背景图像未显示在AngularJS中

Background image not showing up in AngularJS

我的自定义背景图像没有显示在AngularJS中。不知道为什么。

当我在控制台中测试$scope.setBackground时，我得到对象{background-image: "url(image.jpg)"}

控制器：

app.controller('backgroundImageCtrl', function($scope, $http) {
    $scope.setBackground = {
        'background-image' : 'url(image.jpg)'
    };
})

HTML:

<script type = "text/ng-template" id="/page.html" ng-controller="backgroundImageCtrl" ng-style="setBackground">
    <div>
    ...
    </div>
</script>


var app = angular.module('myApp', []);
app.controller("myCtrl", function ($scope) {
    $scope.style= {};
    $scope.setBackground = function (date) {
      $scope.style = {
        'background-image': 'url("https://www.gravatar.com/avatar/10821c595d354140ee66f2a04fb11b7c?s=32&d=identicon&r=PG&f=1")'
      }
    };
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="myCtrl">
    <button ng-click="setBackground()">set background</button>
    <div ng-style="style">see the background</div>
  </div>
</div>

@Mosh Feu建议的简单解决方案，只需将ng-controller="backgroundImageCtrl"和ng-style="setBackground"放置在内部div 中

<script type = "text/ng-template" id="/page.html">
    <div ng-controller="backgroundImageCtrl" ng-style="setBackground">
    ...
    </div>
</script>

您应该在使用模板的div中使用setBackground。试试这个。

<div ng-include src="/page.html" ng-style="setBackground"></div>


var mainApp = angular.module("mainApp", ['ngRoute']);
mainApp.config(['$routeProvider', function($routeProvider) {
  $routeProvider.
  when('/addStudent', {
    templateUrl: 'addStudent.htm',
    controller: 'AddStudentController'
  }).
  when('/viewStudents', {
    templateUrl: 'viewStudents.htm',
    controller: 'ViewStudentsController'
  }).
  otherwise({
    redirectTo: '/addStudent'
  });
}]);
mainApp.controller('AddStudentController', function($scope) {
  $scope.message = "This page will be used to display add student form";
  $scope.setBackground = {
    'background-image' : 'url(https://www.gravatar.com/avatar/10821c595d354140ee66f2a04fb11b7c?s=32&d=identicon&r=PG&f=1)'
  };
});
mainApp.controller('ViewStudentsController', function($scope) {
  $scope.message = "This page will be used to display all the students";
  $scope.setBackground = {
    'background-image' : 'url(https://www.gravatar.com/avatar/6755dcaf172d19cb9976bedcc56cfed3?s=48&d=identicon&r=PG&f=1)'
  };
});
<script src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular-route.min.js"></script>
<div ng-app = "mainApp">
  <p><a href = "#addStudent">Add Student</a></p>
  <p><a href = "#viewStudents">View Students</a></p>
  <div ng-view ng-style="setBackground"></div>
  <script type="text/ng-template" id="addStudent.htm">
    <h2> Add Student </h2>
    {{message}}
  </script>
  <script type = "text/ng-template" id="viewStudents.htm">
    <h2> View Students </h2>
    {{message}}
  </script>
</div>
