Re: How to Pass variable name to a function

Show key headers only | View raw

Thank to all that posted for your help.

1) The reason for only posting code snippets was that form does
calculation of someone else's equations which I could not share.

2) This is fully functional and working but used method which were not
generalized. That was the reason for the inquiry

This is what I have now.

function numeric( field, fallback, name ) {
     var num = parseFloat(field);
     if (isNaN(field)) {
         alert(name + " is not numeric");
         return fallback;
     } else
         return num;
}

<TR><TD ALIGN="RIGHT">
<b>Valve Diameter in Millimetres </b>
</TD><TD>
<INPUT TYPE="text" NAME="VD" SIZE=7  onChange="AInput =
numeric(this.value, AInput, 'Valve Diameter')">
</TD></TR>

When I have more time I will look into implementing what Stefan
suggested about replacing the "isNaN"

Thanks again,

Stan
