Flex :: Best Way To Remove All Elements From AS Array?
Sep 25, 2009
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 "[]"
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 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'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 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?
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.
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.
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.
Example: var arr_1:Array = new Array(); arr_1.push({sdate:"2010-02-02",status:"New"}); arr_1.push({sdate:"2010-02-03",status:"New"}); arr_1.push({sdate:"2010-02-04",status:"New"}); arr_1.push({sdate:"2010-02-05",status:"New"}); How can I change element number 3 status to: "Old", without removing it. Just update the status value??
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 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.
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(); }
In a fla file (flash8) I added an "Input-text" naming the var: "varInput", and selected "Numeral [0..9]" from "Character Embedding".I added another input object, this time of "Dynamic -text" text type naming the var:"varOutput". I also added a button naming its' instance name:"btnDisplay".In "actions" panel I wrote the following [code]....
I´m trying to order elements of an array. When the dates come from dynamics text it´s no problem, bad when come from input text the dates are treated like strings and it´s impossible to order correctly, because 15 is considered less than 3. In both cases I can operate correctly whit this dates like numbers.How is possible to order this dates from input text, like numbers?
I have array with 5 boxes. I show this boxes on the stage + showing it random. Now I want add events for this boxes. For example if I click to box1 I must go to 'p4', if I click to any other boxes I must go to 'p3'.
I try to make the same like for buttons, but its not working: classNames[0].addEventListener(MouseEvent.CLICK, goCorrect); function goCorrect(event:MouseEvent):void { trace("p4"); gotoAndStop('p4'); [Code] .....
is there an easy way, using 1 or more for loops, to hit test every object in an array against every other object in that array. So I've got an array of 6 things
I need to access the elements of an array that is declared in the main swf(_level0). But I need to change it from another swf.How can I do it??So far I have this:
MAIN SWF:
var vector1:Array = [biblio_vid1, biblio_vid2, biblio_vid3, btn_1_4, biblio_vid4];
OTHER SWF:
var vector2:Array = _level0.vector1.slice(); trace(vector2); // undefined,undefined,undefined,undefined,undefined
I'm getting the following error in my compiler when I run this, even though it does exactly what I want it to do.

TypeError: Error #1010: A term is undefined and has no properties. at boxes070909_fla::MainTimeline/drawboxes()
I'm more interested in understanding why the error is occurring and how to correct it, than rewriting the code in a way that I don't understand it anymore.(Which was my friend's solution)
box_mc is an 80x80 grey square movieclip, of class Box.

I have a small array with some elements and a big array with all the elements. I want to search in the big array the small array to see if they exist. Is there a function to do that ?
