A project request recently came up where we needed to track some users responses to a series of questions, then build an account 'home' page based on those responses. Pretty straight forward you'll agree. The problem here arose from the clients using a bespoke online solution that blocked any kind of server side interaction.

I've played with JavaScript cookies in the past to remember display states in JQuery functions, so I thought they would be a great solution to this. This article deals with how to use JavaScript cookies to emulate a normal form submission.

There is a demo of using the JQuery Cookie plugin to emulate forms here.

This article follows one from a few days ago, where I explained how to use the JQuery .attr() method to get html attributes. In this article I will show you how a small change to the same .attr() method will allow you to set the value of html attributes.

I'll also cover the .text() and .html methods as they allow very similar functionality.

This article is the second in a planned series demonstrating some of the key concepts of the JQuery library, and how to use it, starting at a beginner level and working up.

I was recently asked in conversation if it would be possible to have a list of items, and when a user mouse'd over the headers in the list, an image effect happened, IE a thumbnail image was displayed. I figured this would be an ideal use for JQuery, so this article is how to write an incredibly simple JQuery image change.

There is a full demo of this here: JQuery mouse over demo

This article shows how to use JQuery to show and hide many div's at the same time, revealing the content that the user requests. It also degrades gracefully if you turn off Javascript.

Have you ever tried to display a Questions and Answers type page, where the Question is a clickable link that shows the corresponding Answer (FAQ's)? It is quite tricky to make this interesting, and Accessible to impaired users.

A full demo of multiple show and hide divs is here: link

Im my previous article on how to use the JQuery datatables plug I concentrated mainly on the JQuery script, and how to build the AJAX request to receive a JSON response.

In this article I will demonstrate the full application which will include the front end JQuery, building the back end server response and a few tips that I've picked up since implementing the plugin. I am using an MS SQL table filled with UK location data that I also used for a weather webservice, to fill the table.

A full example of this working can be seen here: Data table server side example
