Default values & javascript in tabular form manual

• Default values for the tabular report

  Hello
  
  Please forgive me if the answer to my question, there is an obvious place; I have grepped through these forums a little but you do not see a close answer what I'm looking for. My problem is that I have a tabular form and when a user clicks on 'Add the line' I want certain columns of the new line to be pre-filled, but it doesn't seem to be in any way obvious to do. Downhill report attributes don't give me what I'm looking for. I thought that the calculations would be something that would work as well, but no, that does not work either.
  
  What I want to do something fancy in the region Source section and fill in the values of the column it? Or have I missed things completely.
  
  Any help (and heckles) greatly appreciated.
  
  Thank you!
  
  Jon

  Jon:

  You need join "column attributes. Click Edit next to the column that you want a default value. Then, in the section 'Tabular form Element' choose ' PL/SQL expression or a function' for 'Default Type' and specify the default value field "Default". If your default is a string then put the value between "'". ""

• Avoid repeating the selected values on the tabular form select list

  Hello

  I need help with the following situation:

  I have a selection list containing all departments. When the user selects a Department, a tabular presentation appears with a list of selection employees containing on this Department. When adding new employees (new lines), I would like to remove the current employees of the selection list without submitting the page to avoid duplicates.

  Something similar to this: http://apex.oracle.com/pls/apex/f?p=18:307, the problem with this example is that the number of lines is predefined and initially shows all values so if I change one, it erases all existing records.

  I created an example on apex.oracle.com:

  Workspace: EDIAZJORGE

  USER name: TEST

  PASSWORD: test123

  Application: 84395 - tabular

  Page: 1 - home

  Thank you for your help,

  Hi Erick,.

  As a solution, I suggest to use an element of the shuttle in a form instead of a tabular presentation. I think that its functionality to meet your needs.

• Problems with the construction of a tabular form manually

  Hello guys,.
  
  I would ask kindly for your help. I'm having a problem with the fields on a report updateble in my APEX application.
  
  The report I have two fields that im done with the htmldb_item function. One is the ID of the record and the other attribute that can be updated using a selection list.
  
  -----
  SELECT
  htmldb_item. DISPLAY_AND_SAVE (1, "TABLE".) "ID") "ID", "
  htmldb_item. SELECT_LIST_FROM_LOV (2, "TABLE".) "ATTRIBUTE", "LOV") "ATTRIBUTE", "
  THE "TABLE".
  -----
  
  Then I have a process that needs to update the table.
  
  -----
  BEGIN
  
  BECAUSE me IN 1.htmldb_application. G_F01. COUNTY
  LOOP
  
  apex_application.g_print_success_message: = ' < span style = "color: green" > attribute: ' | NVL (htmldb_application. G_F02 (i), 0). » ID : ' || htmldb_application. G_F01 (i) | "</span > ';
  
  UPDATE table
  Attribute SET = NVL (htmldb_application. G_F02 (i), 0)
  WHERE id = htmldb_application. G_F01 (i);
  
  END LOOP;
  END;
  -----
  
  The update can't even if the loop works fine, but the success message prints only the htmldb_application. G_F02 (i) but not the htmldb_application value. G_F01 (i). But how come doesn't work OK if loop the htmldb_application. G_F01 (i) has the value null?
  
  The funny thing is, that it works on my test environment, but he behaves like this on the production environment.
  
  Has anyone else have similar experiences?
  
  Kind regards

  When I press the ADD button, a new line must be added to the shape of the table and the data should be saved to the collection. , But currently, the page is being submitted to the database table when adding new lines in the form of tables. The data should only be saved in the database when the user clicks on the APPLY CHANGES button

  I searched the Forum about this issue and have found many discussions which suggested to use JavaScript to add new lines. As I have no knowledge of JavaScript, these solutions have been strange for me.

  Please help me solve this problem.

  Thanks in advance.

  Hi Christophe,

  Follow the changes mentioned below

  1. remove this your Collections initialize

  IF :REQUEST = 'ADD'
  THEN
    APEX_COLLECTION.ADD_MEMBER(p_collection_name => l_collection_name);
  END IF;  
  

  2 condition your collection process initialize

  Modify your process-> conditions-> PLSQL Expressions->: REQUEST IS NULL

  3. create a process more onload I say Add new line to the collection

  DECLARE
      l_collection_name APEX_COLLECTIONS.COLLECTION_NAME%TYPE;
     BEGIN
        l_collection_name := 'EMAILDETAILS';
       IF apex_collection.collection_exists(l_collection_name)
        THEN
            APEX_COLLECTION.ADD_MEMBER(p_collection_name => l_collection_name);
            END IF;
     END;
  

  4 condition your Add new line to the collection

  Modify your process-> conditions-> request = Expression1-> ADD (this should be request ADD button)

  5. change your button-> Action addition-> redirect to this application page :-> page no (same page)->-> ADD APPLICATION

  6. check your through the process conditional Page collection

  Modify your process-> conditions-> PLSQL Expressions->: ASK IN ('ADD', 'APPLY_CHANGES', 'DELETE')

  7. check your subject to the process of Collection to Table under condition

  Modify your process-> conditions-> PLSQL Expressions->: ASK IN ('APPLY_CHANGES')

  8. for the whole process to remove the conditions when the button is pressed.

