How do I get the value of a textbox using jQuery?

on form submit, i am trying to grab the value of the textbox below and shove it in an url

<input type="text" style="width: 300px" id="fromAddress" name="from" value="" />&nbsp;

here is my jquery code:

<script type='text/javascript'>
     $(document).ready(function() {

         $(":submit").click(function(e) {

             var from = $("input#fromAddress").text;
             $('div#printdirec').html('<a target="_blank" href="http://maps.google.com/addr=' + from + '&daddr">Print Directions</a>');

         });

     });
</script>

when i look at the URL, it doesn't have the correct from address.

Just Additional Info which took me long time to find.what if you were using the field name and not id for identifying the form field. You do it like this:

For radio button:

var inp= $('input:radio[name=PatientPreviouslyReceivedDrug]:checked').val();

For textbox:

var txt=$('input:text[name=DrugDurationLength]').val();
