Flash :: Prevent An Item From Being Added To An Array If It Already Exists In The Array
Jun 22, 2011
I know how to remove duplicates from an array, but what I'm trying to do is prevent an item from ever being added to an array in the first place if it already exists. I'm pulling in data from an xml feed in a loop, and I thought that searching for that values index would work, but no matter what, the index is always -1. Here's my code:
[Code]...
Maybe I'm misunderstanding the indexOf function, but I thought it was supposed to return -1 if a value did not exist in an array. What am I doing wrong?

I have some script which grabs stuff from an xml file. The stuff grabbed from the xml is in a loop to create an automatic menu. This is all fine and dandy. Say there are 9 items in the xml file, I get 9 menu items with their unique id's.What I want to do is define an array for comparison against the info taken from the xml file. Say in the xml file I have nodes set up for Apple, Pear, Banana and Orange. With my current script I would get a menu with these items on it. What I need to do is be able to specify the items I want to appear on the menu. For this example I would want Apple and Banana only.
I have experimented with if statements, and it takes too much code to accomplish what I want I am sure there is a more compact way. My idea is to set an array with the items I want in it,then when the information is taken from the xml file,I need the script to do the function of creating menu items only with the items I have specified in the array. Below I have added the code, which has been modified from Kirupa's own squirrel finder tutorial.I need the code to be as reusable as possible, ie only the array would need to change.In my code the variable featureType would contain the information I need to compare against.
Code:
//set limits on the features that need to display
// define array
var featureLimits:Array = ["Apple", "Banana"];[code].....

I have two two-dimensional arrays, and this line of code:
openListParents[compWith] = openList[olID];
Does it work? Yes. However, openListParents[compWith] becomes openList[olID], but I want openListParents[compWith] to be the value of openList[olID]. This is what I get when I press CTRL+ALT+V:
[Code].....
This is because openList might change, and I want the value of that openListParents in the array to be the value of the openList at the time when the code is run.

Well, I looked at the example, and looks like that was still not what I wanted. Interestingly, I took the middle for loop out and now it appears I am not having issues anymore.[code]

In a nutshell, I have a for loop updating a dynamic text element but it seems to iterate so fast that only the last item in the loop is updating the text. I'd like the dynamic text element to be updated with EACH item in the loop, not just the last.I have a single frame movie where I create a simple array of strings from an external text file:
_global.i = 0;
_global.numplaces = 0;
_global.PlacesArray = new Array();
[code]....
The traces work fine and show that the for loop is iterating properly. However the place.htmlText dynamic text in a movie nested one level down (for tweening purposes) that I'd like the loop to update is only updating with the last item in the array.

Sorry if this is a little n00b-ish. I'm working in AS3. I've got an array of 8 buttons. I'm currently hiding the button that is clicked using e.currentTarget. How can I tell flash to make all the buttons that aren't the currentTarget to become visible (i.e. if a button has been hidden by previously being clicked, how do I tell it to become visible again when another button is clicked?)

I have what I think should be a very simple problem. I have an array and can access an element of it like this:
var test = finalArray[0];
Will be a number between 1 and 7
say this will trace a number.No there is a movieclip on the root of stage whose name is a letter (always the same, say "R") and whatever the number is. I'm trying to get this movieclip to gotoAndStop at the frame corresponding to the number that is test. However this isn't working:
"R"+[test as MovieClip.gotoAndStop(test)];

I'm using a multi-dimensional array (openImage[]) to track the open images in my multi-dimensional array (Images[]).
I would like to check and see if an element in a multi-dimensional array exists before I access it because there are rare occurrences where the data in openImage[] is not valid. I keep on getting errors every way I've tried it.[code]...

I'm using the following array to add children to the stage:
for(var i=0;i<6;i++) {
var aCherry=new cCherry()
aCherry.y=10
aCherry.x=10+100*i
stage.addChild(aCherry)
}
Now I want to modify each cherry based on another array. Something like this:
[Code]...
Clearly stage.getChildByName("aCherry")[i] isn't correct, but coming from JavaScript this makes the most sense to me and should accurately portray what I'm trying to achieve for you guys reading this. So, how would I actually do this? This being getting an array of children added to the stage under a certain name or class (so an array of cCherry would work too, if necessary), then using them in a way similar to the above loop.

