[Resolved] Form focus help needed (combined PHP and Javascript)

NetRoam

Hey all!

I have a slight problem ... it isn't a very big problem, but enough for make me irritated about it being there 🙂

I have a PHP-file which includes 3 different pages. An introduction-page, a login-page and a "create profile" page.

The thing is that I want to have a form focus on the first field at both the login-page and the "create profile" page, but the introduction-page doesn't have any forms so therefore I don't need a form focus there.

I tried using the following code:

<body onload="document.forms[0].b_username.focus();">

Which also works fine on the login-page and the "create profile" page, but the browser gives me an error on the introduction-page withthis message:

Error: 'document.forms.0.b_username' is null or not an object

Anyone have any idea how I can make it easier so I will remain the form focus on 2 pages but remove it on the 3rd?

Thanx!

The quick and dirty workaround for this would be to have a form in the page that it's giving the error, and just have a hidden field called the same name. That way, it'd focus on it, and you wouldn't even know. Quite simple really!

Alternatively, you can create a JavaScript function to check if there is such an element, if there is, then you would want to focus on that.

Hope it helps,
Kevin

I'm just extremely lousy at Javascript so I don't know how to create such a function to check if there's a form on the page with xxx value, but thank you for your quick reply

Anyone willing to help with that?

<body
<?
if (isset($page) && $page != "")
    {
    echo " onload='document.forms[0].b_username.focus();'";
    }
?>

would be to use

if ( document.forms[0] ) document.forms[0].b_username.focus();

Thank you for both your answers!

Unfortunately I won't be able to test it until monday when I return to work, but I'll let you know then if it worked or not. 🙂 Thanx again!
