いつも忘れる ApplePencil対応

Last updated at Posted at 2020-05-13

Apple pencilなんで仕事してくれへんの

selectやinputをApple pencilで突きすぎてペン先が磨耗した人向け

動け!(切望)

const elm = document.getElementById('idDayo')
elm.addEventListener('touchstart', function(){
  elm.focus();
  elm.select();
})

cssにcusrosr:pointer;をつけると良いなど、探すといろいろな方法があるがどれも期待した動作をしない。。。
メンテナンス性は悪いけど、期待する動作はしてくれたのでおけまる

クラスで使用する場合

class NanikaClass{
  constructor() {
    this.elm = document.getElementById('idDayo')
    this.elm.addEventListener('touchstart', function() {
      this.elem.focus();
      this.elem.select();
    }
  }  
}

thisのスコープで悩む人(メンバー呼び出し思考)は.bind(this)で我慢して。
メンテナンス性を考えると、基底クラスにイベント登録用の関数を作って、そこで処理の共通化を行う方が良さそう。
