uplaodify动态修改上传路径

其实很简单，就是动态修改参数。第一次写东西，还是晒一下

	<input id="fileupload" name="fileupload" type="file" />
									<a href="javascript:$('#fileupload').uploadifyUpload();">开始上传</a>
									|
									<a href="javascript:$('#fileupload').uploadifyClearQueue();">清除队列</a>
								</div>
								<div id="result"></div>

下面是js

$(document).ready(function() {
	            var loadpath= "/"+ "defualt";
	            	
	            addlist();
	           $("#subjectAdd").bind("change",function(){
	            loadpath= "/"+$("#subjectAdd option:selected").val();
	            alert(loadpath);
	           $('#fileupload').uploadifySettings('folder',loadpath);

	            });
	            
			  $('#fileupload').uploadify({
			    'uploader'  : 'uploadify/uploadify.swf',
			    'script'    : 'upload',
			    'cancelImg' : 'uploadify/cancel.png',
			    'folder'    : loadpath,
			    'fileDataName'   : 'fileupload',
			    'buttonText'     : 'choose Files',   
			    'auto'           : false,   
			    'multi'          : true,   
			    'sizeLimit'      : 1073741824,   
			    'simUploadLimit' : 3 ,
			    'onComplete'     : function (event, queueID, fileObj, response, data){
                  $("#result").html(response);//显示上传成功结果
                 setInterval("showResult()",2000);//两秒后删除显示的上传成功结果
               }
			  
			    			    
			  });
			});

		function showResult(){//删除显示的上传成功结果
	          $("#result").html("");
	        }
	      
	        function addlist(){
            	var zf = $("#dialogAdd .validateTipsl");
            	$.ajax({
      				type: "POST",
      				contentType: "application/x-www-form-urlencoded;charset=UTF-8",
      				url: "getSubjectList",
      				data: {
      				 
      				},
      				dataType: "json",
      				success: function(result){
      					var content="";
      					$.each(result,function(i,item){
      						content += "<option value="+item.subjName 
      								+">"+item.SubjChName+"</option>";
      					});
      					$("#subjectAdd").append(content);
      				},
      				error: function(msg){
      					//updateTips("发生未知异常", tips);
      				}
      			});}

在action中 接到folder就可以了
顺便说一句在后台 知道类型为file 的 名称和你被选择html一样就可以了
