ActionScript 2.0 :: Handling OnRelease With Return Val?
Oct 18, 2010
Have been dabbling with flash for few years, but would like to send data to external PHP file and would like flash to process response.The way I have it working is to register function for the submit button on the main stage where I have the form instance. However, when I do this, it stops rollover effects from working on submit button. (The button is actually a movie clip instead of straight forward button btw.)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~
Form code below:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~
When you click on the movieClip "purplebow" the animation starts, and when you roll off it goes back to normal. What I would like implementing some code into this so that my other movieClips (which are: bluebow, redbow, greenbow, etc). Disappear onRelease and then return onRollOut. The code and the movieClips are all on the same timeline, each on different layers.
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):
I am trying to get metadate from my NetStream object and do things depending on what is going on. here is what I have, but I get an error I don't know what it means.
var customClient:Object = new Object(); customClient.onMetaData = metaDataHandler; function metaDataHandler(infoObject:Object):void {
[code]....
The error I get is:Error #2044: Unhandled AsyncErrorEvent:.text=Error #2095: flash.net.NetStream was unable to invoke callback onMetaData. error=TypeError: Error #1010: A term is undefined and has no properties. at AMG_ASP_ICS_072709_fla::MainTimeline/frame1()
How do you communicate an error to the web service consumer ?
For example, my web service has a function to insert employee into db.Suppose while inserting the data , the database gave an error,what should be the best way to inform the user about the error.
One way is to depict it through the return value of the web service method but what to do when the function is supposed to return a complex object like employee when there is no error ,and will send an error string when there is an error ?
I have a bit of code listens for a user to click a navigation item, however if they click another nav item then my code loads both of them and puts the content pages on top of each other.I am having loads of problems with this bit of code.
PHP Code: private function _menuSelectHandler (event : MenuEvent):void { if (! event.abstract) {
I have a problem with event handling. I'm working on a calendar, on which events can be listed. With actionscript i loop through an XML file with the days (and if there, the events for that day). So far so good. Where it goes wrong is this: I only want to display blocks with the day numbers on it. When you click on a day, a box pops up and shows the event's for that day.
This is what i did: created a movieclip with classname mc. loop trough the xml file and for each day create a new instance of mc with the day number as text on it. This al works, but now i want to add an eventhandler for each day. How to do this?
I'm asking many questions these days but its really urgent
I am doing an application to load xml file into data grid and everything is done now. The only thing left is that i wanna make sure that if the xml file isn't there, the user will not have a runtime error.I have the following code to load the file.
var myXML:XML = new XML();var XML_URL:String = "questions.xml"; var myXMLURL:URLRequest = new URLRequest(XML_URL);var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener("complete", xmlLoaded);
i tried many ways i found on the net using try and catch but didnt work. Anyone can write me the peice of code to hande this error if the file is not there??
If I have a graphic that is fully transparent in places, can I make only the non-transparent portions of the graphic respond to mouse clicks? I realize I can probably do this with a few lines of code, e.g. detect the click and then check the alpha value under the mouse. But I was looking for something simple. For example, in Director there is an "alphaThreshold" in a graphic that determines at what alpha value a bitmap will respond to mouse clicks. Does Flash / AS3 have a similar capability?
I'm working on a game, that loads up external text files to create maps. There is a error if the player moves out of bounds, and there is no map to load. All I need is a sort of check to see if the text file actually exists, before loading it
I'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):
I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.
We have a Flex client and a server that is using the Spring/Blazeds project. After the user logs in and is authenticated, the spring security layer sends a redirect to a new URL which is where our main application is located. However, within the flex client, I'm currently using HTTPService for the initial request and I get the redirected page sent back to me in its entirety. How can I just get the URL so that I can use navigatetourl to get where the app to go where it needs to?
I am building a Flex application using Pure MVC pattern and Zend framework for calling php code on the server. I need to sync some data with my server which is using MySQL as the database. And there are 5 such tables I need to sync. So I call these php functions at regular intervals from Flex and use long polling on php side. The client side code for my subjects lies in 5 different proxies.
Should I send 5 separate requests from each proxy to call the php code which is lying in separate classes. Or should I build a separate proxy to send 1 request from 1 php file and then distribute this data among different proxies on the client side. Which one will be more effecient? Mathematics shows using separate proxies and php classes allow more number of users to be accomodated on the server.Can I write 1 SQL command to fetch data from all 5 tables given they cant be joined on any column?
I'm building an application, where objects are attached on a canvas and the tree of that canvas is held on a tree component. Each time that i attach an object the tree adds a new child etc. I want to do this on the other way around.. I want to press a tree node and "communicate" with the specific object, so that i can change its color, delete it etc. I've tried some things but nothing happens!This is my code:
var working_space:XML = new XML(); working_space.addTreeNode("Canvas",0); myTree.dataProvider = working_space;
I have a very simple Flash movie with multiple keyframes. Each keyframe has buttons which I'll be attaching event listeners.
I was hoping that I could add all event listeners to all buttons in all keyframes by using a document class. This works for buttons in frame #1, but anything else gets a null reference exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I also tried adding a layer to the timeline that spans all keyframes and putting in the eventlisteners (and respective addEventListeners) there. Same thing - null reference exceptions for everything not in frame #1.
