1. ModularComponent-based programming is a trend in web development, and ANGULAR2 provides an efficient and simple way to develop components so that program development pays more attention to the implementation of business logic, without caring about how to load components and modules, how to reference and dependency injection implementations, and so on.As shown in the following code, ANGULAR2 provides anno

JQuery makes it easier to manipulate the DOM. Due to its ease of use and scalability, Jquer also quickly swept the world, a variety of plug-ins are also dizzying.I'm sure a lot of people don't go straight from jquery to the front, because it's so easy to use, and most of what we used to do is based on jquery and its plugins. And now Angular2 's component ecology is not perfect, we may want to use jquery when writing angular. This article provides a br

I know Angular2 's idea of using jquery might see a little bit of an odd lot of you, and we all know that ANGULAR2 is responsible for managing everything related to our view components and DOM elements, which sounds like a good idea, and a working corner made with another frame can be easily done.In other words, why would anyone want jquery and ANGULAR2 integrati

A module can contain components, directives, pipelines, and can declare their access rights public so that the components of the external module can access and use them. module is used to organize the application, through the module mechanism external class library can be very convenient to extend t

Debugging js components during development is always troublesome. The most common method is to use alert or debugger to test the js running status. However, both methods have their own limitations. alert may interrupt, sometimes the values of alert may be unreliable, and the values of alert may be incorrect when you use the closure. Debugger is actually quite difficult to use, and only supports ie. Therefore, the most reasonable method is to output the value to be debugged during the running pro

Logback is built on top of three main classes: Logger,appender and layout. These three components work together to enable developers to record messages by message type and level, and to control the output format and output destination of messages during the program's run time.The logger class is part of the Logback-classic module, and the Appender and layout interfaces come from Logback-core. As a multipurp

Due to the rise of Angular2 soon, the relevant plug-ins are still very few, so sometimes have to use some jquery plug-ins to complete the project,So how do you put the jquery plugin in the angular2?
