　　　　　　//本方法以上所有步驟，都是為了從數據庫獲得數據：$list

　　　　　//以下兩行，固定方式，語法。輸出。

        $list=keysortExcel($list,array('loanid','loanname','branchname','nickname','adminrealname','loanterm','money','paiedmoney','earnmoney','status','isfailed','dateline','startpaytime','lasttime'));
        exportexcel($list,array('標的ID','貸款名稱','所屬地區','投標用戶','理財經理','借款期限','投標金額','已償還金額','已賺取金額','投標方式','是否流標','投標日期','計息日期','截止日期'),'投資業務統計-'.time());
    }

前台傳入數據：

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 傳過去的數據
