Setting enctype attribute in IE8

It can't set the enctype attribute in IE8:

f.attr("enctype","multipart/form-data");//it doesn't work in IE8, form doesn't send a content of an upload file
f.attr("id","idx");//it works right
f.append('<input type="file" name="..." />');

It works in FF, but not in IE8. Only "enctype" attribute can't set with attr() method in IE8.

Code for IE8:

f=$("<form enctype="multipart/form-data"/>");

Example that bug:

    <title>Example page for jQuery attr() bug - it can't set enctype attribute in form tag</title>
    <script src="" type="text/javascript"></script>

    <script type="text/javascript">
      $(document).ready(function() {
         //next two lines don't work in IE8, but they work in FF        
         f=$('<form />');
         //comment two previous lines, uncomment next line and it work in IE8 
         //f=$('<form enctype="multipart/form-data" />');
         f.append('<input type="file" name="ffile" id="ffile" /><input name="fsubmit" id="fsubmit" type="submit">'); 
 if(@basename(htmlspecialchars($_FILES['ffile']['name'])))echo "Browser has sent a file ".$_FILES['ffile']['name'];
 else echo "Browser hasn't sent a file.";

Thanks for taking the time to contribute to the jQuery project by writing a bug report.

This is a known problem. You should be able to workaround this by doing

var f=$("<form>");
//note the camelcased attribute name works for most browsers including IE8
f.attr("encType", "multipart/form-data");
//needed for browsers where setting enctype isn't enough e.g. IE6/7
f.attr("encoding", "multipart/form-data");

Eventually this will be fixed in jQuery directly and the workaround no longer needed. You can check the ticket mentioned below for progress on this issue.
