从AngularJS更改CSS [英] Changing CSS from AngularJS

问题描述

从DOM变化angularjs控制器是不是一个好的做法。在我的应用程序，点击一个链接后，我改变类内部ngView HTML元素。预期的行为是，我有三个div的，并且如果显示与否中间的一个，我改变。我从控制器这样做。我已阅读，这样做的DOM操作应该以指令来完成，但是我的心是不够宽泛，不能找到一个解决方案。请，如果你有一个建议，我会很高兴。

DOM changes from angularjs controllers are not a good practice. In my application, after clicking on a link, I am changing class of an html element inside ngView. the intended behaviour is, that i have three divs, and I am changing if the middle one is shown or not. I am doing this from a controller. I have read, that doing DOM manipulation should be done in a directive, but my mind is not broad enough to find a solution. Please, if you have a suggestion, I will be glad.

推荐答案

使用 NG-类。

例如：

http://jsfiddle.net/rd13/eTTZj/75/

app = angular.module('myApp', []);

app.directive("click", function () {
    return function(scope, element, attrs) {
        element.bind("click", function() {
            scope.boolChangeClass = !scope.boolChangeClass;
            scope.$apply();
        });
    };
});

一些HTML代码：

Some HTML:

<div id="page">
    <div>One</div>
    <div ng-class="{'my-class':boolChangeClass}">Two</div>
    <div>Three</div>
    <button click>Click me</button>
</div>

当您单击该按钮，类中心的div会根据你的范围内设置boolen值更改。

When you click the button, the class of the center div will change depending on the boolen value set within your scope.
