layui 数据表格复选框实现单选功能的例子

//点击选中(单选)
//单击行勾选checkbox事件
  $(document).on("click",".layui-table-body table.layui-table tbody tr", function () {

    //获取已选中列并取消选中
    var trs = tableDiv.find(".layui-unselect.layui-form-checkbox.layui-form-checked").parent().parent().parent();
      for(var i = 0;i<trs.length;i++){
