与routerLink的相对链接/部分路由 [英] Relative links/partial routes with routerLink

问题描述

在我的应用中，某些URL的格式为

In my app some URLs take the form

/department/:dep/employee/:emp/contacts

在边栏中，我显示了所有雇员的列表，每个雇员都有一个[routerLink]，该链接链接到该雇员的联系人

In my sidebar I show a list of all employees, each of which has a [routerLink] which links to that employee's contacts

<ul>
    <li>
        <a [routerLink]="['/department', 1, 'employee', 1, 'contacts']"></a>
    <li>
    <li>
        <a [routerLink]="['/department', 1, 'employee', 2, 'contacts']"></a>
    <li>
    ...
</ul>

但是，通过这种方法，我总是需要提供完整的路径，包括所有参数(例如上例中的dep)，这非常麻烦.有没有办法只提供部分路线，例如

However, with this approach I always need to provide the full path, including all the params (like dep in the above example) which is quite cumbersome. Is there a way to provide just part of the route, such as

<a [routerLink]="['employee', 2, 'contacts']"></a>

(没有department部分，因为我并不真正在乎该观点中的department，我的感觉是这仍然与关注点分离背道而驰)?

(without the department part, because I don't really care about department in that view and my feeling is that this goes against separation of concerns anyway)?

推荐答案

应该可以.前导/使其成为一条绝对路径，没有它(或使用./)，它将成为相对于当前路径的相对路径.您还可以使用../(或../../或更高版本)相对于父级或父级父级进行路由.

That's supposed to work. The leading / makes it an absolute route, without it (or with ./), it becomes a relative route relative to the current route. You can also use ../ (or ../../ or more) to route relative to the parent or parents parent.
