　　　　　　//本方法以上所有步骤，都是为了从数据库获得数据：$list

　　　　　//以下两行，固定方式，语法。输出。
         $list=keysortExcel($list,array('loanid','loanname','branchname','nickname','adminrealname','loanterm','money','paiedmoney','earnmoney','status','isfailed','dateline','startpaytime','lasttime'));
         exportexcel($list,array('标的ID','贷款名称','所属地区','投标用户','理财经理','借款期限','投标金额','已偿还金额','已赚取金额','投标方式','是否流标','投标日期','计息日期','截止日期'),'投资业务统计-'.time());
     }

前台传入数据：

 function doExportt(id)
 {
     var id = id;
     $.post('<{:U('Tongji/index_edit_doExport')}>',{id:id}, function(res){
             if(!res.status){
                 $.messager.alert('提示信息', res.info, 'error');
             }else{
                  window.open(res.info,'_blank');
             }
     }, 'json');
 }

其中，{id:id}，是 post 传过去的数据
