How do I randomly check a new radio button after a certain time?
I like to archive the effect that the checked radio button automaticially change every 5 seconds. Thank you!
<input type="radio" id="mc" name="radiobutton" value="Mastercard" checked>
<label for="mc"> Mastercard</label><br>
<input type="radio" id="vi" name="radiobutton" value="Visa">
<label for="vi"> Visa</label><br>
<input type="radio" id="ae" name="radiobutton" value="AmericanExpress">
<label for="ae"> American Express</label>
You can use setInterval
var $inputs = $("input[type=radio]");
setInterval(function() {
var random = Math.floor(Math.random() * $inputs.length);
$inputs.each(function(i, node) {
node.checked = (i === random);
});
}, 5000); // 5000 = 5 seconds
