更新時(shí)間：2017年07月28日 11:30:23 作者：小倔驢

最近做個(gè)項(xiàng)目，需要實(shí)現(xiàn)移動(dòng)端左滑刪除功能，當(dāng)時(shí)js代碼將網(wǎng)上找的進(jìn)行刪減優(yōu)化，下面通過(guò)本文給大家分享基于JS實(shí)現(xiàn)移動(dòng)端左滑刪除功能，感興趣的朋友一起看看

廢話不多說(shuō)了，直接給大家貼代碼了，具體代碼如下所示：

<div class="wrap pay-wrap" id="lists">
    @foreach (var item in Model)
    {
      <div class="pay-list" style="height:90px;margin: 10px 15px 10px 15px;" id="@item.UID">
        <div class="pay-each" style="height:90px;margin-bottom:0; border-radius: 5px;">
          <div class="pay-order-teacher" style="background-image:url(@item.DiseaseInformation.ListPicPath);height:70px;border-radius:0" onclick="Turn('@item.DiseaseInfoID')"></div><div class="detaildiv" style="padding:0;padding-top:10px" onclick="Turn('@item.DiseaseInfoID')">
            @(item.DiseaseInformation.Title.GetSubstr(60))
          </div>
          <div style="height:20px;margin-right:10px;line-height:20px;vertical-align:middle" onclick="Turn('@item.DiseaseInfoID')">
            <span style="float:left;color: #808080;line-height:2;vertical-align:bottom;width:70%">來(lái)源：@(item.DiseaseInformation.Source)</span>
            <span style="float:left;color: #808080;line-height:2;vertical-align:bottom;width:30%"><img src="~/Content/img/yueduliang.png" style="height:20px" /> @(item.DiseaseInformation.BrowseNum)</span>
          </div>
          <div class="pay-order-swiper" style="height:90px;margin-left:15px;width:80px"><a href="javascript:;" rel="external nofollow" onclick="del('@item.UID')" class="btn btn-red pay-order-btn pay-order-del" style="height:90px;line-height:90px;width:105px;font-size:18px">刪除</a>
          </div>
        </div>
      </div>
    }
  </div>
