This article mainly introduces the example of AngularJS using ui-route to implement multi-layer nested routing. Now I share it with you and give it as a reference.

This article introduces an example of AngularJS using ui-route to implement multi-layer nested routing, and shares it with everyone. The details are as follows:

1. Expected implementation effect:

https://liyuan-meng.github.io/uiRouter-app/index.html

(Project address: https://github.com/liyuan-meng/uiRouter-app)

2. Analyze the question requirements, give dependencies, and build the project

1. service:

(1) Query people data checkPeople according to conditions. service, if no conditions are given, all will be queried.

(2) Get routing information getStateParams.service.

2. components:

(1) hello module: click the button button to change the content.

(2) peopleList module: displays the people list, click people to display people details. Depends on checkPeople.service module.

(3) peopleDetail module: displays people details, relying on the checkPeople.service module and getStateParams.service module.

3. Build the project:

As shown in the figure: the component directory is used to save all service modules and business modules, and the lib directory saves external references (I Angular.js1.5.8 and ui-route0.2.18 are used), the app.config.js file is used to configure routing, and index.html is used as the entry file.

3. Implement this example

1. Home page index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <script src="./lib/angular.js"></script>
  <script src="./lib/angular-ui-route.js"></script>
  <script src="./app.config.js"></script>
  <script src="./components/core/people/checkPeople.service.js"></script>
  <script src="./components/core/people/getStateParams.service.js"></script>
  <script src="./components/hello/hello.component.js"></script>
  <script src="./components/people-list/people-list.component.js"></script>
  <script src="./components/people-detail/people-detail.component.js"></script>
</head>
<body ng-app="helloSolarSystem">
<p>
  <a ui-sref="helloState">Hello</a>
  <a ui-sref="aboutState">About</a>
  <a ui-sref="peopleState">People</a>
</p>

<ui-view></ui-view>

</body>
</html>

(1) Import the files in lib and all used services and component service files.

(2) ng-app="helloSolarSystem" specifies that parsing starts from the helloSolarSystem module.

(3) Define view

2. Configure routing app.config.js

&#39;use strict&#39;;

angular.module("helloSolarSystem", [&#39;peopleList&#39;, &#39;peopleDetail&#39;, &#39;hello&#39;,&#39;ui.router&#39;]).

  config([&#39;$stateProvider&#39;, function ($stateProvider) {

    $stateProvider.state(&#39;helloState&#39;, {
      url: &#39;/helloState&#39;,
      template:&#39;<hello></hello>&#39;

    }).state(&#39;aboutState&#39;, {
      url: &#39;/about&#39;,
      template: &#39;<h4 id="Its-nbsp-the-nbsp-UI-Router-nbsp-Hello-nbsp-Solar-nbsp-System-nbsp-app">Its the UI-Router Hello Solar System app!</h4>&#39;

    }).state(&#39;peopleState&#39;, {
      url: &#39;/peopleList&#39;,
      template:&#39;<people-list></people-list>&#39;

    }).state(&#39;peopleState.details&#39;, {
      url:&#39;/detail/:id&#39;,
      template: &#39;<people-detail></people-detail>&#39;
    })
  }
]);

(1) Module Name: helloSolarSystem;

(2) Inject 'peopleList', 'peopleDetail', 'hello', 'ui.router' modules.

(3) Configure the view control of the stateProvider service, for example, the first view controller named helloState: when ui-sref == "helloState", the route is updated to the value of url #/helloState, And the content displayed in is the content parsed by the component.

(4) Implementation of nested routing: The view controller named peopleState is the parent routing. The view controller named peopleState.details is a child route. This is a relative routing method. The parent route will match.../index.html#/peopleState/, and the child route will match.../index.html#/peopleState/detail/x (x is /detail/:id the value of id in ). If you change it to absolute routing, you only need to write url:'^/detail/:id', then the sub-route will match.../index.html#/detail/x (x is in /detail/:id) id value).

