field validation needs to accept decimal values -- how please?

[KathyB]

I need this function to accept decimal values (e.g., 2.5 ok, not just
whole numbers between 1 and 5).

I can't find this answer...

thanks, kat

{
alert("The entry must be between " +min+ " and " +max+ ".");
formField.focus ();
formField.selec t();
return false;

I need this function to accept decimal values (e.g., 2.5 ok, not just
whole numbers between 1 and 5).

I would use a regular expression for this, e.g.:

var figure = '1.1';
var reg = /^\d+(\.\d+)?$/;

alert(reg.test( figure)); // alerts true

With this, your function might look like this:

function ValidateSave(fo rmRef,fieldName ,min,max) {
var formField = formRef.element s[fieldName];
if (!/^\d+(\.\d+)?$/.test(formField )) {
alert('Invalid entry!');
formField.focus ();
formField.selec t();
return false;
}

if (formField.valu e < min || formField.value > max) {
alert("The entry must be between " +min+ " and " +max+ ".");
formField.focus ();
formField.selec t();
return false;
}
}

Made an error in my code, please use the following:

function ValidateSave(fo rmRef,fieldName ,min,max) {
var formField = formRef.element s[fieldName];
if (!/^\d+(\.\d+)?$/.test(formField .value)) {
alert('Invalid entry!');
formField.focus ();
formField.selec t();
return false;
}

if (formField.valu e < min || formField.value > max) {
alert("The entry must be between " +min+ " and " +max+ ".");
formField.focus ();
formField.selec t();
return false;
}
}

JW, thanks so much! That works great. I've seen reg expressions
before...but clearly need to go study them a bit.

Thanks again.

Hi again, JW. For some reason, I'm getting an error on this
function...look s ok to me, but the parser (Xselerator) says I'm missing
a "[" or a "(" -- can't tell which. Doesn't give me the exact line, but
when I remove this function, I don't get the error.

Thanks,

Kathy

function ValidateSave(fo rmRef,fieldName ,min,max)
{
var formField = formRef.element s[fieldName];
if (!/^\d+(\.\d+)?$/.test(formField .value)) {
alert('Invalid entry! Please try again.');
formField.focus ();
formField.selec t();
return false;
}
if formField.value < min || formField.value > max {
alert("The entry must be between " +min+ " and " +max+ ".");
formField.focus ();
formField.selec t();
return false;
}
else
{
varScroll = document.body.s crollTop;
document.cookie ="position="+va rScroll;
return confirm("You are about to enter: " +formField.valu e+ " --
click OK to proceed.");
}

Hi Kathy,

The if statement above is where the problem is, it should read:

if (formField.valu e < min || formField.value > max) {

Thanks again! Guess I was too tired.
