javascript - AngularJS 中的动态路由问题

标签 javascript angularjs routes

我在网站的某个部分中使用动态路由，并使用 ng-repeat 显示项目列表。当有人单击特定项目时，其各自的内容将显示在新 View 上。

这是我的 ng-repeat 代码部分:

<input type="text" placeholder="SEARCH" ng-model="search" />
        <div id="track-list" ng-repeat="track in tracks | filter:search">
        <a ng-href="#/radio/{{$index}}"><h3 class="track-list-title">{{track.title}}</h3></a>
        <p class="track-list-date">{{track.date | date}}</p>
</div>

这是主索引文件:

    <!DOCTYPE html>
<html ng-app="mainApp">
<head lang="en">
    <meta charset="utf-8">
    <title>Playlife Project</title>

这是主应用程序:

  var mainApp = angular.module("mainApp", ['ngRoute', 'ngAnimate', 'plangular']);

/* page routing */

mainApp.config(function($routeProvider) {
    $routeProvider
        .when('/', {
            templateUrl: 'views/home.html',
            controller: 'homeController'
        })
        .when('/podcast', {
            templateUrl: 'views/podcast.html',
            controller: 'podcastController'
        })
        .when('/radio/:id', {
            templateUrl: 'views/radio.html',
            controller: 'radioController'
        })
        .when('/record', {
            templateUrl: 'views/record.html',
            controller: 'recordController'
        })
        .when('/about', {
            templateUrl: 'views/about.html',
            controller: 'aboutController'
        })
        /*.when('/live', {
            templateUrl: 'views/live.html',
            controller: 'liveController'
        })*/
        .when('/contact', {
            templateUrl: 'views/contact.html',
            controller: 'contactController'
        })
        .otherwise({
            redirectTo: '/'
        });
})

/* player */

.config(function(plangularConfigProvider){
    plangularConfigProvider.clientId = 'f39fd2f8db018982adef87c3ecd63e7a';
})

/* home controller */

.controller('homeController', function($scope, $timeout) {
    $scope.pageClass = 'page page-home';

    var INTERVAL = 5000, slides =[{head:"PLAY LIFE PROJECT", btn:'Listen to Playlife Podcast #002', link:'#', src:"./img/slide-1.jpg"},
        {head:"SUBMIT YOUR TRACKS TO GET FEATURED ON PLAY LIFE RECORDS", btn:'Submit your track', link:'#', src:"./img/slide-2.jpg"},

    function setCurrentSlideIndex(index) {
        $scope.currentIndex = index;
    }

    function isCurrentSlideIndex(index) {
        return $scope.currentIndex === index;
    }

    function nextSlide() {
        $scope.currentIndex = ($scope.currentIndex < $scope.slides.length - 1) ? ++$scope.currentIndex : 0;
        $timeout(nextSlide, INTERVAL);
    }

    function loadSlides() {
        $timeout(nextSlide, INTERVAL);
    }

    $scope.slides = slides;
    $scope.currentIndex = 0;
    $scope.setCurrentSlideIndex = setCurrentSlideIndex;
    $scope.isCurrentSlideIndex = isCurrentSlideIndex;

    loadSlides();

})

.controller('podcastController', ['$scope', function($scope) {
    $scope.pageClass = 'page page-podcast';
    $scope.tracks =[
        {title:'Group Therapy 150 with Above & Beyond and Maor Levi', date: new Date(), link:'#'},
        {title:'Group Therapy 151 with Above & Beyond and Martin Garrix', date: new Date(), link:'#'},
        {title:'Group Therapy 152 with Above & Beyond and Grum', date: new Date(), link:'#'},
        {title:'Group Therapy 153 with Above & Beyond and Andrew Bayer', date: new Date(), link:'#'},
        {title:'Group Therapy 154 with Above & Beyond and Ilan Bluestone', date: new Date(), link:'#'},
        {title:'Group Therapy 155 with Above & Beyond and Armin Van Buuren', date: new Date(), link:'#'},
        {title:'Group Therapy 156 with Above & Beyond and Hardwell', date: new Date(), link:'#'}
    ]
}])

.controller('radioController', ['$scope', '$routeParams', function($scope, $routeParams) {
    $scope.pageClass = 'page';
    $scope.track=$scope.tracks[ $routeParams.id]
}])

.controller('recordController', function($scope) {
    $scope.pageClass = 'page page-record';
})

.controller('aboutController', function($scope) {
    $scope.pageClass = 'page-about';
})

/*
mainApp.controller('liveController', function($scope) {
    $scope.pageClass = 'page-live';
});
*/

.controller('contactController', function($scope) {
    $scope.pageClass = 'page page-contact';
});

当我点击这些项目时，它们会正确显示，它们会重定向到这个新 View ，但不会显示标题，我看到的只是 {{track.title}}。

在检查 Google Chrome 的控制台时，我收到此错误:

最佳答案

问题是 $scope.tracks 是在 podcastController 中定义的，而您在 radioController 中访问它，而 radioController 不知道 podcastController。您可以将 radioController 嵌套在 podcastController 中，也可以将 $scope.tracks 的初始化移至 homeController。

尝试移动

  $scope.tracks =[
      {title:'Group Therapy 150 with Above & Beyond and Maor Levi', date: new Date(), link:'#'},
      {title:'Group Therapy 151 with Above & Beyond and Martin Garrix', date: new Date(), link:'#'},
      {title:'Group Therapy 152 with Above & Beyond and Grum', date: new Date(), link:'#'},
      {title:'Group Therapy 153 with Above & Beyond and Andrew Bayer', date: new Date(), link:'#'},
      {title:'Group Therapy 154 with Above & Beyond and Ilan Bluestone', date: new Date(), link:'#'},
      {title:'Group Therapy 155 with Above & Beyond and Armin Van Buuren', date: new Date(), link:'#'},
      {title:'Group Therapy 156 with Above & Beyond and Hardwell', date: new Date(), link:'#'}
  ]

进入 homeController 并更新

<div ng-controller="homeController" class="{{pageClass}}" ng-view ></div>

到

<div ng-controller="homeController" class="{{pageClass}}">
    <div class="{{pageClass}}" ng-view ></div>
</div>
