选择路由器链接时关闭 md-sidenav [英] Closing md-sidenav when router link is selected

问题描述

我正在做一个有角度的项目，我已经实现了有角度的材料组件，比如侧导航.side-nav 有 ul li 元素，其中链接是嵌套的并且是路由器链接而不是 href.我的问题是，当我选择一个链接转到另一个视图时，我想调用侧导航来切换和关闭.因为它总是保持打开状态

I am working on an angular project, I've implemented angular material components like the side-nav. The side-nav has ul li elements, where the links are nested and are router links not href. my question when I select a link to go to another view, I want to make a call to side nav to toggle and close. cause it always remains open

推荐答案

选项 1:

您可以订阅 Router 事件并在路由器事件发生时关闭 sidenav.

You can subscribe to Router events and close sidenav whenever router event takes place.

代码:

需要这些导入:

import { Component,ViewChild, OnInit, } from '@angular/core';
import { Router, RouterModule } from '@angular/router';
import { MdSidenav, MdSidenavModule } from '@angular/material';

在组件类中:

@ViewChild(MdSidenav) sidenav: MdSidenav;

  title = 'Tour of Heroes';

  constructor(private appService: AppService, 
              private _router: Router){
  }

  ngOnInit() {
    this._router.events.subscribe(() => {
      this.sidenav.close();
    });
}

演示

选项 2:

为每个 li 添加一个 click 事件以在点击时关闭 sidenav.

Add a click event to each li to close sidenav on click.

html:

<ul class="sidenav">
  <li class="sidenav__list">
    <a class="sidenav__list__link " (click)="sidenav.close()" >about</a>
  </li>
</ul>
