如何在不单击ng-class的情况下在ng-click上将ng-style动态应用于所选项目

Question

How to apply ng-style on ng-click dynamically without using ng-class in angular? something like changing color for selected active menu only. something like this DEMO but with ng-style. Below is my code which is toggle function. Can anyone solve this by changing the code or use your own example to change color or font-size for active item when clicked and rest of the items to default state.

<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;
}
})

Try like this.

 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 } });

Can you try using $index as below example with plunker below,

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