I want to add a movieclip from the library and add text from an array into. After a few seconds, that will begin to animate off and a seconds instance of the movieclip will be added to the stage. In order to allow for some overlapping of the animation, i figured that I would just add [i] to the end of the instance and be able to control it that way. So far I'm not having any luck. In fact, right now I'm just trying to have it set the x position and can't even get that.
Code: Select allvar footerWords:Array = new Array("wordOne", "wordTwo", "wordThree" , "wordThree")
var i:int = 0;
trace(footerWords[i])

is there a way to check an array to see if an element has already been added? I'm working with an XML document where there are 4 possible variables, but these 4 vars are repeated several times over. It's reading in fine... I just want to pull those specific variables out of the XML and add them to an array, but I do not want them to duplicate. To say it another way... I don't want my array to be more than 4 items long (it is possible to be less) with a max of those 4 different vars.

Code:mcRotation = [000, 001, 002, 003, 004, 005, 006, 007];works just fine as is (well, it generates no errors). But as soon as I add one more element to it, 008, it generates an error:**Error** Symbol=alphabet bar graphics, layer=actions, frame=1:Line 8: ']' or ',' expectedI might as well forget about inputing the rest (up to 025). Just to verify, here it is up to 008 as I'm typing it:
Code:
mcRotation = [000, 001, 002, 003, 004, 005, 006, 007, 008];

I have an object which needs to be added to an array, but when it is, it doesn't show the string inside. However, when I alert the exact same object, I get the result I'm looking for.
Here's my code.
newArray.push(obj.responseData.results[i].phoneNumbers[0].number);
alertMe(obj.responseData.results[i].phoneNumbers[0].number);
The first line shows nothing in that location in the array, and the second pops up a phone number, just like I'm after.

I want to know if there is a method or some code to add new items to an array, but it want the items have the name of the buttons's instance name, or the label's name, so when i push the button, it adds its name to an array. Here is my code:
ActionScript Code:
tauri.addEventListener(MouseEvent.CLICK, addAddress);
abydos.addEventListener(MouseEvent.CLICK, addAddress);
tollana.addEventListener(MouseEvent.CLICK, addAddress);
dialNow.addEventListener(MouseEvent.CLICK, dialTo);
var tauriAddress:Array = ["tauri","abydos"];
var newAddress:Array = new Array();
function addAddress(event:MouseEvent):void {
newAddress.push();
I don't know if I should use the push method here, tell me what to put here for adding the instance name of the button to the array
trace(newAddress);
}

I'm trying to add an item to an array, but when I do, it keeps the results (prizeField) from before and adds the new ones to it. i.e. at the beginning if I push a string to the array I have 4 items. If I push another, I then have 9. Then 15 and so forth. Here is my code:
Code:
var myFlexParent:Object;
var prizeArray:Array = ["apples", "bananas", "cranberries"];
var textFormat:TextFormat = new TextFormat("Cairo", 48);[code].....
I know that I need some sort of removeChild() in there, but I cannot get it to actually work.

I am trying to avoid this error:TypeError: Error #1010: A term is undefined and has no properties.It is being caused when I reference an object that does not exist. My code automically goes through an array of objects and will sometimes try to reference a location that does not exist (like [-1][6] for example).I am trying to set a variable based on another variable from an object in that array like so:ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;If it does not exist, my program stops and I am thrown that error. My question is, how can I check to see if that object's variable in the array even exists before assigning the variable?
I've tried this, but it did not work:
if(Map.baseTileArr[ob.upY][ob.leftX]){
ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;

When the combo box is changed it will add items to another combo box, i.e if africa is chosen, all the countries in africa will be listed in the second combo box.
At the moment i am manually adding in all the countries, _root.combo1.addItem("Label", "Data");
for 60 countries that would be messy code, is there a way to do it in an array cause my advanced actionsript isnt that good. But i will need to be able to get the data of a country out later ....

I have a tricky problem in that I have an array that has been populated with strings ("item1", "item2", etc). However, at a certain point I need to pull one randomly out of the group, via a random number function. The issue is I cannot reference the items in the array by a number, I get an error. So when I try to get myArray(5) it doesn't work.
How can I work around this so I can grab a random item in my string array?
