$('#musicCategoryListContainer').on('click', '.musicCategoryItem', function () {
          $(this).siblings().removeClass("musicCategoryChecked");
          $(this).addClass("musicCategoryChecked");
          //alert($(($(this).find(".data"))[0]).attr("ItemId"));
        });

<ul class="site-doc-icon site-doc-anim margin15" id="musicCategoryListContainer">
      <!--<li class="musicCategoryChecked musicCategoryItem">
        <div class="layui-anim" data-anim="layui-anim-scaleSpring">弹簧式放大</div>
        <div class="code">layui-anim-scaleSpring</div>
      </li>-->
    </ul>
