Webdynpro abap onChange event for input

Hello,
I wanted to know if "onChange" event for input field is somehow possible in wd abap or if it is planned for next ehp releases
of ECC6.
(Like in Developer studio 7.11)
thanks.

Hi Thomas,
Opening in on a Very old post, but i kind of need an onChange event functionality in one of my Web App. Basically we are dealing with a input field which is populated using a barcode scanner and the user wishes to be able to pull all the information related to the material number read by the scanner in an Input Field Element and display the related info in other fields "Without having to hit ENTER". Sounds a bit lazy but thts wht they need.
I was wondering if its possible to modify the SuggestValue functionality to implement such an event. Any pointers to documents which explain how the SuggestValue works? I am just looking for code blocks (even if they are AJAX/Javascripts) tht i can somehow modify to make this thing work.
P.S. Also if there is any other functionality already introduced by SAP since the last comment on this thread to help solve this will be helpful too
Thanks,
Parth

An onchange event for a Lightroom SDK popup_menu

In my plugin I have a popup_menu that I would like to implement an onchange event for (as one would be able to do for such a dropdown menu in Javascript). But in carefully looking over the SDK documentation, I see no way to do this. Does anyone have any advice? I'd like to make the UI change in various ways at the instant the item selected in the popup menu is changed.

Yep: addObserver... just be aware that function really does add an observer (meaning if you execute it multiple times, you will have multiple potentially too many observers observing...).
In future, post in SDK forum not Lr forum.

Get a event for a new received rtp stream in a player

Hi!
I'm trying to implement a RTP-player, that receives a AV-stream and play it. The special thing about this player should be, that even if the stream interrupts, the player wait's on the same IP and port for a new stream and open it in the SAME frame (not like jmstudio in new window).
I try to catch the "ReceiveStreamEvent", so i can restart the player, but i don't get eny events for this. I tried to do it with a "RTPManager", but i don't know how.
Does anybody has a example how to get the "ReceiveStreamEvent", so i know, the RTP-stream has been interrupted?
Thanks

How can I trigger an onchange event for hidden or never displayed item

hi -- I have an item that I don't want displayed on my page -- more info than the user wants or needs; call it B. It needs to be
set by an onchange event from a visible item (A); then, the change of B triggers on onchange to set another item (visible) -- C.
When B is visible on the page, it all works. If I make it hidden or conditionally never displayed, it doesn't work. From the looks of
it, B never gets changed.
How can I trigger this onchange event (from B to set C) with B not visible?
Thanks,
Carol

hi Varad -- Probably more info than you want... but here's the whole chain of events.
Hope it answers your question.
C
**** 1
In A's html form element attributes (simplified; I took out the irrelevant call to jsLookupValue that sets another item).
onchange='jsLookupValue($v("P142_SITE_ID"),"site_id","P142_OBJECTTYPE_ID","objecttype_id","hdb_site_syn");'
**** 2
jsLookupValue is the following.
The statement that actually sets the value of B is: $s(dest_item_name, jsonobj.row[0].RETURN_VAL);
function jsLookupValue(source_item_value, source_column_name, dest_item_name, dest_column_name, lookup_table_name){
// Continue only if there are valid values
if (valueOf(source_column_name)&&valueOf(dest_item_name)&&valueOf(dest_column_name)&&valueOf(lookup_table_name)){
//Check to see if the source_item_value is null (either all spaces or empty
//If it is, set the dest item to null, but only if it's not already --
//otherwise we get into a loop.
source_item_value = trim(source_item_value);
dest_item_value = trim($v(dest_item_name));
if (source_item_value.length==0) {
if (dest_item_value.length != 0) {
$s(dest_item_name, null);
}else{
//This is the AJAX call to the Application Process from step 1
ajaxRequest = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=LOOKUP_VALUE',0);
//Here we are adding that x01 parameter we use in the app process with the value of the objecttype_name field
ajaxRequest.addParam('x01', source_item_value);
ajaxRequest.addParam('x02', source_column_name);
ajaxRequest.addParam('x03', dest_item_name);
ajaxRequest.addParam('x04', dest_column_name);
ajaxRequest.addParam('x05', lookup_table_name);
//Now do the actual AJAX call and put the result in ajaxResponse
ajaxResponse = ajaxRequest.get();
//Check if there is a response
if (ajaxResponse) {
//We need to format the JSON return string and put it in a JSON object
// the formatting is done by a function in the external JSON library
// the jsonobj can be used to retrieve the data returned by the App process
var jsonobj= ajaxResponse.parseJSON();
// And finally, we set the DNAME item with the value of the jsonobj.DNAME
// an array was created in the object with the name row, so that is why you have to include row[0] to retrieve the data
if (jsonobj.row[0].RETURN_VAL != $v(dest_item_name)) {
$s(dest_item_name, jsonobj.row[0].RETURN_VAL);
}else{
} //not setting
}else{
alert('No response from app process');
} //no response
} //no source item value
} //no bad nulls
} //function
**** 3
I won't bore you with app process LOOKUP_VALUE. It just builds an sql query that gets the value for B, aliased to RETURN_VAL.

