How to disable a calendar button....

When you disable a Datepicker field, you can still click the matching image next to that field and doing so will popup the calendar window.

You can easily get this functionality using jQuery:

$(function(){
$('td.datepicker input:text').each(function(){
var i=this.id;
$('#'+i+'_IMG').click(function()
{return (!document.getElementById(i).disabled);});
});
});

This function adds a click event to the Calendar image that will only return true - and therefore do something - if the date field is enabled. You can see how this works on apex.oracle.com.

Why doesn't APEX handle this by itself? I really don't know. Maybe they'll copy this solution (or similar) in the next version....

Roel,

Setting the field with a read only condition will not only make the field into a display only field but also removes the datepicker icon as well. So the functionality is already in APEX.

This also works for the JQuery datepicker that I have implemented thanks to your input.

HI Roels,
I am working for apex development,
2nd point, Add a click event to each datepicker image.
Could u please explain me more detail like where to add it????
Roel said…
Kavitha,

The function itself adds a click event to the image. You don't have to do anything. Just copy and paste the code in your Page HTML Header (and incorporate jQuery of course).

Hi Roels,
Thanks for the link..
the same code, with little change,
$(function(){
$('td.lov input:text').each(function(){
var i=this.id;
$('#'+i+'_IMG').click(function(){return (!document.getElementById(i).disabled);});
});
});

i use for disabling the popup lov but it was not comming.
Please, am i doing anything wrong ?

Kavitha,

Check in your "each" function if the right items are selected.
So does i have a (correct) value? And does the IMG item (i+'_IMG') actually exists?

Hi Roels,

do you have a solution that works with APEX 4.0 (4.0.2) too?

Hi Wolfgang,

The example runs on apex.oracle.com. And that's running apex 4.0.2. So it is working in the latest version of apex.
But in the latest version you probably would use Dynamic Actions to get the same result (without any coding). See the updated example:
Created a (Standard) Dynamic Action on the radio group; if the value = 'Y' (Disable) then Disable the date otherwise enable.
So that's the way you should do it nowadays!

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid. The use case I'll cover right here is probably more common - and therefore more useful!

Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user.The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even worse) while you…

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …

apex_application.g_f0x array processing in Oracle 12

If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one:
then you disable the "Escape special characters" property and the result is an updatable multirecord form.
That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for processing y…
