Reference functions inside un untitled script object

Hello,
Does someone knows how to reference a function inside an untitled script object?
thank you

xfa.resolveNode("#script").functionName()
You should always name your scriptObjects ...it makes accessing them much easier.

How to reference JavaScript functions stored in a script object on a different page?

Hi,
I have a form which has 2 pages. I have a bunch of JavaScript functions under script objects on page 1. How can I access these functions from page 2?
I tried the following but none of it work:
form1.page2.#variables[0].testScript.doThisNow();
form1.page2.variables[0].testScript.doThisNow();
form1.page2.variables.testScript.doThisNow();
Please help.

Hi,
Simplest way would be to drag the script object to be under the root node (form1). On both pages would would then be able to reference the function by:
testScript.doThisNow();
If you leave the script object under page1, then from page2, the following should work:
page1.testScript.doThisNow();
Hope that helps,
Niall

How to call a function from a different script object?

Hi All,
Here is the scenario,
I have 2 script objects A and B .
In script object A i have a function called "funcA" and
in script object B i have a function called "funcB"
Now I want to call funcA from funcB which is not happening.
I tried doing
A.funcA();
inside funcB , but not able to access.
Kindly help.
Thanks
Abhiram

Hi Abhiram,
Just a guess - try including the root node/node reference above the script object.
form1.A.funcA();
What does the JavaScript Console say when firing the function? Are there any errors?
Your script objects can contain multiple functions. So you could move funcA() and funcB() into the same script object. This will make it easier.

How to create inline function inside a test script

i ahve a test script. i want to create a inline function that will do some stuff. how can i do it syntatically.
declare
-- Local variables here
i integer;
begin
-- Test statements here
-- have a function spec and body how?
end;

Hi,
You can define a function in the DECLARE section and use it in the BEGIN section, like this:
declare
-- Local variables here
i integer;
     -- Defining successor function
     FUNCTION successor (in_num IN NUMBER)
     RETURN      NUMBER
     IS
     BEGIN
          RETURN     in_num + 1;
     END     successor;
begin
     dbms_output.put_line ( successor (1) || ' = successor (1)');
end;

A question on script objects

I have placed a script object on my form to control the field color and it works fine in Adobe Reader X but not in previous versions of Reader and not in Acrobat pro 9.
Can anyone tell me what’s wrong?
The script object looks like this:
form1.#variables[0].RGA_format - (JavaScript, client)
function RGA_colorOld()
xfa.resolveNode("this.ui.#textEdit.border.fill.color").value = "220,220,220";
function RGA_color()
xfa.resolveNode("this.ui.#textEdit.border.fill.color").value = "255,255,255";
And is called from the fields on the docReady event and the Change event by this script:
form1.blanketB.Moder.EftNvnMor::docReady - (JavaScript, client)
RGA_format.RGA_colorOld(this);
form1.blanketB.Moder.EftNvnMor::change - (JavaScript, client)
RGA_format.RGA_color(this);
Regards,
Kirstine

Hi Kirstine,
When calling the function, you are passing through the object as a parameter. However the function in the script object does not have a corresponding parameter to receive this.
You can probably pass the object reference through as:
RGA_format.RGA_color(this);
However I prefer to declare a variable first and pass this through:
var fieldObj = this.somExpression; // declare a variable to be passed into the function
colourControls.fieldGetsFocus(fieldObj); // calls the function "fieldGetsFocus" in the script object "colourControls"
Notice in the example, I when declaring the function, I have a parameter "fieldObj", to receive the information that is being passed through.
function fieldGetsFocus(fieldObj) // first function
A small point about the function in the script object. I know the function is a single line, but I would prefer to see this wrapped in curly brackets.
Lastly changing the fill requires access to the ui properties. These are different for each object type. For example the script you have is for a textfield. This would not work on a numericfield.
I do have an example here of a function that does what you are looking for: https://acrobat.com/#d=XGj9UEk4lSbDSoArnQU8dQ. Note how I check what the object is and then resolve the correct ui property. This makes the function must more reusable.
Hope that helps,

