Question

我的打字稿文件中有一个属性

subject.component.ts

subject: string; 
this.subject = "angular";

我要将其传递到HTML文件中的routerlink

subject.component.html

[routerLink]="[subject,'area']"

app.routes.ts

  path: 'angular',
  component: SubjectComponent,
  children: [
    {
      path: 'area',
      component: AreaComponent,
      data: { subject: 'angular' }
    }
  path: 'angular2',
  component: SubjectComponent,
  children: [
    {
      path: 'area',
      component: AreaComponent,
      data: { subject: 'angular2' }
    }

但是我遇到了问题，因为它没有解决。请求的页面未返回。我已重定向到主屏幕

Answer 1

您可以如下设置查询参数和片段：

// subject = 'sss' ; set in your component otherwise it wont be added.

<a [routerLink]="['/user/bob']" [queryParams]="{sub: subject }" fragment="education"></a>

Answer 3

我遇到的问题与我尝试访问的链接的相对路径有关。我所做的更改是添加一个前导斜杠

subject.component.html

[routerLink] =“ ['/'，subject，'area']”

将值从打字稿传递到routerlink
