Cool JavaScript Ideas

I came across this link this morning, which looks like it holds a wealth of hints for using and optimizing JavaScript.

Some of the things it mentions, such as compressing JavaScript, may make it a bit more difficult to debug your code. Other things, such as putting your JavaScript libraries at the end of the page, are no-brainers and can easily be implemented in APEX with little risk of breaking anything.

Finally, the article mentions using GZIP to compress all HTTP traffic, which will in turn make your site load faster. apex.oracle.com has been using this trick for as long as I can remember. It only takes a few minutes to configure and will increase the performance of almost any site - static or dynamic.

Hi Scott, this is Kalid from BetterExplained -- thanks for the writeup! I'm glad you found the article useful; it seems that even as our home bandwidth increases, webmasters want to put more features in. It's a constant battle :)

Custom Export to CSV

It's been a while since I've updated my blog. I've been quite busy lately, and just have not had the time that I used to. We're expecting our 1st child in just a few short weeks now, so most of my free time has been spent learning Lamaze breathing, making the weekly run to Babies R Us, and relocating my office from the larger room upstairs to the smaller one downstairs - which I do happen to like MUCH more than I had anticipated. I have everything I need within a short walk - a bathroom, beer fridge, and 52" HD TV. I only need to go upstairs to eat and sleep now, but alas, this will all change soon... Recently, I was asked if you could change the way Export to CSV in ApEx works. The short answer is, of course, no. But it's not too difficult to "roll your own" CSV export procedure. Why would you want to do this? Well, the customer's requirement was to manipulate some data when the Export link was clicked, and then export it to CSV in a forma...

Manipulating Images with the... Database?

A recent thread on the OTN HTML DB Forum asked about how to determine the width & height of an image stored as a BLOB in an Oracle table. I mentioned in that thread that I have some code to manipulate an image stored in a BLOB column. This is particularly useful if you’re going to let users upload images, and you want to re-size them to display as a thumbnail. Thanks to Oracle interMedia , it is trivial to manipulate the width, height, and other attributes of images stored in an Oracle table. I’ve created a sample application here which demonstrates Oracle interMedia and HTML DB in action. Feel free to have a look. You can download this application from HTML DB Studio as well. Basically, this application allows you to upload images and perform an operation on the image as it is inserted into the PHOTO_CATALOG table. There are two places where some PL/SQL code is required: an After Submit process on page 2, and a procedure to display the images. Here is the PL/SQL for the After...

Page 0 Branches

What? There's no way to put a Branch on Page 0 of an ApEx application! Or is there... Technically, no - page 0 does not support branches. But how many times do you wish it did? This scenario recently came up: I wanted to put a "Search" box on every page in my application, so no matter where a user is, they can search the site. Currently, it has 10 or so pages, but this will grow to closer to 50 by production. So, thought #1 was to put an text item on Page 0, call it search, and then ensure that each and every page had some sort of Branch to run the search. Not so fun, as this was a tedious task, even for just 10 pages. And each time a new page was added to the application - by myself or anyone else - the search branch would have to be added to the page. Clearly not a scalable solution. With a little bit of help from Raj from the ApEx team, I came up with this solution: Create Page 0, if you haven't already On page 0, create an item of type "Text Field (...