Functions in script objects not being recognized after certain point

Hi all,
I'm wondering if anyone has figured out why after normally about 300-500 lines of JavaScript in a Script Object, sometimes the functions near the end are no longer recognized by the XFA processor when referenced ("TypeError: Scripts.myFunction is not a function").
When reordered, further up the script object, they work as intended. The line at which it no longer recognizes functions also isn't always the same and I have worked with some script objects that have over 800 lines with all the functions still working.
I've tested in Designer 9 and 10, Reader 8 9 and 10.
Please at least let me know I'm not the only one. I knew of one other developer that had come across the same issue.
Kyle

Thanks radzmar!
JSLint didn't find anything but it set me on the path towards looking for syntax errors. I deleted code in the script object line by line until I narrowed it down.
Turns out it is Regular Expression literals, in particular trying to escape (\) the metacharacters ($.{}[] etc).
For example, var reg = /\}/; should technically match any right-handed curly brace, which in fact it does! The function that it is in works perfectly but every function written below it is not recognized by the XFA processor. Just out of curiousity I tried reg = /\{\}/; which matches {} and all the functions below now are recognized. It seams as though, even though using the escape character is allowed in core JavaScript, the processor sees it as a syntax error because it's not terminated.
Anyways, the easy fix is of course using the RegExp constructor var reg = new RegExp("\\}"); but I'll miss the confidence I had using Regular Expression literals.
Thanks again for the nudge in the right direction.

Insert Script Object?

In Acrobat Pro you can create a document script as follows:
function Hello()
app.alert("Hello World")
And call this Hello.
If you create button on the page then create an action on Mouse Up Run a JavaScript which looks like this:
Hello();
A message box appears saying Hello World click OK and press the button and it keeps coming back.
Now in Designer this is a little different.
I create a new page, insert a script object rename it to Hello and type:
function Hello()
app.alert("Hello World")
I then create a button and on the mouse up action type;
Hello();
If I try this I get the following mesaage:
TypeError: Hello is not a function
1:XFA:form1[0]:#subform[0]:Button1[0]:mouseUp
Why is it so?
Even removing the script object and going to the Form properties Variables tab and entering the function script there does not seem to work.

Thanks Steve,
It works without a hitch. Im still getting my head around JavaScript and 2 weeks, 6 hours a day of reading and testing and reading is slowly getting clearer I think.
Just to make sure Im getting this clear in my head. The way I had the script before was when it was applied to the field that showed the value it was referring to this as the field itself. So it worked not worries because it was point to the itself.
When I tried to apply the same script in a script object field (variables) that the whole documents can reference it was only in as a variable. The line form1.variables.setTotals.Totals(); did not do anything because it did not see the totals as a function and refer to it, and as a result nothing would appear in the filed. By adding obj to the script it tells the form that its an object and the objects formula is spei1 + spei2. This now means that the script can be applied to any filed and that is where form1.variables.setTotals.Totals(this); comes in. It tells the filed apply the object (Totals [spei1 + spei2] ) to this filed.
Does this mean that any script placed in the Variables field needs to be referred to as objects?
The reason I was taking this approach was to resolve a problem posted earlier.
I thought by having the script as a script object that was applied to the document rather than the field it would update the other fields that refer to it. Which I now realize will not happen. Could you suggest a conditional statement that I could put in to:
If special item 1 = $12.00 the result in the total = $12.00. If I then click on one of the fields in the special column say in Monday for example the result should be $12.00. If I then decide to enter another $12.00 in special item 2 the total will now be $24.00 but the Monday result will still say $12.00.
Is there a way to have it check that it the figure which may appear in the Special column, to update that result as well?
Should I be look at a message box instead telling the user there is a difference and for them to re-click on the Monday field to update it?
Any suggestions would be appreciated.
Regards, John.

