Activated on Page Load?

[AnilGupte]

$(document).ready(function() {
ifvisible.setIdleDuration(30);
ifvisible.idle(function(){
var msg = 'No activity detected in the last 15 seconds.';
if (auth == "true"){
msg += "
You will be logged out in 15 seconds.";
}
alert("WTF");
Message('' + msg + '');
function showmsg() {
msg = '
You will be logged out in ' + count + ' seconds.';
document.getElementById("timer").innerHTML = msg;
count=count-1;
if (count <= 0) {
clearInterval(counter);
return;
}
}
var count=15;
var counter=setInterval(showmsg, 1000);
window.location.href = "./media.php";
});
})

The above code executes on page load and it shouldn't. It almost seems like .idle is set to true by default so it executes by default.
