Question

I have a table that lists items and has a quantity textbox column that starts with an initial value of 0.

item name | price | quantity
item1     | $1.00 |    0
item2     | $1.00 |    0
item3     | $1.00 |    0

I want to check if all of the rows have 0 as their value.

I’m currently thinking of using this:

var all_zeros = true;
$('input.item-quantity').each(function () {
    //Check for 0 quantity and update all_zeros var
}

Is there a cleaner and hopefully better way of doing this?

Answer 1

The following code will help you:

var zeeroCount = $('input.item-quantity').filter(function(){
  return $(this).val() == "0";
}).length;

var allCount = $('input.item-quantity').length;

if(zeeroCount == allCount)
{
  ........
}

EDIT:

$('input.item-quantity[value="0"]').length;
