我有一个工作的excel下载文件，但首先我想弹出一个下载窗口。现在，它只会在没有保存文件窗口的情况下自动生成。我怎样才能做到这一点。请帮帮我。
<html>
<head>
<script language="javascript">
function download()
{
window.location='report.xls';
}
</script>
</head>
<body alink="#00FF66" link="#00CC00">
<h1 align="center"><a href="javascript:void(0);" onClick="download();">Download Excel Report</a></h1>
<?php
require_once("db.php");
require_once("excelwriter.class.php");
$excel=new ExcelWriter("report.xls");
if($excel==false)
echo $excel->error;
$myArr=array("Model","Code","Desc","Stock Requested","Stock Received", "Diff", "On hand");
$excel->writeLine($myArr);
$sql="SELECT allinvty3.*, barcode.* , sample.*, count(barcode.itemcode) as icount from barcode
INNER JOIN sample on barcode.itemcode = sample.in_code
INNER JOIN allinvty3 on barcode.itemcode = allinvty3.in_code
group by barcode.itemcode";
$result = $conn->query($sql);
if($sql!=false)
{
$i=1;
while($row = $result->fetch_assoc())
{
$myArr=array($row['ecr_desc'],$row['itemcode'],
$row['ite_desc'],$row['tqty'],$row['icount'], $row['icount'],
$row['icount']);
$excel->writeLine($myArr);
$i++;
}
}
