• custom JavaScripts at the APEX of the upgrade from 3 to 4

  Hello
  
  I'm referencing external javascripts in my APEX 3.2 applications. Now, I plan to upgrade the engine of 3.2-to-4.0.2.00.07 APEX. I want to confirm the following:
  
  1. I use the following lot. He will work at the APEX 4? It is appropriate to use html_GetElement('pFlowId').value to APEX 4?
  get < pre > var = new htmldb_Get (null, html_GetElement('pFlowId').value, 'APPLICATION_PROCESS is?', 0); < / pre >
  
  Can I create JavaScript code following in Page 0 to make it work at the APEX 4?
  
  < pre >
  function doSubmit (pWhat) {}
  Apex. Submit (pWhat);
  }
  < / pre >
  
  2. I use "doSubmit('???');" a lot. Should I change it to "apex.submit('???');" after that I upgraded APEX 3 to 4?
  
  3. when I call JavaScripts to report or select list, I always use the javascript: Pseudo-protocole. For example, it can be like onchange = "javascript:doWhat();" ». Is javascript code: necessary for the APEX 4 Pseudo-protocole?
  
  Thank you.

  1. I use the following lot. He will work at the APEX 4?

  Yes. He included in the library of apex_legacy_4.0.js for compatibility with.

  It is appropriate to use html_GetElement('pFlowId').value to APEX 4?

  N ° it has been replaced by the $x and $v methods and the inclusion of jQuery.

  It has NEVER been necessary in the attributes of the event. That's all just wrong.

• the JavaScript in the Apex 4.2.4 file storage

  Hi all

  I'm a little confused about the JavaScript files are stored in the (4.2.4) Apex.

  Oracle said that we can call a JavaScript file from the Page template:

  

  Oracle speaks of CALLING here, but he said nothing about WHEN the .js file is actually stored.

  Therefore, the link so that it is the folder/my_images /...

  But where is this file? Isn't that the same as #WORKSPACE_IMAGES #, where I put my CSS files?

  Thanks in advance for your clarification.

  Thanks in advance for your clarification.

  They (Oracle APEX Dev Team) has documented how to integrate javascript into your APEX application

  Reference: http://docs.oracle.com/cd/E37097_01/doc.42/e35125/bldapp_js.htm#HTMDB05013

  Now, where store the JS/CSS/IMAGE files is your concern. You have three options for this:

  • #WORKSPACE_IMAGES # - components - shared static files, not associated with the request.
  • #APP_IMAGES # - components - shared static files associated with an application
  • #IMAGE_PREFIX #-the path of the file corresponds to images virtual directory Viz/i /. The storage of the files depends on the web server you are using: ADR/OHS/EPG.

  Reference:

  • "IMAGE_PREFIX", "APP_IMAGES" and "WORKSPACE_IMAGES".
  • http://docs.Oracle.com/CD/E37097_01/doc.42/e35125/ui_file_manage.htm#HTMDB06011

  As a general rule, I did the following to the js/css files:

  • If your js/css file is the specific page, upload it to the shared components and also it is especially Page attributes-> section Javascript / CSS-> file URL

  For example:

  #APP_IMAGES#my_custom_page1.js
  

  • If your js/css file is required in the entire application, transfer on components/web shared server (Pictures folder) and include this is the reference in the Page template.

  NOTE: I prefer to keep level application files as well in shared components like this help to application deployment.

  As an APEX 4.2 update it is another option refer you js/css files application (instead of changing the page template), Application-> shared-> attributes of User Interface components. You can consult the js/css files in the sections for 'File URL':

  For example:

  #APP_IMAGES#custom.js
  

  I hope this helps!

• How to check if the! = null fields in coumn 2 have some value

  I have a form with a table that is 15 x 9.

  In column 2, if the! = fields null == 300 & & anyone of the! = null fields is not 300, I need an error message saying all = 300.

  If all of the! = null fields are == 300 then no message

  If none of the! = null fields = 300 none the message

  But there is no need to change the values, simply display a message.

  Thanks in advance

  I don't know how you have labeled him your lines. Here is my solution, if there is just a line repeated, all named Row1.

  

  If the lines are already created and appointed line1, line2, etc., then it would look like this:

  

• Reduce the width of the apex element field...

  I can't reduce the width of the apex element field. I used apex_item.text in the region of select query report.
  
  I want to change the field width. I tried to change the width of the element... but no use. pls help how to change.
  
  
  Thanks and respect,

  The third parameter to apex_item.text is p_size. You can set the width of field with this setting.

  Ok. Take a look now. I used the function TRIM as shown above and also changed the comparison for questions 3 text based on ' if: p1_question_with_text is null'

  Seems to work now

• JavaScript - fill out the text field with data entered

  Hello

  I am learning javascript and need help to put in place a script that will do the following:

  I have three text fields where users enter data. I would like to take this data and provide a summary in a 4th text field. If a field is null, it should be ignored.

• Find the null field

  I have a FormCalc script that checks to see if TextField1 == 2 TextField and if he then set a value of 1, if they are not equal, then 0.

