提交包含注册和提交的反应性表单，并且不使用服务而是使用路由在Grid中显示数据

Question

我在角度应用程序中有2个组件注册和登录，注册是一种响应形式，登录有kendo网格列。提交后，我必须在不使用服务的情况下将数据从注册表单传递到网格列。数据存储在控制台中，但不显示在kendo网格字段中。

register.component.ts

import { Component, OnInit, Output, EventEmitter } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { Router, ActivatedRoute } from '@angular/router';


@Component({
    selector: 'app-register',
    templateUrl: './register.component.html',
    styleUrls: ['./register.component.css']
})

export class RegisterComponent implements OnInit {
    registerForm: FormGroup;
    submitted = false;
    loading = false;
    data: any;

    constructor(private formBuilder: FormBuilder, public router: Router, public route: ActivatedRoute) { }

    @Output() public found = new EventEmitter<any>();

    ngOnInit(){
        this.registerForm = this.formBuilder.group({
            'Name': ['', Validators.required],
            'MobileNo': ['', Validators.required],
            'DOB': ['', Validators.required],
            'BloodGroup': ['', Validators.required],
            'ECN': ['', Validators.required],
            'Address': ['', Validators.required],
            'PANNo': ['', Validators.required],
            'BAN': ['', Validators.required],
            'BankName': ['', Validators.required],
            'IFSC': ['', Validators.required],
            'email': ['', [Validators.required, Validators.email]],
            'Active': ['',Validators.required]
        });
        }

    get f() { return this.registerForm.controls; }

    onSubmit() {
        console.log(this.registerForm.value);
        let data: any = this.registerForm.value;
        alert('Form Submitted!! View Details?');

        this.router.navigate(['./login'],
            {
                queryParams: { data:(JSON.stringify(data)) }

            })
    }
}

Answer 1

在Angular> = 7.2.0中，您可以在状态下传递数据

this.router.navigate(['/login'], {state: {data: {...}}});

数据将存储在：

history.state.data
