Sum of values from different divs with the same class

Question

For <div> Elements:

var sum = 0;
$('.totalprice').each(function(){
    sum += parseFloat($(this).text());  // Or this.innerHTML, this.innerText
});

You can see a working example of this here

For <input> Elements (inputs, checkboxes, etc.):

var sum = 0;
$('.totalprice').each(function(){
    sum += parseFloat(this.value);
});

Alternatively, if you are looking for an integer, you can use the parseInt() function.
