Script to check if the user selected item from downdown list or not

I have a script that runs when the form user leaves a drop-down list object after you make a selection. I don't want the script runs if the drop-down list object is empty (the user does not have a selection). I need to create an if statement to test if the user makes a selection in the drop-down list. All the items in the drop-down list are 4 digits.  I prefer the stated case is in the Exit event. The following script is correct?

If (dropdown1.isNull | dropdown1.rawValue.length! = 4) {}

xfa.host.messageBox ("you must make a selection, the drop-down list name");

}

else {}

set the script to execute here

}

It seems that your script is generally good, but you try to do something more in the message box? Did you mean to carry the name of the drop-down list in the title or as part of the message?

If you are not allowing the custom entry, you only need the null control. Of course, we only talk about one millisecond, or to check the length of your string. So, you are not asking all devices to perform intense processing.

If I were asked to do, this is what my script would look like.

If you allow custom entries, you must specify what the problem is for the user.

  • Count the items in the drop-down list by repeating the subform if the user selects "S/o".

    I'm counting the number of drop-down lists the user selected "N/A" in a repeating subform. I want the total appear in a numericfield or textfield. Here is my script that unfortunitly does not work and my page layout form. I placed it in the ready event: layout so the total is updating the number of changes of N/A.

    Hello

    I put the code in the text box, something like calculate event;

    var result = 0;

    instanceCount var = _Subform2.count;

    var instance = Form1.resolveNodes ("Subform2 [*]");

    for (var i = 0; i)< instancecount;="">

    {

    If (instances.item (i). Table1.row2.score.RawValue == 'N/a') {}

    result ++;

    }

    }

    this.rawValue = result;

    The reference to the "_Subform2.count" will ensure that the code is executed whenever an instance is added or deleted.

  • Check if the user has selected box element apex before the loading of the page

    4.2.1

    THM:2

    Hello world

    I have two classic reports with different conditions but even select the columns based on a sql that uses the apex_item.checkbox2 element that allows users to select the lines and run some process. I also have a radio unit that hides and shows these two reports. However, it is possible that the user select a few lines and without doing anything click on the radio button that will present the page and all the lines that earlier he had chosen will be lost. I want that we should be able to pop an alert if there are checkboxes checked and the user tried to hit the button of the radio looks like the APEX_APPLICATION. G_F01. Count is not available at the time the page is submitted. We thought to use a pl/sql to see if APEX_APPLICATION DA. G_F01. Count > 0 then trigger an alert to confirm.

    Any ideas on how to do this?

    Thank you

    Hi FAC586 - basically, there are two parts of the report, were grouped products consolidated (as master) and the other report has all the products of the child. So based on the option the user selects that he sees who discovers and processes information.

    I tried to create the DA, but he does not seem to fire and I'm sure it would be because I have something wrong.

    No, in this case, there was a typing error in my JS expression above (this is what happens when there is no example in the trial against...)

    Must be:$('td[headers="COL_ALIAS"] input:checked').length > 0

    I have page submit on the evolution of radio, given that other elements of the actual application, don't do with this feature which is filled on the loading of the page.

    It does not work. If the present radio on the presentation changes group cannot be controlled by the dynamic action to confirm that it has already been committed before the confirmation message is displayed. Presentation must be made by further action of real on the DA. By the way other values is possible by using dynamic actions or region to submit elements of Page properties.

    But here it is necessary, if the user has activated all the lines, then changes the selection of the radio, it should show an alert to confirm. In addition, what happens if we have a very select in the box by a header label already. Can I use the same label to identify the COL_ALIAS?

    Do not understand the question.

    Don't know what I'm doing wrong.

    As I noted above, an important part of your problem is that you asking what amounts to a series of questions XY rather than the big picture given by presenting the necessary resources. You have been really good on the creation of examples on apex.oracle.com, but they are all fragments of the righteous, which makes things difficult when you try their synthesis in something that works as a coherent whole. Various bits and pieces that have been revealed in recent weeks, it seems like this could be treated using dynamic measurements without having to send the page until the final choice has been made.

  • Impossible to delete previously selected items from the drop-down lists at the click of the button Reset on a page of the screen.

    Hello

    I'm unable to clear previously selected items from the drop-down lists at the click of the button Reset on a page of the screen. The code I did to clear the previous value when the click on the button Reset is as below.

    {} public void onReinitialize (ActionEvent actionEvent)

    System.out.println ("onReinitialize is called ::");

    UIComponent uiComp = actionEvent.getComponent ();

    If (uiComp is nothing)

    {

    otherwise we use the button that we linked to that bean

    uiComp = getButtonResetByBean ();

    _logger.info ("reset fields: buttonID =" + uiComp.getId ());

    }

    on the other

    {

    _logger.info ("reset fields: CompID =" + uiComp.getId ());

    }

    Pass the component inside the uniforms, UIXForm, UIXSubform, UIXRegion, UIXPopup, RichCarousel

    or RichPanelCollection that contains the components to reset

    getTextIDLOV () .setValue (null);

    ResetUtils.reset (uiComp);

    }

    Using this code Iam able to clear the entrance to the text box but can not clear previously selected items from the drop-down lists when the reset button is clicked

    Can anyone please help on this issue.