  However, the shape is setting the value to 1 even if there is no entry in each field. I think I must include an expression in the formula indicating whether fields are null do not set a value. I don't know how to do this. Can anyone help?

  Thank you

  MDawn

  replace "! ="with"No"in your code...

  ! = is a javascript notation.

  isn't a FormCalc rating...

  Thank you

• MySQL Null field

  We change the database uses our Web site MS - SQL for MySQL, and within the framework to test, I found that the piece of code will give an error "Incorrect integer value: for the GraftYear column ' if the user do not type anything for the value of a year of transplant, which is optional.
  
  < cfquery name = "insertblocks" >
  INSERT T_Block (season, KPIN, Blockname, GraftYear, CreateDtTm)
  VALUES)
  < cfqueryparam value = "#request.season #" cfsqltype = "cf_sql_varchar" maxLength = "4" >.
  < cfqueryparam value = "#attributes.kpin #" cfsqltype = "cf_sql_integer" >.
  < cfqueryparam value = "#UCase (Trim (blockdetails [1]))" # "cfsqltype ="cf_sql_varchar"maxLength ="30">,"
  < cfqueryparam value = "#blockdetails[5]" # "cfsqltype ="cf_sql_varchar"maxLength ="4">,"
  #CreateODBCDateTime (Now ()) #)
  < / cfquery >
  
  It works very well with MS - SQL, which inserts the value 0 when it is passed an empty string, which is what I think happens here in this case. When I do a manual insertion on the table with an empty string, then MySQL stores a zero even as Ms. I know I'll have similar problems with other parts of the site, so I wonder if there is a reason why this is happening. The table is configured to allow null values in this field, and the default value is NULL. Should I set the default zero perhaps?
  
  Any help much appreciated...

  > Incorrect integer value

  On the one hand, if GraftYear is a "whole" the cfsqltype must be cf_sql_integer not "cf_sql_varchar". Similar comments about the column cfsqltype CreateDtTm. Should not be cf_sql_date, cf_sql_timestamp, etc.?

  If you want to insert a 0 when the variable is an empty string, you can use the val() of CF. It converts a non-numeric values to 0. If you want to insert a NULL value when the value entered is not numeric try using a conditional test in the attribute "null."

• Tutorials for HTML 5 and Javascript to use APEX 5

  Hi guys,.

  Ask any good ebook or online tutorial where I can learn how to use HTML 5 and Javascript with APEX 5.

  Thank you

  Hi edy12,

  HTML5 is already used in some of the themes in Oracle APEX 5. (namely HTML5 themes introduced in APEX 4.2 + universal theme in APEX 5.0)

  Learning HTML5 and JavaScript, there are a lot of online resources like this:

  • HTML tutorial
  • JavaScript Tutorial

  Also, you will find good books for HTML5 and JavaScript. In addition, having learned HTML and JS, you can navigate on jQuery and CSS tutorials like these two are also needed to develop applications APEX 5. As these (HTML, JavaScript, jQuery and CSS) are web development of basic technologies, learn which will give you good understanding about the structure and behavior of the HTML page and edge to customize themes and templates in your APEX application.

• JavaScript callback on apex.submit)

  Request Express 4.2.2.00.11

  
  

  What I'm trying to achieve:

  • When an I click on a link, the current page must be submitted then after loading open the link in a new tab.
  • Basically I want to simulate when the user clicks a tab, but instead open to a new page.

  
  

  What I've done so far:

  • I've read about Javascript callback and failed.
  • The link:

  <a href="javascript:doSomething(2);">MEMBERSHIP</a>

  • Functions in js:

  function submitAndGo(pageNo,callback){
    apex.submit();
    if(typeof callback == "function")
    followLink(pageNo);
  
  function followLink(pageNo){
    var url = 'f?p=&APP_ID.:'+pageNo+':&APP_SESSION.::&DEBUG.';
    var win = window.open(url, '_blank');
    win.focus();
  }
  
  
  

  • What's happening:

  When I click the link it automatically opens a new tab without waiting for the home page to finish loading (always present).
  

  I managed to do work with javascript. Here's how I did it:

  The edited link:

  MEMBERSHIP
  

  The edited js function:

  function followLink(pageNo){
    var url = 'f?p=&APP_ID.:'+pageNo+':&APP_SESSION.::&DEBUG.';
    var win = window.open(url, '_blank');
    win.focus();
  }
  

  I added a selection list with this name: P1_PAGE_SUBMITTED with static values 1 and 0.

  I also added this:

  $( document ).ready(
    function() {
    var item = $x("P1_PAGE_SUBMITTED");
  
    if(item.selectedIndex == 0){
    item.selectedIndex = 1;
    apex.submit();
    }
    else{
    alert(item.selectedIndex);
    }
  
    }
  );
  

  Now I can follow the link

  I needed the home page to submit everything first as Page 2 (membership) requires a few items on the main page.

  The membership tab has already worked for me, but I wanted to add this feature to my users.

• Apex number field. Format mask. Customize the message.

  DB 11g

  Apex 4.2

  Theme 25

  I have some number with format 999G999G999G999G990D00 mask fields. For example a field as 'special delivery '.

