How to use Javascript to loop through a tabular presentation

APEX: 4.2.3

DB: 11 GR 2

Requirement:

I have a master form / retail. We will see that master is the order information; Detail is the order lines. Detailed form is tabular

The detailed form, there is an attribute called 'Line Order Qty' and the user can update this field.

User can update all rows in the detail forms and change "line Order Qty' for each line. When the user click on 'Save' button on Master form, I have to do below:

Sum of the 'line Order Qty' for all lines, and compare it to another field called 'Plan Order Qty' on the master shape.

If sum 'Line Order Qty' > "Plan Order Qty", then it should appear a message with "Are you sure?" with two buttons on the message: OK and cancel.

If users click on 'OK', the application will proceed and update another field called 'Sum of Order Qty' on the main form and the value set for the sum of "Online Order Qty" for all lines;

If the user clikc 'Cancel', the application will be paused. The user must come back to change "Line Order Qty", and then try again

given, I need a popup message when the validation, I think I have to write javascript; However, in the javascript code, I need complete all lines in detail (tabular form) to get the

The sum of the 'line Order Qty'. Then I can compare the value and to launch the pop message if validation has failed?

By reading this thread: building the perfect beast: Oracle APEX - Soft Validation using dynamic measurements

I think I need to create a reference for action (DA) dymaic Javascript expression; However, in Javascript, how do I browse a table?

Yet once, I need an example of using Javascript to browse tabular forms in the form master / detail.

I don't know that my question should be raised before; but I can't find a good match of thread.

Thank you!

Hi Kevin Zhang,

Sum of the 'line Order Qty' for all lines, and compare it to another field called 'Plan Order Qty' on the master shape.

If sum 'Line Order Qty' > "Plan Order Qty", then it should appear a message with "Are you sure?" with two buttons on the message: OK and cancel.

If users click on 'OK', the application will proceed and update another field called 'Sum of Order Qty' on the main form and the value set for the sum of "Online Order Qty" for all lines;

If the user clikc 'Cancel', the application will be paused. The user must come back to change "Line Order Qty", and then try again

given, I need a popup message when the validation, I think I have to write javascript; However, in the javascript code, I need complete all lines in detail (tabular form) to get the

The sum of the 'line Order Qty'. Then I can compare the value and to launch the pop message if validation has failed?

Follow the steps below

Step 1: Change your page - > function and declaration of the Global Variable-> to insert the code below

(i) f06 is here, the column on which I am looping the f06 column and enters the total variable to the value change in the values of the row that is changed by the user.

(II) also replace your column with f06 markup on which you want to loop and calculate the total

(III) assuming that P6_ITEM is the point where you plan_order_qty, replace with your article.

(IV) SAVE this demand is what happens when OK is clicked, assign the request to process.which you give the floor to a click of the button SAVE the

function update_order_qty () {
  var line_order_qty_tot = 0;
  $("input[name='f06']").each(function() {
    line_order_qty_tot += parseFloat($(this).val().replace(/,/g,''))||0;
  });

  var plan_order_qty = apex.item( "P6_ITEM" ).getValue()

  if (line_order_qty_tot > plan_order_qty) {
      apex.confirm('Are you sure?', 'SAVE');
  } else {
      apex.submit( 'SAVE' );
  }
}

Step 2: Edit the page-> Execute when loading the page-> to insert the code below

\\calculate the total on change
   $("input[name='f06']").change(function(){update_order_qt();})

Step 3: Change your button Save and put under the Action when the button is clicked

Action: Redirect URL

Target URL:

javascript:update_order_qty();

Hope this helps you,

Kind regards

  • How to use a FOR LOOP to create multiple forms?

