Question: I am going to use on of the tooltip plugins listed in this question: [jquery tooltip, but on click instead of hover](https://stackoverflow.com/questions/1313321/jquery-tooltip-but-on-click-instead-of-hover)

How would I also setup a tooltip that randomized the text shown. For instance if you click a link you could be shown one of three possible messages:

Message 1
Message 2
Message 3

ideas?

Answer: 
You usually have an array of messages and then generate a random index onclick. 

something like

```
 var messageArray = ["message 1", "message 2", "message 3"];
 var randomNum = Math.floor(Math.random()*messageArray.size);
 var myMessage = messageArray[randomNum];

```

or something like that. refactor to use ajax/your db if you need to
Using a very small function from PHP.js: <http://phpjs.org/functions/rand:498>

I do it like so:

```
var messages = [
    'Message 1',
    'Message 2',
    'Message 3'
];

var random_number = rand(0, messages.length);
$("#tooltip").text(messages[random_number]);

// PHP.js rand() function.

function rand (min, max) {
    var argc = arguments.length;
    if (argc === 0) {
        min = 0;
        max = 2147483647;
    } else if (argc === 1) {
        throw new Error('Warning: rand() expects exactly 2 parameters, 1 given');
    }
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

```
