几个元素切换带班纳克点击 [英] Toggle class with ng-click on several elements

问题描述

我怎样才能切换班的几个要素与NG-点击单独？

How can I toggle classes on several elements individually with ng-click?

在这个问题 http://stackoverflow.com/a/22072110/2169327 切换与点击班做像这样的：

In this question http://stackoverflow.com/a/22072110/2169327 toggling classes with a click was done like this:

CSS：

.red {
    color: red;
}

JS：

$scope.toggle = false;

HTML

<button id="btn" ng-click="toggle = !toggle" ng-class="{'red' : toggle}">Change Class</button>

但是，如果我有几个按钮，每个应可以切换自己的类纳克点击？

But what if I have several buttons that each should toggle its own class with ng-click?

如果我将它设置了这种方式：

If I set it up in this way:

HTML

<button id="btn" ng-click="toggle = !toggle" ng-class="{'red' : toggle}">Change Class</button>
<button id="btn2" ng-click="toggle = !toggle" ng-class="{'red' : toggle}">Change Class</button>

如果我preSS的一个或两个按钮切换获得

Both buttons get toggled if I press one.

我认识的一个解决方法是定义一个自己的NG-单击事件为每个按钮（为Button1 f.ex toggle1，toggle2的按钮2） - 但这是最​​好的办法。

I know a workaround is to define an own ng-click event for each button (f.ex toggle1 for button1, toggle2 for button2) - but is this the best way?

推荐答案

我做了简单的指令来进行测试：

I made simple directive for testing:

module.directive('toggleClass', function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            element.bind('click', function() {
                element.toggleClass(attrs.toggleClass);
            });
        }
    };
});

这样就可以让你需要的任何元素拨动类

so you can make any element toggle class you need

<button id="btn" toggle-class="active">Change Class</button>
<div toggle-class="whatever"></div>
