JavaScript and Ajax

Summary

This chapter is pretty advanced. It has been all about increasing the performance and usability of your web pages.

You found out that that you can use JavaScript with the ASP server controls to bypass unnecessary postbacks to the web server. This allows you to add some DHTML to your page to make it stand out and be more responsive to the user.

The last thing I covered in this chapter was Ajax. Ajax is a technique that allows you to make asynchronous calls to the web server and get back results with no postback involved. While this involves a lot of JavaScript, the trade-off is often blazing speed in updating your web pages. If there is no rendering of the page when fields are updated, then there is no flicker, and the page will be more like a desktop application for the user.

The next chapter deals with what to look at if you want to take your web programming to the next level. Hopefully, this book will only be the starting point for your new website programming skills.
