Making an anchor with JavaScript called from backing bean

Question

I know it will sound crazy, but I'm looking for a way to make an anchor (like <a href="#someId"> ) that could be called from a backing bean method using JavaScript. For some reasons I need to make it this way, with a commandButton that is set with ajax="false" .

I'm trying something like this:

RequestContext.getCurrentInstance().execute("JAVASCRIPT THAT FOCUSES MY PAGE ON A HTML COMPONENT GIVEN ITS ID");

The idea is that even without ajax I could render my page showing it back to where it was.

Any ideas? It might be a simple JavaScript command, but I'm not really into JavaScript and I didn't find any simple solution that works...

Answer 1

Simply set location 's hash fragment.

In JavaScript:

location.hash = "someId";

In JSF/PrimeFaces (if really necessary):

RequestContext.getCurrentInstance().execute("location.hash='someId'");

The alternative would be to send a redirect:

externalContext.redirect(request.getRequestURI() + "#someId");
