JQuery: get element ids as array

I needed to get the collection of IDs in an unordered list in order to use this to update the database. The code below worked nicely:

var IDs = $("#ullist li")
               .map(function () { return this.id; })
               .get();

I’ll explain briefly by line:

1. Get the li elements of my ul.
2. map traverses each element returned and in this case I return the ID of each element.
3. get returns a JSON array. It can be used with full elements etc. In this instance as I’ve used the map it simply returns an array of IDs.
