NaN Problem

asked on May 6

In a form I am creating I have the following table:

when I click the Date picker I get this:

here is the JS I am using:

$(document).ready(function () {
  
  $.getScript('http://server/Forms/js/moment.js');
  
  $('.cf-table-block').on('blur', 'input', sumtotal);
  $(document).on('click', '.form-del-field', sumtotal);
  
  function sumtotal() {
    var hour = 0;
    var rate = 0;
    var total = 0;
    var subtotal = 0;   
    $('.cf-table-block tbody tr').each(function () {
      hour = moment($(this).find('.hour input').val(), 'HHmm');
      rate = moment($(this).find('.rate input').val(), 'HHmm');
      subtotal = hour.diff(rate, 'hours', true);
      $(this).find('.total input').val(subtotal.toFixed(2));
      total += subtotal;
    });  
         
  }
  
  function parseNumber(n) { 
      var f = parseFloat(n); //Convert to float number. 
      return isNaN (f) ? 0 :f; //treat invalid input as 0; 
  } 

});

What am I doing wrong; How do I make the NaN not appear?

It doesn't look like you're calling parseNumber() anywhere. The subtotal variable just gets set and then used based on what you're puling for hour and rate.

Pieter,

Thank you for helping.  I should have said I was new to coding.  Can you give me an example of where I would put parseNumber() in the code?

I think the easiest would be to use it in the subtotal calculation like

subtotal = parseNumber(hour.diff(rate, 'hours', true));
