[Javascript] Is Numeric Function

[Grinwald, Uri]

It seems that after walking away from my code for a breather, upon
retutning Peter's suggestion seemed to work just fine. I initially
attempted this the first time but had a syntax error.

Thanks to all those that provided me with their advice.
Cheers.
Uri

First, looked it up and the "-" is illegal for variable names in js,
underscore or letter first.

If you add a space to your pattern, is the space significant? So if you
have 333 333, is that 333333 as a value or does the space mean
something? If a space means something then you have "coded" data, not
just numeric, so, that's important to document 'cause it's a pain to
keep track of and causes all kinds of errors down the stream...

	What about just "0123456789.()- ";  ?

	\n is a newline character, as in when you hit the Enter key.
Spaces are string characters just like (almost) everything else.  If a
simple space in the string doesn't work, try escaping it as in "\ ".

Thanks Peter.
What I was trying to say with my first question was the following. This
line in the function -->  var ValidChars = "0123456789.()-"; How can I
add an empty space as valid? I tried \n but that did not work.

Thanks,
Uri

Hi Uri,

	I'm not exactly sure what you're asking in your first question,
but to replace in Javascript, you should be able to use

myString.replace(" ", "-");


Cheers,

Peter

Hi List Members.

I have a function that checks for numbers:
It won't allow for space, so I need to either reflect that an empty
character is allowed within the function.

On a separate use of this function how can I replace any empty spaces
with a "-" Here is my function at the top of page. I call all my
validations further down with a validate(obj) function.


function IsNumeric(passedVal)

{

var ValidChars = "0123456789.()-";
var IsNumber=true;
var Char;
if(passedVal == "")
	{return false;}
	for (i = 0; i < passedVal.length && IsNumber == true; i++)
	{
		Char = passedVal.charAt(i);
		if (ValidChars.indexOf(Char) == -1)
		{
		IsNumber = false;
		}
		}
	return IsNumber;

	}

////and later I do the following...
if(!IsNumeric(obj.dynTelEng_11.value))
	{
	msgError = msgError + '\n' + 'Telephone Number must be numeric';
	}

Etc...

Any help would be  greatly appreciated.
Uri
