css - Angular2中怎么不通过路由实现多个button的切换效果？

Question

如何不用路由实现点击按钮时，当前按钮背景颜色变成蓝色，其他按钮背景颜色任然是灰色的效果呢？

Answer 1

You should ask and answer your own questions. This effect has been achieved through the ng2 command. For details, please see:

Answer 2

ng-class满足不了吗
    <p ng-class="{true: 'green', false: 'red'}[isA[0]]"></p>
    <p ng-class="{true: 'green', false: 'red'}[isA[1]]"></p>
点击事件去修改isA数组

After reading your blog post, although the principles are the same, I still feel that your approach may be complicated. Post it here for you to take a look :)

The best practice I personally think is the solution that the angular-router module has provided us: the routerLinkActive directive.
