jQuery, is there a way to set anchor in URL after form submitting?

For example, I have tabulators (bootstrap, tabpanel) which changes the url, adding #tab1, #tab2, ... as Im clicking on them. Lets say I do a submit from #tab1, and want to jump to #tab2, how to do that? All I have is:

.
.
.
$(formObj).submit();
return false;

the action of form is empty (<form method="post">)
