What is the initial value of a drop-down list empty?

I wrote a script to populate the items in a drop-down list but only if there is no existing entry.

The problem I have is to acknowledge that the list is empty. I tried to test the value null (if dropdown.isNull = true) and test the

rawValue = "" and a bunch of other things without good result.

I don't know that it's easy, but apparently not for me.

Thanks for the help!

These commands to test the value selected by the user. As they have not chosen anything and yet they will not have a value.

The command:

DropDownList1.items.nodes.length

This will give you the number of items in the DDlist. It is 1 based. Note that it will count all the elements that have been added to the drop-down list by the user.

    Hello experts,

    I use Adobe Forms in SAP.

    My question is, is there a any restriction for additem keyword in JavaScript?

    I mean, even if I use the keyword additem to add the name and value of a drop-down list, it adds up to 10000 files only.

    Please sugest

    A drop-down list is the bad INTERFACE design where an element can contain more than 100 entries. It is very good in tests, but absolutely unacceptable if the form must be used by a person busy doing their work. The choice of Acrobat forms are limited, but consider a list box. Despite this, there may be limits imposed by the system or the implementation.

    Better would be

    (a) stop filling after awhile the list and add an entry saying several elements not shown, running report or use better filter

    (b) be available for all filtering of course lists

  • How to choose a specific value in a drop-down list using javascript

    Hello

    I'm looking for a way to select a specific value in a drop-down list (the first value) using javascript? How would I do that? Thank you in advance.

    Here's how you can select the first item without having to know what it is:

    Set the value of the drop-down list to the first element cb1

    var f = getField ("cb1");

    var val = f.getItemAt (0, true);

    If (val) f.value = val;

    Change 0 to a different index if desired, or use-1 for the last item in the list. More information for the field getItemAt method is in the Acrobat JavaScript documentation.

  • Have the drop-down list boxes become visible depending on the selection in a previous drop-down list box?

    Hi, im doing a form that only shows some options based on the previous selections.

    So far I have buttons which allow a user to select a specific product, and then by using the drop-down combo boxes select some optional features.

    I then have a simple javascript code that bears the name of a product at a price (i.e. the user selects product 'A', the review sections shows priced at $ 99).

    My problem is with additional customization options that depend on previous choices.

    Is it possible to have some drop-down list boxes become visible depending on the selection in a previous drop-down list box? If yes how could I impliment it?

    Currently my best idea is to have a button that could ask the user if he or she had previously chosen a certain selection and then reveal areas of correct drop-down list accordingly.

    Thank you

    Hello

    With a small change I think that the code works as expected. I changed your mainDD.value to event.value, as on the validate event the mainDD.value property cannot be updated as expected.

    script

    this.getField("Dropdown2").display = display.hidden;

    this.getField("Dropdown3").display = display.hidden;

    this.getField("Dropdown4").display = display.hidden;

    Switch (event.value)

    {

    case "a":

    this.getField("Dropdown2").display = display.visible;

    break;

    case "b":

    this.getField("Dropdown3").display = display.visible;

    break;

    case 'c ':

    this.getField("Dropdown4").display = display.visible;

    break;

    by default:

    break;

    }

    end of script

  • Transparency of the IR on bottom of drop-down list filter in IE7

    Hello

    I have a problem with the transparency of the IR on bottom of drop-down list filter in IE7.

    Please try to access http://apex.oracle.com/pls/apex/f?p=36675:2 using IE7.

    If you click on the header of the IR to remove the filter down, we could see the bottom of the filter drop-down is semi-transparent and mix with the data in the table below. IT IS VERY difficult to read.

    The existing market research indicates it is already fixed in the 4.0.1 however I could reproduce still use IE, version 7.0.5730.11

  • Help select the value from a drop-down list box

    Hello

    I develop a script (in JavaScript) which will allow a user to select an export PDF presets (that are loaded in a drop-down list) and then export the InDesign file to PDF, by using the selected PDF preset.

    I have the combo fill properly and I am also able to export to PDF correctly, however I have a problem setting the preset has been selected by the user. Here are some of my code fragments:

    Drop-down list:

    with(borderPanels.add()) {

         pdfDD = dropdowns.add();

         sl = new Array();

         for (i = 0; i < app.pdfExportPresets.length; i++)

         sl.push(app.pdfExportPresets[i].name);

         pdfDD.stringList = sl;
         pdfDD.selectedIndex = 0;

    }

     

    ...

     

    myPreset = pdfDD.selectedIndex;

    In PDF format:

        // Open, Export, & Close
        for (i = myFileAmount; i >= 0; i--) {
            app.open(File(myFolderContents[i]));

            createHyperlinks();

            app.activeDocument.exportFile(
            ExportFormat.pdfType, File(myFolder.fsName + "/" + app.activeDocument.name.split(".indd")[0] + ".pdf"), false, myPreset);
            app.activeDocument.close(SaveOptions.no);
        }

    During the passage of myPreset, it is defined as 6 (the index from the drop-down list).  How can I set myPreset that the real value of what has been chosen?

