: CSS 3, LESS, SASS, Bootstrap, Foundation, sassbootstrap The shadow effect is usually used to express the feeling that the light is projected on an object. If you want to create a 5.19 text shadow effect, you can use the linear gradient of the background to build it. Figure 5.19 shows the effect of similar Beam Irradiation on text, which highlights the te

In iOS development, MD5 or other hashes are often used to improve the security of your application. The most common operation is to MD5 the password and then transfer it. Of course, there are a lot of ready-made implementations, the blog is to implement the simplest and most commonly used encapsulation MD5 method, making it very convenient to call.(1) realize a category called Crypto, inherit from NSString. Since we are all nsstring MD5, it is conveni

class.PackagingThe purpose of encapsulation is to hide information, encapsulation should be considered "any form of encapsulation", that is, encapsulation is not only hidden data, but also the hidden implementation details, design details and types of hidden objects.Prototype modeIn JavaScript, each object is cloned from the Object.prototype object, so that we can only get a single inheritance relationship, that is, each object inherits from the Object.prototype object, and the object system is

HTML5 audio practices, Web music player development Today we are developing a webpage music player based on HTML5 audio. In the new HTML5 features, audio and video are our new elements of interest. We can finally develop audio and video players from Flash. For a new HTML element, it is nothing more than attributes, events, methods, etc. Please Google for the specific attributes, events, and methods of audio

ArcGIS secondary development practices-Traverse tools in ToolBox !, Arcgistoolbox In AO, the basic process for opening file A is: 1. Create A WorkspaceFactory corresponding to "file; 2. Use WorkspaceFactory to create the Workspace of "file A". The Workspace can be the folder where the file is located (for example, the Workspace of the ToolBox to be created later in this article ), it can also be a spatial d
