scrollTo() Prototype help!

JavaScript
1

Hello,

I have this issue on how to implement this scrollTo() method in my existing javascript codes.

The function is I have a form, and when I update my form it has preview. And I want it every time I update it scroll to to the preview.

I have this two javascript functions:

	function highlightPreview(idName)
	{
		var undef;
		var myPreview = arrElements[idName]._preview;
		
		if (myPreview != undef)
		{
			myPreview.style.background = "#ffff99";
			arrElements[idName].scrollTo();
		}
	}


	function updatePreview(idName, keepBackground)
	{
		var undef;
		var myElement = arrElements[idName]._element;
		var myPreview = arrElements[idName]._preview;
		var myBackground = arrElements[idName]._background;
		
		if (myPreview != undef)
		{
			if (!keepBackground) myPreview.style.background = myBackground;
			
			if (myElement.name.search(/\\_cmd/) == -1)
				myPreview.innerHTML = myElement.value;
				arrElements[idName].scrollTo();
			else
				myPreview.value = myElement.value;
		}
	}

Here is my HTML:

				<tr class="Row">
					<td class="LabelCol" width="25%">'Used Password' Message:</td>
					<td class="ValueCol" width="75%" colspan="2">
						<textarea
							name="xp_txtUsed"
							id="xp_txtUsed"
							cols="64"
							rows="6"
							
							onFocus="highlightPreview(this.name)"
							onBlur="updatePreview(this.name)"
							onChange="updatePreview(this.name)"
							onKeyUp="updatePreview(this.name, true)"
						><%= FormVals.Item("xp_txtUsed") %></textarea>
					</td>
				</tr>

My objective is apply scrollTo() method inorder for me to see the preview scroll to when I updated the form.

Please let me know how to do this.

Thanks in advance…
