Do you know the routing principle of angularjs? Here are the detailed principles of angularjs routing

This article mainly introduces you to the routing principle of angularjs, as well as the steps of angularjs routing. It is not too in-depth, everyone should be able to understand it. . Next, let us take a look at this article

1. Let’s take a look at the introduction of angularjs:

The AngularJS routing mechanism is provided by the ngRoute module, which Allows us to decompose the view into a layout and a template view, and dynamically load the template view into the layout according to the URL change, thereby realizing the page jump function of a single-page application.

2. Look at the url in AngularJS again

The # sign is added to the URL of the single-page WEB application. The # sign represents a location on the web page. Everything on the right is the identifier used to mark the location. The # sign and the following content are called hash fragments in the URL. They will not be sent to the server. The following three URLs request the same address from the server. If you only change the content after the # sign, refreshing will not cause the web page to be reloaded.

3. Now let’s talk about the use of routing:

1. Import files and inject dependencies

Since version 1.2, AngularJS has separated ngRoutes from the core code into an independent module. Therefore, we need to install and inject dependency on ngRoute in the module declaration to use the routing function normally in AngularJS applications. (If you want to know more about angularjs, go to the PHP Chinese website AngularJs Learning Manual column)

<script src="angular-route.min.js"></script>
var app = angular.module("myApp",[&#39;ngRoute&#39;]);

2. Create a layout template

The reason why a layout template is created is to tell AngularJS where the layout should be rendered. Through the ng-view directive, we can accurately specify the rendering position of the template view in the DOM.

<div ng-app="myApp">
    <a ng-href="#/music">音乐</a>
    <a ng-href="#/movie">电影</a>
    <a ng-href="#/novel">小说</a>
    <a ng-href="#/other">其他</a>
    <div ng-view></div>
</div>

3. Create some template views

myMusic.html

<p>这里是音乐界面啦</p>

myMovie.html

<p>这里是电影界面啦</p>

myNovel.html

<p>这里是小说界面啦</p>

home.html

<p>我是首页界面</p>

4. Define the routing table

app.config(['$routeProvider',function($routeProvide) {
    $routeProvide
        .when('/',{templateUrl:"home.html"})
        .when('/music',{templateUrl:"myMusic.html"})
        .when('/movie',{templateUrl:"myMovie.html"})
        .when('/novel',{templateUrl:"myNovel.html"})
        .otherwise({redirectTo:'/'});
}]);
