Using AJAX to Build a Web Site Indexing Application with Prototype


One of the best ways to take advantage of the numerous features that come packaged with the Prototype JavaScript library is by using it for developing a real world application. So, welcome to the second installment of the series "Building a web site indexing application with Prototype." If youíre interested in utilizing this robust package for creating an extensible system that indexes web site data, this series will offer you a straightforward guide on how to do this, with minor hassles.

Using AJAX to Build a Web Site Indexing Application with Prototype
(Page 1 of 4 )

Introduction

In order to refresh your memory of the topics that I discussed in the preceding article of this series, let me remind you that I started creating a simple front-end to let users submit information about their web sites, including the pertinent URLs, titles, and a few short descriptions about the sites' natures.

In addition, this front-end allowed you to display, on the web page, a list containing data corresponding to all the submitted web sites. In this way it implemented a simple indexing system that could be easily incorporated into either existing or future web applications.

However, although the basic user interface that I developed in the first article of the series might give you a vague idea of how this indexing system is going to work, the truth is that I need to appeal to the help of Prototype to implement a fully functional mechanism that really indexes web site data.

So, taking into account this requirement, over the course of this second tutorial of the series, Iím going to show you how to use the capabilities that come with Prototype to provide the application with the ability to add new web sites to the index, as well as to display the complete listing of sites that have been previously stored.

Having introduced all the topics that I plan to cover in this new tutorial, letís continue building this Prototype-based web site indexing application. Itís going to be instructive indeed!
