Web Development Tips for PL/SQL Programmers

How Does a PL/SQL Programmer Get Started with Web Development?

Learn FireFox’s Firebug or Chrome’s developer tool, HTML, CSS, DOM, AJAX, and JavaScript

Are you an expert server side software developer who needs to migrate to a browser based environment like Oracle Application Express (APEX)? Then this free tutorial is for you; it will help you to “break the back” on the somewhat steep learning curve that is required when you start learning how to effectively use client side browser tools like FireFox’s Firebug and Chrome’s developer tool. APEX expert and author Patrick Cimolini leads you, step by step, from a simple “hello world” web page to some real-world APEX pages; showing you along the way how to use the browser tools to inspect, test, and debug your HTML, CSS, DOM, AJAX, and JavaScript code.

The tutorial introduces the audience to the important browser development tools that are required in order to take advantage of the web’s browser based environment. Students are shown how to analyse and debug a web page by using the development tools that are built into the FireFox and Chrome browsers. The webinar starts with a simple “hello world” web page and then progresses, step by step, into real-world APEX pages where HTML, CSS, DOM, AJAX, and Javascript must be inspected, tested, and debugged. We’ll de-mystify the web tools and help you achieve a level of comfort and confidence when working with the client side web tools.

CSS in APEX

 

>> Patrick:  When you do you bring your Cascading Style Sheet code in or your JavaScript code in to APEX, you always wonder, “Where do I put it?” You got lots and lots of options. The place that you put it in depends on the scope.

 

For example, if you wanted that GoDaddy button to be available to all of the applications in your workspace, you probably want to put that Cascading Style Sheet rather than in the template but into a CSS file somewhere on your web server or perhaps in your workspace images if you can store that inside the database itself rather than on web server. You’ve got choices there.

 

If you wanted the button only in a single application, you could do exactly what I just did – put it into a template. Or you could put it in the header region on your Global page or your page zero. That’s another place you could put it. Or if this was simply a hard code on one page, you could actually put
