AngularJS Ng风格

我正在尝试使用ng-style作为div。我尝试了各种各样的东西,并在谷歌和Stackoverflow上检查了它,但我无法让它工作。仅显示testInsideDiv文本。我检查一下我是否对'进行了检查,但是我没有看到它,而且我尝试过很多不同的东西。任何人都能看到问题所在?

以下是代码:

<div ng-style="{'width' : {{deviceWidth}}, 'height' : {{deviceHeight}}, 'background-image':{{imagePath}}, 'background-size' : {{deviceWidth}} {{deviceHeight}}, 'background-repeat':'no-repeat'" ng-click="addOnClick($event)">testInsideDiv
                </div>

在debuger中看起来像这样:

 <div ng-style="{'width' : 569px, 'height' : 300px,
 'background-image':'url('http://scada.voco.si/Portals/0/Scadas/2/28/28.jpg')',
 'background-size' : 569px 300px}, 'background-repeat':'no-repeat'"
 ng-click="addOnClick($event)"
 class="disable-user-behavior">testInsideDiv
                 </div>

你不能使用双括号:

<div ng-style="{'width': deviceWidth, 'height': deviceHeight}">...</div>

主要错误 - 您忘记了ng样式对象的结束大括号

如果您更容易使用camelCase,并且如果您要插入变量,请确保引用它们。但是,您可能不希望插值,但需要绑定,因此通过更改范围变量,样式也会更改:

<div ng-style="{
    width : deviceWidth, 
    height : deviceHeight, 
    backgroundImage: imagePath, 
    backgroundSize: deviceWidth + ' ' + deviceHeight, 
    backgroundRepeat: 'no-repeat'
    }" ng-click="addOnClick($event)">testInsideDiv</div>

请在此处查看:

angular.module('app', [])
  .controller('Ctrl', function($scope) {
    $scope.deviceWidth = '460px';
    $scope.deviceHeight = '276px';
    $scope.imagePath = 'url(http://cdn2.business2community.com/wp-content/uploads/2014/12/Super-Mario-no-longer-the-007.jpg)';
  
    // changing scope properties will make the style change
    // because the values are not interpolated
    // as in your original code
    $scope.shrink = function() {
      $scope.deviceWidth = '230px';
      $scope.deviceHeight = '138px';
    }
  })