PERNR is not read in GET PERNR event for some period..

We have one ABAP report where we read financial data of our employees. But there is some PERNRs that is not read in the GET PERNR event the program skips to END-OF-SELECTION. I have all authorization to access this kind of data through other txn like PC_PAYRESULT. And this data appears in another ABAP reports. We've noted that the PERNRs that not appears doesn't have the Hiring Actions. And the data is read for this year 2007 but not to 2006 when the Action occurred. Does anyone knows what may be causing this?
Thanks,

When you say custom, you mean, not standard report right?
TABLES: pernr.
INFOTYPES: 0001.
GET pernr.
Verifica seleções
CHECK pernr-werks IN pnpwerks.
CHECK pernr-btrtl IN pnpbtrtl.
CHECK pernr-plans IN pnpplans.
CHECK pernr-kostl IN pnpkostl.

END-OF-SELECTION.
perform xyz.
We use a custom report category with the fields:
PNPXABKR
PNPPABRJ
PNPPERNR
The program checks if PNPPERNR is not initial.
When we executes it with PNPXABKR = 02, PNPPABRJ = 2006. Some PERNR does not are read. The programa skips to 'perform xyz'. We found out that these PERNRs don't have the Action Hiring. We don't know if its because of it.

Getting onButtonDown event for JTextField

I would like to be able to clear the text from a JTextField when the user clicks the field.
JTextField myField = new JTextField("Click Me!",8);
myField.setActionEvent("clicker");
myField.addActionListener( new ActionListener(){
                         public void actionPerformed(ActionEvent e){
                             if(e.getActionCommand().equals("clicker")){
                                  myField.setText("");
                         } } );This only works when the user presses return while focused on the box. Is there an inherited method that allows for mouse-click action listening?
Thanks in advance.
- Tim

I would like to be able to clear the text from a JTextField when the user clicks the field.Are you sure that you want to be doing this? This sounds like an annoying feature for the user.
Example: the field is an address field and the user had typed some long text like "Pensylvannia Ave.". Later, they realize the typo, and when they go to click in the field to correct it, POOF it's all gone. Not very desirable IMO.
You might want to look into a FocusListener, where you can highlight the text on focusGained. This will allow for easier editing, while still maintaing the current value.
Hope this helps.

How to register an event for LV event structure from WinApi "PostMessage"?

Hello experts,
I'm using a standard cardreader (RS232/USB) which I access via the manufacturer's API, this works fine so far. However I don't want to poll the status of the reader all the time. The cardreader sends windows messages using the WIN API "PostMessage" as soon as there is a status change (insert card into reader, reader disconnect etc.)
Now how can I use this fact to get an event for my event structure? Any ideas?
Thank you
Melanie

hello Melanie,
This may be tricky but you could use the Windows Message Queue Library example to get the messages from the USB drivers;
http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3E7AC56A4E034080020E74861&p_node=DZ52071&p_submitted=N&p_rank=&p_answer=&p_source=External
And from then create a custom user event based on the POSTMESSAGES received;

Custom UIView not receiving touch events for fast mouse clicks in simulator

I'm having a problem in the simulator where if I click fast in a UIView inside a table cell that is setup to receive touch events, it doesn't receive them. But if I click slow (holding down the button for a little bit) the view gets the touch events. I can't test it on the device. Is this a known problem in the simulator?
Thanks.

Hi George,

OnChange in htmlb:inputField

Hi,
I have 2 input fields with type DATE. When I change a second one I need to re-load a page again to :
1] Check a second value is greater than first value
2] Fill tabView with a some values.
I haven't found a on-change event for inputField.
Any proposed solutions ?
Thank you.
Marian

