如何在同一路由器出口上的一个组件与另一个组件之间传递数据

问题描述

app.component.html

我有两个组成部分1)ResetPassword2)LoginComponent在同一路由器出口上.

I have two components1) ResetPassword2) LoginComponenton the same router-outlet.

成功重置密码.我正在重定向到登录组件.如何将数据从ResetPassword传递到LoginComponent?

on successfully resetting the password. I'm redirecting to login component.How do I pass data from ResetPassword to LoginComponent?

我尝试使用订阅方法执行此操作，但这不起作用.

I tried using subscribe method to do this but that is not working.

有人可以帮我解决这个问题吗?

Can someone help me fix this.

LoginService

export class LoginService{

 private messageSource = new BehaviorSubject('');
    currentMessage = this.messageSource.asObservable();

setResetPassword(message: string) {
        this.messageSource.next(message)
    }
}

LoginComponent

OnInit{

this._loginService.currentMessage.subscribe(message => {

    if (message !== undefined && message !== "") {
                this.toastr.info(message);
    }
});

}

ResetComponent

OnInit(){

this._loginService.setResetPassword("Password Changed Successfully");

}

推荐答案

在 LoginService中尝试以下代码.

import { Injectable, EventEmitter} from "@angular/core";

@Injectable()
export class LoginService {

   currentMessage = new EventEmitter();

   setResetPassword(message: string) {
      this.currentMessage.emit(message)
   }
}

并在提交功能中移动 ResetComponent 代码.

And move your ResetComponent code in submit function.

resetPassword() {
   this._loginService.setResetPassword("Password Changed Successfully");
}

谢谢.
