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.

The text in ckeditor field is not sent when submitting forms for the first time (only on the second time, third time, etc).
For example, If try to create an article's post and submit the form I'll get a validation error: 'The field body is required'. If try to submit again (for the second time or third time), It will work well.
The real problem is when editing! For example, when editing a form the field 'body', among others fields, is filled out with the data from the database. In other words, there are already text in the ckeditor field.
If I try to submit the form for the first time it will not update the body because the text in the ckeditor is not sent; what is sent is the default value (the old article's body, which was filled out with data from the DB).
Therefore, it won't edit unless I get a validation error in other field (if I get a validation error, I'll have to submit again, and that will work).
How to solve this problem? Is this an known bug in CKEDITOR 4? If I don't solve it the users will feel frustrated if they have to submit the form at least twice to edit or to create an article.
Here is a list of plugins I'm using (may be useful to solve the problem):
a11yhelp, about, api, autocomplete, autocorrect, browser, clipboard, colordialog, copyformatting, crossereference, dialog, div, docprops, find, googlesearch, image, link, liststyle, magicline, mathjax, openlink, pastecode, pastefromword, preview, quicktable, scayt, section, showblocks, sourcedialog, specialchar, table, tableselection, tabletools, tabletoolstoolbar, texttransform, widget, wsc
By the way, I downloaded ckeditor using ckeditor builder in their official website.
I opened this issue in GitHub and a guy figured out the problem. His proposed solution worked wel!! Here is what he said:
Workaround
As the issue is more tricky to fix than it seems, for now I propose a
simple workaround: invoke ajaxRequest not on $( document ).ready,
but rather on editor's loaded event:
CKEDITOR.replace( 'editor', {
on: {
loaded: function() {ajaxRequest();}
}
});
Explanation of the issue
The issue is connected with how DOM listeners are registered for given
element:
The order of event listeners for a particular event type will always
be:
The event listeners registered with addEventListener() before the first time the event handler's value was set to non-null
Then the callback to which it is currently set, if any
Finally, the event listeners registered with addEventListener() after the first time the event handler's value was set to non-null.
In case of CKEditor 4, the value of the form's element is modified by
editor._attachToForm private method, which adds event listener to
form's submit event:
ckeditor-dev/core/editor.js form.on( 'submit', onSubmit );
However this listener is added on loaded event, which is fired
asynchronously when editor is loaded – so after registering
synchronous onsubmit handler with the validation logic. This way
editor's field is updated after validating.
Proposed solutions
Update editor's element on formdata event. This way we would have
total control over data being submitted and we would be sure that
correct data is set before submit event. The problem with this
solution is the fact that browsers' support is non-existent; the event
will appear in Chrome 77, however it is still not known if and when
the support will appear in Firefox or Safari.
Update editor's element on every change in the editor's content thanks
to change event. This solution will also fix cases, where some other
scripts are using value not from the editor, but directly from the
replaced textarea – they would get fresh data more often then only
after submitting the form. However this solution requires #1364, which
connects with a pretty big refactoring.
NOTE: AjaxRequest is the function I was using to submit the form togehter with Jquery.
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.
How do you force a Kendo grid to filter data after every character is typed, as in after every letter, not just when I press enter button?
I noticed that Kendo sends requests after every character typed, but without page size, and this request is used for autocomplete. I want to change that to bind this data not to autocomplete, but to the main grid instead.
I am using built in filters, one for each column.
Sorry for later response, I didn't have much time. Anyway as I mentioned in comment, this functionallity is not supported by Telerik. So you have to create everything by yourself.
In following example I have used filterMenuInit event which is fired after you click on filter icon (and only once!). In that event I have modified filter elements to add custom classes and ids. Then in jQuery I am catching keyUp events and adding items into filter.
Here is small example. I have implemented only equals filter, so you will have to do some modifications. But I hope it can help you in next work.
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 Flexicious DataGrid set up, and I have an ItemRenderer set on a certain column. Now, when I am editing an editable cell, and then stop editing it, the DataGrid fires a FlexDataGrid.EDIT_ITEM_END event (or something like that). When this is fired, I want to do a certain action. That's simple enough. The problem though, is I have a special case:
If a user is editing an editable cell and then clicks away from it (which would cause FlexDataGrid.EDIT_ITEM_END fire), but he happens to click on a button which is within the ItemRenderer set on the column, then in that case I don't want to do the action. I don't know how to make an event work like this though.
Basically I'm looking for an event that is FlexDataGrid.EDIT_ITEM_END_AND_CLICKED_ON_ANYTHING_OTHER_THAN_THAT_BUTTON and I'd like to fire that instead of FlexDataGrid.EDIT_ITEM_END. But alas, I checked the docs and that event doesn't exist =-(.
What can I do? Thanks for the help!
Have you tried ITEM_EDIT_CANCEL? This has a triggerEvent which should have a target property that should tell you what display object the click happened on.
