Im building a file upload with jQuery, but Im getting a jQuery error trying to set the attributes of the form:

$(document).ready(function () {

    $(#formsubmit).click(function () {



        var iframe = $('<iframe name=postframe id=postframe class=hidden src=about:none />');



        $('div#iframe').append(iframe);



        $('#theuploadform').attr(action, /ajax/user.asmx/Upload)

        $('#theuploadform').attr(method, post)

        $('#theuploadform').attr(userfile, $('#userfile').val())

        $('#theuploadform').attr(enctype, multipart/form-data)

        $('#theuploadform').attr(encoding, multipart/form-data)

        $('#theuploadform').attr(target, postframe)

        $('#theuploadform').submit();

        //need to get contents of the iframe



        $(#postframe).load(

            function () {

                iframeContents = $(iframe)[0].contentDocument.body.innerHTML;

                $(div#textarea).html(iframeContents);

            }

        );

    }

);





<div id=uploadform>

    <form id=theuploadform action=>

        <input id=userfile name=userfile size=50 type=file />

        <input id=formsubmit type=submit value=Send File />

    </form>

</div>
