javascript - Angular/形式整数验证器

Question

如何验证我的数字输入字段仅接受整数而不接受任何类型的十进制数字(逗号/点)？
代码Component

import { FormGroup, FormBuilder, Validators } from '@angular/forms';

this.savingData = this.formBuilder.group({
  amount: ['', Validators.required], // only accept integer 123000
});

HTML

<ion-input type="number" min="1" inputmode="numeric" formControlName="amount" placeholder="{{ 'SAVINGS.amount' | translate }}" ></ion-input>

任何想法？

你可以试试 Angular Reactive 表单 pattern validator

this.savingData = this.formBuilder.group({
  amount: ['', [Validators.required, Validators.pattern("^[0-9]*$")]], // only numbers
});
