Sample Code for implementing a tree structure (ztree) menu in AngularJS

This article uses the sample code to introduce in detail how AngularJS can be used to implement a tree structure (ztree) menu. In this article, only a few lines of AngularJS code are used, which is very helpful for daily development, if you need it, you can refer to it for reference. Let's take a look at it. Tree Structure

The tree structure has multiple forms and implementation methods. zTree is simple, elegant, and easy to implement. ZTree is a multi-functional "tree plug-in" implemented by jQuery ". Its biggest advantage is its flexible configuration. A simple parent-child structure can be formed as long as the id and pid values are the same. Coupled with free open source, zTree is becoming increasingly popular.

As follows:

First, you need to know what AngularJS's two-way data binding is to better understand the following code. After a long time, you have come up with the following code to implement the left-side menu tree structure.

To implement the above functions, follow these steps:

Add ng-app to the HTML tag to enable AngularJS to manage the entire HTML document.

MyApp is a module created by myself

The label of the entire menu is as follows:

  
 
 
     
      
  
  
 Dashboard
     
      
  
  
Host  
   
 
    
Host
 
    
Group
 
   
 
     
      
  
  
Container
     
      
  
  
Template 
   
 
    
Monitoring
 
    
Installation
 
   
 
     
      
  
  
User 
   
 
    
Modify Materials
 
    
Change Password
 
    
Add User
 
    
Message
 
   
 
     
      
  
  
Configuration
   
 
 

The JS Code is as follows:

// Create the myApp module var myApp = angular. module ('myapp', []) // create a controller named Left-navigationmyApp.controller ('left-navigation', ['$ scope', function ($ scope) {// define a function navFunc and accept a parameter $ scope. navFunc = function (arg) {// make the navAction variable equal to the value arg $ scope passed in by the function. navAction = arg ;};}]);

Summary

The overall idea is to execute a function when you click the first-level navigation and send the name of the first-level navigation to the function. Then, the second-level navigation is displayed when the navAction variable is equal to its upper-level navigation, otherwise, it will be hidden. The above is all about this article.
