Question

如何在不使用角度为ng-class的情况下动态地应用ng-style？类似于仅为所选活动菜单更改颜色。像这样的DEMO，但有ng风格。下面是我的代码，它是切换功能。任何人都可以通过更改代码或使用您自己的示例来解决此问题，以便在单击时将活动项目的颜色或字体大小更改，并将其余项目更改为默认状态。

<div ng-style="x.selected && {'color':'white','font-weight':'bold'}"  
    ng-click="select(x)" ng-repeat="x in myData" ></div>


var app = angular.module('anApp', ['angular.filter']);
app.controller('aCtrl', function($scope) {
  $scope.data = [
  {
    "id": 100,
    "value": "2452"
  },
  {
    "id": 100,
    "value": "2458"
  },
  {
    "id": 1,
    "value": "2457"
  },
  {
    "id": 1,
    "value": "2459"
  },
  {
    "id": 4,
    "value": "2460"
  },
  {
    "id": 5,
    "value": "3458"
  }
];

$scope.select = function(x){
  x.selected = !x.selected;
}
})

</div>

试试这样。

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {

  $scope.menuItems = ['Home', 'Contact', 'About', 'Other'];
  $scope.activeMenu = $scope.menuItems[0];

  $scope.setActive = function(menuItem) {
    $scope.activeMenu = menuItem
  }
});

    <div class="account-heading" ng-style="activeMenu === item && {'background' :'red' }">
      <h4 class="account-title">
        <a href="#/Messages" ng-click="setActive(item)"> {{ item }}</a>
      </h4>
    </div>
  </div>
</div>

你可以尝试使用$ index，如下面的plunker，

<div ng-repeat="x in data" ng-click="setSelected($index)" ng-style="$index === selectedId && {'background' :'red' }">
    {{x.value}}
</div>
