How to get the element in my table's cell?

<html>
<head>
<script language="javascript" >
function smanPromptList(objInputId){//I cut my file //short to find where is wrong.
      	var objInputCel = document.getElementById(objInputId).rows[0].cells[1];
        var objInput = objInputCel.childNodes[0]; 
        document.write(objInputCel.innerText);//I tried //this wondering if it will display"apple",but it didn't.
}
</script>
</head>
<body onload="smanPromptList('tb1')" bgcolor="#ffffff">
<table id="tb1" width="100%" border="0" cellspacing="3%" cellpadding="3%">
  <tr>
    <td id="td0" name="td0" width="300">
      <form id="form0" name="form0" method="post" action="">
      	pv：<input type="text" name="htmlText" id="htmlText"/>
    	</form>
    </td>
    <td width="300">
      apple
    </td>
  </tr>
</table>
<script language="javascript" >
	document.getElementById('htmlText').value = "";
</script>
</body>

your problem is document.write( ). if it is used after the page finished loading, it erases your whole document, including all styles and scripts.

Yeah,that will erases,and I thought it'll be apple displayed.But I just see undefined,that' s puzzling me.
