问题
I have a column in a database table that contains several urls and I was wondering what is the best way to get these urls from the database table into a javascript function.
Example code of how to approach this would be much appreciated.
Thanks.

If you can get the URLs into page items via PL/SQL code then you can access the page item values from Javascript like this:
url1 = $v('P1_URL1');
url2 = $v('P1_URL2');
For example, you could have an on-load PL/SQL process like:
select url1, url2
into :p1_url1, :p1_url2
from my_urls
where ...;
To put several URLs into an array you could use the PL/JSON library - see this example. Again, this would be PL/SQL code to put the JSON array into a page item which you can then access from Javascript using v$(). Or you could use AJAX as descrobed here.
