  1. POHelp with jQuery validate and a Zip code restriction based on the 1st three digitss
    text
    copied!<p>I am assuming I need a regular expression here? </p> <p>I have a zip code field and the zip codes must be in the city limits of Chicago. Luckily all the zip codes begin with 606. So I need to poll the input to make sure that the zip code entered is 5 digits and begin with the numbers 606:</p> <p>My input is basic enough:</p> <pre><code>&lt;label for="dzip"&gt;&lt;span class="red"&gt;&amp;hearts;&amp;nbsp;&lt;/span&gt;Zip:&lt;/label&gt; &lt;input name="attributes[address_zip]" id="dzip" type="text" size="30" class="required zip-code" /&gt; </code></pre> <p>And then my script for city was easy enough. I just need to apply it to zip-code as well:</p> <pre><code> jQuery.validator.addMethod("Chicago", function(value) { return value == "Chicago"; }, '**Recipient must reside in Chicago City Limits**'); </code></pre> <p>May help if I show how the plug-in functions for phone-numbers (US). Basically I need to translate this to zips:</p> <pre><code> jQuery.validator.addMethod("phoneUS", function(phone_number, element) { phone_number = phone_number.replace(/\s+/g, ""); return this.optional(element) || phone_number.length &gt; 9 &amp;&amp; phone_number.match(/^(1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})-?[2-9]\d{2}-?\d{4}$/); }, "Please specify a valid phone number"); </code></pre> <p>What does this part do/mean?:</p> <pre><code>phone_number.replace(/\s+/g, "") </code></pre> <p>I dropped in the phone part directly from an example on the validate site.</p> <p><strong>Final answer from all the great (and quick) input here was this:</strong></p> <pre><code> jQuery.validator.addMethod("zip-code", function(zip_code, element) { zip_code = zip_code.replace(/\s+/g, ""); return this.optional(element) || zip_code.length == 5 &amp;&amp; zip_code.match(^606[0-9]{2}$); }, "Please specify a City of Chicago Zip Code"); </code></pre>
