When developing web applications, select-boxes are usually involved in the UI. I’ve put together a custom JavaScript class to handle things like removing, adding and selecting elements. By the way, Matt Kruse has a bunch of nice JavaScript libraries!

Example:

var e=new DynamicSelect('MySelect');
e.removeAll();
e.append('Entry 1','');
e.append('Entry 2','');
e.selectAll();
e.unselectAll();
e.select('Entry 2');
e.toggleAll();
if(e.contains('Entry 1')){
alert('We got Entry 1!');
}
if(e.indexOf('Entry 2'!=-1)){
alert('We got Entry 2!');
}
e.insert('Entry 0','',0);
e.select('Entry 2');
e.removeSelected();
e.remove(0);
alert('Original HTML element name: '+e.parent().name);

The methods are documented in the source file, if you want to know more about them.
