title: When validating a form via jquery, ensure field contains at least one letter
body: <p>So, I suck terribly at regex and javascript.  As such, when I realized I needed to validate a form field via jquery to ensure that at least one alpha character was used, I decided to ask you fine folks for some help.</p>
  
  <p>I want to allow user to use apostrophes, spaces, dashes, periods, underscores, and alphanumeric chars in this field.  They must, however, use at least one alpha character.</p>
  
  <p>Here is the validator method I created, which does everything but ensure that at least one alpha char is used.</p>
  
  <pre><code> $.validator.addMethod("nameRegex", function(value, element) {
          return this.optional(element) || /[^a-z/g]+/gi.test(value) || !/[^\.\'\:\-_ a-z0-9]+/gi.test(value);
      }, "Name must contain at least one letter.");
  </code></pre>
  
  <p>Any tips/hints/insights/insults?  Thanks everyone!</p>
