[ASP.NET]uploadify简单使用讲解
背景:在用户控件中使用html 的file控件或者ASP.NET的FileUpLoad控件都无法获取到文件,于是想到听说过的uploadify
uploadify官网:www.uploadify.com
直接官网下载相关文件,发现里面有几个php文件,为了不用还配置php于是修改为ASP.NET用法
添加UploadHandler.ashx文件及修改代码:
public class UploadHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; context.Response.Charset = "utf-8"; HttpPostedFile file = context.Request.Files["Filedata"]; string uploadPath = HttpContext.Current.Server.MapPath(@context.Request["folder"]) + "\\"; if (file != null) { if (!Directory.Exists(uploadPath)) { Directory.CreateDirectory(uploadPath); } file.SaveAs(uploadPath + file.FileName); //下面这句代码缺少的话,上传成功后上传队列的显示不会自动消失 context.Response.Write("1"); } else { context.Response.Write("0"); } }
在ascx页面引入3.1版本的uploadify
<link rel="stylesheet" type="text/css" href="../jslib/uploadify/uploadify.css" /> <script type="text/javascript" src="../jslib/uploadify/jquery-1.7.2.min.js"></script>//uploadify官网说明1.7.2+,既然推荐1.7.2那就是这个版本 <script type="text/javascript" src="../jslib/uploadify/jquery.uploadify.min.js"></script>
在加入js
$(function() {
$(‘#ftcFormHolder_FpgForm_btnHtmlFile1‘).uploadify({
‘swf‘ : ‘../jslib/uploadify/uploadify.swf‘,
‘uploader‘ : ‘../jslib/uploadify/UploadHandler.ashx‘,
‘buttonText‘: ‘浏览‘,
‘multi‘: false,
‘onUploadComplete‘ : function(file) {
alert(‘The file ‘ + file.name + ‘ finished processing.‘);
}
});
});
以上为简单使用,其他参数或者事件可参考官网
