how could I randomize a jQuery tooltip

I am going to use on of the tooltip plugins listed in this question: jquery tooltip, but on click instead 开发者_运维问答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?

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

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

$('.withTooltip').click(function(){
  $("#tooltip").text(messages[Math.round(Math.random() * 3)]).show();
});

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;
}