I'm used to building web apps using proper architectures, but relatively new to the RIA space.One of the issues in rich client app is approaches to handling communication across components. (I've played around using the EventBroker concept.)In a recent Flex3/AS app I was looking at they took an approach that seemed to work pretty well, but I wonder about the drawbacks (or any other pros)...They took the concept of having a singleton object that would hold objects that could be used obviously from any components within the app by a simple call to...
var myAppModel:AppModel = AppModel.getInstance();
You thus could put any objects in there that you wanted access to from different components. It seemed to serve as the equivalent of a "Session" in the JEE space. I'm not so sure from an OO perspective it's the best thing to do, but it did seem to work pretty well.
on clicking the Search Icon , a search bar will be visible (ON) if user click anywhere on the stage the search bar will be NO visible(OFF) OR user click on ICON again the search bar will be OFF but it Stage CLICK is triggered without clicking
Code: searchIcon.addEventListener(MouseEvent.CLICK, showSearch); var srchBox:Boolean = true; function showSearch(event:MouseEvent):void
I am trying to create an app that will read files form a local folder on a memory stick (flash drive) which the app will be on too, then I need to be able to move one of the files in this local directory to a specified folder on the system BUT there has to be a variable taken from a text input to complete something along the lines of
I have a class with a XML object in it. In one of the class' methods, I tell the XML object to load a document. Before I do that, I set up the onLoad event to call one of the class' other methods. The problem is that in that handler function, I can't seem to access any of my class' data. If I try to use the "this" pointer, I'm getting the XML object not my class.
I am getting a string from XML file in the above format which i am storing in original varible. But at the time of showing the output, I want values of the variables ( {sex} ..those are in culy braces) to be displayed which are their in array Data....like for sex value is M ..for name it is xyz...etc...and the values should be displayed in a format defined in the strring....so how do i create a new string which would look like this...newstring="M<b>xyz</b>1/1/00"
Code: // msg_box_txt is a TextField for user input // by hitting ENTER, it sends msg_box_txt.text var my_listener:Object = new Object(); my_listener.onKeyDown = function() { if (Key.getCode() == Key.ENTER) {
[Code]...
msg_box_txt should be cleared, empty, after hitting ENTER. the problem that it contains one empty line, and the cursor is at beginning of the second line. how can this be fixed??
I've developed an FLEX application for distributed data administration. When our Asian employees specify a date, it will be saved +1 day.If I check my timezone offset it is +60, their offset is +520.
var dNow:Date = new Date(); trace("Your time zone offset: " + dNow.getTimezoneOffset() + " minutes");
I assume this is the problem? If so, would you suggest that I correct the entered date by 460 minutes before sending it to our server for saving? How to do that?
Code: import flash.display.Sprite; var sp1:Sprite = new Sprite( ); var sp2_1:Sprite = new Sprite( );

I'd assume from this that there is no correcting done for children with the same name being added to the same parent. I ask this question because I'm creating a structure that needs to mimic the display list and I'd like to keep behavior consistent.
Another question: I'd assume internally the children are saved in something similar to a Dictionary object, does anyone know if this is true? And then getChildByName simply does a foreach loop and returns the first match on a name?
I am having mainly 2 problems in Flash for some time and I need some clarifications on them.
1. Handling pages. How do I handle working with pages in Flash? Do I create a frame for each page and place the content of the page in that frame and when needing to go to a page I simply go to it's frame? Or do I use ActionScript to put and remove content from the stage and create every page in this way? What I mean by this is: if a page has a menu and a picture, I use ActionScript to put the menu and the picture there. If the next page has some text and a button, I use ActionScript to remove the menu and the picture from the last page and put the text and the button from the new page.
The first method seems simpler but that means that if the page has some content that needs to be loaded (a picture, for example), this content will need to be loaded every single time the page is opened.
The second method requires more work but is it more efficient ? When I remove the content from the page, do I move it to a negative x and y so that it cannot be seen or do I remove it completely and just load it again the next time the page is opened?
2. Handling a flow communication with PHP. I constantly need to communicate back and forth with PHP. I use a LoadVars variable to send data to PHP (using "POST") and I use an XML variable to retrieve data from PHP (I use the "sendAndLoad" method). The data sent by PHP is in an XML structure. The problem here is that I need to have different channels working. I need to receive several different types of data. Do I create a set of LoadVars and XML variables for each type of data that I need to receive or do I simply use only the one set and use an ID variable to specify with which type of data I am working at the moment ?
I've got a fairly simple flash app that searches an xml file and returns text listings of the content of the childnodes back to a dynamic text box for display. The xml file will be edited and managed by an outside user. It works great but if there's an empty childnode (element) it comes back in the list as undefined. I'd like to be able to leave the xml element format the same for the user whether it has text inside the element or not. If it's left empty though, I don't want it to show up. I've seen several ideas on how to handle this but was wondering what the best and most simple solution is.
What's the best way to handle the " symbol, dynamically written to XML output from a PHP upon request, and then pulled into Flash, parsed, and assigned to a String?Should the entire node's data be wrapped as CDATA in the XML document? But when when it gets assigned as a String in Flash, will Flash freak out because there's a " in it?Should PHP write escape characters into the node's text to escape quotes, ampersands, gt/lt, and apostrophes (and then will Flash handle these ok?)? Or should PHP convert all unsafe characters into their HTML equivalent?What about the British pound symbol? We're using UTF-8, so is there a safe way to handle this?
