AngularJS 2错误未定义的索引1 [英] AngularJS 2 Error undefined index1

问题描述

我正在尝试实现一个MeanStack项目，当我尝试单击按钮更新时出现此错误: 错误:请求的路径在索引1处包含未定义的段

I'm trying to achieve a MeanStack Project, when i'm trying to hit the button update i get this error : Error: The requested path contains undefined segment at index 1

有更新服务

 updateLocation(id, data) {
    return new Promise((resolve, reject) => {
        this.http.put('https://exemple.herokuapp.com/api/A/'+id, data)
          .map(res => res.json())
          .subscribe(res => {
            resolve(res);
          }, (err) => {
            reject(err);
          });
    });
  }

html

<form (submit)="onEditSubmit()">

和component.ts

And the component.ts

  onEditSubmit() {
    this.locationService.updateLocation(this.id,this.location).then((result) => {
      let id = result['_id'];
      this.router.navigate(['locations/', id]);
    }, (err) => {
      console.log(err);
    });
  }

推荐答案

将this.router.navigate(['locations/', id]);替换为this.router.navigate(['/locations', id]);
