How to get random element in jquery?

Question

How can I return a random element in jQuery by doing something like $(.class).random.click()?

So, if .class had 10 links, it would randomly

Answer 1

var rand = Math.floor(Math.random()*10);

$('.class').eq(rand).click();

Math.random() gets you a pseudo-random number between 0 and 1, so multiplying it by 10 and rounding it down gets you 0 to 9. .eq() is 0 indexed, so this will get you a random jQuery element out of the 10 you have.
