Flex :: Get Parent Form Textfield "enter" Event?
Nov 2, 2010
I'm not sure what the best practice is when attempting to "do something" with a form as a result of a user interaction - I'm certainly open to an alternative if it's the best practice.
There's an MXML event property called "enter" that applies to s:TextInput which calls an AS event handler when the user presses the Enter key within a TextInput field (imagine a Search field - you type in your search term and press Enter).
Now, within that event handler, I need to get at the parent Form object. Since we're talking best practices here, I'm not interested in referring to the Form by ID, in case my "enter" handler must be able to work with different forms.
My question is - what is the best way to get a handle on the event target's parent form in Flex? The parent-child hierarchy in Flex is absolutely ludicrous [code]...
The TextInput is initiating the event, and is the event.target. Following my MXML hierarchy, a logical chain might be event.target.parent.parent taking me from TextInput to FormItem to Form, but as you can see, the lovely skinnable Spark architecture puts all these other display objects and containers in-between.

I'm more of a designer than a coder but I'm trying to learn some actionscript. For my website which I build in flash catalyst I want to have a contact form. I have the form all ready.The only problem is when I tested it upon pressing the return key nothing happens in the message box would like the return key to go to a new line so that the user isn't writing in the same line.This is the code that I have:
bSubmit.onRelease = function(){ email();}function email(){ var sMessage = "Name: " + tName.text + "
E-mail: " + tEmail.text + "

In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.
I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.

I've this code for a form. Now I also want to put in like gotoAndPlay(1); if success How to do?
Code:
if (success) {
if (statusVars.sent == "success") {
clearForm();
statusMsg.text = "Sent";
I would also like to send the information in the form just by clicking ENTER instead of click a button, today the code look like:
Code:
bttnSend.bttn.onPress = function() {
checkForm();
};
How can I change it so it also check the form if the user click enter?

I've created several textFields, writing:
ActionScript Code:
for(i=0;i<=10;i++){
this.createTextField("texto"+i,i+1,100,100,100,100);
};
That's O.K. But I can't put a text in them... when I write
ActionScript Code:
for(i=0;i<=10;i++){
["texto"+i].text = 15;
};
It simply doesn't work!

I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.

I have noticed two differences between spark and mx forms which are causing me some problems. It seems by default the mx forms are arranged to the label is above the form input item. In Spark they are arranged next to each other. Also the label in spark forms are bold by default.For example MX code could be
<mx:Form width="100%">
<mx:FormItem indicatorGap="0">
<s:Label text="label1"/>

I have a search input textfield on stage that searches my list component...there is no search button, instead the search is performed 1 second after the user stops typing...(this is done with a key listener)...however the input focus gets stuck in the textfield if you type something (anything) and hit the enter key multiple times...I hit it like 5-10 real quick....then I tried to click my address bar in the browser, and I am unable to type a new URL...it just continues to type in the input text field on screen..

what I'm trying to do: I have an animation thats 173 frames long - an intro to a html based website. This swf file is embedded in the index.html, and is to load my "main-html", when the animation is complete.To try and do this iv'e tried with the following code in a blank keyframe in my as3 code layer on the last frame of the animation: [code]Upon completed animation it just goes into a frantic loop which seems to be trying to connect to my "main.html", but never have a chance to completely connect before it tires again.I have used similar code for my buttons, inside the page itself, which works just fine.

I have a button on the stage called enterCostBtn that when it is pressed it executes the code inside the calculateCost function. What I want to do is to be able to use the ENTER key on my keyboard to trigger that function. In other words I would like to be able to use the ENTER key or click directly on the enterCostBtn to trigger this function.
Code:
enterCostBtn.addEventListener(MouseEvent.CLICK,calculateCost,false,0,true);
function calculateCost(event:MouseEvent):void {
var material:Number=Number(Material_txt.text);
var labor:Number=Number(Labor_txt.text);

the code below is placed on one frame of the main timeline...it works, but apparently continually triggers the "gotoAndPlay" action over and over again. How can an ENTER_FRAME event be made to play a moive clip such as "staged_kiss_mc" only once?
The playhead on the main timeline rests in this single frame for a while; it would be great if "staged_kiss_mc" were to only play once, when the playhead first enters this frame, rather than apparently repeating continually...is there code to stop this repetition?

