If I understand your question, it is not the jQuery version that is the problem. With all due respect, your design is incorrect. However, since you are using version 1.4.2 of jQuery, you should be aware that you must use jQueryUI 1.8.24 or less. Therefore:
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.24/jquery-ui.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.24/themes/smoothness/jquery-ui.css" />
</head>
Back to your question. Since you are uploading a file, then you are POSTing the file (probably via a form, or better yet AJAX) to another PHP file. Javascript won't have a chance to show it.
What will work (and for everything to happen/display the way you want) is to add the document using AJAX. You can do it manually, or I can recommend one of these plugins:
Just to prove my point, though, in the following example I emulated "adding a file" using js/jQ. As you can see in the demo, the new data appears just fine.
jsFiddle demo
$('#add_file').click(function() {
$('#documents').find('table').append('<tr><td>002</td><td>another_file.doc</td></tr>');
});
See these SO posts for some simple examples of how AJAX works:
Please upvote any posts that you find helpful.
Below is a code example of what you want to do. The example works, but I am disappointed to see not with your versions of jQuery/jQueryUI sadly. Please try the example (copy/paste code into a .PHP document on your web server) with the current version and then again with the 1.4.2/1.8.24 versions -- current version works fine. (You can switch between versions easily by uncommenting/comment the obvious tags in the head) If nothing else, perhaps you can use this working example as a starting point, at the least.
Note that I did not do anything on the back end to receive/process the uploaded file. I had to cut the example somewhere, so did not write the back-end processing files. But here is a link where you can see an example: http://hayageek.com/ajax-file-upload-jquery/ (scroll down to section "Server Side")
**Fully Working Example: Just copy/paste into PHP doc on your server **
