只在被点击的元素上应用 ng-class

问题描述

我只想在被点击的 button/element 上应用 ng-class，我该怎么做?

JS 文件:

var classApp = angular.module('classApp', []);classApp.controller('classCtrl', function ($scope) {$scope.isActive = false;$scope.activeButton = function() {$scope.isActive = !$scope.isActive;}});

HTML 文件:

<button class="button" ng-class="{'active': isActive}" ng-click="activeButton()" type="button">点击我切换类</button><button class="button" ng-class="{'active': isActive}" ng-click="activeButton()" type="button">点击我切换类</button>

解决方案

这是一个可能的解决方案:

控制器:

classApp.controller('classCtrl', function ($scope) {$scope.isActive = [假，假];$scope.activeButton = 函数(索引){$scope.isActive[index] = !$scope.isActive[index];}});

还有 html:

<button class="button" ng-class="{'active': isActive[0]}" ng-click="activeButton(0)" type="button">点击我切换类</button><button class="button" ng-class="{'active': isActive[1]}" ng-click="activeButton(1)" type="button">点击我切换类</button>

我的解决方案有效，但 @Shashank Agrawal 解决方案更好更干净.

I want to apply the ng-class only on the button/element that was clicked on, how would I do that?

JS file:

var classApp = angular.module('classApp', []);
classApp.controller('classCtrl', function ($scope) {
    $scope.isActive = false;

    $scope.activeButton = function() {
       $scope.isActive = !$scope.isActive;
    }
});

HTML file:

<div ng-app="classApp" ng-controller="classCtrl">
    <button class="button" ng-class="{'active': isActive}" ng-click="activeButton()" type="button">Click Me to Toggle Class</button>

    <button class="button" ng-class="{'active': isActive}" ng-click="activeButton()" type="button">Click Me to Toggle Class</button>
</div>

解决方案

Here is a possible solution:

The controller:

classApp.controller('classCtrl', function ($scope) {
    $scope.isActive = [false, false];

    $scope.activeButton = function (index) {
        $scope.isActive[index] = !$scope.isActive[index];
    }
});

And the html:

<div ng-app="classApp" ng-controller="classCtrl">
    <button class="button" ng-class="{'active': isActive[0]}" ng-click="activeButton(0)" type="button">Click Me to Toggle Class</button>

    <button class="button" ng-class="{'active': isActive[1]}" ng-click="activeButton(1)" type="button">Click Me to Toggle Class</button>
</div>

EDIT: My solution works but @Shashank Agrawal solution is better and cleaner.
