各个浏览器的保存浏览是不同的,只需要写服务端的代码:可以参考我项目中的代码:
if($_GET['download'])
{
$file_type = $_GET['download'];
}
else
exit;if($file_type == "cms_config")
$file = '/config/cmscof.cfg';
elseif($file_type == "tsu_config")
$file = '/config/config';
else
exit;
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
}
if($_GET['download'])
{
$file_type = $_GET['download'];
}
else
exit;if($file_type == "cms_config")
$file = '/config/cmscof.cfg';
elseif($file_type == "tsu_config")
$file = '/config/config';
else
exit;
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
}
function BrowseFolder(){
try{
var Message = "请选择文件夹"; //选择框提示信息
var Shell = new ActiveXObject( "Shell.Application" );
var Folder = Shell.BrowseForFolder(0,Message,0x0040,0x11);//起始目录为:我的电脑
//var Folder = Shell.BrowseForFolder(0,Message,0); //起始目录为:桌面
if(Folder != null){
Folder = Folder.items(); // 返回 FolderItems 对象
Folder = Folder.item(); // 返回 Folderitem 对象
Folder = Folder.Path; // 返回路径
if(Folder.charAt(Folder.length-1) != "\\"){
Folder = Folder + "\\";
}
document.all.savePath.value=Folder;
return Folder;
}
}catch(e){
alert(e.message);
}
}
