Problem with small jquery script

I have a class of text boxes that triggers the change event for that class.  I need to find out which control actually triggered the change, and be able to check for NaN before running calculations.  This is what I have but $(this) comes back ""

$('.cal').change(function () {
                 var test = $(this).text;
                 var test2 = $(this).val();
                 if (isNaN($(this).val())){
                     $this.val(0.00);
                 }
                 Calculate();
             })

Hi,

could you please try this:
$('.cal').change(function () {
                 var test = $(this).text;
                 var test2 = $(this).val();
                 if (isNaN($(this).val())){
                     $(this).val("0.00");
                 }
                 Calculate();
             })

You had a typo $this vs. $(this) as well as you set the value of an input you should use strings hence setting $(this).val("0.00"); instead of $(this).val(0.00);

var test2 is getting a value now of ''

so why doesnt isNAN($(this).val() come back as false.  Outside of that I think we got it.

thank you

Ok, so the picture shows the value, I need to capture if its not a number, or "" 

thank you

Hi,
you are right - isNaN("") or isNaN(" ") return false.
Update:
$('.cal').change(function () {
                 var test = $(this).text();
                 var test2 = $(this).val();
                 if (isNaN($(this).val()) || $(this).val() == ""){
                     $(this).val("0.00");
                 }
                 Calculate();
             })
