Say I start at a leaf node, and I traverse up the tree by using .parent(). I need an exit condition once it hits root. At the moment, I'm using parent.@name != "root", where name is just an attribute, but shouldn't I be able to check the type of element as well? How? Also, is there another way to end the traversal in as3?

I'm trying to check if a clicked element is inside of an IVisualElement in Flex 4. So I want something like "if this element is in this element, then execute function". I'm aware of the 'parent' property but this doesn't seem to work when my element is not a direct child of the element but for example 3 levels deep.

I'm trying to figure out how to add an element node to my XML, but can't seem to figure out how to do it.
i.e.
var zoo:XML = <zoo>
<section>
<animals>

I am stuck on how to make these changes to an xml using AS3. My xml structure is as follows
Code:
<boys>
<boy>

I have a entire XML and I've already loaded it. How do I get a specific node? For example:
<images>
<image url="" label="" etc=""/>
<image url=""/>
<image url=""/>
</image>
I need to pass the entire node through params
Like this:
var node:XML = xml.images[0];
trace(node); // <image url="" label="" etc=""/>
Is that possible?
I have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.

I have a MC that pulls in XML data. The data it calls is content and a link. To make the MC launch the link I'm using the "onRelease" function. The MC pulls in the data from the content node and the data from the link node just fine. The problem is when my client just wants content without a URL the MC still keeps the "onRelease" function, so the content (that shouldn't be linkable) is still clickable and launches a "error" page.I'm trying to disable the "onRelease" function by checking if the URL node has data in it but I can't figure out a way to do this?THIS SCRIPT IS WITH IN THE MC:
function loadXML(loaded) {
if (loaded) {
_root.linkName = this.firstChild.childNodes[0].firstChild.nodeValue;

this line gives me error like following line :Element type "components" must be followed by either attribute specifications, ">"
checking an XML file for a specific node.
Example:
<vid
flv="videoName"
thumb="thumbnail.jpg"
title="Video Title"
[code]....
The first vid node contains a path to a logo graphic, I then need to check in my ActionScript if there is a logo there or not, and to do something if there is(display the logo) I can trace out the logo path so I thought I could run a simple if/else to check if there is anything in that node and if so to do something:
private function thumbOver(e:MouseEvent = null):void
{
trace("
");
[code]....
Now I've tried everything, but it will always trace out "Does have a logo" no matter what I do. I tried:
if (tabData[tabID].video[e.target.id].@logo == "")
if (tabData[tabID].video[e.target.id].@logo == null)
However I get the same results?
check to see if a node exists in an XMLList object. I have a list of objects to convert to XML, but if an xml entry already exists, then the following objects with the same name get added as children.

View 2 RepliesI can get all the normal nodes of my rss parsed fine but there are a few nodes that I am having trouble with. In the code below I can pull the info from "<item>", "<title>" and "<description>" but how would I go about pulling the info from the node "<enews:url>" ?

Code: Select all<item>

View 1 RepliesHow do I check if an element in an array exists?
I'm looking for something along the lines of this, but don't know the proper syntax:
ActionScript Code:
if(array[5].exists()) {
// Do something.
}
else {
// Do something else.
}
Well, I looked at the example, and looks like that was still not what I wanted. Interestingly, I took the middle for loop out and now it appears I am not having issues anymore.[code]
View 7 Repliesis there a way to check an array to see if an element has already been added? I'm working with an XML document where there are 4 possible variables, but these 4 vars are repeated several times over. It's reading in fine... I just want to pull those specific variables out of the XML and add them to an array, but I do not want them to duplicate. To say it another way... I don't want my array to be more than 4 items long (it is possible to be less) with a max of those 4 different vars.

In most browsers, when you have one in focus and you type something, the combobox will try to find the value within its options and show the closest one. I was wondering what kind of algorithm is used for that.I don't think its Levenshtein or similar since it only works with the beginning of the string.I'm thinking that it works by keeping a buffer of what has been written, and tries to find a string starting with that... if it doesn't find anything, it clears the buffer, and searches a string beginning with the last character pressed.I already prototyped this, and it works quite ok, with one caveat... In HTML, when you repeatedly press the same key, it will rotate between all options starting with that character.

I have two objects [object MovieClip] [object ContentDisplay]
i have to differentiate them abut i can't find a method in as3 check variable type.
The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?
