Angular 中如何使用模板驱动表单？

Question

1. 导入 FormsModule 模块

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

@NgModule({
  imports: [BrowserModule, FormsModule], // we add FormsModule here
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

2. 实际应用

<form novalidate>
  <input type="text" name="name" ngModel required>
  <input type="text" name="street" ngModel minlength="3">
  <input type="text" name="city" ngModel maxlength="10">
  <input type="text" name="zip" ngModel pattern="[A-Za-z]{5}">
</form>
