This will help to have alphanumeric string, leaving out special characters. function  validateAddress(){        var  TCode = document.getElementById( 'address' ).value;           if ( /[^a-zA-Z0-9\-\/]/.test( TCode ) ) {           alert( 'Input is not alphanumeric' );            return   false ;       }           return   true ;        }
