Javascript error "Reduce of empty array with no initial value"

Question

I got an error like

Reduce of empty array with no initial value

when do following:

var fields = $(".invoiceli");
$(document).delegate(fields, 'change', function() {
  Array.prototype.reduce.call(fields, function(prev, curr)
    //.....
  });
})

Can someone point me in the right direction?

Thanks!

The reduce function expects either a non-empty array or an initial value as parameter.

Try this

Array.prototype.reduce.call(fields, function (prev, curr) ..... }, null);

Array.prototype.reduce expects 3 parameters, you just have 2, so no initial value is given.