    I use Adobe animate CC (formerly Flash Professional CC) and I am trying to adjust the following snippet so that it creates several rectangles:

    var form = createjs new. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,100,100));

    this.addChild (shape);

    I then set it and put it in a loop I thought work in the reproduction of the form. The following code creates only a rectangle well?

    for (i = 0; i < 10; i ++) {}

    var i is new createjs. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,30,30));

    this.addChild (i);

    Move so that they do not lie on the other

    This.x += 50;

    }

    I think that the problem is how you use your iterator variable. In your loop, at the first start, i is equal to 0, then you immediately replace 0 with an instance of the Shape class, which means when he tries to loop again, I is not less than 10. They can't, because it is now a shape, not a whole number.

    Try this inside the loop:

    newshape var = new createjs. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,30,30));

    newshape.x += 50;

    this.addChild (newshape);

  • How to insert a color picker in a tabular presentation

    Is it possible to insert a color picker in a tabular presentation? I see that switch of dates is an option, but not of color chart. I would use the native widget, rather than having to load a plug-in or javascript external, if possible.

    JScolor is an interesting option.

    Just include the library and give your options and the correct class entry field: http://jscolor.com/try.php

  • How to use javascript or formcalc to reference the child controls (no name)

    Hello world

    I've created a ton of reports in the past, and I am now looking to create some reusable objects so that other people can use features of advanced form without having to learn to use scripts.

    A lot of the coding was done using this, .parent, etc. so that they can rename controls and subforms without having to worry about breaking the scripts. A question that I have is that some of my code looks at the child controls and refers to their name (for example, I have a code that uses setfocus to move the user to the first field of a subform).

    In most languages, there are ways to refer to child controls through an indexer or an array of elements or children. i.e. Subform.items [0] .rawValue.

    I know that this would cause some problems, but I think I could sort it out, if I only knew where to start. Is it possible to reference a child control without a name?

    Thanks for your help!

    -Scott

    Hi Scott,.

    The subform has a collection of nodes, you can run a loop though, as you suspected him.  If could show more than you want, but you can test the className to see if it is a field, then ui.oneOfChild.className to the type of the field. Then;

    for (var i = 0; i)< subform1.nodes.length;="">

    {

    var n = Subform1.nodes.item (i);

    Console.println (n.className + "" + n.name + "" + n.ui.oneOfChild.className);

    }

    I hope this helps.

  • How to use Javascript to populate a text field based on a selection in a drop-down list?

    Greetings,

    I have virtually no experience with JavaScript and I'm trying to find a way to add some functionality to basic Automation to a form of Adobe.  I have a drop down box called "Hospital_Name" which will contain about 7 possible selections.  When the user makes a selection, I would like to have the field of text (called "Hospital_Address") under the drop-down list fill with the corresponding address to the selection.  I have the "Hospital_Address" text field set up for multiple lines and want the address to have a line break between the address and the city/province/postal code.

    For example, if the user has selected "Hospital 1", the text field would display:

    123 main St

    Anytown, CA 12345

    Help or you can provide examples would be greatly appreciated.

  • How to use arrays and loops in the loading multiple Images?

    I am struggling to load a sequential array of images appear as a moving image. Therefore, when you click the load images one after another.

    The code below is what I have so far, but he is unable to do what I want, that there is only a single loading image, which is the last image in the table, then, either because the images are stacked on top of each other, either because I just don't understand not the basics...

    And I'm not clear on what you said kglad, that my solution will be more complicated because I need to preload my image sequence and then use a loop to load it?

    import flash.net.URLRequest;

    import flash.display.Loader;

    var int count = 0;

    var imageArray:Array = ["1.jpg", "2.jpg", "3.jpg", "4.jpg", "5.jpg", "6.jpg", '7.jpg',

    "8.jpg", "9.jpg", "10.jpg", "11.jpg", "12.jpg", "13.jpg"];

    for (var i: uint = 0; i < imageArray.length; i ++) {}

    var btn:YourButton = new YourButton();

    BTN. Ivar = i;

    addChild (btn);

    BTN.x = 0;

    BTN.y = 0;

    btn.addEventListener (MouseEvent.CLICK, clickF);

    }

    var ldr:Loader = new Loader();

    addChild (ldr);

    LDR.x = 20;

    LDR.y = 20;

    function clickF(e:MouseEvent) {}

    LDR. Load (new URLRequest ("D:/flash cs5.5/image_sequence/twirlSeq/"+imageArray[e.currentTarget.ivar]));

    }

    function loadComplete(e:Event) {}

    first process image loaded, then...

