页面代码：

<html>
    
    <script type="text/javascript" src="js/jquery.js"></script>
    <script type="text/javascript" src="js/ajaxfileupload.js"></script>

    
    <script type="text/javascript">
        function ajaxFileUpload(){
            $.ajaxFileUpload(
                 {
                url:'update.do?method=uploader',            //需要链接到服务器地址
                secureuri:false,

                data: {
                  'csrfmiddlewaretoken': getCookie('csrftoken')
                 },
                fileElementId:'houseMaps',                        //文件选择框的id属性
                dataType: 'xml',                                     //服务器返回的格式，可以是json
                success: function (data, status)            //相当于java中try语句块的用法
                {
                    $('#result').html('添加成功');
                },
                error: function (data, status, e)            //相当于java中catch语句块的用法
                {
                    $('#result').html('添加失败');
                }
            }

            );

        }
    </script>
</head>

<body>
    <form method="post" action="update.do?method=uploader" enctype="multipart/form-data">
        <input type="file" id="houseMaps" name="houseMaps"/>
        <input type="button" value="提交" onclick="ajaxFileUpload()"/>
    </form>
    <div id="result"></div>

</body>
</html>

服务器端代码：

from django.core.files.uploadedfile import UploadedFile

class UploadFiles(View):

    def post(self,request,type):
        file = request.FILES.values()[0]
        wrapped_file = UploadedFile(file)
        upload = UploadNeed.objects.create(type= type, storage=wrapped_file)
        upload.save()
        msg = {'state': True, 'msg': u'上传成功'}
        return HttpResponse(simplejson.dumps(msg))
