adding class on a random list item

jquery, random

Solution

var random = Math.floor(Math.random() * 1000);

var $li = $("#gallery li");
$li.eq(random % $li.length).addClass("on");

Problem

I have an unordered list with list items. I have a class called 'active', which I want randomly be added on a list item. I now have this: ``` // I want this class added on a random list item $("#gallery li:first-child").addClass("on"); ``` Math.random?
