springMVC uploadify的应用

<form><input id="uploadify" name="file" type="file"></input> <ahref="javascript:$('#uploadify').uploadify('upload','*')">上传</a>|<a href="javascript:$('#uploadify').uploadify('cancel')"> 取消上传</a></form><script type="text/javascript">function query2() {var startTime2 = $('#start2').datetimebox('getValue');var endTime2 = $('#end2').datetimebox('getValue');$.ajax({type : 'POST',url : 'dataGrid.do', //用户请求数据的URLdata : {pageNumber : 1,pageSize : 2,//默认先为2start : startTime2,end : endTime2},error : function(XMLHttpRequest, textStatus,errorThrown) {alert(textStatus);},success : function(data) {// alert(data);test = eval("(" + data + ")"); ////转换为json对象//  alert(test);$('#dg').datagrid('loadData', test);}});}$(function() {//默认关闭dialog$('#dlg').dialog('close');});$(function() {$('#uploadify').uploadify({'swf' : '${ctxStatic}/uploadify/uploadify.swf','uploader' : 'upload.do','buttonText' : '浏览','fileTypeDesc' : '添加你要上传的文件','height' : 25,'width' : 70,'auto' : false,'multi' : true,'method' : 'post',//'progressData' : 'speed',//显示进度速度例如：35/kb// 'formData': {pid:'1'},  'fileObjName' : 'file','fileSizeLimit' : '100MB','removeTimeout' : 3,//移除提示成功时间'uploadLimit' : 3,//上传最大限度'fileTypeExts' : '*.*',//允许上传的类型'onQueueComplete' : function(queueData) {alert(queueData.uploadsSuccessful+ '个文件:上传成功！');window.location.reload();}//  ,'onUploadSuccess' : function(file, data, response) {///       alert(file.name +' :上传成功    保存路径为:' + data);// }});});</script>
