One click on a form submits twice!

[Ken Adams]

Basically I have a form that looks something like the following: The form is
contained in the file subscriptAdd.jsp so I want to submit the form to
itself and do some jsp validation after it's submitted, but for some reason
I noticed that two request are being make on each click. Any suggestions.
Thanks

<form name="add" action="<%= response.encodeURL("subscriptAdd.jsp") %>"
method="POST" onsubmit="return checker()">

<input type="submit" value="Submit">

</form>

What does checker() do? Odds are that's the problem. What does
subscriptAdd.jps do? Mind you, you haven't posted enough of your code
for anyone to do more than guess the answer. Thinking about it, don't
post your code here - provide a URL instead.

saying that it looks "something like the following" and then including a
tiny snippet of code isn't going to be much for people trying to help you
(we'll have to ask "is this the actual code? how "like" the real thing is
the above? Is there something else that could be causing the problem?
Whats in 'checker()'?). A working link to your web page with the form would
be much better.

Odds are your problem is the part:
onsubmit="return checker()"

instead you probably want:
onsubmit="return checker(); return false"

That might fix it up

URL?

<form name="add" action="<%= response.encodeURL("subscriptAdd.jsp") %>"
method="POST" onsubmit="return checker()">

You should generally include the output HTML, not your JSP when asking
about an HTML related question. Though, in this case it appears as
though the output will be action="subscriptAdd.jsp".

There is no reason why that code would make anything submit twice,
unless the JavaScript function has something to do with it. Check that
function checker() isn't doing any unnecessary form submissions. Other
than that, it's most likely an error with your JSP back end coding.

jsp form submtting twice

I am facing the same issue. My jsp page is like this.

<form method="post" name="MyForm" action="/servlet/ibs.servlets.MyServlet">


<TR id="buttons"><td align="right" colspan=2 class="clsdetsub"><A class=clsinfo href="javascript:yesPage()">Confirm</A>

function yesPage()
{
var tb1 = document.getElementById('buttons');
var tb2 = document.getElementById('aftersubmit');
tb1.style.visibility = "hidden";
tb2.style.visibility = "visible";
document.MyForm.submit();
};

Sometimes click on Confirm, submits the form twice. How it is happening? Wat is the solution to resolve this? Pls help.....
