Jquery :getting Object Expected Error when using the onchange() for textfield -

i have textfield

<input type = "text" name ="text1" id ="text1" onchange="displayresult()">   function displayresult(){    alert("testing") } 

it giving object expected error in ie6.o . when debug in mozilla pointing function name in way

`function onchange(event) {      displayresult(); //the cursor pointed on here  }` 

how can correct

going description , example, think displayresult() function declaration below 'onchange' input text usage. solution below uses document.ready() event, , uses id selector , .change() register 'onchange' needs. can remove onchange="displayresult();" in html if use code below

<script> function displayresult(){    alert("testing"); } $(document).ready(     function(event){      $("#text1").change(function(event){        displayresult();      }); }); </script>
