I want to know how to use a variable string to reference a movie clip in a hierarchy in AS2.
For example, and please forgive my newbie coding:
If my variable is defined as:
_root.MovieName = "Bob";
Then I'd like to be able to write:
_root.MovieName.ChildClip.gotoAndPlay("Label");
Where MovieName is the string "Bob" and not an actual instance called "MovieName". So Flash looks for an instance of "Bob" and goes into the child clips from there.
Is there any way to do this?
_root actually is a reference to the "root" of the movie, which also inherits a bunch of properties, it behaves like an object, so yes, you can do things like the following:
trace(_root["Bob"]); //Should return the instance.
var movieName = "Bob";
trace(_root[movieName]); //Should be the same.
I FOUND THE ANSWER!
In order to refer to movie clip instances using variables, first declare that variable as a string, then use the this[] handler. Here is the code that worked for me and the page that held it:
// CREATE THE STRING
var newString:String = "movieClipInstanceName";
// ASSUMING YOU ALREADY HAVE A MOVIECLIP WITH AN INSTANCE NAME OF "movieClipInstanceName" ON STAGE,
//CHANGE THE ALPHA OF THE MOVIECLIP TO 0
this[newString].alpha = 0;
And the page:

Big thanks to everyone who pitched in to help me!

I'm quite new to progamming. So here's my function to select a random image in my drawable folder.
fun generateimage(index:Int)
{var images=arrayOf(R.drawable.img1,....)
main_imageView.setImageResource(images[index])
This works as an image is shown randomly every time I start the application. But I would like to be able to know which image was selected. Preferably from retrieving the image name to string.
Possible duplicate of
How to get drawable name from imageView
However, a better implementation would be to have the value in a list of int and put your R.drawable items inside it. That was you can access which element is being shown.
You can do something like this:
fun main() {
val arrayImages = arrayOf("image1", "image2", "image3", "image4", "image5")
// in your case actual images.
val randomIndex = (0..arrayImages.size).random()
val randomImage = arrayImages[randomIndex]
println(randomImage) // in your case: main_imageView.setImageResource(randomImage)
}
Note that you need to assign the variable of randomImage so you can access it later on. I don't know what type "R.drawable.img1" is, but the object you set inside this array has to store the name of the file, so you can retrieve it that way.
I have just read a text file and extracted a string and stored it as a variable. This string also happens to be the name of a class I want to reference in order to use in a function for example. The "which_class" variable is the whichever class was stored in the file
I tried passing the which_class variable in as a parameter to the function. Removing the quotations seems to make it work but I am unsure how to do this.
class needed_for_func_one():
multiplier = 1.23
class needed_for_func_two():
multiplier = 1.15
def random_function(which_class):
print(123 * which_class.multiplier)
PSEUDO CODE
READ FROM FILE STORE STRING AS "which_class"
which_class = "needed_for_func_two"
random_function(which_class)
But this didn't work it just gave me an attribute error
the eval function could help you here.
random_function(eval(whichClass))
However, you should probably rethink whether you really want to it that way or if there is a much cleaner solution.
I think your question is related to this one
How you call the function depends if it is a global function or if it is inside an object.
globals()['call_this_function']() # this is probably what you need
or
getattr(from_this_object, 'call_this_function')()
first, to use a class you need an object of a class.
so if what you read is a name of the class or any other thing it does not matter, just use an if statement to decide what is inside that variable so-called "which_class".
then create an object like :
if which_class=="needed_for_func_one":
newObject = needed_for_func_one()
elseif which_class=="needed_for_func_two":
newObject = needed_for_func_two()
then use the print like :
print(123 * newObject.multiplier )
I followed How do you copy a datetime field from the current document to a new document and I try something like this:
Cdoc.save();
Pdoc.copyItem(Cdoc.getDocument().getFirstItem("mytest1"));
getComponent('exampleDialog').show()
But I get a handling error message.
Thanks for your time!
Assuming Cdoc and Pdoc are defined as xp:dominoDocument data sources then you have to change your code to:
Cdoc.save();
Pdoc.getDocument().copyItem(Cdoc.getDocument().getFirstItem("mytest1"));
getComponent('exampleDialog').show()
So, you only need to add .getDocument() to Pdoc to get the Notes Document. Otherwise it fails and you get the error "Error calling method 'copyItem(lotus.domino.local.Item)' on an object of type 'NotesXspDocument'".
