Question

Suppose if my HTML is like below

<select>
         <option value="1">option 1</option>
         <option value="2">option 2</option>
         <option value="3">option 3</option>
         <option value="4">option 4</option>
</select>

How can I select one random answer from all the items.

Answer 1

var $sel = $("select > option");
var $opt = $sel.eq(Math.floor(Math.random() * $sel.length));
alert($opt.text());  
// now do stuff with $opt
