Hello,
I have a form with two select tags. I want the options for the second to be
dependent on the option chosen for the first. What is the best way to
accomplish this? If java script is the answer, how do I obtain the value of
the option chosen in the first select (I'm new to web apps)?
What I've tried to do is create the options for the second select in the
form bean given the value of the first, but of course, the set method for
the property associated with the first select is not called until the form
is submitted.
<html:form action="/Go" name="GoForm" type="my.GoForm">
<bean:message key="app.select.category"/>
<html:select property="category">
<html:options name="GoForm" property="categoryCollection"/>
</html:select>
<bean:message key="app.select.subcategory"/>
<html:select property="subcategory">
<html:options name="GoForm" property="subcategoryCollection"/>
</html:select>
...
</html:form>
Thanks for helping,
Kelly
