json request choose randomly

[hamburger]

Hello,
I would like to choose randomly some arrays out of my json.request (by
parameter)
How can i do this?

var number_to_choose = 3;

var request = new Request.JSON({
url: path + 'recent.json',
onComplete: function(jsonObj) {
//var
rand = $random(0, jsonObj.lending_actions.length-1);
//addText(jsonObj.lending_actions[rand]);
addText(jsonObj.lending_actions);
}
}).send();

var addText = function(addArchiv) {

zufall =$random(0,99);
var name = new Element('h2', {'html': 'Hallo'});

addArchiv.each(function(item, index) {
if(index==zufall)
{
var liste = new Element('ul', {'class': 'recentlist'}).inject
(name);
var el = new Element('li', {'html': 'index:'+index+' item:
'+item.id+'&nbsp;<a href="'+item.date+'"
class="loadMe">'+item.loan.use}).inject(liste);
}
});

name.inject(sidebar);

};

Well, since lending actions is an array, you can start there:

var number_to_choose = 3;
var request = new Request.JSON({
url: path + 'recent.json',
onComplete: function(jsonObj) {

var notimes = 3;
// I could be wrong about this one, but you generally want a loop that
does this X times, right?
notimes.each(function(time){
var RandEntry = jsonObj.lending_actions.getRandom()
// do stuff with the entry... make sure you check you didnt get it
already, so you dont duplicate...
})
