I am trying to fix error- object does not exist- I want it possible to
allow object not to exist.
I am writing a script on a page that may or may not include a login
form. For example-after a visitor logs in, the login form is no longer
on the page, but other content is still there.
I want to bring focus to the login form using the onLoad in the body
tag.....but if the login form does not exist, I do not want to perform
this function.
The following code works fine for focusing the cursor on to the login
form.
(code)
<html>
<head>
<title>
Testing Javascript
</title>
<script type="text/javascript">
<!--
function addcursor ()
{
if (document.login) {
document.login.username.focus();
}
}
//-->
</script>
</head>
<body OnLoad ="addcursor()">
<form name="login" id="login" action="" method="post">
<input type = "text" name="username" id="username" />
<input type="password" name="password" />
</form>
</body>
</html>
(end code)
But if you remove the form in the body section from the code, an error
"object does not exist or is null" results.
I am looking for a way to avoid this error.
Any suggestions?
