Question

我想迭代结果而不是创建foreach循环我使用each()方法：

$collection = Comment::all();

$comment =  $collection->each(function ($comment){
    dd($comment->comment);
});

当我dd()时，我得到了：

＆＃34;帽子; “所以我应该这么想。＆＃34;

但是当我转到视图时：

 return view('welcome')->with('comment',$comment);

我得到了

[{"id":1,"post_id":5,"comment":"Hatter; 'so I should think.","created_at":"2018-04-05 15:23:20","updated_at":"2018-04-05 15:23:20"},

{"id":2,"post_id":5,"comment":"Alice gently remarked;.","created_at":"2018-04-05 15:23:20","updated_at":"2018-04-05 15:23:20"},

依旧......

这是观点：

{{$comment}}

我想迭代整个集合并将数据放入$comment，然后在视图中显示它。

Answer 1

这很简单。然后在属性名称

之后迭代

import { Component, OnInit } from '@angular/core';
import {HttpClient} from '@angular/common/http';
import {Router} from '@angular/router';
import swal from 'sweetalert2';
import {UserService} from '../user.service';

@Component({
  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {
 datos: any;
 matricula: any;
 contrasena: any;

  constructor(private http: HttpClient, private router: Router, private user: UserService) {
  }

  ngOnInit() {
    if (this.user.getUserLoggedIn() === true) {
      this.router.navigate(['/productos']);
    } else {
    }
  }

  getCredentials() {
    this.http.get('http://localhost/cafeteria/login/validar.php').subscribe((data: any) => {
      this.datos = data;
      this.validar();
    });
  }
  validar() {
    if (this.datos[0].matricula === this.matricula) {
      if (this.datos[0].contrasena === this.contrasena) {
         this.user.setUserLoggedIn();
         this.router.navigate(['/productos']);
     switch (this.datos[0].idrol) {
       case '1':
         this.router.navigate(['/productos']);
         break;
       case '2':
         this.router.navigate(['/cPanel']);
         break;
       case '3':
         this.router.navigate(['/cPanel']);
         break;
     }
      }
    } else {
      swal('Datos Incorrectos');
    }
  }
}

如何使用每个方法将结果放入视图中
