I have used webshims for html5 form validation in a single page app with multiple pagelets(divs). The forms are not submitted but local javascript is invoked after each conversation and collected data is posted .
Next I iterate over all the fields and reset the values.
Then I take the new user back to the first pagelet having first form for the new conversation. This time even after filling the correct values the border does not turn green.
Note:
However when we select the field and click outside the field without filling it. and then after filling the correct data border turns green.
However when we tried to achieve it programmatically iterating over each field resetting it and using javascript focus method, that did not do the trick.
I am sure I must be missing some thing. would be able to point out what.

I'm not sure, what you want to achieve. I would need to see some code. If you change the value programmatically you can update the validation ui with the event refreshvalidityui on the form field. If you want to reset the ui, you can either trigger a reset event on the form or resetvalidityui on the form field
$('input').val('foo').trigger('refreshvalidityui');
or
$('input').val('foo').trigger('resetvalidityui');
or
$('form').trigger('reset');
Please let me know, if this helps.

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 use <p:focus> in two ways:
1. Move to the input field if that field fails validation, i.e. is required
2. If on a page that has an input field that is visible when the page loads then move to that field. But if the page has a lot of introduction text and the input field is way down the page then don't move to the field as the user has to then scroll up to read the start of the page.
How can I have both cases handled? It seems that if I have <p:focus> I cannot avoid the page scrolling automatically way down the page if the first input field is there but I also want to move to the required field if a value has not been given.
Thanks
First, don't use the attribut for to select the default focused element.
Second, you only have to update your p:focus, and it will automatically select the first field where error occured.
For 1: See the answer above or http://www.primefaces.org/showcase/ui/misc/focus.xhtml
For 2: The only solution I know of that can achieve this is to not use the <p:focus/> and implement your own focus code (not to difficult). Detect the position of the first input and if it is far down, don't 'focus' it.
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").
Using autogenerated form from a single database table. The form uses the class WizBtns included in c:\Program Files\Microsoft Visual FoxPro 9\Wizards. The form has Top, Previous, Next and Bottom buttons.
Although the form only has textboxes to enter data for the fields in the table, I have added a custom Text Box from the toolbox which basically intends to display the sum of some fields. I have bound the ControlSource of the text box to a PUBLIC variable costTotal that is created on the form init.
Now the problem is updating the sum of fields in the text box, or simply updating value of costTotal. Where to add the code for this? Adding the code in the form's Refresh method mixes up the value of costTotal, when I press Next button to update all fields with new values, the custom text box displays the sum of the last record which is mysterious.
I would add a method to the form to do the calculation. Then, call that method from the Valid method of each of the textboxes involved in the calculation.
There is nothing wrong with using the refresh event to recalculate the values, just make sure that you call the refresh each time the record changes
If you are using navigation buttons to move between records then the click event of EACH button is an ideal place to issue the refresh request :-
Assuming the textbox is called txtSum and is located on the same form as the navigation buttons then in each buttons click event add this code
dodefualt()
with thisform
.txtSum.refresh()
endwith
Couple of things:
1) do not use the wizards! Make your own base classes. Trying to figure out what the wizard classes do and how to add functionality will take more time that coding your own base classes. Also, the wizard generated code and classes must be at around 10/20 years old, much has changed since then (a polite way to say they suck).
2) Do not EVER use public variables in FoxPro, except for maybe an app object.
If this is a one shot thing, just add default textboxes and buttons and design the form yourself. You will have total control and you will know what each thing does.
I just finished my first CRM callout, and it's working great, but it doesn't actually seem to take effect until the form that calls it is saved. It's a PreCreate deal that assigns a value to one of the attributes present on the form. Is there any way to get it to assign the new value and display it on the form as soon as you load it, or is this just the way it works?
You'd have to add some JavaScript to the onload event of the form and default any form fields that way. Callouts don't fire until after the save event happens, so they can't be used to default fields in the UI.
