set form action - Javascript

Andrew Poulos

I have a FORM tag that looks like this:

<form name="form1" id="form1" method="post" action="go.php">

I can leave off the ACTION attribute and have javascript add it on load,
for example:

<script type="text/javascript">
window.onload = function() {
var frm = document.getElementById("score");
frm.action = "go.php";
frm.submit();
}
</script>
</head>

<body>
<form name="frm" id="frm" method="post">

I tried it and it seems to work but I'm uncertain if it's the "best" way
to add an attribute.

Neither above nor below I can see an element with id "score".
frm.action = "go.php";
frm.submit();
}
</script>
</head>

<body>
<form name="frm" id="frm" method="post">

It depends on the criteria as to what you regard as best, if you want to
cover old browsers like Netscape 4 then it is better to use
var frm = document.forms.frm;
frm.action = "go.php";

The action attribute is required, even if it's empty (though as you
point out, most browsers will not get too upset about it).
