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. However, I want the opposite. Something along the lines of

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

so that my if statement runs when none of the radiobuttons are selected. What is the best way to go about this?

Answer 1

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 ) 

Answer 2

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

AFAIK, this should work, tested against the latest stable jQuery (1.2.6).
