Partial Page Refresh ($a_report) and jQuery 1.3 new methods LIVE/DIE

If you are using "Partial Page Refresh" to navigate through the pages of a report, the new methods live and die should be useful. The "Partial Page Refresh" functionality uses the JavaScript function $a_report to request the report's body and then refresh the report without refreshing the whole page (AJAX). Before, we were able to bind a click event to DOM elements. The click event was not propagating itself to new DOM elements created dynamically after the bind action. For example: if you bind the click event to every rows of your report, you have to bind the click event to new rows generated after calling the function $a_report. Now, we are able to bind a live event to our DOM elements. The click event is now able to propagate itself to new DOM elements created dynamically after the bind action. You can try a working example of jQuery Event Live in APEX . Happy Web 2.0 coding! :)

jQuery 1.3 - new release

Good news everyone! A new release of jQuery saw the day. Find more information about jQuery 1.3 on the official website. The major new features are: * Sizzle: A sizzlin’ hot CSS selector engine. * Live Events: Event delegation with a jQuery twist. * jQuery Event Overhaul: Completely rewired to simplify event handling. * HTML Injection Rewrite: Lightning-fast HTML appending. * Offset Rewrite: Super-quick position calculation. * No More Browser Sniffing: Using feature detection to help jQuery last for many more years to come. For more information, read the jQuery 1.3 release documentation . I'll try to do demos showing the new features in the upcoming days... Happy coding!

Generate a "tag cloud" using DynaCloud (jQuery Plugin)

To make your application look more Web 2.0, it's a good idea to add a Tag Cloud section on some pages. ;) I did a little search for a jQuery plugin that can do the job and I found DynaCloud . You can include a Tag Cloud on your page in 4 steps. 1) Add on your page a container for the tag cloud. For good results create an HTML Region and put the following code in the region source. (Set the template to Sidebar Region) <div id="dynacloud" style="font-size:12px;"></div> 2) Load jQuery using Google AJAX Libraries API <script src=""></script> <script> // Load jQuery google.load("jquery", "1.2.6", {uncompressed:false}); </script> 3) Load DynaCloud Plugin <script src="&WORKSPACE_IMAGES.jquery.dynacloud-4.js"></script> 4) Add CSS styles to display the Tag Cloud <style type="text/css"> div#dynacloud { font-size:5px

Google AJAX Feed API

I'll start the year by showing you how to add a simple feed reader to your page. For my demo, I decided to use the feed from the "official" Apex Blog Aggregator . Using Google AJAX Feed API , you can easily load and parse feeds. Using Google Visualization API , you can easily display the information in a datagrid. For more information, consult my online demo of the Google AJAX Feed API in Oracle APEX .
