Providing client side validations after a wizard step is finished
You can configure a user-defined javascript function, which will be called when a wizard step is completed but before next step is loaded. You need to write you own functionality in some javascript function and specify the name of function as the value for the attribute "afterJS" while defining the action for that particular step. The next step will only be displayed if the specified function returns "true".
For example:
In <*-actions>.xml
<action name="setClassificationAttributesWizStep" afterJS ="
validateStep">
<command windowType="wizard_step"/>
</action>
In any JSP page or Javascript file accessible to wizard
<script type="text/javascript">
function validateStep() {
...
...
return true;
}
</script>
