Your best bet for stopping the user from submitting a form with JavaScript
is to handle it in the form tags onsubmit attribute.
Here's an example from a recent app I'm working on:
I needed a way to make sure that users entered a minimum of 3 (or some
configurable value) characters when performing a search. The problem is
that it can be 3 characters from any combination of 3 fields.
<html:form action="/manageUsers"
onsubmit="return doMyValidation(this)"
focus="view.registration.security.userName">
...and at the bottom of the page I do this...
<script language="JavaScript"/>
function doMyValidation(form){
u =
form.elements['view.registration.security.userName'].value.length;
f =
form.elements['view.registration.personal.firstName'].value.length;
l =
form.elements['view.registration.personal.lastName'].value.length;
if (u + f + l < <bean:message
key="validation.min.search.chars"/>){
alert('<c:out value="${msg}"/>');
return false;
}
return validateSearchForm(form);
}
</script>
<html:javascript formName="searchForm"
dynamicJavascript="true"
staticJavascript="true"/>
...what that does is allow me to insert my own custom validation and, if
that passes, then the validator-generated one is run.
