hi,

my major code could be:
<script language="JavaScript">
function test(){
var oDiv = document.getElementById("div1");
}
</script>
<table>
<tr>
<td><div id="div1">this is a test</div></td>
</tr>
</table>

my question is how to reference the <td> cell if i need to change its background color? is there something like oDiv.parentNode??

thanks a lot! 300 points will be awarded asap.

// try this
<script language="JavaScript">
function test(){
var oDiv = document.getElementById("div1");
oDiv.parentElement.style.backgroundColor = "#000080";

}
</script>
<table>
<tr>
<td>This is a the first test</td>
<td><div id="div1">this is a test</div></td>
<input type = 'button' value = 'Check' onClick = 'test()'>
</tr>
</table>

hi, sajuks:

thanks for your quick reply, but it's not working. i already solved this problem, the solution is :
<html>
 <head>
  <script language="javascript">
<!--

function hl( img ) {
  var row = findParent( img, "TR" );
  var table = findParent( row, "TABLE" );
  setBackgroundColorOnChildren( table, "TR", "#FFF" );
  row.style.backgroundColor="#ccc";
}

function findParent( ele, tag) {
    while ( ele.parentNode ) {
        if ( ele.parentNode.tagName == tag ) {
            return ele.parentNode;
        }

        ele = ele.parentNode;
    }
}

function setBackgroundColorOnChildren( parent, tag, color ) {
    var children = parent.getElementsByTagName( tag );

    for ( var i =0; i < children.length; i++ ) {
        children[i].style.backgroundColor = color;
    }

}

//-->

</script>
 </head>
<body>
<table>
 <tr><td><img src="images/sort_down.jpg" onclick="hl(this)"></td><td>data1</td><td>data2</td><td>data3</td></tr>
 <tr><td><img src="images/sort_down.jpg" onclick="hl(this)"></td><td>data1</td><td>data2</td><td>data3</td></tr>

 <tr><td><img src="images/sort_down.jpg" onclick="hl(this)"></td><td>data1</td><td>data2</td><td>data3</td></tr>
</table>
