X-Requested-With, AJAX Requests, and Android WebViews

Wed, 11 Mar 2015 18:20:17 +0000

Today we ran into an interesting problem with certain pages of our website not loading for Android users inside their Facebook Apps. We dug down and ran into several red herrings, but ultimately found the problem.

The Problem

If you Google for “X-Requested-With”, or the $_SERVER variable name in PHP HTTP_X_REQUESTED_WITH you will likely find many posts stating that it is a method for detecting AJAX requests. Most major JavaScript libraries and/or frameworks like jQuery will set the X-Requested-With HTTP header for any AJAX requests. So if you Google X-Requested-With or HTTP_X_REQUESTED_WITH you will see blog posts & StackOverflow answers about detecting AJAX requests.

jQuery UI - Disable Title On Dialog

Thu, 16 Sep 2010 05:56:35 +0000

For some reason, this was turning out to be kind of hard to accomplish, and everyone on the internet wanted to do it with JavaScript hacks. My issue was if the JavaScript hack didn’t execute fast enough, causing the title to flash for just a second, so I’d much rather do it with CSS. Unfortunately, there are no built in ways to hide it in jQuery. However, there is an option you can pass in the .dialog() method: dialogClass. This places a custom class in the main div element, allowing you to do something like this:

My 2009 Technology Recap

Wed, 23 Dec 2009 18:55:31 +0000

Its been two years now that I’ve been a more or less “serious blogger.” I had using the term blogger, since when people hear about blogs, they think of people either detailing their entire lives, or pumping some angel. For me, blogging has just been a way to share information with people I know locally, and those I don’t even know who find my blog via searching. I’ve had a few spurts where I blogged quite frequently, but for the most part it was just here and there.

jQuery Tip: Better Toggle

Tue, 15 Sep 2009 18:28:05 +0000

For many web developers, jQuery is the most awesome JavaScript library out there. For me, it has turned JavaScript from being a nightmare into a power tool. I love JavaScript now, where as before I truely hated it. Takes all the hassel out of most compatibility issues across browsers. I spend less time debuging it and more time writing it. While I’m on my goal to write more blog posts, I’m going to share a few jQuery tricks.

Empowering JavaScript Through jQuery

Sat, 25 Oct 2008 00:31:27 +0000

Once I discovered jQuery, my life as a web developer changed. There are few libraries, tools, etc. that I can honestly say have completely changed the way I code. In all honesty, jQuery makes the difficult aspects of JavaScript and turns them into a strength. I recommend it over any other JavaScript library I know. It is smaller, leaner, straight forwards, and more powerful than anything out there. Large companies like Google, Microsoft, and Dell use it. Microsoft is now including jQuery in Visual Studio, their powerful IDE for making websites. If anything, I have yet to meet a person who has used jQuery and has gone to anything else.

ASP .NET 2.0, GridViews, HyperLinkField, and JavaScript

Tue, 08 Jan 2008 04:34:00 +0000

I’ve found some interesting notes on ASP .NET’s GridView, it’s limitations and work arounds. For work I was looking for a way to execute JavaScript from clicking a link on a GridView Cell. An example would be to having a list of transactions and wanting to click a link to update it’s details. I noticed that many functions of GridView used tags to execute JavaScript. An example would be:

<a href="javascript:myFunction('variable');">Link</a>

Since I had experience with the HyperLinkField before, I thought I would add a HyperLinkField to my GridView and set the DataNavigateUrlFields to the needed fields and the DataNavigateUrlFormatString to use the fields properly. I was hoping to accomplish it by using the following code, which in turn I found out this solution does not work:
