E-Books for you

We can use JBrowser to check
for certain quirks in browsers. In this example, we check that the browser is happy to
deal with popups:
$browser =& JBrowser::getInstance();
if ($browser->hasQuirk('avoid_popup_windows'))
{
// the browser does not like popups
}
Generally, all browsers, except mobile browsers and old browsers, will deal
with popups.

This is a list of the different quirks that we can check for using JBrowser:
avoid_popup_windows
break_disposition_filename
break_disposition_header
broken_multipart_form
cache_same_url
cache_ssl_downloads
double_linebreak_textarea
empty_file_input_value
must_cache_forms
no_filename_spaces
no_hidden_overflow_tables
ow_gui_1.3
png_transparency
scroll_tds
scrollbar_in_way
windowed_controls
Both the quirks and features are hard-coded in Joomla!; they are not retrieved from
the browser. This means that JBrowser will not detect popup blockers or other
unexpected settings.