  It works very well. But if I get a few alphabetic characters, it gives the error message "Special Delivery Charge does not match the 999G999G999G999G990D00 of format number (example: 1,251.49). .

  Is it possible to customize this message.

  Thank you.

  Or the most elegant way to keep the number format and just 'translate' the exact text message in shared components - SMS - create a new one with the name of: APEX. NUMBER_FIELD. VALUE_INVALID2

• SCSI address and null field problems when adding disks

  I had a spreasheet and requires up to 6 drives to be added to a list of virtual machines.

  vmname hdd1, hdd2, hdd3, hdd4, and hdd5, hdd6. I then want to run another command if hdd2 is lets say its to return "two disc exists."

  HDD1 must always be mapped to scsi 0:3.

  HDD2 must always be mapped to scsi 0:4 etc..

  but some time ago a hdd1 and a hdd3 and hdd6 but no hdd2 or hdd 4.

  I have two problems

  I don't know how to make sure the player is assigned to writing scsi address.

  I know how to do or not to do things if the fields are null or not.

  Help, please.

  You can specify a SCSI nummer if you add a drive hard using the vSphere API:

  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $spec.deviceChange = New-Object VMware.Vim.VirtualDeviceConfigSpec[] (1)
  $spec.deviceChange[0] = New-Object VMware.Vim.VirtualDeviceConfigSpec
  $spec.deviceChange[0].operation = "add"
  $spec.deviceChange[0].fileOperation = "create"
  $spec.deviceChange[0].device = New-Object VMware.Vim.VirtualDisk
  $spec.deviceChange[0].device.key = -100
  $spec.deviceChange[0].device.backing = New-Object VMware.Vim.VirtualDiskFlatVer2BackingInfo
  $spec.deviceChange[0].device.backing.fileName = ""
  $spec.deviceChange[0].device.backing.diskMode = "persistent"
  $spec.deviceChange[0].device.backing.split = $false
  $spec.deviceChange[0].device.backing.writeThrough = $false
  $spec.deviceChange[0].device.backing.thinProvisioned = $false
  $spec.deviceChange[0].device.backing.eagerlyScrub = $false
  $spec.deviceChange[0].device.connectable = New-Object VMware.Vim.VirtualDeviceConnectInfo
  $spec.deviceChange[0].device.connectable.startConnected = $true
  $spec.deviceChange[0].device.connectable.allowGuestControl = $false
  $spec.deviceChange[0].device.connectable.connected = $true
  $spec.deviceChange[0].device.controllerKey = 1000
  $spec.deviceChange[0].device.unitNumber = 5
  $spec.deviceChange[0].device.capacityInKB = 1048576
  
  $vm = Get-VM -Name MyVM
  $vm.ExtensionData.ReconfigVM_Task($spec)
  

  The above code adds a hard drive with number 5 on the SCSI to a virtual machine called MyVM. The line:

  $spec.deviceChange[0].device.unitNumber = 5
  

  sets the number of SCSI to 5. A value of 0 in the number 0 SCSI: 5 is defined by the SCSI controller. So if you have a SCSI controller then the first number will always be 0.

  I don't know what you mean with "I know not how to do or not to do things if the fields are null or not.".

• problem using Javascript window.open Apex 4.2

  I'm trying to use javascript to open a new window in Apex 4.2

  When the user clicks a button on the item, I want to open the page in a new window

  That's what I coded:

  On the button

  under "the ACTION ONCE the BUTTON has been CLICKED" I select "redirect url".

  then enter this: javascript: window.open ('f? p = A:P: & SESSION.) ") ;  where A is the number of the application and P is the page of the application

  This method works.

  Click the button and a new page opens

  the problem is that the old page; the one I was on, disappears. It becomes a blank page with "[object]"displayed in the top left corner, nothing else on the page.

  Is there another way to do this?

  Try wrapping it in a vacuum similar to this:

  JavaScript:void(Window.Open...);

  or to add with

  Returns false;

  as

  JavaScript:Window.Open (...); Returns false;

• JavaScript for one of several fields to set a variable/indicator

  I need help to create a script that will read in several areas, and if one of them meets a condition (say, 'Yes'), then Checkbox1 is checked.

  The pseudocode would be:

  If Field1 is Yes

  or if Field2 is Yes

  or if field3 is Yes

  or if Field4 is Yes

  then Checkbox1 = checked

  Thus, a 'yes', one of these fields generates the check in the box.

  The other part of it is if someone were to set fields 1-4 " Yes", then again on 'No', I need a script that checks all four fields and if they are all the 'no', then affects Checkbox1 unchecked.

  I can't code, but I know how do I change/add an existing script.  I really appreciate any help.

  Hello

  Maybe something like this JavaScript code in the case where the field check box, calculate

  If (Field1.rawValue == "N" & Field2.rawValue == "N" & Field3.rawValue == "N" & Field4.rawValue == 'No')

  {

  this.rawValue = "0";

  }

  on the other

  {

  If (Field1.rawValue == "Yes" |) Field2.RawValue == "Yes" | Field3.RawValue == "Yes" | Field4.RawValue is 'Yes')

  {

  this.rawValue = "1";

  }

  on the other

  {

  this.rawValue = "0";

  }

  }
