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
