Browser-friendly popup windows that don't get blocked (for a help window) - jquery plugin?

I've been tasked with making our help section open in a new window which isn't blocked by any of the major browsers' anti popup behaviour. My spec is 'to make it like the one on the salesforce website'. haha. (The salesforce site is login only i'm afraid so i can't even show you it.)

Anyway, before i tried to reverse engineer that site i thought i'd ask here, thinking that the开发者_如何学运维re may be a jquery plugin for this, for example, and that generally this problem would have been solved already by smarter people than me.

Any advice welcome - max

Take a look at the jQuery UI dialog, it comes in many flavours and you can put whatever you want in it, if you absolutely have to you can even use it as an iframe pop-up.

The dialog works by showing and hiding a div which is positioned on top over all other elements, there is little chance a pop-up blocker will cause any problems, but it does require javascript to be turned on. If javascript was turned off you'd have to use a bit of graceful degradation to maintain it's usability.