    Count ++;

    if(Count < imageArray.Length) {}

    loadCurrentImage();  Load next image

    } else {}

    Sequencial full load, continue to the next activity

    }

    function loadCurrentImage() {}

    LDR. Load (imageArray [Count]);

    ldr.contentLoaderInfo.addEventListener (Event.COMPLETE, loadComplete);

    }

    }

    count 2% alternates between 0 and 1 as increments count.  which allows to load in ldr0 then ldr1 and then ldr0 etc.

    in this way the scene still has an image instead of flashing white between the charges that you would see if you used a loader.

  • Can you create Destinations named by using JavaScript?

    I am creating a menu option in Adobe Acrobat that uses JavaScript to parse through a large pdf document and create named destinations by using the titles in the document.

    The titles all follow the same format unique, so I am able to identify them using regex. Once I found a title, I identify also the page it's on--and I store several times the title and the page in a table.

    My plan was to create named destinations using the information stored in the array. However, I did have a lot of chance to find how to create destinations named with JavaScript.

    Any input would be appreciated.

    No T_ROWNUM2 should be 0003.

    I made a copy of your page to make corrections.

    There are several problems.

    First you where submiting T_ROWNUM2 whereas you would use: t_rownum in the pl/sql code.

    I changed the name of the element in the f_set_multi_items_tabular2.

    Secondly you where now affecting the rownumber f03_0001 for the first line.

    I changed the following text in the show_lov.

    var point = s.substring (4.8);

    var Field2 = item;

    I also had a compilation of pl/sql code error, there was a); missing the end of the last item. Fixed that too.

    But why do you think lpad won't work for lines 10 and more.

    LPAD ('10', 4, '0') will give "0010"

    LPAD ('100 ', 4,'0 ') will give "0100"

    LPAD ('1000 ', 4,'0 ') will give '1000'

    So unless you have more than 9999 lines you would have no problem.

    I have a lot of script transformation to search for text "signature of the employee" on each page in a multiple page and file for then the list in the console all pages that do not have the text of the "Signature of the employee" included.

    The script is still functional as one if statement must be included.

    Can someone advise please how to use an if statement in javascript code?

    var this.numPages = NUMPAGES;
    for (var i = 0; i < numpages; i ++)

    Search.Query ("Signature of the employee", "ActiveDoc");
    Console.println ("Pages that do not include a signature of the employee:" + this.pageNum + "");

    Any help will be most appreciated.

    "The signature of the employee" are the 2 words and not one. The method that you use to get the word gets only a single word. You also want to identify the "not true" found for the situation of the page and not the "real" found on the page.

    var ckWords; pair of words to test
    var bFound = false; Logical state of the words found
    Browse through the pages
    for (var i = 0; i)< this.numpages;="" i++="" )="">
    bFound = false; all found false
    numWords = this.getPageNumWords (i); number of words on the page
    loop through the words on the page
    for (var j = 0; j)< numwords;="" j++)="">
    get the pair of words to test
    ckWords = this.getPageNthWord (i, j) + ' ' + this.getPageNthWord (i, j + 1); test words
    do a check to see if the pair of words is string "Signature of the employee.
    If (ckWord == 'Signature of the employee') {}
    bFound = true; indicate the logical value found
    Console.println ("Pages that includes a signature of the employee:" + (this.pageNum + 1) +' ' "");
    break; no need to test more to this page
    } / / end of Signature of the employee
    } / / end of Word loop
    a test to see if the words not found
    if(Bfound == false) {}
    Console.println ("Pages that do not include a signature of the employee:" + (this.pageNum + 1) +' ');
    } / / end not found on the page
    } / / end of page loop
