The hide/show button with the AJAX selection list

I have the button named "QUERY" and AJAX list selection page #2 'ID'. When my selection list value is 100, I would like to display the button, otherwise hide the button. I checked the session values are defined correctly for the selection list when I change the value, but the following code in one of the messages in the forum does not work. is it different for elements of AJAX?

Added the following code to select the list - onchange = "disble_enable_button (); »

function disble_enable_button() {}
If x$ ('P2_ID') .value = '100'
x True $('P2_QUERY') = true;
for other x $('P2_QUERY') true = false;
}

Hello

function disble_enable_button() {
if ($v('P2_ID') == '100')
$x_Show('P2_QUERY');
else $x_Hide('P2_QUERY');
}

  • How to set the initial state to hide/show buttons on opening PDF files?

    InDesign offering a wonderful object multi-state capacity which unfortunately does not work in PDF files. It took a bit of research for me to come with this information, the UI program itself gives indications that this should work. (Why not maybe another forum of discussion.)

    So, I create an interactive PDF using buttons to hide/show specific paragraphs (which are also implemented as buttons because only the buttons and forms can be hidden or shown, AFAIK).

    I've set up a PDF created via InDesign using the six control keys and seven paragraphs - one of these paragraphs is the initial state that I want to see when the document is opened. As long as the PDF file that I create is distributed, that's how it works: an initial paragraph appears, buttons can be clicked and the stuff of Heroes appears the mark.

    However, a colleague thoughtfully saved the PDF file (so it could rename something more to his liking). When he does this, he left one of the displayed subsidiary paragraphs, rather than the initial paragraph I intended... and of course, this is the version that came out to the customer.

    Question: Is there a way to set the initial state to hide/show buttons when a PDF document is opened first, regardless of the State in which he could let or saved? I guess it's sort of ON OPEN event that would allow me to define an initial state as a safety net to the way I save the original document. Obviously, the PDF AS I DELIVER IT will pave the way, I want it, but I'm trying to overcome the appearance of the Murphy's law of a document that can be re-recorded in another State. An event which OPENED on that cure.

    Thank you.

    in this case you would have been better if you had locked the PDF file in order to prevent changes ANDS record as actions...

    Hello

    If you have added in the Page template, then the P39_BATES_DESCRIPTION will not work. As the P63_ATTRIBUTE_CLASS_CODE is not on the page, javascript will throw an error and that will stop the rest of the code to run.

    You can get javascript to test for the existence of a question of fact:

    if ($x('P63_ATTRIBUTE_CLASS_CODE')) {$x('P63_ATTRIBUTE_CLASS_CODE').style.display = 'none';}
if ($x('P63_ATTRIBUTE_TYPE')) {$x('P63_ATTRIBUTE_TYPE').style.display = 'none';}
if ($x('P39_BATES_DESCRIPTION')) {$x('P39_BATES_DESCRIPTION').style.display = 'none';}

  • Slight problem of AJAX selection list, I hope...

    I probably looked at all the examples that uses AJAX to fill selection lists that are out there and eventually got a job almost completely.

    In my application, I use a form on page 23 to create a folder and then also use a form on page 22 to update a record. Two of these pages, I have 2 selection lists that use AJAX to complete each other. On my page of form creation, these two select lists display properly and correctly submit a report page.

    Now, when I click on the document I just create the homepage, I get redirected to the update (page 22) page where I just submit all items are displayed correctly except the second selection list. The second selection list displays the correct list of the elements in the selection list, not the one I had just chosen. What is shown is the first option in the selection list, no matter what I had selected when I created the folder. Always the first option display anything in my code?

