'document.getElementsByTagName(...).1' is null or not an object error

[ERuiz]

Hello all,

I am getting this error message everytime I access a page which has a small javascript snippet. The thing is that the page is actually working properyly, but this error message is really driving me nuts and makes the page look unprofessional.

Here is the javascript snippet in the page, which is causing the error message:

[code]
<script language="JavaScript" type="text/javascript">
function updatehours ( selectedtype )
{
  document.logbook.userid.value = selectedtype ;
  document.logbook.submit() ;
}
</script>

<form name="logbook" action="updatehours.php" method="post">
<td valign="top" rowspan="3" STYLE="text-align: left; font-weight: bold; padding-left: 6px;"><a href="javascript:updatehours('<?php echo $userid; ?>')" target="_self" >UPDATE TOTAL HOURS</a></td>
<input type="hidden" name="userid" />
</form>[/code]

This little script, makes a regular link act like a form button when a user clicks it. What is causing this error message?

BTW, the error message only appears on IE.

Regards,

are you using getElementsByTagName anywhere in your code?

and i would suggest that you change the way that you point to elements on your page. Use the id identifier, it is faster. give your elements unique id's then reference them like
document.getElementBy('id').submit() etc

Hi emehrkay,

Nop, getElementsByTagName is not being used anywhere on the page.

Sorry for my ignorance, but how would I implement the ID identifier on the script I posted above?

Thanks,

ERuiz

<form id="somethingUnique">
<input id="somethingUnique2 />

get[b]Element[/b]ByTagName()  , not the plural

--if you are not using 'document.getElementsByTagName' then what is the error message you are getting?
