This is a useful jQuery Script that removes duplicates within an element such as a list. It simply cycles through an element and removes anything previously ‘seen’.
Let’s take a list of Cities as an example:-
- London (is removed as duplicate)
In this example we are cycling through a standard unordered list and removing duplicates, but you are recommended to give the list / element a class as otherwise you could be targeting other elements on the page where you want duplicates.