  If the problems persists, create a sample on apex.oracle.com and share the connection information with the name of workspace.

  Hope this helps you,

  Kind regards

• Form - different default value for each new line needed

  Hi all
  
  I'm a newbie in the APEX and now I am struggling with a problem in the form of tables.
  
  On my page, I report master detail, where the detailed part is created in a table form (I used the Wizard).
  
  Now I want to implement the following:
  
  When I click on the button that adds the line of tabular form, I want to assign the default value for the column 'LOGNO' in my tabular form. Value for this column is table extraction and I this value already stored on the page to display one element 'P210_LOGNO_ACT '.
  
  When I click on the button for one second third etc.) times I would like to set the default for the column LOGNO as LOGNO = P210_LOGNO_ACT + 1.
  
  Y at - it something simple, or is - this difficult to attribute the different value to each new row of tabular form?
  
  Version of the apex 4.1.0.00.32
  
  Thanks in advance!
  
  Jiri

  Inspect your column and find out the name of your column attribute, it must be something like fxx (f01, f02, f03... etc) and use this column instead of f11 (in my case, the name attribute is f11)

  Create a JavaScript function in your page header

  function myaddRow() {
  //perform standard addrow
    addRow();
    //set default value here
  //make sure you replace the P5_X with your page item name
    $s('P5_X',parseInt($v('P5_X'))+1);
    $('input[name="f11"]')[$('input[name="f11"]').length-1].value=$v('P5_X');
  }
  

  Change your button to add a line and call the function above, as shown below

  javascript:myaddRow();
  

  See this example of work http://apex.oracle.com/pls/apex/f?p=46417:5

• If the default tabular form when you add line

  Hi guys,.
  
  
  I had a tabular presentation where I need to set a default 1 value in one of the fields that I click on Add a line. I have no idea how to reference the element in a table via JavaScript.
  
  Despite this, Add a line already button calls a javascript function to add a line, do not think its possible to use javascript here.
  
  Any suggestions how can I achieve this?
  
  Thank you very much.

  Can't you just change column attributes > tabular form attributes > type default PL/SQL Expression or a function > as the default * '1' *.

  This should add the value 1 to add when you click line

  You can use JavaScript, but why worry if it's easily achievable

• What should I do for default values when a new line is created in a tabular presentation?

  Hello all-

  I have a tabular presentation that requires a few columns to be entered by the user when he or she creates a new line, but other fields in the column can just default to certain values.  How to set these values by default so that the user doesn't have to be bothered with enter no data except those which MUST be entered?

  An example:

  Form1

  CITY OF COUNTRIES IN THE REGION

  APAC JAPAN TOKYO

  SIDNEY AUSTRALIA, APAC

  APAC KOREA-SEOUL

  REGION is almost always APAC, then I want that by default.  The user can always adjust if necessary, but I want to put it to the user, only to save having to enter a value.  When the user clicks on the button to add a line, that I want to load this value immediately and leave the two empty fields so the user can enter what they want.

  Thank you!

  John

  Hello

  Go change this column.

  Under attributes of tabular form, you will find options to set the default value

  Kind regards

• Setting value using javascript on the form of tables created by APEX_ITEM

  I can assign the value using javascript on normal form of table as below:
  
  var vRow = pThis.id.substr (pThis.id.indexOf ('_') + 1);
  $x_Value ('f05_' + vRow, 'Value');
  
  However I can't do the same if the tabular presentation is dynamically created by APEX_ITEM.
  
  Some tips on how to do this?
  
  Thank you

  If this should not be something like:

  this.id.substring(4, 8)

• If the default value in columns on slot form of table does not work.

  Hello
  
  I created a tabular form and I want to set some default values to columns that are based on the values of page elements.
  
  so I put the page element to the value of the column in the attributes in a table by selecting the value & P24_ISSUE_ID. default type as Expression PLSQL & DEFAULT function there but
  in the same way, I tried for the other column by selecting the type default as pl/sql expression and function by default the value & P24_CASE_NAME.
  
  but it throw an error of this type could not parse the SQL query: ORA-00904: "C254DB": invalid identifier
  
  I don't understand where I did wrong, I checked for the data types of columns, all right.
  
  so please help me out of this problem.

  for the first column

  I chose

  As the default * & P24_ISSUE_ID.* it is a number data type column

  2nd column

  The default Type as PL/SQL Expression & function

  As the default * & P24_CASE_NAME.* it's column of type Varchar2.

  Element (name of the page element or application) for the default Type and the name of the default item ( P24_ISSUE_ID, P24_CASE_NAME etc.) options appropriate for a default value for a page element.