    Thank you!

    In view of your code, you probably need something like:

    myPreset = app.pdfExportPresets.itemByName (pdfDD.stringList [pdfDD.selectedIndex]);

  • Make visible or invisible drop according to the value of another drop-down list. Help!

    Hello

    I need to create the following form... I want to choose at the beginning of the shape between 3 options (imagine: 'Opt1', 'Opt2' and 'Opt3'). And after that, I would like to make visible 10 different lists. I mean, if I choose 'Opt1', 10 drop-down lists related to 'Opt1' will become visible (the drop-down list together, including the text of the title and the clean drop-down list). Otherwise, if I choose 'Opt2', 10 drop-down lists related to 'Opt2' will become visible and the same 'Opt3 '.

    This problem, which seems to be very easy to resolve, it is impossible for me. I have read hundreds of forums and manuals, but I can't find the solution. I tried with several thousands of events, but I can't do the form works as I want... So, please, can someone help me?

    Thank you very much.

    Hello

    Here is an example. The script is located in the event of changing the drop-down list. The easiest way is to group your drop-down menus in subforms, then simply script for the visibility of three subforms, instead of 30 drop-down menus.

    The script focuses on the choice of the user and changes the visibility by using a switch statement. One if exposed to the exit event would work as well.

    switch (xfa.event.newText)
    {
         case 'Option 1':
              option1.presence = "visible";
              option2.presence = "hidden";
              option3.presence = "hidden";
              break; 
    
         case 'Option 2':
              option1.presence = "hidden";
              option2.presence = "visible";
              option3.presence = "hidden";
              break; 
    
         case 'Option 3':
              option1.presence = "hidden";
              option2.presence = "hidden";
              option3.presence = "visible";
              break; 
    
         default:
              option1.presence = "hidden";
              option2.presence = "hidden";
              option3.presence = "hidden";
              break;
    }
    

    Note that all three subforms are hidden in Design view. The drop-down list choice makes the appropriate subform visible.

    In design mode, you can select a subform in the view of the hierarchy and in the object/field tab change its visibility to visible, if you want to work on it in the design.

    Hope that helps,

  • Disable the AutoComplete, but keep a drop-down list of suggestions

  • move selected value in one drop-down list to another

    Hello

    I have two lists, and I wanted to make sure that people choose in the first drop-down list before selecting from the second drop-down list. What I tried to do was so, if the user tries to choose something in the second and the first list was unsuccessful, an error message appears asking the user to select from the list.

    The problem I encountered: I can't change the value in the first list to the second list to check and see if the first list got whatever it is selected. Any idea?

    First list: Department

    second list: jobs

    in the first drop-down list

    var selected = xfa.event.newText;

    second drop-down list

    If (selected == "" |) some == "null") {}

    xfa.host.messageBox ("Please select from the first menu drop-down before choosing from this list.");

    }

    Thank you

    F.

    Hello

    In the first drop-down menu script, you declare a variable "selected". This form variable lives only in this event. You can not variable accessthat other events or other objects.

    You are on the right track, but rather to test the variable in the stated case, test the rawValue of the first dropdown.

    if (dropdown1.rawValue == null || dropdown1.rawValue == "")
    {
         xfa.host.messageBox(...);
         xfa.host.setFocus("xfa.form.form1.page2.dropdown1");
    }

  • Selecting a value in a drop-down list returns to an incorrect value

    Hello

    I have a table with drop-down lists in a column. The drop-down list provides 3 values: Yes, no and s/o. When the user selects n/d and leaves the cell, the value changes to no.

    Any thoughts on what is the cause and how to fix it?

    Thank you

    MDawn

    You can set the same value for two choices in the drop-down list. This is why it is failing the first condition in the list with the same value...

    Or

    You could not give the values for the items in the list... In this case, as they both start with "N", it will highlight the first item that starts with "N"...

    Set different values for each element in the binding tab, then click on specify point values.

    Thank you

  • How to view the separate date in a drop-down list

    I know I've done this before. For the life of me I don't see what I'm doing wrong. I have an outputing to query date/time formats from a database Access in a drop-down list box select. I can't go out on double dates. I wonder if it is because the time in the database is different for each line? I want to just display an 08/09/2006, even if there are 40 of them. Here is my code:

  • Why don't I receive not all values in a drop-down list in OBIEE?

    Hello

    Why I don't receive all the data which is present in the tables.and there is no limit in the County of datas? and there at - it presents another way to get all the data in the drop-down list in the tables?

    Yes, there is an internal limit on the no. values that are displayed in the drop-down list on guests. I guess that its 256 in 10 g.

    To increase the limit, add entry in the instanceconfig.xml below:


    1000

    This will increase the limit of 1000 values in the drop-down list.

  • Adobe LiveCycle upper tiny typed value in a drop-down list

    I used to do this workaround was to make the data all uppercase and then forcing user uppercase input.
