Why is page refresh triggering .keyup()?
<p>I have this function:</p>

<pre><code>$('.PhoneNumbers').on('keyup focusout', $('input:text[name^="Customers[0].PhoneNumbers"]'), function (e) {
    phoneRadioBtns(e);
});
</code></pre>

<p>The problem is that when I refresh the page it triggers the keyup event and it executes the function, which is not the desired result.  Does anyone know how to correct this?</p>
