Flash :: Accessing Last Element Of Array Dynamically?

(CS3) Accessing An Array Dynamically
Hi, Thanks ahead for any help. I'm learning so please put up with my stupid questions.

Basically I've got a load of Arrays, and i do a function called LoadImageArray, passing in the array, and it's name as a string. a function will run, and inside there i want to update the array. I don't know what the array name will be, so how do i change the array using the "thisName" argument? (which has the array name inside)
Just saying thisName[i] etc... is referencing the argument (I think they're called arguments?) and I don't know how to make it reference the Array of the same name.

Code:
var imageArray0:Array = [];

LoadImageArray(imageArray0, "imageArray0")

Code:
function LoadImageArray(thisArray:Array, thisName:String) :void {

//Unimportant Stuff Cut Out
//Below function will run...

function onAllLoaded(done:Event) :void {

//Unimportant Stuff Cut Out
//Here I want to access the Array (for this example it is imageArray0) that has been passed in under the argument "thisName".

}
}
}

Thanks for any help

Dynamically Accessing Array Variables
Here's my problem:

I am loading the variables for a page into an array. A couple of timelines into my movie I have a handy function to access one of those variables based on what number I feed the parameter of the function:

function image_display (i) {
caption = eval ("../../:page [../../:page_current].image_"+i+"_caption");
}

The idea is that I send this function "1" as a parameter and it will give me the value for "page [page_current].image_1_caption", which is on the root timeline (I like relative as opposed to absolute references, but it shouldn't make a difference either way).

The problem is that I cannot get this to come up with anything but "undefined". If I hardcode this without the "eval" statement and replacing the "i" with "1" it works fine, which says to me that I need to construct the variable I want to get differently, but I don't know how to do that.

Any thoughts?

Dynamically Accessing An Object Array
I am just full of quesitons today.

How can i access an object array's length
if...

data.area01=name1;
data.area02=name2;
data.area03=name3;
data.area04=name4;

just for clarification the array goes deeper...

data.area01.urllink="www.etc.com";
data.area01.urllink2="www.blog.com";
data.area01.publication01="blahblah";

------------------------------
I just want to find the length of data
but if i do ntotal=data.length i get undefined.

It sure would've been a lot easier if the areas weren't labelled with numbers appended to their ends. Then I can use a for...in loop

Array Text Into Textfield And Creating New Line For Each Array Element
I have an array called dropTarg1 which stores dropped-in items.

I want to loop through this array and in a textfield, display each array item on a new line of this text field

I think I need to use something like Array.join("/n") but I can't get it working properly. I hope that the /n would create a new line of the text field called reviewBoxContentText.

for(var i:Number = 0; i<dropTarg.length; i++){
with(reviewBoxContent.reviewBoxContentText){
autoSize = true;
text = dropTarg1.join("/n");
}
}

All that is happening though is that the text field displays on a single line with /n in between each array element.

[F8] Finding A Dynamically Created Element
If I dynamically create an element, and after its created add a listener to it, how would I grab that element?

For instance, say I create a button
var btn = new Button();
btn.text = "Click Me";
parent_element.addChild(btn);

Now that I've created an placed it, I want to add a listener, do I just do
btn.addEventListener, or do I need to alias it first?

Can't Add Dynamic Text Element Dynamically
I have a bunch of images loaded into my movie from external URLs. They sit nicely next to each other.

Now I'm trying to overlay some custom text on each one, but I can't get it to show up.

I created a movie clip in my library and placed a dynamic text field at the center. I named this dynamic text field, "captionField" and centered it and exported the symbol for actionscript as "captionHolder"

Once my clips are done loading, I use attachMovie("captionHolder", "newCaption1", ....) to overlay the caption field. Then I set the value of newCaption1 to "Hello World" but it doesn't show up.

Even if I set the default value of the dynamic text field (I manually type in the value to start inside Flash) it doesn't show up. But if I change the type of the text field to "Static Text," then the default shows up perfectly on top of the image.

I've also tried createTextField but couldn't get anything to show up. Any ideas?

Dynamically Change The Height Of An Element
Hi there,

I have an animated graph in flash and I would like to set the values (heights of the bars) using data imported via an XML file.

I can successfully import the data, but I have no idea how I change the height of the bars!

Can anyone point me in the right direction?

Thanks in advance!

ARRAY Element Value - Not Array Index Value
Hi all -
Have a small problem converting the below variables from PHP into a useful Ascript Array. I keep getting the value of the array index, rather than the value of the variable in question.

