Trapping for PDF Type and file size in a UPLOAD form...

I am trying to create an UPLOAD form and need to figure a way to only  
allow PDF files to be selected. Something like:

<html>
<body>
	<form enctype="multipart/form-data" action="upload.php" method="post">
		<input type="hidden" name="MAX_FILE_SIZE" value="1000000"  
accept="application/pdf" />
		Choose a file to upload: <input name="uploaded_file" type="file" />
		<input type="submit" value="Upload" />
	</form>
</body>
</html>

It is documented online that I can pass a parameter ACCEPT="applaction/ 
pdf",  BUT it is not recognized in most browsers.

It was suggested by someone that I could trap for this using a  
JAVASCRIPT. Can someone assist with a snippet of javascript code to  
trap for this for me? This is the end result I need:

If the user selects a file that IS NOT a PDF file, display an  
javascript alert "You can only upload PDF files. Please try again."

If the user selects a PDF file greater than 1MB, display an javascript  
alert "File uploads may not exceed 1M in file size. Please try again."

I appreciate any help that can be offered. Thanks in advanced!
