You can have a hidden field say hdSubmitFlag in the page whose value is
defaulted to "N". Your javascript can set this field to "Y" and call
submit(). this_onBeforeLoad() of the page you can check the value of this
field to distinguish between first-time request for the page and a submit.
(Your button_onWebEvent() code would go here)
You can't rely on getDisplayFieldValue("hdSubmitFlag") since it will carry
"session-bled value" on first-time invocation of the page. getWebVar() with
check for null should work.