So I know I have 3 rows in my database (totalRows var),
and I have a incremental values for the "recordId"'s (which correspond to the record ID in the db).

totalRows = 3

recordId0 = 1
recordId1 = 5
recordId2 = 6

this is the code I am using:

Code:
function extractMenu() {
//returned vars (FYI): totalRows=3&recordId2=6&recordId1=5&recordId0=1&result=okay&
this.menuArray = new Array();
with (menuLoad) { //menuLoad is the LoadVars object holding PHP vars.
for (i=0; i<=totalRows-1; i++) {
menuArray[i] = recordId + i;
trace(menuArray[i]);
//the trace returns:
//0
//1
//2
//I was expecting the values:
//1
//5
//6
}
}

any takers?

Test If Array's Element Is An Array.
I'm recursively looking through an Array, and I'm looking for a solid way to test if an element is actually an Array(there is a chance that the tested array element is another datatype). I was thinking that I could use the length property to test, however looking in the index of ASDG2 I see that there are a few other Objects that possess the a length property, and I am afraid that this might cause a problem.

look at
nav_array[i].length >= 1
below

Is there a way to use typeof on an Array, and have it return anything other than Object?

Code:
private function recurseThroughArray(nav_array, itemsArray, depthHolder){
for(var i=0;i<nav_array.length;i++){
depthHolder.push(i);
if(nav_array[i] == itemsArray){
var returnDepth:Array = depthHolder;
break;
}else{
if(nav_array[i].length >= 1){ //make sure that this is an Array
recurseThroughArray(nav_array[i], itemsArray, depthHolder);
}else{
depthHolder.splice(depthHolder.length-1,1);
}
}
}
return returnDepth;
}
also, I'm new to recursion, and I haven't tested this yet.

Element In Array
Can anybody tell me if there is a built in array function in Actionscript which returns true if a value is an element of the array, and false otherwise, or do I have to write my own by comparing each element?
Thanks

Set Vars To Array Element
I need to on the first frame:

Comma In An Array Element?
Hi,

I am using LoadVars to bring in array items, delimited by commas. Unfortunately it is required that some array elements include the character "," but not as a delimiter [example: "I need to add commas like this, thanks."]. We tried using the %2C escape sequence but this does not work in IE [no idea why, but it instead adds a line break], is there any other way to display a comma in an array like this? Thanks a lot for any help,

Get Random Element From Array
apologies for this easy question but I'm new to actionscript and flash!

I have an array with a list of things, and I simply want to pick out a random element from the array. How can I do this?

I was trying to solve this by having a random number, multiply by 10, then have a function to call to check whether it is greater than the count of the elements in the array, but this seems long-winded and it didn't work anyway!!!!

Thanks.

Array Element Names
Hello gurus

Stuck on what seems a simplish question and cannot find the info anywhere.
I want to call an array element by name and clear it totally from the array.

I know that if you use delete on an array, it only clears the value.
I read somewhere that if you name the elements, you can then use delete to clear the value and its container.

q1/ Does naming the elements make it an associative array?

q2/ If this is so, and I cannot use the length method, is there some other way of getting the length?

q3/ Any better ways of doing this that the way I am going about it.

Have looked at Objects and deleting but again, cant get length.

Thanks if you can help out. I am just diving in to actionscript and haven't had that AHA! moment yet.

[Help] Deleting An Array Element
Ok I created a function to delete an element of an array which looks like:

Code:
function deleteD(index,array){
newArray =[];
if (index == 0){
}
else{
newArray = array.slice(0,index);
}
if(index >= array.length-1){
}
else{
newArray.push(array.slice(index+1,array.length));
}
return (newArray);
}

But for some reason it doesn't work properly. For example:

Code:
testArray = [['a',0],['c',1],['e',2],['g',3],['i',4]]; //an array with some random elements.

testArray = deleteD(1,testArray);//Should delete element 1: ['c',1]
trace(testArray) // traces a,0,e,2,g,3,i,4 like it should
trace(testArray.length) //traces 2, when the length should be 4
trace(testArray[1]) // traces the second element which should be ['e',2] as e,2,g,3,i,4

I attached the .fla so you could see it, and any help would be great. I've been pulling my hair out over this...

Delete An Element On Array?
Hello,

direct to the point. my problem is, i have an array and want to delete an element, lets say "my_Array[4]" from it. the thing is i can erase the variables, but that leaves an empty space en "my_Array".

how can i move all the records of "my_Array" to fill the blank space?

after i delete the element i got this (and i dont need it that way):

my_Array = [dog, cat, plane, train, undefined, house]; (this is a geek example).

please help.

