|url||The URL (website address) to link to.|
|target||This is the target area to open the URL in.|
This will open the specified URL on the browser of the chosen
target device, or, if you are using the HTML5 module, in the
currently open browser. The "target" parameter that you specify is
open() method, and you should be aware that all but
'_self' may result in the browser blocking, or asking the user if
they wish to allow it.
Valid targets are:
"_self": Opens the linked document in the same frame as it was clicked (this is default).
"_blank": Opens the linked document in a new window or tab (this will not work if pop-ups are being blocked by the user, in which case you can use the clickable_* functions instead).
"_parent": Opens the linked document in the parent frame.
"_top": Opens the linked document in the full body of the window.
NOTE: On the Windows 8 (JS) target platform, this
function will work, but additional parameters will be
ignored and the default browser will be launched with the given
url_open_ext( 'http://yoyogames.com', '_blank');
This would open the YoYo Games homepage in a new window.
