I am using DateField as editable one in my application. And I did change event for filter function. Now I want to do the same function for each keystroke. I tried ValueCommit. But it's did nothing. My questions are:
Is there an event one can use when someone changes the actual value in a DateField's TextInput control?
How to use this textinput as a normal TextField component?
Thank you.
You can use keyUp event. It will be rised every time when you release pressed button in the TextField. I think this will make the trick.
<mx:DateField keyUp="datefield1_keyUpHandler(event)" editable="true"/>

I need few suggestions/workarounds. I am having an issue on user experience of ngx-bootstrap inline datepicker.
If the user selected the date range on the same day, some user only click once. The problem is bsValueChange only emit when click twice. So when the user click the apply button on the screenshot, it applies the previous value. What i want to do is if the user did not click twice, i disable the apply button but the v5.3.0 does not have an event emitter for that situation.
Thank you

Hi I would suggest you add some external buttons with some predefined date ranges like in here. quick dates with buttons
Then you can just hook it to a click event and in the method you set the bsValue input to [m().subtract(0, 'days').startOf('day').toDate(), m().endOf('day').toDate()]; where m refers to momentjs.
I have a primefaces autocomplete element which works great except one thig. The problem is that when I enter a valid text (which is mappable to the data behind) but I don't select the element from the propositions, and don't press tab or enter, nothing happens.
So I enter a value and click into another field, the element is not selected and the validation fails. However, I don't want the user to force to explicitly select an item.
My ideas were, that i put an onchange listener to the input element and trigger the primefaces itemSelect event within. But I don't know how to do that, if it's even possible.
Or maybe there are other solutions?
Thanks in advance!
I found a way, although it might not be the most beautiful and easy one.
Maybe it helps somebody...
This is a specific solution for primefaces (5.3), but it should work for other versions too.
$('#form\\:txtAutoComplete_input').val('Foo');
$('#form\\:txtAutoComplete_input').trigger('keydown');
$('#form\\:txtAutoComplete_input').trigger('input');
$('#form\\:txtAutoComplete_panel .ui-autocomplete-item').trigger('click');
For some reason, after the value is entered into the input field, you have to trigger the keydown and the input event in that order. After these events the autocomplete list shows with the matching values. There you have to trigger click on a certain element, so all the backing bean stuff is properly executed.
There is an API for Primefaces widgets.
For instance ;
<p:autoComplete id="gtautoaomplet" value="#{item.soemprop}" completeMethod="#{bean_CrossCheckNew.completeText}" scrollHeight="250"/>
In JS code ;
widget_form_mapingGrid_0_gtautoaomplet.search('foo');
When you write "PrimeFaces.widgets" in your browser console you can see all the widgets available in your page.

Good luck.
I want to call 'onclick' event on listbox. There is 'onchange' event which is called whenever the displayed options changes but I want to call a function when the list box is selected or the displayed option is selected again. Any help is appreciated.
I think by using HTML listbox you cant find Click event. It is Having only change event.Refer This
But You can Do it by some other way Using JavaScript. I found one interesting link Refer This
good Luck.
I am using a editable datagrid and want to autosave the edited information in an editable column. Also, since its a simple text editing I don't want to use itemEditor/Component for the same. I was hoping to have a focusOut event but I dont see any focusOut event for datagrid column(even if its editable?). What event should I be using?
Thanks.
I got it working by using itemRenderer in which I used a text box and handled it with textbox's focusOut property. Still wondering how could I have done it directly from dataGrid's event.
When is one called versus the other? Is there a situation were onChange would be called but onBlur would not be called?
The onBlur event is fired when you have moved away from an object without necessarily having changed its value.
The onChange event is only called when you have changed the value of the field and it loses focus.
You might want to take a look at quirksmode's intro to events. This is a great place to get info on what's going on in your browser when you interact with it. His book is good too.
onblur fires when a field loses focus, while onchange fires when that field's value changes. These events will not always occur in the same order, however.
In Firefox, tabbing out of a changed field will fire onchange then onblur, and it will normally do the same in IE. However, if you press the enter key instead of tab, in Firefox it will fire onblur then onchange, while IE will usually fire in the original order. However, I've seen cases where IE will also fire blur first, so be careful. You can't assume that either the onblur or the onchange will happen before the other one.
An example to make things concrete. If you have a selection thus:
<select onchange="" onblur="">
<option>....
</select>
the onblur() is called when you navigate away. The onchange() is called when you select a different option from the selection - i.e. you change what it's currently selected as.
In Firefox the onchange fires only when you tab or else click outside the input field. The same is true of Onblur. The difference is that onblur will fire whether you changed anything in the field or not. It is possible that ENTER will fire one or both of these, but you wouldn't know that if you disable the ENTER in your forms to prevent unexpected submits.
I think it's important to note here that onBlur() fires regardless.
This is a helpful thread but the only thing it doesn't clarify is that onBlur() will fire every single time.
onChange() will only fire when the value is changed.
onChange is when something within a field changes eg, you write something in a text input.
onBlur is when you take focus away from a field eg, you were writing in a text input and you have clicked off it.
So really they are almost the same thing but for onChange to behave the way onBlur does something in that input needs to change.
onBluris when your focus is no longer on the field in question.
The onblur property returns the onBlur event handler code, if any, that exists on the current element.
onChange is when the value of the field changes.
