将CSS应用于活动路由器链接[Angular 2] [英] Apply CSS to active router link [Angular 2]

问题描述

我想将特殊的CSS样式属性应用于活动的路由器链接:

I would like to apply special CSS style properties to active router links:

<a [routerLink]='link'>{{name}}</a>

这是我到目前为止尝试过的(使用默认的router-link-active类):

Here is what I tried so far (Using the default router-link-active class):

.router-link-active {
	color: #000;
	font-weight: bold;
}

这行不通，我真的不明白为什么.

It doesn't work and I really don't understand why.

推荐答案

当前Angular 2具有

Currently Angular 2 has a built in attribute that you can use on any link that is used with [routerLink] it is routerLinkActive so all you need to do is have:

<a [routerLink]='link' routerLinkActive="router-link-active">{{name}}</a>

，然后它将识别出哪个路由是当前活动路由，并应用您的router-link-active类.

and then it will recognize which route is the current active route and apply your router-link-active class.

注意:

对于那些在除a标记以外的其他标记上使用routerLink的用户，(我个人是在按钮上使用它的)routerLinkActive不起作用，但应在下一版路由器上起作用- https://github.com/angular/angular/issues/9755

For those who are using routerLink on tags other than a tags, (personally i am using it on a button) routerLinkActive doesn't work but should work on the next release of the router - https://github.com/angular/angular/issues/9755
