Question

jQuery map is returning : data:["1", "8", "5", ".", "9", "0"] when the input val is 185.90 – why the value is being splited?

The code:

var $cel = $.map(
  $('td:nth-child(' + (i + 2) + ') input').each(function() {
      $(this).val();
  }).val(), function(value) {
      return value;
 );

 return {

        data: $cel
  };

Answer 1

.val() returns the value of the first matched element. And that value is a string,or in other words array of chars.That is why, you are iterating through the chars of the value‘s string.

Probably, you want this:

var $cel = $.map( $('td:nth-child('+(i+2)+') input').get(), function(elem) {
  return +elem.value;   //'+' will convert string to number
});
