JQuery Select Checkboxes

I am using jQuer开发者_运维知识库y.

I have a list of radio buttons which I am getting this way:

var $selectAllRadios = $('input:radio[value=select]');

Now in this list I want to be able to select all the radio buttons which are currently checked and also the number of radio buttons that are currently checked.

How can I achieve this?

Use the :checked selector to grab the selected radio buttons, and the length property to find out how many there are.

var $checkedRadios = $('input:radio[value=select]:checked');
var count = $checkedRadios.length;

This is a duplicated, you should search the site before asking a question:

Radio button selected?

How to know if radio is checked

As for the number of elements you can always use the length property.

Use this to get the length of the radio buttons that are checked.

$('input:radio[value=select]').filter(':checked').length

To get the length of radio butons that are not checked.

$('input:radio[value=select]').filter(':not(:checked)').length
