I’m one of the organizers of the Mobile Widget Camp on May 2. The free event is taking place at Pakhuis de Zwijger, Amsterdam. Daniel Appelquist (Vodafone Betavine), Peter-Paul Koch (Quirksmode), and Elliot Kember (Carsonified) are among the speakers in the morning, so you’re guaranteed to get a great introduction to Vodafone/Opera widgets. Beside these speakers there will be hands-on workshops and time to code your own mobile widgets. Anyone with basic HTML, CSS and Javascript knowledge can make a mobile widget, so make sure to come and help will be available from experts to help you coding. Read more about Mobile Widget Camp on the website.

Here is a nice little Javascript function to load some Javascript libraries:

function includeLibs()
{
var libs = [{object: 'Prototype', src: 'http://www.mobypicture.com/slideshow/prototype.js'}, {object: 'Lightbox', src: 'http://www.mobypicture.com/slideshow/lightbox.js'}];
for (var k = 0; k < libs.length; k++)
{
try
{
var obj = eval(libs[k].object);
}
catch (err)
{
var obj = false;
}
if (obj == false)
{
var newjs=document.createElement('script');
newjs.type='text/javascript';
newjs.src=libs[k].src;
document.getElementsByTagName('head')[0].appendChild(newjs);
}
}
}
This is particularly useful if you’re writing a widget that requires external libraries but the user might already have them loaded, such as Prototype.
