JavaScript - Regular Expression

I have following regular expresstion
var reg=/\d{5}/
reg.test(txtname)
txtname is textbox
when I enter numeric 5 values it returns false.
can any one solve this problem

your regular expression is wrong to validate 5 digit numeric
correct this as folllows

reg="^\d{5}$";    //

5 numeric digits, such as a US ZIP code.

if you want to any numeric than simply use

\d	Matches any decimal digit. Equivalent to [\p{Nd}] for Unicode and [0-9] for non-Unicode, ECMAScript behavior.

use this ragularExpression:

Use this this-

If Not Regex.Match(textBox1.Text, "^\d{5}$").Success Then

   ' zip code was incorrect
   MessageBox.Show("Invalid zip code")

   Return
End If

Use and let me know.

Is this is correct for unicode characters [\p{L}]?