Array Element Visibility
Describes the mood or content of the topic posted 03-19-06 09:27 PM
Hi, I have a script problem in Flash not sure it can be easily solved.
I am a casual Flash user and not sure if there is a easy solution to this:

I have and array of elements from which one of them is retrieve randomly, and then stored in the variable selectedElement

myElements = new Array("beerBelt", "bottleBelt", "canBelt", "chipBelt");

function randomAll() {
_global.randomNumber = Math.round(Math.random()*(myElements.length-1));
_global.selectedElement = myElements[randomNumber];
};

Inside a MC in the same scene I have a series of MCs with the instance name exactly the same names as the variable elements, they are invisible from the first frame,

beerBelt._visible = false;
bottleBelt._visible = false;
canBelt._visible = false;
chipBelt._visible = false;

then an action frame appears to make the selected MC visible,

selectedElement._visible = true;
selectedElement.gotoAndPlay(_currentframe + 1);
stop();

for any reason (my lack of knowledge sure is the one to blame) I cannot make that element visible, I tried everything I know.
Could you please advice me what is the best way to aproach this problem?
Is it really possible to use variables values (in this case strings) to modify a element property?
Am I missing something?

Please any comment would be really welcome....

Save Array Element
Is it possible to save an element of the array to a txt file? or do I have to create a new array to hold that value then save it? Please note that I only have one variable that when the mouse is over the movie clips it will show the element of array on to that variable.

Array Element Not Being Defined
Hey

It's late here and i'm tired, so it could just be that, but i can't work out why this isn't working:

ActionScript Code:
trace ("index" + index)
_root.SavedSO.data.Inventory[index][0] = getable[i];
_root.SavedSO.data.Inventory[index][1] = _root.SavedSO.data["room"+x+","+y+","+z].getinfo.split("*")[i];
trace(_root.SavedSO.data.Inventory[0][0])

index is 0, as it should be, yet the trace at the end returns undefined. However, if i remove one of the array elements it works... Does anyone know why this would be, or how to fix it?

Swapping Element In An Array
Hi all,

Can someone tell em what I'm doing wrong here? I basically want to swap the order of two elements in the array. The splice command works fine with only a single field in the array eg bob.push("aaa") but I get undefined when using multiple elements in the Array...help!?

bob = new Array()
bob.push({name:"aaa",age:1})
bob.push({name:"bbb",age:2})
bob.push({name:"ccc",age:3})
bob.push({name:"ddd",age:4})
bob.push({name:"eee",age:5})

bob.splice(1,0,bob.splice(2,1))

trace(bob[0].name) // gives aaa
trace(bob[1].name) // gives undefined
trace(bob[2].name) // gives bbb
trace(bob[3].name) // gives ddd
trace(bob[4].name) // gives eee

Array And Deleted Element
Hi,
I have a Form with 6 input Text fields.
Now the Submit button should find out, if all Text fields are defined.

The Array is updated on enter text with >splice< like

var a:Number = 0;//
while(a<6){
this["formTF"+a].onChanged = function(txt){
var theText = txt.text;
var theNo:Number = this.avar;
theSubmit_array.splice(theNo,1,theText);
};
a++;
}

All works fine, I have an array like this > AA,BB,CC,DD,EE,FF <

But, when the TF is left empty or previous entered Text is deleted, lets say TF no.2, then
my Array looks like >> AA,,CC,DD,EE,FF < soâ€¦ BB is gone and I have an empty space.

How can the Submit button read, that the TF no 2 is empty???
I have tried so many things during 2 days, but found no solution.
For ex. looping through the array like:

for(var x:Number=0,x<theSubmit_array.length;x++)
var checkStr = theSubmit_array[x];
if(checkStr == ""){
//play error
}
}
// but does not work.

Can anyone help me please??
Thanks.

Remove Element From Array ?

i want to remove the element "3" when i press button.

Remove Element From Array
Hello kirupers,

i am trying to remove elements form an array.
the array is kind of special: content depends on what you have clicked or not:

see some code:

pArr = [];
for(var i =0;i<max;i++){
johndoe[i].pressed = false;
johndoe[i].onPress = function(){
this.pressed = !this.pressed;
if(this.pressed){
pArr.push(this.obj)
}else{
pArr.remove(this.obj);
}
}
}

of course the remove function is my pb, not done yet.

i have tested some proto on it, but cannot figure it properly.

How can i remove the same object from the array, knowing that the array can contain several times the same object, so i do not want to delete it many times but just the good one ? so the trick is to remove only the object associated with the johndoe button.

maybe the pb comes from the way i push the elements ?

thx for your reading so far, hope this is an understanding problem.

Addressing Variable Value To Array Element
I am trying to assign the values of variables read from an external variable file to an array.

One way or another I really need to figure out how to do this-

I have been trying a routine similar to the following, however I can't get the array element to accept the expression as a value.

varArray = new Array();
LoadVariablesNum("vars.txt", 0);
// lets say that the txt stores the var "X"
set( varArray[0], X );

what is incorrect about this assignment?
