layui的动态下拉选

    <!--将授权问卷id全部查询出来-->
            <div class="layui-inline">
                <label class="layui-form-label">选择问卷</label>
                <div class="layui-input-inline">
                    <select name="qnId" id="qnId" >
                        <option value="">请选择</option>
                    </select>
                </div>
            </div>

　　有jquery的引入

   $.ajax({
          type: "post",
          url: "/custQuestionnaire/list",
          data:{page:1,limit:1000},
          success: function (result) {

              if(result.code==200){// qnId
                  $.each(result.data,function(i,v){
                      console.log(i+" : "+v.id)
                      $("#qnId").append("<option value='"+v.id+"'>"+v.title+"</option>");
                  });
                  form.render('select');
              }
          }
      });
