Java with forms issues

1: Server-side I would use servlet/jsp, php or perl (in that priority)... whatever the server could offer.
2: You should look into the element/event model for javascript, but remember that there are significant differences in the way the different browsers have implemented this. As I have gathered only IE covers the lot.

What is done here is that the submit button is supplied with an onclick handler that checks the form elements. If the check fails the onclick handler returns FALSE, which again stops the form from being submitted

A GOOD book: O'Reilleys "JavaScipt - The Definitive Guide by David Flanagan"

Btw. here is the code i fished out from the website, It looks like the verifier
... notice the 4-letter-word filter :cool:

The x-parameter here is the form that is being validated.

function v(x) {
var y = x.s_email; var z = x.s_name; var z1 = x.s_maiden_name;
y.value = y.value.toUpperCase(); z.value = z.value.toUpperCase();
z1.value = z1.value.toUpperCase(); y.value = q('WWW.','',y.value);
y.value = p(y.value);
if (z.value.indexOf(',') != -1) {
var cm = z.value.indexOf(',');
z.value = z.value.substr(cm + 1, z.value.length - 1) + ' ' +
z.value.substr(0, cm);
}
for (var i = 0; i < 10; i++) {
z.value = q(i.toString(), '', z.value);
}
for (var i = 0; i < 10; i++) {
z1.value = q(i.toString(), '', z1.value);
}
z.value = q(':', '', z.value); z.value = q('>', '', z.value);