Hi,
thanks for your replies.
All of your answers are very helpfull and I learned from them a lot.
But unfortunatelly my problem is this : I have inputField with type "DATE" and showHelp="True" in my form.
When I enter a date manually I submit a form for a next processing by JavaScript. Thats OK. But when I choose a date from "dateNavigator" a value is changed but no event generated.
So I tried to hang up an event handler to next field in my form : "dropdownListBox-onClientSelect". A javascript function assigned to this event is not run and when I define onSelect event handled then "server side event" is triggered, but not client side Javascript.
My questions are:
1) is here any possibility how to react to date selection for inputField in dateNavigator help (javascript or server side)
2) what can be a reason of a not triggered javascript function for dropdownListBox defined as onClientSelect parameter ?
Thank you for your answer.
I would like to mark your answers as a "very helpfull" but this radiobutton is dissabled so I can mark it as helpfull answer.
Thanks again.
Marian

Onchange events when transforming select lists for EXTJS integration

Hi,
We have the folloiwng code that transforms select lists to extjs combo boxes
var selectfield = Ext.query('select[class!="shuttle"][class!="multiselect"]');
for (var r = 0; r < selectfield.length; r++) {
    //If there is an onchange event then don't convert as onchange is lost
    //This is used for cascading LOVs so we need to find a way of getting this to work
    if((selectfield[r].onchange == '' || selectfield[r].onchange == null) && ((r>0 && selectfield[r-1].onchange == null) || r==0) && selectfield[r].id != 'apexir_NUM_ROWS') {
      var newselect = new Ext.form.ComboBox({
        //hiddenId: selectfield[r].id,
        //hiddenName: selectfield[r].id,
        id: selectfield[r].id,
        typeAhead: true,
        triggerAction: 'all',
        transform: selectfield[r].id,
        width: selectfield[r].clientWidth+5,
        emptyText:'Please select...',
        forceSelection: true,
        maxHeight: 200,
        disabled: selectfield[r].disabled
}The code does not convert select boxes that have onchange events as the code above seems to suggest they get lost when transforming. Does anyone know if that is the case, and if not how I amend the code to include the onchange events from the original select lists.
Regards
Paul

Hi Vee,
Thanks for pointing it out -- here at work the only version of IE I have is 6 and I assumed (as usually is the case) it was because of a bug in that specific version. However, I have the all-powerful, (allegedly) standards-compliant IE 9 at home and it behaved exactly the same way!
So you cannot say this is due to an old, non-supported browser. Surely it fits in the bug category then? After all events should not be triggered at random...
Thanks also for the suggestion to fix it. I didn't try it because, in the end, I found out that if I use onchange instead of onblur (in the text field) the problem doesn't occur! onblur would be better, but onchange works fine for what I need.
Thanks
Luis

Unable to get automatic event handling for OK button.

Hello,
I have created a form using creatobject. This form contains an edit control and Search, Cancel buttons. I have set the Search buttons UID to "1" so it can handle the Enter key hit event. Instead its caption changes to Update when i start typing in the edit control and it does not respond to the Enter key hit. Cancel happens when Esc is hit.
My code looks like this -
Dim oCreationParams As SAPbouiCOM.FormCreationParams
        oCreationParams = SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)
        oCreationParams.UniqueID = "MySearchForm"
        oCreationParams.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable
                Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.AddEx(oCreationParams)
oForm.Visible = True
'// set the form properties
        oForm.Title = "Search Form"
        oForm.Left = 300
        oForm.ClientWidth = 500
        oForm.Top = 100
        oForm.ClientHeight = 240
        '// Adding Items to the form
        '// and setting their properties
        '// Adding an Ok button
        '// We get automatic event handling for
        '// the Ok and Cancel Buttons by setting
        '// their UIDs to 1 and 2 respectively
        oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Search"
        '// Adding a Cancel button
        oItem = oForm.Items.Add("2", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 75
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Cancel"
oItem = oForm.Items.Add("NUM", SAPbouiCOM.BoFormItemTypes.it_EDIT)
        oItem.Left = 105
        oItem.Width = 140
        oItem.Top = 20
        oItem.Height = 16
        Dim oEditText As SAPbouiCOM.EditText = oItem.Specific
What changes do i have to make to get the enter key to work?
Thanks for your help.
Regards,
Sheetal

Hello Felipe,
Thanks for pointing me to the correct direction.
So on refering to the documentation i tried out a few things. But I am still missing something here.
I made the following changes to my code -
oForm.AutoManaged = True
oForm.SupportedModes = 1 ' afm_Ok
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.SetAutoManagedAttribute(SAPbouiCOM.BoAutoManagedAttr.ama_Visible, 1, SAPbouiCOM.BoModeVisualBehavior.mvb_Default)
        oButton = oItem.Specific
        oButton.Caption = "OK"
AND
oForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.AffectsFormMode = False
I get the same behaviour OK button changes to update and enter key does not work.
Could you please tell me find what is it that i am doing wrong?
Regards,
Sheetal
