JSのconfirmでダイアログのボタン押下時の処理の分岐

Last updated at Posted at 2018-11-21

HTML側で以下のボタンを押下した場合にOKorキャンセルのwindowを出したい。

hoge.html
<form method="POST" id="id" action="/users/delete/">
    <input type="submit" value="削除">
</form>

jsのconfirmメソッドを使用してみる。

hoge.html

//jsの処理
<script type="text/javascript">
  function Check(){
      var checked = confirm("削除します");
      if (checked == true) {
          return true;
      } else {
          return false;
      }
  }
</script>

//inputタグにonClick追記
<form method="POST" id="id" action="/users/delete/">
    <input type="submit" value="削除" onClick="return Check()">
</form>

因みにonClickにreturnを記述しないと、
キャンセル押下時もactionの処理に遷移するので注意する。
