            {foreach $user_list as $key => $v}
            <option value="{$v.id}">{$v.name}</option>
            {/foreach}
        </select>

 

 js：

layui.use('upload', function(){
      var upload = layui.upload;
      // 创建上传接口
      upload.render({
          elem: '#uploadBtn'
          ,url: 'importClient' // 改为你的上传接口URL
          ,accept: 'file' // 允许上传的文件类型
          ,exts: 'xls',
          data: {
                  admin_id:function (){
                      return $("#admin_id").val();
                  }
              }
          ,before: function(){
            // layer.load(); //上传loading
              layer.load(0,{shade: [0.5, '#eee'],time:0,content:'导入中...'});
          }
          ,done: function(res){
              layer.closeAll('loading'); //关闭loading
              // 上传完毕回调
              if(res.code == 200){
                  var str = '导入成功：'+res.success_num+"条,"+"失败："+res.fail_num+"条";
                  $("#msg").css("color","green");
                  $("#msg").text(str);
              }else{
                  $("#msg").css("color","red");
                  $("#msg").text(res.msg);
              }
              console.log(res);
          },error:function (){
              layer.closeAll('loading'); //关闭loading
          }
