Just from the top of my head, if you define a different page/tile for result type INPUT (validation error) then you can put your javascript there.

For example :

<action name="getX_1" method="getX" class="com.x.X">
<result type="tiles" name="success">getX_1_page</result>
</action>



<action name="getX_2" method="getX_2" class="com.x.X">
<result type="tiles" name="success">getX_2</result>
<result type="tiles" name="input" >getX_1_page_error</result>
</action>

Now the JSP referered to by getX_1_page_error can have the Javascript. You will not need to check for error because you go to that page only when you have error.

getX_1_page and getX_1_page_error are same except for the fact that getX_1_page_error has Javascript to deal with the errors.

Hope this helps
