本文主要介绍了AngularJS使用ui-route实现多层嵌套路由的示例,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧,希望能帮助到大家。

一、预期实现效果:

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

 (项目地址:https://github.com/liyuan-meng/uiRouter-app)

二、分析题目要求,给出依赖关系,构建项目

1. service:

(1)根据条件查询people数据checkPeople.service,不给出条件则查询所有。

(2)得到路由信息getStateParams.service。

2. components:

(1)hello模块:点击button按钮更改内容。

(2)peolpleList模块:显示people列表,点击people显示people详情。依赖于checkPeople.service模块。

(3)peopleDetail模块:显示people详情,依赖于checkPeople.service模块和getStateParams.service模块。

3. 构建项目:

如图所示:component目录用来保存所有服务模块和业务模块,lib目录保存外部引用(我是用的是angular.js1.5.8和ui-route0.2.18),app.config.js文件用来配置路由,index.html则作为入口文件。

三、实现这个例子

1. 首页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)导入lib中的文件以及所有用到的service和component服务的文件。

(2)ng-app="helloSolarSystem"指明了从helloSolarSystem模块开始解析。

(3)定义视图5643c5c8ec46989a1440c123e54787f3142226fc0f7a4611fbee3f36258ad78a

2. 配置路由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>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)模块名字:helloSolarSystem;

(2)注入'peopleList', 'peopleDetail', 'hello','ui.router'模块。

(3)配置stateProvider服务的视图控制,例如第一个名为helloState的视图控制器:当ui-sref == "helloState"的时候,路由更新为url的值#/helloState,并且5643c5c8ec46989a1440c123e54787f3142226fc0f7a4611fbee3f36258ad78a中显示的内容为5d31ad12eb7f2467fa10436b397d69f6ce2196d7bcfa28427152ee3efb4b3e34组件解析出的内容。

(4)嵌套路由的实现:名为peopleState的视图控制器是父路由。名为peopleState.details的视图控制器是子路由。这是一种相对路由方式,父路由将匹配.../index.html#/peopleState/,子路由将匹配.../index.html#/peopleState/detail/x(x是/detail/:id中的id的值)。如果改成绝对路由的形式,只需要写成url:'^/detail/:id',这时子路由将匹配.../index.html#/detail/x(x是/detail/:id中的id的值)。

4. 实现checkPeople.service(根据条件查找people)

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)在getData这个函数中,我们想要返回一个保存people信息的数组,但是由于使用$http().then()服务的时候,这是一个异步请求,我们并不知道请求什么时候结束,所以世界返回people数组是有问题的。我们注意到,$http().then()是一个Promise对象,所以我们可以想到直接将这个对象返回,这样在就可以使用"函数的结果.then(function(data))"来得到异步请求拿来的数据data。

3. 实现getStateParams.service(获取路由信息)

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)这里的getParams函数返回的是路由信息的最后一个数据,也就是people的id,这个service有些特殊,不够通用,可能还需要优化一下会更加合理。不过并不影响我们的需求。

4. 实现hello模块

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. 实现peolpeList模块:

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)这里的5643c5c8ec46989a1440c123e54787f3142226fc0f7a4611fbee3f36258ad78a用来显示peopleList的子组件pepleDetail

peopleList.component.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. 实现peopleDetail模块

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;
        });
      }
    ]
  });
