javascript - ionic 4中的(按键)事件未触发

Question

根据此链接https://ionicframework.com/docs/api/input#events ionic 支架按键 在浏览器中运行良好但在移动设备中未触发的事件

html

<ion-item>
  <ion-label>Default Label</ion-label>
  <ion-input (keypress)="test($event)"></ion-input>
</ion-item>

ts

test(event){

console.log(event);
 e.preventDefault();
}

the above code works fine in ionic serve not in mobile device

据此https://developer.mozilla.org/en-US/docs/Web/API/Document/keypress_event按键被贬低我不明白

Events i tried: keypress, keydown, keyup, ionblur, ionChange, input,..etc Either it is not working or it or preventdefault is not working

Answer 1

根据您自己的第一个链接，我猜您正在寻找事件 ionInput Emitted when a keyboard input ocurred. :

<ion-item>
  <ion-label>Default Label</ion-label>
  <ion-input (ionInput)="test($event)"></ion-input>
</ion-item>
