     var result = displaying.split(",");

  var dataintext = result[0];

    $('#sub').val(dataintext);

   }

    var input = { "text" : "testing entry data",
               "displaying" : "hello"
            };  

       $.post('some.action',input,somecallback,"json");
  }

    $(function(){
    $('#field').click(function(){
     test();
     return false;
     });

 </script>
 </head>

    try changing the order you’re linking the scripts, jquery should be before you like any file using jquery 

    <SCRIPT type="text/javascript" src="javascript/jquery.js"></SCRIPT>
<SCRIPT type="text/javascript" src="javascript/json.js"></SCRIPT>
<SCRIPT type="text/javascript" src="javascript/jquery.form.js"></SCRIPT>

    Also, don’t use onclick use:

    $('#field').click(function(){
   test();
});