4. Implement checkPeople.service (find people based on conditions)

checkPeople.sercice.js

&#39;use strict&#39;;

//根据条件（参数）查找信息。
angular.module(&#39;people.checkPeople&#39;, [&#39;ui.router&#39;]).
  factory(&#39;CheckPeople&#39;, [&#39;$http&#39;, function ($http) {
    return {
      getData: getData
    };
    function getData(filed) {
      var people;
      var promise = $http({
        method: &#39;GET&#39;,
        url: &#39;./data/people.json&#39;
      }).then(function (response) {
        if (filed) {
          people = response.data.filter(function (value) {
            if (Number(value.id) === Number(filed)) {
              return value;
            }
          })
        } else {
          people = response.data;
        }
        return people;
      });
      return promise;
    }
  }]);

(1) In the getData function, we want to return a An array that saves people information. However, when using the $http().then() service, this is an asynchronous request. We don’t know when the request will end, so there is a problem with the world returning the people array. We noticed that $http().then() is a Promise object, so we can think of returning this object directly, so that we can use "result of function.then(function(data))" to get the asynchronous request The coming data data.

3. Implement getStateParams.service (get routing information)

getStatePatams.service.js

"use strict";

angular.module("getStateParams", [&#39;ui.router&#39;]).
  factory("GetStateParams", ["$location", function ($location) {
    return {
      getParams: getParams
    };
    function getParams() {
      var partUrlArr = $location.url().split("/");
      return partUrlArr[partUrlArr.length-1];
    }
}]);

(1) The getParams function here returns the last one of the routing information Data, that is, people's IDs. This service is somewhat special and not universal enough. It may need to be optimized to make it more reasonable. But it does not affect our needs.

4. Implement the hello module

hello.template.html

<p>
  <p ng-hide="hideFirstContent">hello solar sytem!</p>
  <p ng-hide="!hideFirstContent">whats up solar sytem!</p>
  <button ng-click="ctlButton()">click</button>
</p>

hello.component.js

&#39;use strict&#39;;

angular.module("hello", [])
  .component(&#39;hello&#39;, {
    templateUrl: &#39;./components/hello/hello.template.html&#39;,
    controller: ["$scope", 
      function HelloController($scope) {
        $scope.hideFirstContent = false;
        $scope.ctlButton = function () {
          this.hideFirstContent = !this.hideFirstContent;
        };
      }
    ]
  });

5. Implement the peopleList module:

peopleList.template.html

<p>
  <ul>
    <a ng-repeat="item in people" ui-sref="peopleState.details({id:item.id})">
      <li>{{item.name}}</li>
    </a>
  </ul>
  <ui-view></ui-view>
</p>

(1) The here is used to display the sub-component pepleDetail

peopleList.component of peopleList .js

&#39;use strict&#39;;

angular.module("peopleList", [&#39;people.checkPeople&#39;])
  .component(&#39;peopleList&#39;, {
    templateUrl: &#39;./components/people-list/people-list.template.html&#39;,
    controller: [&#39;CheckPeople&#39;,&#39;$scope&#39;,
      function PeopleListController(CheckPeople, $scope) {
        $scope.people = [];
        CheckPeople.getData().then(function(data){
          $scope.people = data;
        });
      }
    ]
  });

6. Implement the peopleDetail module

peopleDetail.template.html

<ul ng-repeat="item in peopleDetails track by $index">
  <li>名字： {{item.name}}</li>
  <li>介绍： {{item.intro}}</li>
</ul>

peopleDetail.component.js

&#39;use strict&#39;;

angular.module("peopleDetail", [&#39;people.checkPeople&#39;, &#39;getStateParams&#39;])
  .component(&#39;peopleDetail&#39;, {
    templateUrl: &#39;./components/people-detail/people-detail.template.html&#39;,
    controller: [&#39;CheckPeople&#39;, &#39;GetStateParams&#39;, &#39;$scope&#39;,
      function peopleDetailController(CheckPeople, GetStateParams, $scope) {
        $scope.peopleDetails = [];
        CheckPeople.getData(GetStateParams.getParams()).then(function(data){
          $scope.peopleDetails = data;
        });
      }
    ]
  });

The above is what I compiled for everyone Yes, I hope it will be helpful to everyone in the future.

What is 'this' in JavaScript?Mar 04, 2025 am 01:15 AM

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
