jQuery

This example is a two-for-one deal! I'm going to demonstrate how to

1. dynamically populate a webform select list on page load
2. dynamically populate a webform select list based upon the value chosen in another webform select list

We use menu block a lot to create sidebar menus with specific depths, starting points, etc. The following snippet shows how we can use jQuery to turn a normal <h2> tag into a link. The link's destination will be the same as the first child link.

The following snippet is one way to determine if a jQuery plugin is loaded an available. There are probably other ways to achieve the same behavior, however this one never seems to fail me.

if (jQuery().jcarousel) {
  // The plugin is here, do something with it.
  $('.jcarousel-enabled').jcarousel();
}

$(document).ready(function() {
  $("a[href^='http']").not("[href*='mysite.com']").attr('target','_blank');
});

... and to match two urls/domains/whatever:

$(document).ready(function() {
  $("a[href^='http']").not("[href*='mysite.com'],[href*='mysite2.com']").attr('target','_blank');
});
