如何将一个组件之间的数据传递到同一路由器插座上的另一个组件 [英] how to pass data between one component to another which is on same router-outlet

问题描述

app.component.html

我有两个组件1) 重置密码2) 登录组件在同一个路由器插座上.

I have two components 1) ResetPassword 2) LoginComponent on 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 subscribe 方法来做到这一点，但这不起作用.

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

谁能帮我解决这个问题.

Can someone help me fix this.

登录服务

export class LoginService{

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

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

登录组件

OnInit{

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

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

}

重置组件

OnInit(){

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

}

推荐答案

在 LoginService 中尝试使用以下代码.

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

@Injectable()
export class LoginService {

   currentMessage = new EventEmitter();

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

并在提交函数中移动您的 ResetComponent 代码.

And move your ResetComponent code in submit function.

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

谢谢.
