Hi,
I am sorry I don't get it.
How and when to set the JS variable?
Like this:
mySubmitButton.add(new AjaxEventBehavior("onclick") {
@Override
protected void onEvent(AjaxRequestTarget target) {
AjaxRequestAttributes ajaxRequestAttributes = new
AjaxRequestAttributes();
CharSequence dynamicExtraParameters = "var enableEvent =
false;";
ajaxRequestAttributes.getDynamicExtraParameters().add(dynamicExtraParameters)
pageExitWarningBehavior.updateAjaxAttributes(ajaxRequestAttributes);
}
});
And which onBeforeRender, the one of the TextField?
Best Regards
Daniela
