Plz urgent!string.match!

[learner]

Hi,

I want to validate whether a string is having only alphabets,
numbers, '-' and '_'.

Is there any way to do this like the one in Perl
( /^[0-9][A-Z][_][-]$/) ?

Let me know the earliest?

[oeyvind toft]

Something like this ?

<script type="text/javascript">
var strSample = 'abd_def-123_-';
var reg = /^(\w|\d|-|_)+$/;
var boolResult = reg.test(strSample);
alert(boolResult);
</script>

Letters and digits are easy, if you only want English language
letters.

That looks like a perfectly good Javascript regular expression, except
that it probably doesn't do what you want.
That regular expression matches only strings on the exact form:
digit letter underscore minus

Try
/^[-0-9A-Z_]+$/g
or the abbreviated form (\d matches digits, \w matches letters or underscore)
/^[-\d\w]$/

^ --- please.

That expression does not do what you want, as has been explained.

Rather than testing whether the whole string contains only those
characters with /^[ characters ]*$/ it may be quicker to see if it
contains any character other than those : /[^ characters ]/ .

The latter process should stop at the first alien; the former, depending
on implementation, probably scans the whole string even if it is faulty.