Script Object when rendering to HTML

Hi,
I am developing a form that requires the same script to be reused many times. This form is going to be rendered out to HTML through Workflow, and I'm not sure how to access a script object when rendering to HTML. The root of my form is MISForm so I tried this:
MISForm.variables.getXML.getXMLDoc("http://lcwftest:8080/services/getEmployeeInfo?method=s ynchronousInvoke&empnum="+this.rawValue);
getXML being the script object and getXMLDoc being the function. But this returns MisForm is not defined.
I also tried a reference straight to the object
getXML.getXMLDoc("http://lcwftest:8080/services/getEmployeeInfo?method=synchronousInvoke&e mpnum="+this.rawValue);
but that also returned "is not defined"
How do I reference the script object.

I believe it gets something like
xfa.resolveNode("MISForm").getXML.getXMLDoc...
It also depends on if your script object is located in the root or if it is located within your page if you understand what I am trying to say. With pdf you can have a global script and reference it on each page but with html I would be more than happy if you find a solution on it... you have to have the script object on each page.

Problem creating simple Script Object

I have not been able to get this simple Script Object to work. It should be simple, but this is my first script object, and as I'm new to LS and JS I'm not very adept at writing JS (functions, variables, you name it).
Would someone be so kind as to help me get this easy one down so I can study it and see where I went wrong?
What this script object would do is call a function that checks the value of two check boxes. If one checkbox's value = 1 then the textstring "Male" gets written to the lower text box. If the other box's value = 1, then "Female" is written to the same box (and of course, Male is deleted)
Thanks!
Graham

Hi Graham,
Adobe Reader using the same JavaScript engine as used by Mozilla (called SpiderMonkey) and their website has a lot of information about learning and using JavaScript, https://developer.mozilla.org/en/JavaScript. Only problem is Mozilla has moved on to version 1.8.1 and I think Reader is still on 1.5, but they make it easy to work out what features are available in what version.
Array literals are good if you aren't going to reuse them, maybe a better alternative would be to reference the captions of the checkboxes or radiobuttons.
Bruce
Writing ["", "MaLe", "FemaLe"] creates an array literal so I could have written something like;
var
genders = new Array("", "MaLe", "FemaLe");
var gender = Number(Gender.rawValue);this.rawValue
= genders[gender];

How to open labview program with Quit Labview function inside?

Hi Any idea how to open labview program with Quit Labview function inside?
I forgot to add and set the condition of the type for this program.
If the program is an application, it would close straight away.
If it is still labview work, it will go straight to editing program without closing.
So I need to recover, open it and make some changes.
Clement
Solved!
Go to Solution.

Put the VI in a project and open it from there, then it shouldn't autorun. You can use App.kind property of application to decide whether to close or not.

Using a script object

Hi,
I have beginner skills using LC Designer ES and am trying to insert and use a script object. I found a JavaScript function online: http://home.online.no/~pjacklam/notes/invnorm/impl/misra/normsinv.html and am trying to get it to do some math calculations in a Designer form.
I've uploaded a sample test form at: http://elearningprojects.com/TestFormula1.pdf
Can't get it to work.Trying to run the JS formula in the script object (by clicking on a button), using a few hard-coded variables, and display the results (Dprime1 and Dprime2) in 2 text fields.
I would much appreciate if someone can take a look and suggest how to get it working correctly.
Thanks for your help.
Kind Regards,
saratogacoach

Hi Paul,
Thank you for your reply and suggestions. With beginner skills in LC Designer (I'm a retired social worker), I am not sure how to do this.
Is my identifying the script object path correct?
form1.#subform[0].#variables[0].SO1.function_name(NORMSINV(p));
When you say "You are calling this function a few times in your code so you will have to modify each call." I am not sure how to change this.
I currently have (note that I added the SO1. to the function calls):
var p = totalscore5
var probit1 = SO1.NORMSINV(p)
var p = totalscore6
var probit2 = SO1.NORMSINV(p)
var Dprime1 = probit1-probit2
var p = totalscore8
var probit3 = SO1.NORMSINV(p)
var p = totalscore7
var probit4 = SO1.NORMSINV(p)
var Dprime2 = probit3-probit4
Can you specify what a modified script would look like? I'm stuck.
Also, have I set up displaying the Dprime1 variable's value in the TextField1 correctly?
Thanks very much for your help.

