Radio buttons not checked in jQuery

Question

I have this line of code for page load:

if ($(\"input\").is(\':checked\')) {

and it works fine when the radio button input is checked. How

Answer 1

This works too. It seems shortest working notation: !$('#selector:checked')

Answer 2

If my firebug profiler work fine (and i know how to use it well), this:

$('#communitymode').attr('checked')

is faster than

$('#communitymode').is('checked')

You can try on this page :)

And then you can use it like

if($('#communitymode').attr('checked')===true) { 
// do something
}

Answer 3

$('input:radio[checked=false]');

this will also work

input:radio:not(:checked)

or

:radio:not(:checked)

Answer 4

$("input").is(":not(':checked')"))

This is jquery 1.3, mind the ' and " signs!

Answer 5

(!$('#radio').is(':checked'))

This worked for me

Answer 6

if ( ! $("input").is(':checked') )

Doesn't work?

You might also try iterating over the elements like so:

var iz_checked = true;
$('input').each(function(){
   iz_checked = iz_checked && $(this).is(':checked');
});
if ( ! iz_checked )
