hello,

i am using this to upload file, it works well the only problem is

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    $(function () {
        $("body").on("click", "#btnUpload", function () {
            $.ajax({
                //url: '../inbox/Handler.ashx',
                url: '<%= ResolveUrl("~/inbox/Handler.ashx")%>' + "?msg=" + $('[id*=txtmsg]').val() + "&chatid="+$('[id*=hdnchatid]').val() ,
                type: 'POST',
                data: new FormData($('form')[0]),
                cache: false,
                contentType: false,
                processData: false,
                success: function (file) {
                    $("#fileProgress").hide();
                    $("#lblMessage").html("");
                    $('[id*=txtmsg]').val("");
                    $("input[type='file']").val("");
                     document.getElementById("btncancel").style.display="none";
                  

                  
                },
                xhr: function () {
                    var fileXhr = $.ajaxSettings.xhr();
                    if (fileXhr.upload) {
                        $("progress").show();
                        fileXhr.upload.addEventListener("progress", function (e) {
                            if (e.lengthComputable) {
                                $("#fileProgress").attr({
                                    value: e.loaded,
                                    max: e.total,
                                    
                                });
                            }
                        }, false);
                    }
                    return fileXhr;
                }
            });
        });
    });


</script>

 i already have .js version 1.10.2 so adding below script again make conflict but when i remove the below version of script the above solution of uploading file works

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

  but  after successful upload this part does not fire

success: function (file) {
    $("#fileProgress").hide();
    $("#lblMessage").html("");
    $('[id*=txtmsg]').val("");
    $("input[type='file']").val("");
    document.getElementById("btncancel").style.display="none";
},
