validation code

[spicymango]

I need to put a validation code that allow only Letter, Numbers abd spaces. I have the following code that allows only Letter and numbers. but not spaces, how can I make it so it allow spaces as well?

Thanks

<script type="text/javascript">
function alphanumeric(alphane)
{
	var numaric = alphane;
	for(var j=0; j<numaric.length; j++)
		{
		  var alphaa = numaric.charAt(j);
		  var hh = alphaa.charCodeAt(0);
		  if((hh > 47 && hh<58) || (hh > 64 && hh<91) || (hh > 96 && hh<123))
		  {
		  }
		else	{
                         alert("Your Alpha Numeric Test Failed");
			 return false;
		  }
 		}
 alert("Your Alpha Numeric Test Passed");
 return true;
}
</script>

A quick look at

http://www.asciitable.com/

shows me that the ASCII code for a space is decimal 32, so just add that to your list of acceptable alternatives.

Regular Expressions may be another option for you, your validation needs are simple enough it would seem in this case for the regex not to be too complex.

[tt]function alphanumeric(alphane)
{
return [highlight]![/highlight]/[^[highlight] [/highlight]0-9A-Za-z]/.test(alphane);
}[/tt]

One question in you regex, How does it know to include space also as true?
