23 Sep 08 JavaScript List Utility

Here's a little something I was working on today. The goal was to model an HTML unordered list in JavaScript so I could easily add/remove and display elements. I haven't gotten around to actually writing all of the display methods because I haven't exactly figured out how I want to use it yet.

PS: I kinda re-remembered the toString method on this one.

PPS: Requires prototype

Example Usage:

set up the list

list1 = new List();
list1.add('a');
list1.add('b');
 
list2 = new List();
list2.add('b1!');
list2.add('b2!');
 
// nest away!
list1.add(list2);
list1.add('c');
list1.add('d');

li data

alert(list1.get_at(1).data);

remove li

list1.remove(4);

alert the list

alert(list1);

BAM!

Download the code!
