I'm having a problem with trying to find out whether the parent element does not have the element with the specific class like so:
// after clicking on the button inside of the form - get the instance of the parent form
var par = $(this).parent('form');
if(!par.has('warn')) {
// do something
}
Any idea how to achievie it - as has() doesn't seem to find it
.has doesn't return a boolean, so if there are no matches the returned object has 0 members.

<div><input id="thebutton" type="button" value="Click Me" /></div>
<div class="test">test div</div>

$(document).ready(function() {
$('#thebutton').click(function() {
var par = $(this).parent('form');
if(par.has('.warn').length === 0) {
// do something
alert('nothing');
}
});
});