Acrobat standard 9.0 error while enabling commets option using Java script object

I'm using the below java script code in my VB 6.0 application for enabling commets options in the PDF file
Dim oJSO As Object
Set oJSO = mPDDoc.GetJSObject
oJSO.Collab.showAnnotToolsWhenNoCollab = True
It is working fine till Acrobat 8.0. Now I'm trying with Acrobat 9.0 standard edition, it is throwing scripting error 'An unhandled Win32 exception occured in Acrobat.exe[308].
Can anyone suggest the way to enable 'comment' options in Acrobat Standard 9.0 using Java Script Object?
Thanks

I get much the same problem with VB6, Acrobat 9 Pro and WinXP SP3. When I single step the line:
oJSO.Collab.showAnnotToolsWhenNoCollab = True
in debug I go to the error handler for my Sub. Inspecting the VB Err object has Number = -2147417851 and Description = "Automation error
The server threw an exception." I get a Microsoft crash notice about Acrobat a short while later.
I've experimented with the JavaScript debugger in Acrobat and you can execute Collab.showAnnotToolsWhenNoCollab = True and reference the value of Collab.showAnnotToolsWhenNoCollab in the console. The problem appears only when accessing Acrobat Javascript through the Interapplication Communication API.
If anyone can help it would be appreciated. I tried Adobe's Acrobat support and they were no help at all.

How to use select a vi function inside a loop?

I am modifying the notifier basics part 2.vi to send a notifier to each of 64 sub-vi's. How can you use the 'select a vi' function inside a loop for 64 iterations to access the individual filenames??
Attachments:
Notifier_BASICS_Part_2.vi ‏87 KB

If all you are trying to do is send notifiers to each of these 64 subVIs, I would suggest not doing it in a loop, but rather just placing the 64 subVIs in your diagram.
The alternative is of course to use the call by reference node and have an array of VI names. This is a little cleaner on the diagram, but 1) doesn't occur in parallel and 2) is a bit tricky. Additionally, you have to be sure that your array of filenames is correct, and that you NEVER move or rename those VIs. Of course, you could always put them in a directory and create an array by reading the directory contents.
Either way, good luck, it doesn't sound like fun.

How to call a function inside a class?

Hello, i am trying to fire a function onPress .. this
function is inside a class.
In this function i refer to another function inside the calss
to call a Tween. It never arrives in the second function.
I tried to make an example.
In the fla file i have:
var test:makeMovie = new makeMovie(this);
You will see a red squere and you can press on it. It should
run the tween class. Am i using the delegate class wrong?

I always have to use test movie and trace a couple of times
each time I start to use Delegate.
It wraps function.apply I think, which I tend to use more
often.
try using:
Container.onPress = Delegate.create(this,setAlpha);
and then just
setTween()
inside your setAlpha....
That's conceptually how I think I would try it above if I was
doing something similar.
I'm not sure it would have the desired effect even if the
delegate was executed as you have it coded. Unless you want
setTween's execution scope to be the Container clip in which case
you might need to do what kglad said and change the Container
reference to 'this'.
The way you have it at the moment inside setAlpha the
Delegate.create is simply creating a function...and not excuting
it.
its like : function something(){trace('what')}
and not like : something();
Below is some quick code that helps show how things work.
Notice that I assigned the delegate function to mainFunc....so that
along with the last example might provide a clue. Just paste it on
a frame and take a look at what's happening.
