JavaScript :: Removing Items From Data Bound Array
Mar 26, 2009
How do I remove an items from a data bound array? My code follows.
for(var i = 0; i < listBox.selectedIndices.length; i++) {
var toRemove = listFiles.selectedIndices[i];
dataArray.splice(toRemove, 1);
Here is my swf. The Add Photos works except when you remove items. [URL]
Add 3 photos different.
Remove 2nd photo.
Add a different photo.
SWF adds the 2nd photo to the end.
Here is my code
private function OnSelectFileRefList(e:Event):void {
Alert.show('addstart:' + arrayQueue.length);
for each (var f:FileReference in fileRefList.fileList) {
var lid:ListItemData = new ListItemData();
lid.fileRef = f;
arrayQueue[arrayQueue.length]=lid;
[Code] .....

I could pop, shift, splice or slice it out of there (hey, that had a nice ring to it...)
how to properly remove items from an array while in the middle of a for loop:
Code:
//This will cause errors, because if the condition is met, it will skip the next array in line
for (var i:int = 0; i < arr.length; i++)

If someone is reading through my code, will they understand what I am doing without me having to clarify with comments each time?

I have an arrayCollection with the following structure:
[Code]...
the AC is defined as follows:[Bindable] private var projectErrorsAC:ArrayCollection = new ArrayCollection;
I'm using this AC in a repeater to display each error. After each error is shown, I've placed an "Accept" and "Deny" button. Once the user clicks either one of these buttons, I'd like to call a function that removes the particular error from the AC. Here's what I have so far:

Each item in the array in on the stage, each with an x/y position. The item in the top left most position should be items[0]. X should be the primary. Originally I was thinking along the lines of:
var items = [m1, m2, m3, m4, m5, m6];
items.sort(sortMe);
function sortMe(a, b) {
return (b.position[0] - a.position[0]) && (b.position[1] - a.position[1]);
}
But this does not yield the correct results.

I have an array that has 30 date objects. The date objects are indexed in the array from the minimum date value to the maximum date value. What I would like to do is retrieve only 7 dates from the array. Out of the 7, the first one should be the minDate and the last should be the maxDate, with 5 dates in the middle. The 7 numbers should increment evenly from the minDate to the maxDate.

I have a DataGrid bound to an XMLConnector and XMLDataSet. The XML data loads fine into the components. However, I cannot get the value of the selected index using: my_datagrid.selectedIndex
The call works fine if you use addItem to populate the grid.
Is there an issue being that the datagrid.selectedIndex parameter is bound to the XML components?

I have an ArrayCollection bound to an editable DataGrid, another component needs to know when the ArrayCollection changes (as a result of changes in the DataGrid) so it can also update itself, so is listening to the COLLECTION_CHANGE event of the ArrayCollection.
The problem is that the DataGrid only updates the ArrayCollection when the row being edited losses focus. This is not good for my app as a user could edit a column on a row and not click elsewhere on the table for a long time (causing the row to lose fucus), therefore the changes won't have propagated to the other parts of the application.
How can I make the data grid inform the ArrayCollection of a change every time there is a keyup event on a text input instead of every time a row looses focus?

I'd really like to be able to make Flash's array access syntax 'wrap' over the array's bounds.
Lengthy explanation -
var array:Array = ['a','b','c','d','e','f'];
To keep things simple, the first index is 0, and its value is the first letter, 'a'. To get that value, we'd do this -
array[0]; // returns 'a'
As long as the index you're using to access the array is between 0 and array.length (6 in our example,) everything works fine - but if you use an index outside of those bounds, you're shut down.
array[-3];
array[9]; // both return 'undefined'
Sometimes that's a good thing - sometimes you expect that to happen, and you're fine with it. Other times, you find yourself wishing (or at least I find myself wishing) that it'd behave a bit more like this -
array[-3];
array[9]; // both return 'd'
(e.g. a photo gallery that jumps back to the beginning when you click 'next' on the last photo)There's a little chunk of code I use over and over for this sort of thing, but it's always to alter the index before passing it into the array:
var index = -3;
while(index < 0){index += array.length}
array[index % array.length]; // returns 'd'
... and that's fine, but what I really want to do is extend the Array object itself so that it'll automatically 'wrap' index values that go out of bounds.TL;DR - Is index-wrapping possible by extending Flash AS3's Array object?

The following for loop removes children from their parent if they're in the display list. It works correctly, but I also want to remove each child from memory with the same loop.

Below is a function set that's used to get info from an XML source(s) and populate a List Component (videoList). Works great. The second function loads data from a separate XML source and populates the SAME List Component. When the second function is called it loads the data in addition to the existing data into the List Component. I want it to REPLACE the data. How would I accomplish this?
public function getXMLdata(event:Event):void {
var campXML:XML = new XML(xmlLoader.data);
var vid:XML;
for each(vid in campXML.vid) {

I am adding few items dynamically from the library to the stage by creating instances. If I remove them using removeChildAt() then the item gets removed from the display but exists in the memory. How can I remove this from memory?

I have a Listbox whith a ArrayCollection as datasource. I'm trying to remove the selected items from the ArrayCollection to update the list.Here is how I coded the remove function:
for each (var item:Item in theList.selectedItems)
{
theArrayCollection.removeItemAt(theArrayCollection .getItemIndex(item));
}
This works fine as long as the ArrayCollection is not sorted. When I apply a sort I get a RangeError from ListCollectionView.removeItemAt.

