$('input:checked').length will do if you do not have any other input tags than in this form.

find how many are checked,

$(boxes).size();

or

$(boxes).length();

you also do by this

you have to define class for checkBox and then follow below

var chkLength = $('input.className:checked').length; alert(chkLength);

this will print your total no of checkboxes from list

Doing it with jQuery would shorten the code and make it more readable, maintainable and easier to understand. Use attribute selector with :checked selector
