我正在尝试呼叫私人登录:LoginComponent
,但是,当我添加私人登录时,我的网站不会加载:LoginComponent
。在我将Login添加到构造函数之前,我的网站加载并运行正常。我究竟做错了什么?我可以不拨打私人登录:LoginComponent
吗?我已在下面附上课程LoginComponent
。
import { Component, OnInit, ViewChild } from '@angular/core'
import { Router } from '@angular/router'
import * as Rx from "rxjs"
import { environment } from "../../../environments/environment"
import {LoginComponent} from "app/components/login/login.component"
import { AuthService } from "../../services/auth/auth.service"
import { LoginService } from "../../services/login/login.service"
import { SageApiService } from "../../services/sage-api/sage-api.service"
import { DataModel } from "../../model/data-model"
// wvj contract
@Component({
selector: 'app-contract-form',
templateUrl: './contract-form.component.html',
styleUrls: ['./contract-form.component.css']
})
export class ContractFormComponent implements OnInit {
@ViewChild('staticModal') staticModal;
dataModel: DataModel = new DataModel()
constructor(
private router: Router,
private authService: AuthService,
private loginService: LoginService,
private sageApi: SageApiService,
private login: LoginComponent
) { }
}
我试着打电话给这个班:
import { Component, OnInit } from '@angular/core';
import {Router} from "@angular/router";
import { LoginService } from "../../services/login/login.service";
import { AuthService } from "../../services/auth/auth.service"
@Component({
selector: 'app-login',
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {
error: string = "";
username: string = "";
password: string = "";
isLoading: boolean = false;
constructor(
private loginService: LoginService,
private authService: AuthService,
private router: Router
) { }
}

组件之间传递的任何数据都可以通过两种方法进行:
Subject
,在另一个组件中创建subscribe
。无法通过构造函数将一个组件注入另一个组件。

您可以使用依赖注入调用另一个组件的任何函数或变量。这是一个例子。
