A Degradable jQuery AJAX Email Form for ASP.NET MVC

Pretty much every web site on the Internet features a form for users to provide feedback via email to site owners. This site is no different. Migrating to ASP.NET MVC requires a slightly different approach to that used by Web Forms development, so this article looks at one way to implement a web site contact form using the MVC framework and jQuery that degrades nicely. AJAX functionality is said to be "degradable" if a way is provided for the process to work, even though users don't have Javascript available to them. More...

I've recently done a series of articles that feature calling databases via AJAX using jQuery. In pretty much all of the articles, I have used Web Services as my data access mechanism. Judging from the comments that some of the articles have attracted, this has caused a little confusion. But Web Services is just one mechanism. Page Methods and simple ASPX files are two more. And finally, as pointed out by a commenter, Benny Halperin, ASHX files are yet another option. In this article, I shall review each of these approaches. More...

IP addresses can reveal a lot about your web visitors. For an ecommerce site, the owner or registrant of the visitor's IP address can be very useful information. You could paste each visitor IP address into one of the many free IP Lookup sites available, but that can be time-consuming and tedious. Or you could build your own lookup. This article shows how this can be done pretty quickly. More...

It was bound to happen - you knock up an article on jQuery draggables one day, and the next, someone like Jim ;-) comes along and asks about persisting the position of the dragged item across Postbacks, or even sessions. I suppose it's my fault - I mentioned using draggables in a previous life in the context of saving the position, so it's only fair I share how that's done. More...

Cascading DropDownLists or dependent dropdowns are the signature dish for AJAX applications. I spent quite a while fiddling to try to get some to work, before stumbling across a life-saving jQuery plugin that makes working with DropDownLists on the client-side a breeze. This article shows how it all works, and makes use of the WebService I introduced in my previous jQuery article. More...

Handling JSON Arrays returned from ASP.NET Web Services with jQuery

There appear to be many articles showing how to use jQuery with ASP.NET Web Services around, but the vast majority of them illustrate the use of PageMethods that return a single value - typically "Hello World!" or the current date and time. Not much use in the real world, where you may more often need to call a service that returns a collection of complex objects. Here are a couple of examples that look at playing with more than just simple values. More...

Upload and Crop Images with jQuery, JCrop and ASP.NET

I got given jQuery In Action for Christmas. By nature, I'm kind of a late adopter, and I'm already regretting this fact. jQuery has been around for some time, and I wished I had looked at it sooner. It's a fantastic library that really simplifies Javascript development, and is already attracting a goodly number of plug-ins. JCrop is one such, and while it hasn't yet reached version 1.0, it is remarkably easy to use as a web based image cropper. Here's how to put jQuery, JCrop and a FileUpload control together to allow users to upload images and crop them. More...
