regular expression for alphanumeric value

(0) ShareShare
ReportReport
Posted on by gawasdilip 2,385

I need to validate an attribute value for alphanumeric i.e. VF12345, 12345VF, vc1234, 345cf, fdf455ff,

I have used ^(\d+[A-Z]|[A-Z]+\d)[A-Z\d]*$ this expression but it accepts only uppercase letters. I need an expression that can accept upper or lower both along with numbers,

Any help will be appreciated.

thanks,

Dilip

    Hi Dilip,

    You may try this (JavaScript).

           cString = 'VF12345';

           var pattern=/[^0-9a-zA-Z]/;

           if(!cString.match(pattern)){

    alert("valid");

           }else{

    alert("invalid");

           }

    Hope that helps

    Thanks
