Selecting a random li element - JQuery

Question

I was wondering if there is a way to have JQuery randomly select a `li` inside a `ul` tag. Example: ```

1
2
3
4

``` So here is what would happen, lets have a click event so, `$("ul li:last").trigger('click');` but notice how it has `:last`, how could I specify whether it selects the second, third, or even the fourth `li` based in the tree randomly. UPDATE: I notice other suggested using math, what if I have a `ul li` list that is populated by MySQL, I wouldn't know how many `li` there would be.

Accepted Answer

Use

```
Math.floor( (Math.random() * $('ul li').length) + 1 );
```

This gives you a number between 1 and the number of `li`, then use the `:nth-child()` selector.
