javascript スクロール機能をつけるとき

Last updated at Posted at 2020-07-12

JavaScriptでスクロール機能をつけたいときのコードです

htmlタグの一番下に以下のコードを記入します。

<script>
$(function () {
      $('a[href^=#]').click(function () {
        var adjust = -50;
        var speed = 400;
        var href = $(this).attr("href");
        var target = $(href == "#" || href == "" ? 'html' : href);
        var position = target.offset().top + adjust;
        $('body,html').animate({scrollTop: position}, speed, 'swing');
        return false;
      });
    });
</script>

※adjustという変数は調整の意味です。
