<script type="text/javascript"> {literal} $(document).ready(function(){ $("#s1").change(function() {  var idcat=this.value; alert(idcat);  $.ajax({ type: "get", url: 'product_modify.php', data: {idcat:idcat}, success: function(data) { alert(data); alert("success"); } }); }); }); {/literal} </script>

and php codes 

 if(isset($_get['idcat'])){      $idc= $_get['idcat'];     echo $idc;     }

var idcat=this.value;

should be

var idcat=$(this).val();
