Sum using jQuery each function without global variable

Question

I want to add some HTML elements that have the same class name.

So, the code will be like this with jQuery.

$(\".force\").each(function (){
    a +=          


        

Answer 1

Don't want a global?

(function() {
    var a = 0;
    $('.force').each(function (){
        a += parseInt($(this).text());
    });
    $('#total_forces').text(a);
})();
