If you’re going to do any amount of coding for cloud applications then I highly recommend that you learn a little bit about JQuery.

For the uninitiated, JQuery is a cross-browser Javascript library. You first need to have a pretty good understanding of Javascript if you want to use JQuery, but once you get the hang of it then you’ll see how powerful it really is.

If you want to learn how to use JQuery in Open Visual Studio 2010 then I highly recommend a JQuery tutorial. You’ll first be directed to set up a ASP.NET website. You might as well do that anyway because JQuery works pretty well with the .NET programming language and with ASP.

Next, you’ll be directed to download the JQuery plugin and put it in the root folder of your website.

If you’ve ever looked at the code of a website and noticed a dollar sign symbol – like this: $ – then you’ve seen JQuery. Now, you just have to learn what it does and how to control it to do what you want it to do.

Let’s look at a couple of sample selectors:

  • $(“#container”) returns an array containing element which has id = container
  • $(“span”) returns an array containing all span elements.

Those are pretty simple selectors. You can take a complete JQuery tutorial at AJAXTutorials.com.
