IsNan locale aware? 1

[MrPeds]

Hi,

I have another noob javascript question, sorry to be a pain!

I have a simple html table. Each row contains a text box where the user enters some percentages. The percentages must add up to 100%.

I have some validation code to ensure that only numbers are entered in the text boxes. What I would like to know is:

1) If a user in Europe enters a decimal like this 25,2 (for 25.2%) can JavaScripts IsNan able to tell what the locale is and verify that this is a valid number?

2) I have some code that adds up the numbers so that they equal 100%. Can JavaScript take account of the numbers locale and add numbers like 25,2 and 10 ?

Is it easier just to ensure that a user enters numbers such as 25.2 10 etc to make things easier?

Thanks,

MrPeds

I don't know. But, you could do something like this to avoid the problem. Regular expressions are my friend.

<script type="text/javascript">
var regexp = new RegExp('^(\\d{0,3})[,\\.]?(\\d*)%?$');
	var cnumber = "23,15".replace(regexp, '$1.$2%');
	alert(cnumber);
</script>

The regex will clean it for you, assuming it matches the pattern. You could remove the % and then check if its a number and within the acceptable range.
