搜索功能:从index.html更新不同的视图

标签: html angularjs angular-ui-router xmlhttprequest

我在Laravel中制作了一个REST api,我使用AngularJS作为Frontend。在我的index.html中,我有一个导航栏,在所有视图中都可见。在我的导航栏上,我将实现一个输入字段,该字段应该用于搜索,具体取决于哪个视图处于活动状态。在我的导航栏上,我有4个选项卡,它们将导航到一个视图并从我的api中获取数据。

每个标签都有一个包含CRUD功能的控制器。所以我的问题是如何通过提交搜索表单来获取可见的视图数据。

这是我的app.js,我定义了所有状态,并为我的index.html配备了一个控制器。

    var app = angular.module('myApp', ['ui.router', 'satellizer', 'ngStorage'])
        .config(function($stateProvider, $urlRouterProvider, $authProvider,$provide) {


        $authProvider.loginUrl = 'http://.../authenticate';
        $urlRouterProvider.otherwise('/');

        $stateProvider
            .state('home', {
                url: '/',
                templateUrl: 'view/home.html',
                controller: 'authController'
            }).state('register', {
                url: '/register',
                templateUrl: 'view/register.html',
                controller: 'authController'
            }).state('login', {
                url: '/login',
                templateUrl: 'view/login.html',
                controller: 'authController'
            }).state('companies', {
                url: '/company?page',
                templateUrl: 'view/company/companies.html',
                controller: 'companyController'
            }).state('company', {
                url: '/company/:id',
                templateUrl: 'view/company/company.html',
                controller: 'companyController'
            }).state('users', {
                url: '/user?page',
                templateUrl: 'view/user/users.html',
                controller: 'userController'
            }).state('user', {
                url: '/user/:id',
                templateUrl: 'view/user/user.html',
                controller: 'userController'

                templateUrl: 'view/offerpost/offerposts.html',
                controller: 'offerpostController'

您可以使用事件轻松完成此操作。在您的搜索控制器中,您可以在范围内广播一个事件(我将在此示例中使用$rootScope):

function search() {
  $rootScope.$broadcast('search-initiated', {searchText: $scope.searchText});
}

然后在您的其他每个控制器中,您都可以收听此事件:

$rootScope.$on('search-initiated', function(event, args) {
  // do something with the search text
  var searchText = args.searchText;
});
