Then ((response) = { Console.log (' execution succeeded ');}, (response) = { Console.log (' Execution error ');});Vue-resource supports the Promise API while supporting the current Firefox, Chrome, Safari, Opera and ie9+ browsers that are incompatible with browser compatibility IE8, after all, the Vue i

Binding component event emit:function// component Outgoing eventDestruction of componentsComponent destruction is part of the component life cycle, and when component functionality becomes complex, the correct and reasonable destruction of components becomes particularly important. The destruction of components usually takes into account the following aspects: Unbind internal events within a component Destruction of component Dom Destruction of components ' internal properties

Because currently our hosting environment is not able to run typescript and ECMASCRIPT6 directly, both require compiler compilati

4. For your project, submit the following data/reasonsTeam members and divisionperson in charge : Hoath Tong member : Zhanyang, Yu Qin, Maxiao Day (Me), Zhang Sirie What is the history of innovation in this field? At present, innovation is naturally the NODEJS system, with the help of CHROMEV8 engine rapid development, at the same time produced a large number of front-end framework, RECET,ANGUALRJS and so on. Is your project a pioneer in this field, or are you walking behind the others?

Although each person learns to develop the process will be different, however, the systematic learning method is essential for each learner. For beginners, you should always learn from experienced game developers and learn the skills of game development through their live and video. The more you learn from these experts, the faster you can become a good developer.The proceed () method can be used to invoke the corresponding method of the target object to achieve full control of the target Method

Wijmo UI controls support angular 2Since the 1.x era of angular, WIJMO has supported angular. Recently, we are working with the angular team to support angular 2. Interestingly, support for ANGUALR 2 is even easier. Our source code is written in Typescript, and we can easily extend our control classes to easily create angular 2 components.WIJMO provides angular 2 components for each UI control. All angular 2 components provide full declarative markup. We have provided support for two-way binding

in Angular2, components are the main way we build and specify the elements and logic on the page. and we usually load it in a tag that contains a few conditions that make it load dynamically tagged. But there are cases where we don't know the DOM structure at compile time. in this case, we have to add components to the needs of any location, so we use dynamiccomponentloader dynamically loaded components. in this case, we will be able to instantiate

Angular, a singleton object can be generated by factory and injected into modules A and B that require communication.B. Event-basedThere are two different ways of doing this.The first is the use of the parent controller. Triggers ($emit) an event to the parent controller in the child controller, then listens ($on) the event in the parent controller, and then broadcasts ($BROADCAST) to the child controller, so that the parameters carried by the event are The data is passed through the parent con

announcement released in March this year, will be built on TypeScript, meaning that, if you are working on Angular and want to use Angular2 in the future, this plug-in is essential. Based on Microsoft's support, this plug-in includes Code Completion, correct syntax highlighting, code formatting, and extended navigation functions to TypeScript projects. It also comes with a build system that allows you to compile TypeScript files as JavaScript. To acc

However, familiarity with common browser compatibility issues such as IE7,IE8 compatibility, compatibility of new features in HTML5, etc. is also required.　　5.

TypeScript filesWhile your could continue to compile TypeScript and the TypeScript compiler, the idea is to move everything into webpack. There is several loaders that handle TypeScript files and is generally straightforward to configure. A Popular TypeScript Loader in the Angular community now appears to be awesome-typescript-loader.Move External component HTML templates and stylesheets inlineThis is angular-specific. When you have the components with external templates and/or stylesheets, Ang

way, to come a wave of challenges. So, began the development of their own cordova+ionic3+angular4+typescript route. Now, our app mood development is on the line, and the problem is almost no, the speed is very good, the user experience is also very good. I also have some research on IONIC3, here to share with you.First of all, we should consider carefully before choosing this technology stack. Because Ionic3 and Ionic2 basically special like, but the difference is still there. ANGULAR4 and

avoid freezing the UI thread if the amount of time it takes to process the data is significant.5) Background Data analysisAngular1 is the most popular complaint is its dirty check mechanism, when the scope of data too much can seriously affect performance. And Angular2 is using Webworker to move heavy computational work into the worker thread, so that the interface thread is unaffected.Vi. principle Flow 1, classificationTwo types of worker threads a

Performance Both of these frameworks are very fast in terms of performance. But if you look at a third party reference, you can conclude that Vue 2 is faster than ANGULAR2. In terms of size, although angular 2 uses tree-shaking technology and compilation techniques, the code size can be reduced. Even though the compiler and the full functionality Vue2 (23KB) are much smaller than the angular 2 (50kb). Note, however, that the size reduction of the
