Access rows of a created table

[scott.loomis]

I have a javascript function that catches a click event of a row in a
table, but I am looking for a way to simulate a click in the first row
on page load.
function onRowClick(row)
{
//Do something

}
My table is actually a .Net Datagrid named dgrList, here is the grid
<asp:datagrid id="dgrList" runat="server" Width="448px"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px"
BackColor="White" CellPadding="3" GridLines="Horizontal"
autogeneratecolumns="False">
Now when I try to run something like
onRowClick(document.frmRemoteScan.dgrList.rows(0)) ;
I get the message that dgrList is null or not an object, and when I
loop throught the elements in my form, dgrList is not one of them(yes
it is between the form tags).
My question, is there a way to reference the created table via
javascipt? Or does anyone have a way to simulate the row clcik via
javascript

I figured this out, and wanted to help anyone that might stumble on
this post

try document.getElementById('dgrList').rows

This is not what the client gets, so not what the client-side script has to
operate on.

Then it is so.
and when I loop throught the elements in my form, dgrList is not one of
them(yes it is between the form tags).
Only form controls are part of the `elements' collection. A table is no
form control. And it should be `.rows[0]'.
My question, is there a way to reference the created table via javascipt?
There is. My first educated guess would be
document.getElementById("dgrList") -- with proper feature test --, but you
should really look at the generated source code, not the generating one.

Note Thomas' reply, some (most?) browsers don't provide a click method
for all elements even though they support the onclick attribute.

If rowRef is a reference to a row, then rowRef.click() may 'work' in
some browsers (e.g. IE), but not others (e.g. Firefox). You need to use
createEvent to attach the event so you can click on it.
<script type="text/javascript">

function clickOn(id)
{
var el;
if ( document.getElementById
&& (el = document.getElementById(id))){

// Create an event object
if ( document.createEvent ){
var eventObj = document.createEvent("MouseEvent");

// Initialise properties
eventObj.initMouseEvent("click", true, true, window,
0, 0, 0, 0, 0, false, false, false, false, 0, null);

// Run the event
if (el.dispatchEvent) el.dispatchEvent(eventObj);

} else if (el.click) {
el.click();
}
}
}

function sayHi(){alert('hi');}

</script>

<input type="button" value="Attach click"
onclick="clickOn('tr01');">

<table border="1">
<tr id="tr01" onclick="sayHi();">
<td>Click the button to fire the onclick event</td>
</tr>
</table>

That should be: dispatch the event to run the onclick handler.
