Hi,
The form must be on the page that has the button. Here is a simple example
(watch for line breaks in the M_findObj):
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript">
<!--
// cross platform/browser object finder
// you could probably use a simpler one just for your form
function MM_findObj(n, d) { file://v3.0
var p,i,x; if(!d) d=document;
if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++)
x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++)
x=MM_findObj(n,d.layers[i].document); return x;
}
function formSubmit(formaction) {
// form name could be a parameter too
formObj = MM_findObj('test');
formObj.action = formaction;
alert(formObj.action);
formObj.submit();
}
file://-->
</script>
</head>
<body bgcolor="#FFFFFF">
<form name="test" method="post" action="">
<p>
<input type="text" name="textfield">
<br>
</p>
<p>
<input type="text" name="textfield2">
</p>
<p>
<input type="button" name="Button1" value="Button"
onClick="formSubmit('servlet/TheFirstServlet');">
<input type="button" name="Button2" value="Button"
onClick="formSubmit('servlet/TheSecondServlet');">
</p>
</form>
</body>
</html>
