Jquery to get SelectedText from dropdown
I had the same problem yesterday :-)
$("#SelectedCountryId option:selected").text()
I also read that this is slow, if you want to use it often you should probably use something else.
I don't know why yours is not working, this one is for me, maybe someone else can help...
Without dropdown ID:
$("#SelectedCountryId").change(function () {
$('option:selected', $(this)).text();
}