    Thank you

    Hello

    There are a number of issues here:

    1. remember that creation and editing features are on TWO different pages - when you refer to "the page is not save...". ' is in fact another page
    2. in the CHART table, you have an ID column AND a column RECNUM. You use the RECNUM column in the report link. In the CHART table, there are plenty of duplicates in the column RECNUM, which made it impossible for me to test - whenever I've created a new record that he got the same RECNUM value as an existing record, and I couldn't change then my new record as the process of "search...". ' incorrect 'more than one folder. You must use the ID column in the link, because it is unique
    3. on the selection of CAUSE list, you had a few items in quotes - I have no idea why. It was actually a good deal to do for your original problem. During the construction of the selection list, the value of the CASE is used as the VALUE attribute on the OPTION tag by enclosing it in quotes. What were you end up with is: < OPTION VALUE = '"sometext" ' > 'etc' < / OPTION >. The VALUE is, therefore, ""-an empty string. I removed the quotes from the data
    4. more importantly, as the CAUSE table made a unique ID column, this should be used as a return value for the list and therefore, the value stored on the CARD table. If you do this, you use the quotation marks if they are in some cases

  • Hide/show subforms with a click of a radio button

    I'm totally in this new and have very little idea what I'm doing.  I received my form to show/hide questions based on the click of a radio button.  My next question how do I eliminate the white space between issues where the subform of questions is "hiding" until the user clicks on the radio button?

    Thanks in advance to anyone who can help me with this!

    You can be the definition of property presence 'invisible '. Which is why this white space appears on the screen.

    Try to set the value of 'hidden', it will remove the space.

    If you use subform1.presence = 'invisible', the subform is not visible for the user but occupy space on the form.

    If you use subform1.presence = 'hidden', the subform is not visible for the user and also takes up no space on the form.

    In addition, the Page subform content type should be changed to be "cast" and the form should be saved as XML dynamic.

    You must do the following to make the dynamic shape.

    (1) file menu Goto-> properties of the form and select the default values tab change the default rendering in dynamic XML form Format

    (2) select the Preview Tab. Set the type of overview as a form 'Interactive form' and preview Adobe XML dynamic XML form

    (3) Finally, while saving the PDF select Save As Type 'Adobe Dynamic XML Form.

  • Point Set size dynamically the value of the corresponding select list

    Hi friends,

    Few days, before I learned a concept of change the size of the item dynamically according to the value of the selection using Jari list. I missed to ask him something (such as an extension of it).

    This is the thread

    {: identifier of the thread = 2282838}

    He produced the wonderful example below

    http://actionet.homelinux.net/htmldb/f?p=100:214:7956651650754287:NO:_

    Was that I missed in it, it possible to change the label of the element according to the selection list.

    According to the example, jari has limited the size of the element according to the selection list. Suppose that in this example if I select "China", im getting elements of different size and "India" means im get point of different size. But the labels of all the four elements are the same as

    attribute < li > 1
    attribute < li > 2
    attribute < li > 3
    attribute < li > 4

    As an extension, I need like assume that 'China' means that the label of the columns must be

    < Li > State
    < li > address
    < li > pincode
    < li > district

    If "India" is the label of the four elements must be

    < li > customers
    < Li > operators
    < li > units
    < li > provinces

    It is possible to generate different labels for the different size points, according to the value of the selection list. Since there are only four elements present in the database table.

    Brgds,
    Mini

    Hello

    Alter the table where you have point sizes and add the ITEM_LABEL column.
    Fill the column with the values you need for labels.
    Add the new column for the application process

    DECLARE
  l_sql VARCHAR2(32700);
BEGIN

  l_sql := '
    SELECT item_name,
      item_size,
      item_label
    FROM demo_item_dyn_size
    WHERE lov_value = :P214_COUNTRY'
    ;
   APEX_UTIL.JSON_FROM_SQL(l_sql);

EXCEPTION WHEN OTHERS THEN
  HTP.PRN('{"row":[]}');
END ;

    David

    Hi David,

    It is difficult to know what can happen that I can't see your page - this error message indicates that javascript can not see the page element to which you are referring to.

    For example, if I make document.getElementById("ABC").style.display, but the article did a 'BCD' ID I would get this error.

    So, the first thing to check is that the list item is the ID that you think it does. Load the page and do a view Source. Find the selection list and check to see how ID attribute there. If it contains the right ID attribute, then it might be easier if you could save the page view Source and send it to me at... so I can watch it.

  • The value of another field using the multiple-selection list

    Hello

    I have a multi select list as USER name name...

    What is your version of the database?

    If you use database 11g then you can use the following query for your condition,

    select LISTAGG(user_email, ':') WITHIN GROUP (ORDER BY user_email) from table_name
where INSTR(':'||NVL(:PX_USERNAME,user_name)||':',':'||user_name||':')>0
