• Passing values from one page to the other

  Hello

  I have two code coldfusion pages, a page how to display the form and another is the action of the form code. I want to create another page, so that if the user hits the edit button, it is taken to a page where the user of the same form with entries filled beforehand for some areas and the remaining fields are uneditable, i.e. they give the value in the database for the current entry, as it is.

  Should I access the values of the database, if so, HOW? And if not, HOW?

  Thank you

  vijayvijay77.

  IF you aready accessible data on the previous page, you can store the data in a persistent scope (session, application, server) where it can be reused on other pages without a trip back to the database.

  IF you have not yet accessed the data, then passing a key via a GET (URL alias) or variable POST (aka SHAPE) allows easy access to a query to retrieve the desired data from the database to fill in the form.

  The use cases have good discussion with examples in the ColdFusion Developer Guide.

• Passing the value from one page to the other page

  Hi gurus,
  
  I need to pass the value from one page to the other page and two pages use different AMs.
  In the first page I have sellers results region table where the $vendor_name column is a hyperlink that navigates to the page Vendor_Sites. Now after accessing the second page, I want to excute the VendorSitesVO in PR of CO based on the value passed to VendorsVO (vendor_id) of first page.
  
  can someone help me on this?
  
  Thank you
  Vincent.

  You can set parameters of Pagecontext and transmit values through them. These values can be passed between pages, even if the AMs are different.

  Try:
  pageContext.putParameter ("Parameter1", value1);
  pagecontext.setForwardURL (second page)

• Passing the value from one page to the other

  Hello

  I'm trying to display a page popup with an IR as below.

  1. There is a field next to a button.

  2 at the click of the button I want to get an Id and the value of a text field for step 1 on page popup and use them as a filter condition.

  3. I wrote a dynamic action that has the consequence of the "real" actions

  "a. the with action run PL/SQL code", which affects the value of the url a hidden point as below

  : P111_SHOWLOCATION_URL: = APEX_UTIL. PREPARE_URL ('f? p = & APP_ID.:112: & SESSION.: P112_PICKLISTID, P112_QUANTITY: & P111_PICKLISTID, & P111_QUANTITY.');

  "b. action run Javascript code" that displays an alert for one blank on the other shows the popup

  If {(apex.item("P111_QUANTITY").isEmpty ())}

  Alert ("Please enter the quantity to show locations.");

  }

  else {}

  popUp2 ($v ('P111_SHOWLOCATION_URL'), 700,300,0, 0);

  }

  When I change the value of the field in step 1 and press the button. There are only the old value not the new value. What's wrong with this code?

  I think you need to spend time by reducing your code at a practical level.  You seem to be any passage in the book in each function and I think that probably none of this is necessary.  If you have declared these variables at the beginning, then you don't need to transfer them to any function, because they are gobally available to one of the functions/code that follows.  Similarly, if you have some textfields on stage, it is pointless to pass those in all functions for the same reason.

  I see you doing the overuse of 'delete' (and possibly errant use as well).  Is probably the only thing you might want or need to use...

  delete Subjectxtimer_mc.onEnterFrame;

  Which stops the enterframe trigger activity, which I think is used to update the textfields which indicate the time.

  And that conditional uses == Nan is not likely to do anything except wonder what is a Nan.  TextFields hold the strings, which are cited.  SO unless you have a variable named Nan somewhere that has a value of string assigned to her, this condition will do nothing for you.  You probably don't need it at all if you get this working properly.

• Passing variable from one page to the other

  Hello
  
  I'm probably missing the boat full of something because I tried everything I found on this forum and it still does not work. I am trying to pass a value entered in a text field (Item = P1_TXT_1) on page 1 to page 2 when I click on a button. The button is configured with the URL redirection as an option to the Page 2 with the "game of these values (P1_TXT_1) with these values (& P1_TXT_1)." In the end, I use this variable in a query in report on page 2 (emplid =: P1_TXT_1).

• How to pass values from one stage to the other

  I have two steps (called primary and secondary). The primary stage creates the secondary stage. When the school is open I can access all the members (say according to) of the 1st stage and try to set a value. But in the 1st stage, I think the value is not defined. I think it is because 1 is executed before the 2nd. I used showAndWait() in 1st then show() on 2nd, then it is thrown exception.
  
  So I want to use the values defined by the 2nd step of the 1st stage.
  How to synchronize their?
  Thank you.

  You can use showAndWait() on your secondary stage. Then execution is blocked, and you will see the change in your variable:

• Moving objects from one page to the other

  Hi all

  I need to move an image from one page to the other...

  For example, on page 1, I have an image that he be shifted to page 5 of the document. Is this possible?

  Vandy

  Click the page 1 picture to select it and run it:

  var doc = app.activeDocument;

  var r = app.selection [0];  'r' is the graphic image containing the image

  r.Move(doc.pages[4]);          on page '5 '.