  * & P24_ISSUE_ID.* is not a "PL/SQL Expression or function.

  but it throws an error, because this guy could not parse the SQL query: ORA-00904: "C254DB": invalid identifier

  What you're doing results in the engine of the APEX, P24_CASE_NAME 'C254DB' value in the default value and then try to assess this string as a piece of PL/SQL. Outside a block in which it is defined as a variable, constant, or a function 'C254DB' is not a valid expression of PL/SQL.

• Spry form validation Date with default value error

  The spry form validation below was created with DW CS6

  I created an HTML form and displayed with PHP to a MySQL database.  One of the lines of form is to enter a date.  This line uses a 'out of the box' sprytextfield data validation without changes to its CSS or JS:

  HTML

  < span id = "sprytextfield1" >

  < label for = "servComDate" > Date beginning? < / label >

  < input type = "text" name = "servComDate" id = "servComDate" >

  < span class = "textfieldRequiredMsg" > a value is required. </span >

  < span class = "textfieldInvalidFormatMsg" > Invalid format. </span >

  </span >

  < script type = "text/javascript" >

  var sprytextfield1 = new Spry.Widget.ValidationTextField ("sprytextfield1", "date", {index: "00/00/0000", format: "mm/dd/yyyy"});

  < /script >

  On request, the form value is captured via PHP and date format is converted to a format of MySQL before entering in the database.

  PHP

  $servComDate = date ("Y-m-d", strtotime($_POST['servComDate']));

  It all works perfectly.

  Now, I created another page with a HTML form to change information.  First, PHP takes the field in the database and converts it to MySQL format to the format used in the sprytextfield above, in which it was created.

  PHP

  $servComDate = strftime ("% m/%d/%Y", strtotime ($row ["servComDate"]));

  Then the HTML form is filled with existing value

  HTML

  By filling in the form with existing value appears with the right in the box format, it shows these 'mistakes ':

  value is required. Format invalid.

  As I said above, I have not changed the CSS or JS that is loaded with the Spry textfield, so I don't get that here.

  I'm obviously something wrong with pre-filling a Spry textfield with a default value.

  What is the real need have a default value on a Textfield of Date Validation Spry?

  Thanks in advance!

  Make sure that, in the page change the constructor looks like

  var sprytextfield1 = new Spry.Widget.ValidationTextField ("sprytextfield1", "date", {index: "00/00/0000", format: "mm/dd/yyyy"});

  The following works fine for me

• Default values for form

  I am building a form for my office that submits information to a database.  I would like to use the same form to add new information and modify existing information.  I also want the form to retain the data once it is submitted (i.e. If the user clicks on send and there is a required field blank, the form is re-load with the stored data.)

  I'm not allowed to use javascript (the agency rule).

  I started with something like this for each field:

  <cfinput type="text" name="title" value="#FORM.title#" />

  That's fine, but then I added the Edit option.  A photo of the user entry on a previous page that transmits an id number in the URL (ex: form.cfm? edit = 32) to the form.

  When URL.edit has one value other than zero (default assigned cfparam), it triggers a query that retrieves data from the database.  I want these data to fill in the form, so I tried this:

  <cfinput type="text" name="title" value="#iif(URL.edit eq 0,DE(FORM.title),DE(queryname.title))#" />

  This works perfectly if the query is run, but I get an error when I load the blank form:

  Element TITLE is undefined in QUERYNAME. 
  

  I'm basically train make empty if the form is loaded from scratch, the default value of form make the previous form values if the form is re-charge after submission, or and use the query if a URL parameter is passed.

  Is it possible to make this work?  I don't want to have to write several versions of the form.

  Your half-way, you have just basiclly need to combine your two approaches.

  Set a collection of variables to fill the fields of the form.

  Then if there is a query is run, set this collection with the values of the query.  It is roughly as follows, and there are different ways of this skin for apporached different framework.

• Default value for the text in a tabular presentation element

  Hello
  
  I creates a tabular form generated by using a SQL query.
  I would like to first of all the value for a column of nextval deault a sequence when an empty row is added using the add a LINE button
  
  my request currently for the sequence value column when you click on the ADD row button is:
  apex_item.display_and_save (4, NULL) as trans_id,.
  
  I want this column trans_id trans_seq.nextval where trans_seq is a default sequence.
  
  I tried specifying the default value in the column attributes (expression of PL/SQL - trans_seq.nextval) which does not work.
  If I give in the SQL query, it throws an error saying that the unauthorized sequence here...
  
  My query is structured as follows:

  SELECT
  apex_item.display_and_save (4,c002) trans_id
  FROM
  apex_collections
  WHERE collection_name = 'TRANSACTIONS'
  UNION ALL
  SELECT
  apex_item.display_and_save (4,NULL)  as  trans_id
  FROM DUAL
       WHERE :request = 'ADD_ROW_MANUAL'

  Appreciate any help in this regard. I hope that my question is explained clearly
