not really sure what you mean but what I tend to do is include the html for all "pop-ups" in the original page markup and simply toggle display to none or block with whatever JQuery event you want, such as 

$("button#popupbtn").click(function(){$("#hiddencontent").css("display", "block")});


This way you dont have to download the markup every time as you would if you were using Ajax and you get the SEO benefits of whatever is in the extra markup too.

If you did choose to use Ajax you could also prevent repeated downloading by caching the results (basically saving a local copy to reuse) after they have been downloaded, but this wouldn't really be necessary because the 1st method is easier and better for SEO

put an html (scripted) menu in a separate file
I have come across this term fairly often, where full/associate/assistant professors are referred to by the term ‘clinical’. Given that their departments had nothing to do with medicine, I thought the term referred to the second meaning of clinical:


  scientifically detached; strictly objective


Is this interpretation correct? If yes, isn’t such a branding offensive?
