Chapter 6
The other two message levels function similarly, but warning will create a yellow
box and status will create a grey box (colors, of course, are determined by the CSS).
If you are using this module, the Drupal.messages.set() function is a good tool for
providing user notifications.
Adding links
There are many useful functions in the JavaScript theming library, but to save space
(and cover more ground regarding theming), we will cover only one more. This
function is Drupal.l(), and it is the main function used for creating links.
Those familiar with PHP programming for Drupal, will find it unsurprising that
Drupal.l() provides the same functionality as the Drupal PHP l() function. It is
typically called in this way:
Drupal.l(text, url);
Here, text is the text that will be linked and url is the relative URL of a Drupal
resource. For example, we could create a link to the fifth node in our system like this:
Drupal.l('Node 5', 'node/5');
This would return a string of HTML that looked like this:
Node 5
Note that the link for the base path on my system has been adjusted. It has turned
node/5 into /drupal/node/5.
There is an optional third parameter which can contain additional options. These
options are all documented at http://api.drupal.org/api/function/l/6. For
example, if we wanted to use an absolute URL, instead of a relative one, we could set
the absolute property to true:
Drupal.l('Drupal', 'http://drupal.org', {'absolute':true});
This would result in a link pointing to http://drupal.org, instead of a relative link
to our own server.
The JavaScript theming module provides some useful tools for extending the
JavaScript capabilities of your Drupal 6 system.
Next up, we are going to work on another project. In this project, we will implement
a simple template system.
