javascript - Count the number of checkboxes selected without reloading the page?

I'm expanding further on this question.

I currently have an asp.net hyperlink for Select All (NumberOfCheckBoxes) which works, but what I'm looking to do is add another link, possibly just a standard HTML hyperlink for Uncheck Selected (NumberOfCheckedBoxes) and update the value of NumberOfCheckedBoxes as checkboxes are ticked, without reloading the page.

I have javascript already for unchecking them, but not counting them and printing it to screen.

I'm not sure if JQuery is the way to go with this or just standard Javascript.

Thanks in advance for any help.

With jQuery you can:

$("input:checkbox:checked").length;
