We're using the date input component as part of some parameterization on a page. So, as soon as the onChange event fires we want to go fetch some more data.
The problem is that the onChange fires too often as a user is typing. If I type just "Nov" that's setting a valid date of Nov-01-YYYY, and so the onChange event fires. I believe I would like to fire the onChange only when a full date has been entered, or the enter key is pressed, though I'm open to other ideas.
DateInput does not currently provide such a feature. Sounds like you're requesting an onConfirm handler. GitHub is the place to request features.
I want to create a dynamic action, that will set a value to an item on the page, when the value of another item (autocomplete text field) is set.
So the proccess goes like this:
Click on the autocomplete field
type some letters
choose one of the suggested values
I cannot find an event that will be executed when the selection of one of the suggested values happens. This way, I cannot see how I can read the value of the autocomplete field, once a suggested value is selected.
The change event doesn't fit my needs, it doesn't execute when one suggested value is selected.
I had the same problem, found this link: https://community.oracle.com/thread/2130716?tstart=0 and modified my dynamic action as follows to get the desired behaviour:
Event = Custom
Custom Event = result
From the link:
the problem seems to be the default behavior of the browser. When you
enter some text into the autocomplete and the list is displayed, the
focus is still in the text field. Also if you use the keyboard cursors
to pick an entry the focus will still be in the textfield. That's why
the change event of the textfield doesn't fire. It only fires if you
leave the field.
On the other side if you pick an entry with the mouse, the browser
will remove the focus from the text field for a moment (before the
JavaScript code puts the focus back), because you clicked outside of
the field. But that's enough so that the browser fires the change
event.
I had a look into documentation of the underlaying jQuery Autocomplete
widget
(http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/) and
there is actually an event called "result" which can be captures if an
entry is selected from the drop down list.
Try "Lose Focus" as event. It will trigger your dynamic action when you leave the autocomplete field, i.e. your curosr is moved to another field.
This probably depends on the APEX version you are using.
In case of 18.2, because the underlying component is based on Oracle JET's "inputSearch" component, you need to use following configure to capture the select change event for text with autocomplete:
event: Custom
custom event: ojupdate
Reference:
https://docs.oracle.com/cd/E87657_01/jet/reference-jet/oj.ojInputSearch.html#event:optionChange
I turned on the browser console, then turned ApEx Developer toolbar debug, and found that, on the contrary, the "Change" event does fire upon user clicking with the mouse on one of the selections. However if the user uses keyboard (type a few letters to narrow the list down, then use down arrow key to arrive at desired value, then press enter) then the Change event does not fire, just as you say.
Moreover: even when you do get the value sent back via mouse-click initiated Change event, the value isn't the autocomplete's complete and valid value, but instead the possibly partial and wrong-case value just as typed by the user. I.e., the the change event's submission of the value precedes the autocomplete's substitution.
The answer that #VincentDeelen gave is the best alternative that I can see, although it doesn't quite give that "instantantenous synchronicity" feel. You could maybe use the "Key Down" event, but be careful with that. You could get a really excessive amount of web and db traffic as each and every keystroke (including corrections) results in another firing of the dynamic action.
Testing environment: ApEx 4.2.3 with Chrome 33 as well as IE 9.
p.s. This might be worth a mention to the ApEx development team as well.
It's not really ideal, but you could use onfocus(). I'm looking for the same thing you are, I think, a custom event that fires when the selection of a suggested value happens. I haven't found it yet though and that is my work-around for now. It will run whatever function you've created for this initially with no value, but once the selection is made it will return focus and run the function again with the right value. Like I said, not ideal but it works.
Jeffrey Kemp is right. You can set it up through a dynamic action using the custom event, result. You can also register it on page load using document.getElementById("{id}").addEventListener("result", {function}); or $("#{id}").result( function( event, data, formatted ) { //something here });.
Oracle apex 19 now added a "component event" when you create a dynamic action called "Update [Text Field with autocomplete]" - this action is fired when you select a value from the list, but not when you leave the field (similar to adding the custom event "ojupdate").
I have a form which is using DateTimePicker on one of the inputs. I would like the user to be able to select the date/time by using the buttons which KendoUI attaches to the right of the input field, however I don't want the user to free-type into the text field (to save me having to verify formatting or rubbish input).
It is possible to add readonly attribute to the input, either in HTML or by calling .readonly() method on the DateTimePicker object. This makes the text field un-editable, however it also prevents the click events on the date/time selectors from firing.
So, how do I prevent the user from being able to edit the textbox field manually?
Thanks in advance.
Yes, you can set the readonly attribute only of the input from which the datepicker was created:
<input id="datepicker">
<script>
$("#datepicker").kendoDatePicker().attr("readonly", true);
</script>
Here is a live demo: http://jsbin.com/uwayit/1/edit
I'm facing a problem that I can't understand. I'm using Kendo Grid with InCell edit and I have a DateTime field in my Model.
When the grid enters in edit mode, the calendar is shown, but the grid only saves the inputed value if I select the value from the calendar. If I input the field manually, the value is not saved and the cell is not marked has dirty.
If it helps, I'm using MVC with Razor sintax.
Tks in advance!
I've found a workaround in Kendo's forums:
By design, the DatePicker does not raise the change event when the value is set programmatically - it raises only if the date is modified by the end-user. In case you need to trigger the change event, you can use jQuery trigger().
For example:
var datePicker = $("#datepicker").data("kendoDatePicker");
datePicker.value("01/01/2001");
datePicker.trigger("change");
Reference:
http://www.kendoui.com/forums/ui/date-time-pickers/datepicker-change-event.aspx
So basically what I did was to force the change event manually.
I have been following this example, http://www.ok-soft-gmbh.com/jqGrid/DependendSelects2.htm, as it is just what I need. I have got it working but it doesnt work when scrolling through records. If you bring up the form and scroll from a UK record to a US record, the list doesnt change. The onChange event only fires when the user selects from the select drop down.
Is there a way around this?
Thanks for your help.

My old demo uses 'change' event handler defined in the dataEvents property of the editoptions. In the dataEvents array one can define other event handlers.
You need just bind keyup to the column exactly like it's described in the answer. In the body of the event handler you can do the same actions as in the body of the 'change' event handler (you can place the code in a function and call it from the both handlers). In the way you should be able to solve the problem.
UPDATED: I updated the old answer and another one which was origin for the demo which you used. The new demo support the navigation buttons (the buttons to edit the 'next' or the 'previous' row) in the editing form.
