If I understand you right, try this:
<html>
<head>
<title>Form</title>
<script language="JavaScript">
function submitForm(formName) {
eval("document.forms." + formName + ".submit();");
}
</script>
</head>
<body onload="submitForm('myForm1')">
<form name="myForm1" action="/formprocessor.php" method="POST">
<input type="text" name="textField1" value="Yo!"><br>
^^^^^^^^^^^^^^^This should submit automatically.
</form>
</body>
</html>
Hope this helps!
