美好的一天,Yongke Yu!尝试使用Konstanin Levedev-« Sortable »(~6KB)的图书馆.在NPM - «sortablejs».这个库非常灵活,没有依赖性,具有触摸支持,能够动态添加项目.

我为你做了一个演示.尝试添加和删除行,然后重新排序.

            <p>These healthy muffins are the perfect treat for when you are feeling something sweet. It is so much better to bake muffins yourself as you can choose exactly what you put in them, meaning you can stay away from refined sugars and preservatives! These are perfect for bringing to a brunch or just sharing with your friends.