I have a large swf that is embedded in Director as a sprite I now want to put it onto a web page, so file size is critical Is there a way to remove unused library items when publishing so that file size is reduced? Is there another way to compress the swf so it is much smaller?The current size is about 25 Mb.What about streaming the swf?I'm not talking about streaming video or audio, just any Flash content.In Director, there is a way to right-click on a cast member and choose "find in score".If something isn't found it means that it either is not used in the movie or is implemented through code

I want to iterate over an ArrayCollection in Flex while there can be items added and removed.
Since i didn't find a way to use a "classic" Iterator like in Java, which would do the job. I tried the Cursor. But it doesn't really work the way i want it to be ;) So how do I do it nicely ?
var cursor:IViewCursor = workingStack.createCursor();
while (!cursor.afterLast)

I have an ArrayCollection that is the dataProvider for a spark.components.List, which has allowMultipleSelection="true". There is a "Remove Selected Items" button which initiates the removal of all the selected items from the ArrayCollection upon being clicked.
I currently use the following method:
myList.selectedIndices.sort(ascendingSort);
// remove items, counting backwards
for (var i:uint = myList.selectedIndices.length; i > 0; i--) {
myArrayCollection.removeItemAt(myList.selectedIndices[i-1]);
}
where ascendingSort does what you expect ;). It works fine, and I know that it will always work.
However, I did take note that if I neglected the sort altogether, to my surprise the removal still worked. The reason for this turned out to be that, when the removeItemAt is called, the selectedIndices are correspondingly updated.
So my question is: Can one rely upon a removeItemAt call updating the values in the selectedIndices? or might that turn out to be different between runtimes and/or Flex SDK versions?

I have a list of 10+ items. when i click back up the list 1 step i call the code below to remove a thumbnail image associated with that list item.
if(indice < count-i){mx.core.Application.application.removethumb.dispat chEvent(new MouseEvent(MouseEvent.CLICK));
}
HOWEVER: I would like that if - for example i am on item 10 and click to item 4 - all the thumbnails between 4-10 are removed. it it possible to dispatch this click event X number of times dependant on the - count value?? FOR REFERENCE: THIS IS THE CODE THAT REMOVES ALL ITEMS BEYOND THE ONE I HAVE SELECTED:

I am working on trying to collect data within an array (which works) and this data is collected when a button is pressed or selected. I also want the ability to remove an item from the array if the button is pressed again. Currently, I have these buttons dynamically generated and everything works well. The buttons have ids applied to them. SO what I am trying to get working is, if I select button 0, 2, 3 (0 indexing), the data array created holds [A., C., D.]. I want to remove A. after I click button 0. Instead, it seems to cause problems. What I am doing wrong with splicing??? trace statement:
A. items so far selected
selected items are: 0
A.,C. items so far selected

I've discovered that you can disable annotations on embedded YouTube videos by adding the parameter &iv_load_policy=3 to the url in the embed code.
Example:
<object width="425" height="344">
<param name="movie" value="http://www.youtube.com/v/PMnEvKCtHBw&hl=en&fs=1&iv_load_policy=3"></param>
[Code]....
Is there any way to force this parameter on all YouTube embed urls on a webpage using javascript/jQuery?
(Sort of like this example where you force wmode transparent on all flash objects)

anyone knows how to pass an array values from an HTML into flash? Well, to begin I'll discuss what am I doing. I edited a twitter widget javascript which search tweets based on the hashtag I needed then passing it on an array per tweet and then displaying it using a <div> it updates once every 5 minutes. Now I want to display those tweets on a dynamic text on Flash. Let's say I will have 5 dynamic text placed on my flash file then; I want each of those dynamic text to have the tweets I have based on on my HTML arrays to be displayed in random.

It's a simple self-checkout grocery thing and I want to list the items the user is "buying" after typing in the appropriate code, but I can't get it to stay at nine lines only in the dynamic text field. I was told to use array.shift() to get rid of the first value in the two arrays so that I have an easy way by keeping the arrays at nine values, but it doesn't seem to work right.. It'll get rid of the first value, but only once and it'll add a blank value and then continue happily adding to the length of the array. Google has failed me so far so I suspect it's something else in my code.[code]

The as dictionary tells me I can use array.splice to remove an element from an array like so
Code:
var myPets_array:Array = new Array("cat", "dog", "bird", "fish");
trace( myPets_array.splice(1) ); // dog,bird,fish
trace( myPets_array ); // cat
Which is all fine an dandy, but what if I want to use a value instead of the index number?
like:
Code:
var myPets_array:Array = new Array("cat", "dog", "bird", "fish");
trace( myPets_array.splice("cat") ); // dog,bird,fish

I have an array containing single alphabet in every index and some of them in the array are duplicates. I'm trying to pick an alphabet and if there is an alphabet in that array, I want it remove from the array.
so lets say if i have 3 "a" in the array, I want all 3 to be remove. But my function only remove one alphabet. How do i make it remove all 3?
Also another question is, if i reach the end of the array how to i remove it? if i use splice it doesnt seem that it will remove the last item in the array.
my code is very simple
for (var i:int = 0; i<alphabetArrayLength; i++) {
if (singleAlphabet_arr[i] == alphabetPicked) {
answer = singleAlphabet_arr.splice(i,1);
}
}
