Actionscript 3 :: Implement String 'in' Array?
Aug 7, 2011
suppose you have an array with a number of strings in ActionScript3 and you want to test if a test string is "in" that array. "in" only works against the index with Arrays in AS3 (which is totally retardo if you ask me), though it does work with ojects, but we're not talking about objects.improve (reduce) on this code I'm using now? I'm hoping to avoid defining a utility function - I'd like a nice elegant one-liner.
myArray.filter(function(item:*, i:int, a:Array) { return (item == testString); }).length
Since 0 == false we can use it in a test. Do note that testString's scope is defined in the containing function, encapsulated by the closure.
if (allowedProfiles.filter(function(item:*, i:int, a:Array) { return (item == name); }).length){ // yay! }

The data i want in the array is 'data.location' (the code i am having issues with is in the itemrenderer towards the bottom of the code snippet)[code]...

I have 5 different arrays for a bunch of excercises, like so:
const oef1:Array = ["citroen","schoen","boek"];
const oef2:Array = ["huis","muis","jas"];
const oef3:Array = ["boek","koek","sok"];
const oef4:Array = ["ei","bij","bot"];
const oef5:Array = ["vier","mier","muur"];
Now I want to set the current game. I do this by copying the array, like so:
var curArr:Array;
var curExc:int = 1;
curArr = ("oef" + curExc) as Array;
I can't convince flash to accept the string ("oef"+curExc) as an Array. How do I do this?
I have searched Stack Overflow extensively but I think I simply don't know the correct lingo for what I'm looking for. It's the only possible reason I can think of why I can't find the answer here because I'm sure someone must have already tried this.

I currently have an array that looks like this:
ActionScript Code:
var array:Array=new Array["p", "e", "t"];
What I want to do is use an if statement to make it something like this:
ActionScript Code:
if (array.something=="pet") {
Notice the 'something' after array. I'm not sure if there is a way to take the data from an array and compare it to a string.

I have a response coming in from a server that contains a ton of strings that I need to eval to have them replace arrays already set as globals. So program fetches response, evals string into an array, and then we do stuff with the array. I've played around with little tests and can't get it working.
ActionScript Code:
var superArray= new Array('3','4');
var testArray="superArray=['1','2']";
function testEval() {
eval(testArray);
trace(superArray);

Something like:

myArray = myString;
And then myArray ends up like:

Im trying to add the content of a loaded textfile into an array, that's why.

If I have an Array such as this:
Code:
var myArray = new Array("home.swf","contact.swf","search.swf");
And I use this
Code:
var myString = myArray[0];
How can I cut off the last 4 characters of that string - ".swf" - (I think this can be done if I start with a negative -1 )So I end up with
Code:
var myString = "home";
instead of
Code:
var myString = "home.swf";

When importing a variable from an external .txt file, I know that it will not properly import an array. I rember seeing a way to convert the string to an array, but I can't find it. Does anyone know the code?
I have used the search button to attempt to find the answer, however that proved fruitless. I know i have seen it somewhere around here, but I just can't find it again.
P.S. Does anyone know if you can import a .txt file from the net if it is imported into a .exe file running on a computer? The computer would have a connection to the internet at the time. would I just put an absolute path into the file parameter? Like: [URL]
