jQuery calculate sum of values in all text fields

Question

I have an order form with about 30 text fields that contain numerical values. I'd like to calculate the sum of all those values on blur.

I know how to select all text fields but not how to loop through them and add up all their values?

$(document).ready(function(){
   $(".price").blur(function() {
    //loop and add up every value from $(".price").val()
   })
});

Answer 1

​

$('.price').blur(function () {
    var sum = 0;
    $('.price').each(function() {
        sum += Number($(this).val());
    });

    // here, you have your sum
});​​​​​​​​​

Answer 2

$(".price").each(function(){
total_price += parseInt($(this).val());
});

Answer 3

This should fix it:

var total = 0;   
$(".price").each( function(){
          total += $(this).val();
});
