First, angular features:1, two-way data binding, the main selling point2. The MVVM model, separating the view and logic3.

Angular implements permission control in the frontend and backend separation mode-Based on RBAC (1) Role-Based Access Control (RBAC) is a common design of permissions. The basic idea is that permissions for system operations are not directly granted to specific users, instead, a role set is created between the user set and the permission set. Each role corresponds to a group of permissions. Once a user is assigned an appropriate role, the user has al

Vue directive this article shares with you how to use vue directive direve VE for your reference. The details are as follows: 1. Register commands Commands can be used only when they are registered like components. one method is global registration: Vue. directive ('dirname', function () {// define command }); The other is local registration: New Vue ({direct

They are placed in the last few sentences of the framework, because there are too many commands. Therefore, you can build an intelligent application without using a line of JavaScript code.

If it is jquery, you need to process it. Function bindjquery () {// bind to jquery

least one instruction defines a controller, then it is a director instance. The controller is shared across all instructions, which allows the command to use the controller as a communication channel.Transcludefn: A linking function that is pre-bound to the correct embedding range.

ANGULARJS directive-binding policy (@, =, ) Introduce the theme: the template in angular's instruction configuration can write code directly using hard-coded, but it can also be dynamically updated according to the variables. Then you need to use those variables, because of the different usage, so you need to set the appropriate binding policy. One, @ Binding policyThe @ binding strategy, which functions as the value of the v

Instruction definition (transfer from http://www.cnblogs.com/huangshikun/p/7060787.html) For instructions, it can be simply understood as a function that runs on a particular DOM element, and the instruction extends the function of the element. For example, Ng-click can allow an element to listen for a click event and execute a ANGULARJS expression when an event is received It is the directive that makes the framework of ANGULARJS pow

A one-time initialization setting can be performed here (when the code is loaded into memory, if bind is bound to execute , such as the setting of the styling style, bind with BIND). update: Called when the component's Vnode is updated, but may occur before its child Vnode update . The value of the instruction may or may not have changed. Summary: General: 1, the operati

I ' ve talked about the timing of directives in AngularJS a few times before. But, it's a rather complicated topic, so I don ' t mind digging a bit deeper. This time, I ' m looking at the timing of Directive controllers vs. directive link functions. As the DOM (Document Object Model) is compiled by AngularJS, the directive controllers and link functions execute a
