Dependency Injection (DI

Angular's website provides methods for data interaction between parent and child components, such as Viewchild, EventemitterBut if you want to synchronize data between siblings, you don't seem to be giving too much information.Sometimes we think that after you modify the data in one component, it is immediately reflected in another component, or you may need to invoke a method from another component, we can use the RXJS.The following source code in Https://github.com/eleven26/

system based on angular development needs to deal with the following situations in terms of authority control: 1, the UI, the user's corresponding role permissions can access which pages can not access which pages; 2, the reason, when the user is ready to jump to a page, if there is no access to the page, redirect to a false hint page; 3, HTTP request, whether the user has access to certain APIs, if not returned 403 If you deal with the above iss

attached to It. In angular if you write code in the linking function it generally the Post-link function (by default). It is kind of a callback that gets called after the linking function have linked the data with the template. Controller: The controller is a place where you put in some directive specific logic.

To understand how AngularJS works, you must first understand how $ apply () and $ digest () work. This article aims to explain what $ apply () and $ digest () are and how to apply them in daily coding. Explore $ apply () and $ digest () AngularJS provides a very cool feature called Two-way
