ajax jQuery 实现文件上传



1.上传jsp。

<table cellpadding="0" cellspacing="0" border="0" class="ktable_9" >
        <tr>
            <td><input type="file" name="upoadFileName" id="upoadFileName"><a  href="＃" onclick="uploadFile（）;return false;"><span><span>上传</span></span></a></td>
            </tr>
            <tr>
            <td>&nbsp;</td>
            </tr>
        </table>




2.下面是前端的js脚本：

function uploadFile（）{
                var myurl="/uploadMyFile.do？tenderInfoId="+tenderInfoId;
         jQuery.ajaxFileUpload（
                   {
                url:myurl，          
                secureuri:false，
                            fileElementId:""upoadFileName""，   --上传文件对应的文本域的id                    
                dataType: ""json""，                                    
                success: function （data， status）          
                {    
                    alert（""上传成功""）;
                                  }，
                error: function （data， status， e）           
                {
                   alert（""上传失败""）;
                }
            } ）;
    }





3.这是后台的action:
public ActionForward uploadMyFile（ActionMapping mapping，
ActionForm form， HttpServletRequest request，
HttpServletResponse response） throws Exception {
/* =============禁止缓存============== */
response.setHeader（"Pragma"， "no-cache"）;
response.setHeader（"Cache-Control"， "no-cache"）;
response.setHeader（"Expires"， "0"）;
