最佳答案
我试图在我的Angular应用程序中制作一个非常简单的表单,但无论如何,它都不起作用。
Angular 2.0.0 RC5
无法绑定到'formGroup',因为它不是'form'的已知属性
<form [formGroup]="newTaskForm" (submit)="createNewTask()"><div class="form-group"><label for="name">Name</label><input type="text" name="name" required></div><button type="submit" class="btn btn-default">Submit</button></form>
import { Component } from '@angular/core';import { FormGroup, FormControl, Validators, FormBuilder } from '@angular/forms';import {FormsModule,ReactiveFormsModule} from '@angular/forms';import { Task } from './task';
@Component({selector: 'task-add',templateUrl: 'app/task-add.component.html'
})export class TaskAddComponent {
newTaskForm: FormGroup;
constructor(fb: FormBuilder){this.newTaskForm = fb.group({name: ["", Validators.required]});}
createNewTask(){console.log(this.newTaskForm.value)}}
import { NgModule } from '@angular/core';import { BrowserModule } from '@angular/platform-browser';import { FormsModule } from '@angular/forms';
import { routing } from './app.routing';import { AppComponent } from './app.component';import { TaskService } from './task.service'
@NgModule({imports: [BrowserModule,routing,FormsModule],declarations: [ AppComponent ],providers: [TaskService],bootstrap: [ AppComponent ]})export class AppModule { }
为什么我犯了这个错误?我错过了什么吗?
