利用JavaScript实现移动端左滑删除功能介绍

最近做个项目，需要实现移动端左滑删除功能，当时js代码将网上找的进行删减优化，下面通过本文给大家分享基于js实现移动端左滑删除功能，感兴趣的朋友一起看看

废话不多说了，直接给大家贴代码了，具体代码如下所示：

    @foreach (var item in Model)
    {
      

        

          

            @(item.DiseaseInformation.Title.GetSubstr(60))
          
          

            来源：@(item.DiseaseInformation.Source)
            @@##@@ @(item.DiseaseInformation.BrowseNum)
          
          
删除
          
        

      

    }
