Hi Rob,
I agree, popup blockers are certainly a concern. However, most browsers
appear to have a very focused definition of what constitutes a popup window.
To my, albeit limited, knowledge, programmatically opening a new window in
response to a user click is not blocked by the popup blockers provided by
Mozilla, Safari, and IE 8 (although the default setting can be changed to
block popups initiated by a user click, and this includes changing the
behavior of the target attribute, too):
tinyurl.com/2d3pq76
tinyurl.com/243fku8
tinyurl.com/38q2ua3
tinyurl.com/2co63x3
(key phrase on this page is "Google Chrome blocks popups from *automatically
* appearing", emphasis added.)
<http://support.mozilla.com/en-US/kb/pop-up+blocker#Is_the_pop_up_shown_after_a_mouse_click_or_a_key_press_>Popups
that are sneaky (delayed response to click, mouse gesture, open immediately
when you view the page, etc.) are much more likely to be blocked by various
browsers, and the popup blocker tests I'm familiar with focus on these
specific types of nefarious activity:
tinyurl.com/gwsbu
So, most of the time you can use window.open() to create a new window, stay
true to the DTD you're using DOM scripting to manipulate, and avoid issues
due to popup blockers. However, as is always the case, testing your
particular implementation across the range of browsers representative of
your intended audience is of paramount importance (i.e., don't blame me if
you have issues because you didn't test your particular use cases ;)