    It's simple, you can set GenerateIsNullClauseForBindVars = "false" in the viewCriteria who created in EmployeeView

    After doing that it will fill the list of employees only after the Department selection

  • I need to make a required field 'A' if the user selects "OFF" in a ON / OFF dropdown

    I need to make it a required field 'A' if the user selects 'OFF' in a drop-down list box ON / OFF.

    Ideally, I would like to make several required fields - A, B, C, D, but I limit myself to one if someone can help me please.

    You must run a JavaScript script for action 'the blur '.

    If (event.value == "OFF") {}

    this.getField("A").required = true;

    this.getField("B").required = true;

    this.getField("C").required = true;

  • ADF Mobile: contact is created on the device that, after the user selects the button AUTHORIZE

    My app allows users to quickly and easily add contacts on their IOS phone.  I need help capturing the "do not ALLOW" button click.

    Background:

    When you add a contact to the users device phoneGap prompts the user "Allow PAP to access Contacts?".  After that this alert is displayed, the user must select "Allow" or "Disallow".  Of course if the user selects "Allow" my code works perfectly.

    However, if the user selects "Do not allow" I'm not able to capture this selection and process accordingly.

    Here's the line of code that treats the newContact for this user to the application.

    Contact newContact = device.createContact (contact);

    where the 'contact' has been resolved with the user data

    You would offer your expert opinion on how to do it please?

    Thank you very much!

  • How can I stop loading if the user selects another mp3 mp3?

    I work with a lot of mp3 files and I want to be able to stop an MP3 of loading from the server if the user selects a different mp3. How can I do this?  Here is my code so far:

    function startNewSound (): void
    {
    var mySound:Sound = new Sound();
    mySound.load (new URLRequest (tempo + ".mp3"));
    mySound.addEventListener (Event.COMPLETE, soundLoaded);

    sndChannel = mySound.play (0, int.) MAX_VALUE);
    myTransform.volume =-volumeNum/100;
    sndChannel.soundTransform = myTransform;
    }
    }

    Any help is greatly appreciated.

    Your code can be something like this:

    var mySound:Sound = new Sound();// listeners should be added BEFORE load is calledmySound.addEventListener(Event.COMPLETE, soundLoaded);var sndChannel:SoundChannel = new SoundChannel();
    
    function startNewSound():void  {     mySound.close();     mySound.load(new URLRequest(tempo + ".mp3"));}
    
    function soundLoaded(evt:Event):void{     sndChannel.stop();  //previous sound is stopped     sndChannel = mySound.play(0, int.MAX_VALUE);     myTransform.volume = volumeNum / 100;     sndChannel.soundTransform = myTransform;}

  • Sent items from MS outlook do not appear in Thunderbird, but it works in the reverse (envoys since Thunderbird appears in Outlook). How to solve this problem?

    Sent items from MS outlook do not appear in Thunderbird, but it works in the reverse (envoys since Thunderbird appears in Outlook). How to solve this problem?

    I guess you have a pre existing account using the POP Protocol, that not only downloads the contents of the Inbox.

    Hotmail, Live, MSN, Outlook dot com now support IMAP which is a synchronized messaging service, changes in one are reflected in the other.

    File menu (alt + F) > New > existing e-mail account and add your account to the Thunderbird again. Make sure you have "account type selected IMAP and your all synchronized will.

    If it's like my account, your IMAP e-mail account will come with a subfolder under the pop called deleted folder that contains all mail I have downloaded in the past years.

    If you right-click your \new IMAP account in the folders pane on the right immediately after you create it and choose to subscribe you can unsubscribe from this folder if you don't see it

    I had the same problem.  Mine was up here an easy solution.   Right-click on the taskbar and display the properties.  Check hide them icons inactive and click Customize.  I had multiple entries in the items being passed, including volume control icon.  Remove the elements in the item passed I have no idea from whence they came.  I ran MicrosoftFixit50015.msi (a Windows package install).  Then re-checked the past again and all elements had disappeared or been corrected.  SEEMS this file or box on the PC has become corrupted.  I changed the control volume on always point display.  Also, I went to control panel and sounds and re-checked the volume icon to Place in the taskbar.   Rebooted the system and has worked for me so far.  Good luck!

  • An event of a ring of Menu when the user selects the element itself

    As the subject says: I have a ring of menu.  I want to trigger an event if the user clicks on a menu item that has the same value as the vehicle currently has.

    I considered dynamically by registering on ' Ring: Mouse Down ", then pulling the value from that - but I can't understand how to tell if they clicked on the inside or outside of the menu box. Also, I can't assume the menu box, it appears is always the same size, because I'm creating programmatically values of the ring.

    Any thoughts?

    That shed light on the issue. Use a drop-down list box. Any selection in a list box drop-down is always a change in value, so you can use the value change event and capture the same selection twice. I tried and it works. Selected 'Test 1' over and over again, and it still triggers change in value.
