動的アイテムに対してeventを発生させる

Last updated at Posted at 2016-11-16

jQueryでdelegateを効かせないと、動的なアイテムに対してeventを発生させることができない。
引数を2つとるとdelegateが効くらしい。謎。

✕delegate

  $("input, textarea").on('change', function() {
    // 入力内容が更新されている場合は、isChangedフラグをtrueにします。
    isChanged = true;
    console.log('isChanged = true;');
  });

◯delegate

  $("body").on('change', 'input, textarea', function() {
    // 入力内容が更新されている場合は、isChangedフラグをtrueにします。
    isChanged = true;
    console.log('isChanged = true;');
  });
