如何在angular 2中添加表的记录限制

<form>
  <input type="text" name="name" minlength="5" required>
  <button type="submit">提交</button>
</form>

import { Component } from '@angular/core';
import { FormGroup, FormControl } from '@angular/forms';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      name: new FormControl('')
    });
  }
}

import { Component } from '@angular/core';
import { FormGroup, FormControl } from '@angular/forms';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      name: new FormControl('')
    });
  }

  onSubmit() {
    if (this.myForm.valid) {
      // 表单验证通过，可以执行相应的操作
      console.log('表单验证通过');
    } else {
      // 表单验证不通过，可以进行错误处理
      console.log('表单验证不通过');
    }
  }
}
