angular - angular4中sidenav产品的过滤管

问题描述

我必须在angular4中为sidenavbar使用过滤管。我有侧边栏菜单列表，如女性服装网站的颜色、合身类型、袖长和尺码，当我点击特定列表（如（s 或 m）尺寸的黑色颜色时，它应该在面板中显示我点击的内容

app.component.html`

<div class="col-md-6" id="sidebar">
  <ul class="nav">
   <li class="nav-item">
     <a class="nav-link" routerlink="#submenu" data-toggle="collapse" (click)="toggle1()" data-target="#submenu">Color <mat-icon class="pull-right" >{{icon1 ? 'remove' : 'add' }}</mat-icon></a>
     <div class="collapse" id="submenu" aria-expanded="false">
        <ul class="nav" *ngFor="let colour of colours ">

解决方案

只需将您选择的值与一些变量绑定并将其显示到视图部分，如下所示 -

export class AppComponent implements OnInit {
constructor(private dataservice:DataserviceService,private global: AppGlobals){}
...
filterSelected: any;
ngOnInit() {
  ...
}
Event(colour) {
  console.log(colour);
  this.filterSelected = colour;
}
}

在查看部分 -

{{filterSelected}}
