Question

For the last hour I’ve tried several different solutions but none have solved my problem.

I have various input fields containing a decimal number (price of product) e.g. 98.00.

Looping through a list of items, I need to add the fields together:

  // Calculate sub-total
  $('.selected_list li.order_line:visible').each(function(){
    var item_cost = $(this).find('input.item_cost').val();
    sub_total = sub_total + item_cost;
  })

How can I add these items and get a result containing two decimals?

Answer 1

Use parseFloat:

 var item_cost = parseFloat($(this).find('input.item_cost').val());
