http://docs.jquery.com/Ajax/jQuery.ajax#options
var path = $(this);
var addtask = $('.inputtask').val();
$.ajax({
url: 'todolistadd.php',
data: 'addtask= ' + addtask,
success: function(msg) {
alert(msg);
}
});

echo $newid;
And, you can simplify that some. The 2nd query is unnecessary.
header('Content-type: text/plain');
echo mysql_insert_id();
I do hope you'll do some validation/sanitizing of that POSTed input,
though. I suggest you have a look at the MDB2 PEAR module.
