    Total Floor Area is showing a NaN

    I have a form which is used to calculate residential Floor Area Ratio (FAR). The form is structured into seven parts as follows:

    Part A: Maximum FAR and Floor Area:

    Part B: Gross Floor Area of the main floors of the main house:

    Part C: Gross Floor Area of the basement or cellar:

    Part D: Gross Floor Area of the attic:

    Part E. Gross Floor Area of all accessory structures except detached garages: (including cabanas, guest houses, caretaker's cottages, pool houses, sheds, barns, or other structures except a detached garage)

    Part F. Gross Floor Area of the garage: (not including basement garages)

    Part G: Total Floor Area:

    The Javascript involved in the calculations is as follows:

    Code:
     
    
    <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">

    I have attached the html file as a .txt file for reference, and I have attached a .txt document including all the values I used for testing.

    Why is it showing NaN values? Any help would be greatly appreciated.

    Thank You.

    Re: Total Floor Area is showing a NaN

    Observations:

    1. I wouldn't recommend accessing the form directly via its name, not all browsers would support this. Use something like: var myForm = document.entireForm; and then use myForm instead.

    2. In place of running a skyscraper of IsValidEntry()'s just change it so it could receive an array as a parameter, or run a loop.

    3. I'd recommend checking the result of each validation instead of running the whole structure even if the very first value fails (make all validation methods return a boolean for ex.).
    Code:
    function checkAllInputFields(){
        var result = false;
        var fields = new Array(entireForm.A1.value,
                               entireForm.A5.value,
                               entireForm.A6.value); //...
        for(i=0; i<fields.length; i++){
            if(!(result = IsValidEntry(fields[i]))){break;}
        }
        return result;
    }
    
    function isValidEntry(entry){
        var result = false;
        if(entry == "N/A to this property" || entry == "" || IsNumeric(entry)){
            result = true;
        }else{
            alert(entry + " is not a number.");
        }
        return result;
    }
    4. Javascript already has its own number validation function:
    Code:
    if(isNaN(myString)){
        //this is not a number
    }else{
        //this is a number
    }
    5. Use semicolon at the end of each expression: sometimes it's really difficult to read/edit even your own code when all lines look the same.

    Re: Total Floor Area is showing a NaN

    Thanks for the help and insight, I really appreciate it. I really like the

    function isValidEntry. So how do you think I should modify this to get it to work correctly. Can I use the isNan function to read the D16 value and if the value is (N/A to this property) then exclude it from calculating G1 and if it is a number to use it in calculating G1.

    What do you think?

    Regards,

    Nick

    It's already changed in my first post.

    A strange question... Yes, just add an if statement to the point where you calculate G1 checking D16 value...

    About isNaN(): I've just mentioned this method because I saw you used IsNumeric() for the same task.
