Actionscript 3 :: Reordering An Array Collection Based On Another Array Collection Hierarchy?
Sep 16, 2011
I have an array, crewPositionsAC that contains a list of position abreviatations - EP, PR, DR, WR, and so on. These positions are read in through an XML file each time my flex application loads. Also being populated from an XML is a project. Within a project, there are positions (a student assigned to a type of position listed within crewPositionsAC). These positions are not necessarily in the correct hierarchy order dictated by crewPositionsAC. I have all the positions within an ArrayCollection (positionsAC) with the following structure:
Then, the user can click a button to add another position. When the "Add Crew Member" button is pressed, the user is presented with a list of possible positions to add. Currently, I simply add another array to positionsAC. This results in the recently added crew member to placed on the bottom of the list. I need to take positionsAC and reorder it based on it's [2] item (role) based on the hierarchy defined in the crewPositionsAC. crewPositionsAC has the following structure:
crewPositionsAC:
[0] = EP
[1] = PR
[2] = DR
[3] = WR
* continue until all possible position types are listed
In my flex application im using two datagridfirst datgrid is for items collectionssecond is for bank details.if i click one row in first datagrid (which has the items collections)...a unique code is taken from the grid(which is primary key).then, i have to select two or more banks using itemrenderer checkboxes in second datagrid(which has the bank details)ow, have to bind the bank details(one or more banks) with that one primary key in first datagrid. to an single array collection... and have to show it in another new datagrid(thirdone)
I have an array collection of strings and integers (which I have displayed in a data grid) and I am wondering if it is possible to export the array collection into an html table? or even a text file for the user to download
I found some pages that had an export to .xls files but I want to stray away from that for now.
While making my choice b/n Array and Arraycollection I get confused why whould I use one and why not another. I have read the theory in langref but apart from that is there some general advantages/disadvantages of one over the another that you have learned from your experience.
i have a simple array, for example: ( 50, 20, 60, 30, 10, 8, 15, 25) but need to output it in ascending numerical order ( 8, 10, 15, 20, 25, 30, 50, 60 ). Any one have a handy code snippet to do so?
I have an application that takes some database info and shoves it into a datagrid, or chart. I've come across this error of having a single row and trying to use it in an array so I can use it in my app. Its come to my attention that its a pretty common problem that people face, but I don't seem to be able to get around it no matter what a try. My actionscript has a fucntion that trots of to the database via ASP, and returns the data in the event - as below (obv i've removed some stuff - load of calls are made to the mssqlQuery function - only the one I have trauma with is below)
From what I know the whole idea behind having collection classes is introduce extra wrapper methods which will be handy for developers.
Then why does ArrayCollection in Flex not seem to have some methods that array has. ArrayCollection does not have a copy, concat, join or splice methods which return a new array so we need to do the copy manually?
Im trying to populate a tree control with an external xml file brought in via arraycollection but i need to group the xml data to display in the tree Okay my external xml file is called parts.xml and it looks like this:
[Code]...
additionally what i intend is for the user to have huge tree of parts and they select a node at the partnumber level and drag an drop it on to a datagrid where all the other tags of the part gets displayed.
Ive tried and tried many things without any luck. even now im thinking maybe if i looped through the array-collection and created a new array just for the tree to get it to display the way i need it, then when the user dragged and drop a part onto the grid i would have code that would look for that part number in the original arraycollection and add it to a new array just for the datagrid... i still dont know how i would create that new array for the tree!! cause the xml data is grouped by partgroup and then grouped again by parttype before you get the individual part numbers
I have an array collection that I would like to limit to say 100 items. I tried setting up a filter function where the return was:return (myAC.getItemIndex(item) > 100);but the value was always -1. For whatever reason it couldn't find the item, even though the item is definitely there.I'm able to do this with a while loop:while(myAC.length > 100) myAC.removeItemAt(100);
I have two xml files, defect. xml and employee.xml. But the files havea common field but with different names in each file. I want both the files to be merged in to a single array collection.
The structure of my defect.xml file is:
<defectList> <defect> <revId>123</revId>
[Code]....
Now, if I give datafield as "employeeId" in the datagrid with defectList as dataprovider, I get the employee id of the corresponding Employee Name.
I've got an XML Doc loaded in. I've created an Horizontal List and referenced the arraycollection as the Data Provider. But what I need to do now is then pull the data out from that. I have 3 nodes / variables. They are id, title, thumbnail. But when I go to pull through the data as : {videos.title} Flex Builder gives me the Error - "Access of undefined property videos". Now I know full well it exists, as when I set the dataProvider to {videos} it pulls through the data without issue.
My code is as follows : <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="[URL]" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="800" minHeight="600" [Code] .....
How do I go about getting the XML Node : title and of course the thumbnail too?
I have an array collection set as a datagrid's dataprovider. I'm pulling content from my relational database and 2 of the columns in the grid appear as foreign keys.
How do I go about replacing the foreign key id with information from the other table?
I'm guessing I need to do some sort of: for each, but I'm really not sure how.
I want to sort an array collection in a way that I am not sure is possible.Usually when you want to sort you have something like this.[code]if a is the same in multiple classes then I want to sort on ToSortInner2.aa Is this possible. I have tried to pass in inner1.aa as the sort field name but this does not work.
In ActionScript I have string as str="subject,r1,r2:a,b:1,2:3,4"; Dynamically I have split this string and build array collection as given below arraycoll.addItem({subject:a ,r1:1,r2:3}); This example of one set. The array collection should be built dynamic. I have tried but not successful.
I used var dp:ArrayCollection = new ArrayCollection(container.GetVotesResult); to get the JSON data from GetVotesResult method. I get the values as below.
[Code].....
How do I retrieve the 2nd, 3rd, 4th and so on (if it has) array datas individually and dynamically. Say, I want to take 'Atext' from all the array.
I'm new to actionscript but have some basic programming skills. I've downloaded some code that finds and displays fields from an attribute table of a feature, from my limited knowledge it seems to be adding this data into an array collection, the problem is I need the data fields to be displayed in alphabetical order, or in the order they are originally stored. I tried to use the sort function to order the array but can't get it to work.
The source code is below: <mx:Script> <![CDATA[ import com.esri.ags.events.DrawEvent; import com.esri.ags.events.IdentifyEvent; import com.esri.ags.geometry.Extent; import com.esri.ags.geometry.Geometry; [Code] .....
I'm using zend_amf and flex. My problem is i have to populate my advance datagrid using array collection. this array collection have a children.[code]...
I want to give an array index to array collection let say 205 when it is started is it possible to do so in flex or any alternate of this.actually I need to index the objects with a specific no, in 2D array collection
say
205 a c d g f d 268 s g h g f f 805 d g h h f f d
where integers are indexes and alphabets are object referenced by these integers
I am trying display values in a datagrid in my application. I have all the values as an xml file. I had only one set of record n the XML file, to fill only one row of the data grid. While trying to store the values from the XML file to an Array Collection in the application File using the code, i.e.,
I get an error, saying Error No# 1034: Type coercion failed cannot convert mx.utils::ObjectProxy to Array.But If I have two record sets in the XML file, it works fine. If there is only one set, I gHere is my xml file:
