The jQuery validation plugin additional methods provides an example for zipcode range validation. This same example appears within numerous posts on the internet as an example of doing zipcode range validation, but I have found no discussion as to how to expand the range beyond the narrow scope used in this example.<br />
<br />
jQuery.validator.addMethod<wbr />(&quot;ziprange<wbr />&quot;, function(value, element) {<br />
&nbsp; &nbsp; return this.optional(element) || /^90[2-5]\d\{2\}-\d{4}$/.t<wbr />est(value)<wbr />;<br />
}, &quot;Your ZIP-code must be in the range 902xx-xxxx to 905-xx-xxxx&quot;);<br />
<br />
How would I rewrite this function, using regex or otherwise, to validate the range of valid US zipcodes (00544 - 99500) while still allowing for 9-digit zips? I mention this final condition because I have tried using the more basic &quot;range&quot; validation [544, 99950] but it fails to accommodate 9-digit zips and invalidates any input of 6 or more digits.

US Zipcode range validation with jQuery validation plugin

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.
