USING INDEX NUMBERS

This example demonstrates how jQuery gives an index number to each of the elements in the jQuery selection.

The :lt() and :gt() selectors and the .eq() method are used to find elements based on their index numbers.

For each of the matching elements, the value of the class attributes are changed.

1. The :lt() selector is used in the selector to pick list items with an index number less than 2. It removes the value hot from their class attribute.

2. The .eq() method selects the first item (using the number 0 because the index numbers start at zero). It adds the value of complete to the class attribute.
