PO Box Regular Expression Validation

Question

Here\'s my code, but I can\'t ever trigger the alert.

$(document).ready( function (){
    $(\"[id*=\'txtAddress1S\']\").blur(function() {
        var pattern         


        

Answer 1

This one is working pretty well for us. (php preg_match)

$pattern = '!p(ost)?\.?\s*o(ffice)?\.?(box|\s|$)!i';
