ActionScript 3.0 :: Array Elements Knowing Their Index Number ?
Jul 8, 2011
Say you have a class Parent, which has a property childArray:Array. In this array, we will register several instances of the class Child. Is there an easy way for a child to know which position in the array it currently has? I know I could just pass the index number into the child as I register them, but if a child were to be deleted from the array, all children past the deleted childs index would need to have their indexes updatedl. While this is of course not a huge task, I just have this feeling it should be a better and more dynamic solution.
I have a ComboBox, with it prepopulated with the States.When I have a variable that says it should be pre-selected to for example CA, how do I do that, without haveing to figure out the index number for every single state?
I am trying to trace an index number from an array.
I know this must be about as simple as it gets, but I just cant figure it out.
I know the contents of the array are all asighned a number begining with 0.
I need to find out the index number of a thumbnail when you click on it.
Code: function whenThumbsLoad(event:Event):void{ var thisThumbsLink:String = clipPathList[ c ]; var thisThumbsTitle:String = clipTitleList[ c ];
[Code].....
I know I can trace the thisThumbsLink and get that, but all I need is it's index number. Also I trace(c); and I get how many there are, but I just don't know what to trace to find the index number.
i used a for loop to addChild of a class object(movieclip) to the stage and at the end line of for loop after addChild i push it into an array and i add eventlistener to it , such as
for (var i:Number = 0; i < 9; i++) { ..... clip = new CLIP; ......
[Code]....
and if i want to get the array number which currently accessing how can i do that ? for example, i drag one of the mc class from the array which has already added eventlistener above.
how can i get the number of the array which im accessing ? evt.target..... etc ?
The Action script code below takes the strings in the array (pgtit) and creates a dynamic navigation bar I am trying to trace the index number of the array being click I just seem to get -1.
var pgtit:Array=["link1","link2","link3","link4"]; var xPos = 0; var menuHolder:MovieClip = new MovieClip; addChild(menuHolder);
i have a tree component that dispatches an itemOpen event. When the black triangle next to the yellow folder is clicked, that folder opens to expose its children.
Is there anyway to know the index of the open folder? there is a rowIndex property in the target property of the openItem event that stores the index but it is not accessible.
my_Array = new Array(); my_Array.push("one", "two", "three", "four")
Here's the catch: another variable (for instance) called "three" is loaded. I want to look up "three" in my_Array and retrieve the index-number (should be 2 of course). How can I accomplish that?
I have been working with flash remoting in actionscript 3.0 and there is no result set class. I'm fairly new to AS3, but I am very fluent with AS2, and so far the migration has been easy.I would like to create a result set class myself, but I am stuck on one part, pushing the dynamic number of elements onto the array, let me show you what I mean:
{ // start result function var totalCount:Number = rs.serverInfo.totalCount; // # of records returned var queryString:String = rs.serverInfo.intialData; // query string, each value separated
I am using an array to return data to an application and as the array is filled with data using a loader and the order is important it happens that data in slot n is inserted later than data in slot n+1. How do I know that the array is full as I know the number of elements to be loaded? The length property doesn't work for this. I could go through the array each time I put something in and look if every slot is full but that seems ineffective.
I just read the tutorial "Finding Values in an Array". Sure, the code works, but that's only because we are searching arrays the contain a small number of elements. Suppose we have n elements in an array. To search that array for a particular element we may have to do n comparisons. If the array we are searching contains 10 million elements, we have a problem; can you imagine doing "if (this == that)" 10 million times? There's got to be a better way to search the array. Or perhaps we shouldn't use arrays to store the information.
[code]I want to input a number and find a match for the number, returning the values on the row in to specific fields for each number. For example, if I input the number 10 in an input field, I want the number 1.2276, 0.00100, 106.38 and the rest of that row to output these values I have seen so many options, don't know where to start.
I have used a method to shuffle a part of a Array, but i noticed that it does not work very well.When i run this method I sometimes get empty array values.So if you would try the example below and test it out some times you would get a right result but sometimes a wrong result.For example when i run this i get in my trace output:
a,b,c,d,g,,e,f (here after the g it goes wrong) a,b,c,f,g,d,e (here it goes right) a,b,c,d,,g,f,e (here it goes wrong)[code]...
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..
//*//*//*//*//**//**/**//**//**//**//**//**//**//**//**//**//**// var t:Array=new Array();t=[d1,d2,d3,d4,d5]; var d:Array=new Array();d=[t1,t2,t3,t4,t5];
I want to know the index number of the object when I clicked it.. trace(mc.getChildAt(0)) = display the object at the index 0 lets say the output is [object] button Now I want to reverse it. When I click the object button button.addEventListener(MouseEvent.CLICK, onClick) function onClick(e:MouseEvent){ trace(e.currentTarget.????????) //I want to trace what index number is that button, the output should be "0" }
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 have a flash file that loads in a external swf. That swf contains a form that I want to control the tab order on. The external swf has form fields in it, and I have their tab indexes set. When I hit tab, flash ignores the flash index, and focuses on some of the navigation elements of the parent .swf. What am I doing wrong?
If myXML.person.length() gives me the number of person nodes in my XML file, then how do I count the number of elements inside each person node if each one has a different name (such as address,zip, etc.)?
Is it possible to define a property to limit the number of elements which will appear in a mx:List ? I've read about setting the property rowCount, but I don't see any effect.Can a filter be applied to accomplish this? My intention was to avoid removing the items from the list/array collection, but simply "hide" them. Can this be done?
Simple question i can trace all elements from xml but how to trace 5 or 15 or any number (that you enter to input text field) of random elements from xml file
