java script not working after page reload

I have a java script running in create page that calculate risks depending upon selected options of some select lists (these are the risk questions). All questions are mandatory, so user cannot escape without selecting any option in any those select lists. But the problem is, when someone does not enter value in any select list or in any other mandatory field and submits the page, the code stops working properly. I found the reason is that on page reload global variables are getting their initial values which is causing this. But how to either keep the final values of these variable while page is being reloaded or setting the initial options to all select lists?

Any help will be greatly appreciated.

Hi Indranil,

You probably load the script through AJS.toInit ... but you fail to load the script again when the page's content changes(e.g. page submits). You probably need to add the code on 

JIRA.Events.NEW_CONTENT_ADDED

event. For more info see this guide

Peter
