Hi There,
Why dont you change the button back to a submit and then add a
onSubmit='return validation();' to you form ?
Thats what we do
Eg.
<Script>
function valid () {
if (document.form.val.value.length < 1) {
alert("Please enter a value");
return false;
}
return true;
}
</Script>
<form onSubmit="return valid();">
<table>
<tr>
<td>
<input type="text" name="val">
</td>
<td>
<input type="submit">
</td>
</tr>
</table>
</form>
Thanks
Pete

Subject: JSP question
Hello All,
I am pulling my hair on this problem, and since there are many Java experts
on this mailing list, I hope someone can help me on this.
I have a simple servlet that calls a JSP page where the user can enter a
search value. When the user clicks on the submit button, the search value
will be passed back to the servlet for processing and display. All these
are running on Tomcat 4.1.24.
Everything works fine until I added the form validation routine in the JSP
page. Initially, my input button type was "submit". I changed it to
"button" and leave the submission to the form validation routine which is in
JavaScript. Now, when I click on the button, I get the error message of:
"Object doesn't support this property or method"
at the line of code:
document.form1.submit();
Does anyone know why? The following is code of the JSP page:
//code begin----------------------------------------------
<html>
<head>
<title>blah blah blah</title>
<link rel=stylesheet href="css/standard.css" type="text/css">
</head>
<body>
<form name="form1" method="POST" action="">
<center>
<b>Please enter ANI for query:</b><br><br>
<table>
<tr>
<td>ANI</td>
<td><input type=text name="ani"></TD>
</tr>
<tr>
<td></td>
<td COLSPAN="2">
<input type="button" name="submit" value="Submit"
onclick="javascript:validateForm();">
<input type="Reset" name="cmdReset" value="Reset"></td>
</tr>
</table>
</center>
<script LANGUAGE="JavaScript">
function validateForm(){
if(document.form1.ani.value == ""){
alert("Please enter an ANI");
return;
}
document.form1.submit(); //This line generated error. The
.submit() method is not supported.
}
</script>
</form>
<%@ include file="footer.jsp"%>
</body>
</html>
//code end------------------------------------------------
Any help will be very much appreciated.
