css手风琴滚动到活页面的页面顶部

Question

我只使用没有JS的CSS手风琴菜单。 但我有一个问题。当我打开子菜单时，我的完整网站页面会自动滚动到此菜单按钮，并且单击子菜单并且不固定。我只想打开子菜单而不滚动我的页面。 这是一个解决方案吗？

Answer 1

跳跃是因为href="#id"

您有两个选项可将代码更改为不需要href="#id"

或

添加此

$('.accordion a').click(function (e) {
    var x = window.pageXOffset,
        y = window.pageYOffset;
    $(window).one('scroll', function () {
        window.scrollTo(x, y);
    })
});

我可以在哪里添加？由@pphil23

在<script></script>或

之前的</body>之间

<script src="js/file/path"></script>作为</body>之前的外部文件
