角度/形式整数验证器

Question

如何验证我的数字输入字段只接受整数而不接受任何类型的小数（逗号/点）？代码Componentimport { 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？

Answer 1

您可以尝试 Angular Reactive 表单模式验证器

this.savingData = this.formBuilder.group({

  amount: ['', [Validators.required, Validators.pattern("^[0-9]*$")]], // only numbers

});

Answer 2

尝试使用类似\d+. 它在Validators.pattern()