Keep in mind that you have to save Pdoc after copying item too if you want to show the copied item in your exampleDialog.
If you don't want to save document Pdoc at this point yet then you can copy the item on NotesXspDocument level with just:
Pdoc.replaceItemValue("mytest1", Cdoc.getItemValueDateTime("mytest1"));
getComponent('exampleDialog').show()
I do not often use "copyItem". You are not specifying if you are using NotesDocuments or NotesXspDocuments, so I will write a quick thing about both because they should be handled differently.
var currentDoc:NotesDocument = ....
var newDoc:NotesDocument= ...
newDoc.replaceItemValue("fldname", currentDoc.getItemValueDateTimeArray("fldname").elementAt(0))
if currentDoc is a NotesXspDocument, use the following
var currentDoc:NotesXspDocument = ...
var newDoc:NotesDocument=...
newDoc.replaceItemValue("fldname", currentDoc.getItemValueDateTime("fldname"))
Otherwise, you could continue trying with copyItem, I just lack experience with it.
EDIT
Just some things to add, remember that putting calling xspDoc.getDocument(true) will update the background document and this might be needed. Also, in the comments for that article you posted, they mentioned the possible need to put that document into another variable.
var docSource:NotesDocument = xspDoc.getDocument(true);
var docNew:NotesDocument = ...
docNew.copyItem(docSource.getItem("blah");
Also remember that copyItem is a function of NotesDocument and not NotesXspDocument.
Scenario:
I have x number of classes. Lets say 10; Each class does different UI Functions. When a user loads a file, that extension tells the program the classname to load; but it's in the form of a string.
Is there anyway to pass a string off as a classname? Something to the effect of.
var classname = "Booger";
var nose = new classname(){ //classname really means "Booger"
//Do Operation
}
You can reflect a type by name using var t = Type.from_name(classname);, however, this works on all types, including enums and structs and it might be the type Type.INVALID. You should probably do some checks, like t.is_a(typeof(MyParentClass)).
You can then instantiate a copy using var obj = Object.new(t);. The whole thing would look like:
var classname = "Booger";
var t = Type.from_name(classname);
if (t.is_a(typeof(MyParentClass)))
return Object.new(t);
else
return null;
It's also worth noting that the run-time type names have the namespace prepended, so you might want to do "MyNs" + classname. You can check in either the generated C or doing typeof(MyClass).name().
I've had the same problem as the OP in regards to getting an assertion error against null. If you take a look at the Glib documentation (in C) it mentions you have to register your class by actually specifying the class name first before you can actually use a string representation of your class name.
In other words you have to use your class first BEFORE you can instantiate a copy of your class with Glib.Type.from_name ("ClassName").
You can use your class first by instantiating a class instance or by getting type information for your class.
var type = typeof (MyClass);
var type_from_string = Type.from_name ("MyClass");
Furthermore, when you use Object.new to create a class there are two things you need to be aware of:
1) You need to cast the return value to get your specific class or base class.
var instance_of_my_class = Object.new (type) as MyClass;
2) Constructors for your class will no longer be called (I don't why). You will need to use the GObject style constructor inside your class:
construct {
pizza = 5;
}
Each input field in the CKEditor dialogs are renamed with a unique number, but the number changes depending on what options are visible.
I need to reference 'txtUrl' which has an id something like #35_textInput.
So far I have discovered that something like this should work:
alert(CKEDITOR.instances.myElement.document.$.body.getId('txtUrl'));
But it doesn't. Please help.
#Rio, your solution was really close! This was the final solution:
var dialog = CKEDITOR.dialog.getCurrent();
dialog.setValueof('info','txtUrl',"http://google.com");
return false;
var dialog = this.getDialog();
var elem = dialog.getContentElement('info','txtUrl');
within an onchange part of an element I now use
dialog = this.getDialog();
alert(dialog.getContentElement('info', 'grootte').getInputElement().$.id);
and it gives 'cke_117_select' as a result. (It's a selectbox)
alert(dialog.getContentElement('info', 'txtUrl').getInputElement().$.id);
gives 'cke_107_textInput'.
I think this is what you (or other visitors to this page) are looking for.
SetValueOf still doesn't provide the id, which you may need if you want to do more than fill a text field with a certain text.
