import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs/Observable';

import { Http, Response, Headers, RequestOptions } from '@angular/http';
import 'rxjs/add/operator/map';

@Component({
    selector: 'dashboard',
    templateUrl: './dashboard.component.html',
    styleUrls: ['./dashboard.component.css'],
    providers: [RemoteService]
})

export class DashboardComponent implements OnInit {
    allData = [];
    resu: string;
    errData: string;
    name: string = "Deepak";

    constructor(private http: Http){}

    ngOnInit(){}

    onSubmit(value: any) {
    //console.log(value.message);
    let headers = new Headers({ 'Content-Type': 'application/json'});
    let options = new RequestOptions({ headers: headers });
    let body = JSON.stringify(value);
    this.http.post('127.0.0.1/myProject/insertData.php', body, headers)
                .subscribe(
                    () => {alert("Success")}, //For Success Response
                    err => {console.error(err)} //For Error Response
                );                
    }    
}
