无法绑定到“ngModel”，因为它不是“input”的已知属性

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

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule // 添加FormsModule到imports数组
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

<input [(ngModel)]="yourVariable" name="yourInputName">

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  yourVariable = ''; // 初始化属性
}

<input [(ngModel)]="yourVariable" name="yourInputName">
