ASP编程：asp完成语音上传

Active Server Page技术为应用开发商提供了基于脚本的直观、快速、高效的应用开发手段，极大地提高了开发的效果。在讨论ASP的安全性问题之前，让我们来看看ASP是怎么工作的。   ＜script language="javascript">

function openScript(url, width, height){
var Win = window.open(url,"openScript",'width=' + width + ',height=' + height + ',resizable=1,scrollbars=yes,menubar=no,status=yes' );
}
＜/script>

＜form action="save.asp" method="POST" enctype="multipart/form-data">
＜tr>
＜td width="17%" height="66">选择语音＜/td>
＜td height="66" colspan="5">

当然了,现在国内CRM厂商的产品与其说是CRM,但从至少从我的角度分析上来看,充其量只是一个大型的进销存而已了,了解尚浅,不够胆详评,这里只提技术问题

兴趣爱好，那么你无须学编程，申请一个域名和空间，在网上下载一些免费开源的CMS系统，你不用改代码，只须熟悉它们的后台操作，像office一样简单方便，很快就能建一个站点，很多站长都是这样做的
