Question

I am testing the following code with two jQuery versions: 1.5.1 and 1.7.2

$(':radio').change(function(){alert(1)});

It works in the old jQuery and not in the new one. Why do I have to use .click() in the new version?

Browser: Chrome 18

Answer 1

It works for me:

<input type="radio" name="foo" value="1" checked /> Radio 1 <br/>
<input type="radio" name="foo" value="2"/> Radio 2 <br/>

<script>
$(function() {
    $(':radio').change(function() {
        alert(this.value);
    });​
});
</script>
