Increment value of textinput with jquery like spinner

Question

Hi folks Trying to create a simple spinner effect with Jquery, i.e. two buttons (up & down) with a text field. The upbutton increases the value while the down button decreses the value. increment steps + or - 1.

Any suggestions as ui.spinner is most def. not working and I am new to jquery. musty be something like $(#up).click (function ( /*SOMETHING GOES IN HERE but what?*/ )) and likewise for #down. both to set adjust the input text field say id #test as above.

<button id="inc">+</button>
<button id="dec">-</button>
<input type="text" name="qty" value="0" />

<script type="text/javascript">
  $(function(){
    $("#inc").click(function(){
      $(":text[name='qty']").val( Number($(":text[name='qty']").val()) + 1 );
    });
    $("#dec").click(function(){
      $(":text[name='qty']").val( Number($(":text[name='qty']").val()) - 1 );
    });
  });
</script>

Maybe something like:

$(document).ready( function() {
  var el = $('#test');
  function change( amt ) {
    el.val( parseInt( el.val(), 10 ) + amt );
  }

  $('#up').click( function() {
    change( 1 );
  } );
  $('#down').click( function() {
    change( -1 );
  } );
} );
