ActionScript 3.0 :: Remove Empty Elements In An Array?
Nov 9, 2009
I'm working with SWFAddress and I have a split function but its also adding empty elements to my array which I want to remove or stop been entered in the array.
Code:
var str : String = '/home/'
var split = str.split("/");
trace("split = "+split.length);
tracer.text = split;
output : ,home,
As you can see the split is coming back with 2 empty elements in the array.The string value could change depending on what the user enters into the url for deeplinking. It could be var str : String = 'home' and this returns the correct value but if the add a slash I need to make sure that is not registered in my array as an empty value. how I could stop these empty elements from showing in the array?
I have an array that has 158 elments. When the array is traced several come up as undefined which I expected but I wont to remove the undefined elements in the array.
If i have array like var my_Arr:Array = new Array("a", "b", "c");and i have button to use random element of ths array , is there any to remove that element that if i press the button again i won't find the last element ?
I'm writing an application in Flex / ActionScript and have a number of class member variables of type Array storing data. My question is: what's the "best" way to clear out an Array object? I noticed the ArrayCollection class has a function removeAll() which does this, but the basic Array class does not. Some possibilities I've considered are: Iterating through the array, calling pop or shift on each element Setting the array length to 0 Setting the member variable to a "new Array()" or "[]"
I noe how can I remove all elements in an array? I got a quiz where it will store the questions which the user has answered wrongly in an array n when the user press the "try again" button, he will go back to the first question again. I want the array to b reset n restore the questions tat answer wrongly again
For instance: tempArray = new Array(); tempArray.push(dom1);
I am trying to clear out an array but it isn't working how I would like. What function clears elements from an array?Also I have had trouble removing children.It leads to strange error messages, any hints or tutorials on clearing children?
Let's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.
I have a list of 99 item (something like a phone book) and I will like to sort them in different method. Part of the 99 item might be empty, so the requirement is to move the empty field behind the sorted data in every sorting behavior, here the code we have so far:
I've got a fairly simple flash app that searches an xml file and returns text listings of the content of the childnodes back to a dynamic text box for display. The xml file will be edited and managed by an outside user. It works great but if there's an empty childnode (element) it comes back in the list as undefined. I'd like to be able to leave the xml element format the same for the user whether it has text inside the element or not. If it's left empty though, I don't want it to show up. I've seen several ideas on how to handle this but was wondering what the best and most simple solution is.
I've been trying to move array elements from one array to another using the push method. The problem is that the element pushed should any longer be on the first array where it was taken from. That's where i'm stuck..
I'm making some kind of rssreader right now... everything goes really well but the only thing is that when i read data from xml i get some empty lines in my text. like this:BAJKONOER - De Europese ruimtevaartorganisatie ESA heeftwoensdagochtend de Europese ruimtesonde Venus Express gelanceerdit just stops after "heeft"... it seems like a normal return... but how do i get it out of my string?
If I am a subclass of an Array, how do I access an element?
class ArrayOfFoo extends Array { public function getFooAt(anIndex : int) : Foo { return this[anIndex] as Foo; // <---- looks for an object attribute (named "0", for example) } }
I could wrap an array instead of subclassing it, however lacking a universal IArray interface, that is less than useful for standard and custom functions expecting an Array.
I'm using a spark combobox (which I really like). What I'd like to do is to allow users to delete elements from the cb list. To do this, I thought I'd add a delete button next to each cb element, by using a custom (and extremely simple) itemRenderer.
I have a big ArrayCollection variable. I want to filter it serveral times and each time assign the filtered result to a different ArrayCollection variable.
So if it has let's say people, fruits and cars. (for illustration purposes) I want to first filter it to only show people, assign the result to a people ArrayCollection, then filter it to show fruits and assign it to a fruits ArrayCollection and so on.
How can I do that? Not the filtering, but the assignment after filtering. Or is it faster to instead run a for-loop through the big ArrayCollection and just add each item into the corresponding smaller ArrayCollection?
I'm making a custom webbrower by Adobe Air.I would like to add a html filter function that disable javascript & iframe.If I can get html code before render, I would delete tag elements with regexp.I guess I can something with htmlloader when htmlloader's LocationChangeEvent dispatch.
Would anyone be kind enough to help me with some Actionscript code (2.0) that will automatically remove from dynamically imported html text. Basically an html page is updated by a client using a CMS system (CushyCMS) but it inserts.When the page reloads into the flash site the cause the text to break.So I would like something that either removes the or changes it to a single space that won't cause the line to break.
I have a multiple choice quiz designed for a client. I have an array that works thruout the questions, that if the user answers incorrectly, it stores the question number in the array. When the user reaches the end of the quiz, I dont want this array to always display at the end, since the user could have all the asnwers correct (which means the array should be empty). I am trying to make an if else statement that will display a different message if the array is empty.[code]...
It only seems to work if I provide a value (which I am trying to avoid). What I would like for it to do is send the url param: myObject[array_list][]=& (i.e. an empty value)
I'm trying to make a question game with 30 question divided into 3 dificulties, so i'm using arrays to have my questions randomized but not repetitive.
I made the code use the first parameter of the array (array[0]) then remove it from the array.
So, my array will have no more elements after a time. But, when my array have only 1 element, i cant play this element, and i need to use the representation of the empty array to get it to play.
I'm new on AS3, so this may seem very confusing. Here is the code I used.[code]...
I've been programming a simple shopping cart. The system has several product categories, and in each one, appears a list of products. Each product listing has a numeric stepper, for the client to put desired product quantity.
Now I have two Arrays (lets call them "arrayCat6" and the other "arrayEncomenda6"). arrayCat6 tells me the quantities for each product, even if the quantity is zero. The other is supposed to put only those whose quantity is different from zero.
The question I have is that, if in the products you choose two products, that have another one with zero quantity between them, the arrayEncomenda6 will have and empty entry, between the two products, and I don't understand why. Both Arrays are refreshed each time the numericstepper (of any product) is pressed.
Please does anyone know if this is a bug, or am I forgeting something. The code follows:
function actualiza6(event:Event):void{ var parcial:Number=0; var aux_preco:String;
How do you empty an array. I want the array complete empty, so the array length =0. I have tried this code, but that doesn�t take away all elements in an array, just a few.
for (i=0; i<myArray.length; i++) { myArray.pop(); }
