このapp.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'Employee Details';
employees = [{
name: "Sunil",
position: "Developer",
salary: 20000
}, {
name: "Vamshi",
position: "Java Developer",
salary: 30000
}, {
name: "Chethan",
position: ".Net Developer",
salary: 10000
}];
model: any = {};
model2: any = {};
addEmployee() {
this.employees.push(this.model);
this.model = {};
}
deleteEmployee(i) {
this.employees.splice(i, 1)
console.log(i);
}
myValue;
editEmployee(k) {
this.model2.name = this.employees[k].name;
this.model2.position = this.employees[k].position;
this.model2.salary = this.employees[k].salary;
this.myValue = k;
}
updateEmployee() {
let k = this.myValue;
for (let i = 0; i < this.employees.length; i++) {
if (i == k) {
this.employees[i] = this.model2;
this.model2 = {};
}
}
}
}
本のコードでのコードでありますapp.module.tsのコードです
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule
,FormsModule ,ReactiveFormsModule],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
今私は...私は問題を解決できなかった多くの方法を試してみましたし、データの埋められていないフィールドを追加したいいけない上記のコードに検証を追加したい。..

私は問題を解決できません。 –
