You want to create a button or a navigation list entry where you want to open an URL in a new browser window?
With plain HTML you would normally just write
<a href="http://url/" target="_blank">
but how to specify the target=”_blank” in Oracle APEX, where you just have the property “URL Target” which just allows you to enter the URL?
You can use the same technique as for SQL injection. Just write
into the “URL Target” property. APEX will add the closing quote after _blank for you, because it thinks the URL ends there. That way APEX generates a valid a href with a target for you.
