How to read an array with javascript from a form

Question

This is the question, I have a form that contains a number (not always the same amount) of inputs. All that inputs are tagged by the name ("qtyv[]") and all have the same id ("qtyv").

I want to sum all the values of that inputs, but I dont know how to get that data with javascript.

Any ideas?

Qty 1= <input type="text" id="qtyv" name="qtyv[]" />
Qty 2= <input type="text" id="qtyv" name="qtyv[]" />

...

I want to sum the values of all that inputs...

Can you provide an example of your code/form that you are trying to tally? — camelCase, Nov 26 '14 at 18:32

Solution: A loop...

var i = 0;
var qty = 0;
while (document.getElementsByName('qtyv[]')[i]){
qty += document.getElementsByName('qtyv[]')[i].value;
i++;
}

When i reach to the limit of inputs, that function will return undefined so the while will exit.