I have added a new tutorial on the EnterFrame event in ActionScript 3. This tutorial is almost 40 minutes in length and goes into the syntax of using the EnterFrame event and as an added feature there is a discussion on adding filters to a Sprite in
ActionScript 3.
I have also completed the polling system on the website. There are now three active polls asking the users of the site for their opinions on the tutorials, the website itself and what they would like to see developed in the way of future tutorials. Users can vote more than once, but I am tracking the user IP so that when it comes time to slice the data I can gather accurate information. Just thought I would announce that up front.
The next group of tutorials under development will be the conditional statements used in ActionScript. The IF, ELSE IF and SWITCH statements. I am looking forward to those tutorials as we can now start making the tutorials much more interesting putting
all we have learned together.

I have two buttons and a light blue circle. When you press the second button from the left, it changes the variable name to "boxTwo".In the circle video clip I have a enterframe with a condition to say, if the name is "boxTwo" play an animation, but it doesn't work.
Button:
Code:
on(release){
var name = "boxTwo";
_root[name].gotoAndStop(12);
trace(name);
}
On the circle MC that contains the animation
Code:
onClipEvent(enterFrame){
trace(_root.name);
if(_root.name == "boxTwo"){
circle.gotoAndPlay("loop");
}
}

I have a parent class that instantiates a MenuClass and handles transitions between pages.[code]And here's the MenuClass which creates forward and backward buttons. Clicking each will tell the above ParentClass to transitionForward() or transitionBackward() respectively.[code]One one hand, I feel like the MenuClass is too tightly bound to its parent and is thus less reusable. On the other hand I feel like, in the interest of keeping everything self contained, it's not the ParentClass's responsibility to reach into the MenuClass instance and add event listeners there. This seems like there should be some kind of OOP rule-of-thumb to govern this kind of relationship.Is my MenuClass too tightly bound to its parent? And if so, do you have any suggestions that would loosen that coupling?

How do you stop an ENTER_FRAME event after two tweens have executed?I have an AS3 package-based-classes Flash website loading nicely. The very last effect is the hover or active state for the button for the current page to tell the user what page they're on. I want the button's active state to execute using an ENTER_FRAME event and NOT using a Timer method. Mainly because I'd simply like to know how it's done and also because I've already used several timers to load the API. But, using the code below, I can't stop the ENTER_FRAME precisely after two tweens have fired - the Alpha tween and the Tweener that pulls the a blur effect into focus.[code]
I've tried several IF and ELSE IF conditions to tell Home.removeEventListener(Event. ENTER_ FRAME, OverState); exactly when to occur but the IF conditions either removeEventListener too soon, before the two tweens have fired, or the IF conditions just don't execute at all and the ENTER_FRAME trace continues on ad infinitum. You can use IF conditions that precisely operate on stage X and Y positions. But I can't figure out how to make an IF condition execute precisely after the two Tweens.How do you stop an ENTER_FRAME event PRECISELY after two tweens have executed so that Home.removeEventListener( Event.ENTER_ FRAME,OverState); executes at exactly the right point?

I've read that the enter keycode should be 13. However when using
trace(event.keyCode);
other keys will show up but the enter key does not. Could it be my computer or something? Using macbook pro keyboard.
stage.addEventListener(KeyboardEvent.KEY_DOWN, entered);
function entered(event:KeyboardEvent):void {
trace(event.keyCode);

i.e. I can't get this to trace "enter button" Also noticed no code traceable for Ctrl. alt Tab or Backpace

I frequently see the usage of ENTER_FRAME and EXIT_FRAME event types in AS3 code. I can even use the first event type just blindly to get certain things done. But I want to clear my concepts on these very fundamental things. My qeries are as below:When do the above 2 event types take place - I mean what triggers them?Does ENTER_FRAME trigger at the rate of FPS? If a MovieClip spans over 48 frames and the FPS = 24 - does this mean the ENTER_FRAME will occur 48 times for the full life-span of the MovieClip?Regarding the EXIT_FRAME, I could not find any example or description yet.

I'm having trouble getting the Video class to work.. Everything works fine until I try to add an on enter frame event listener to the movie. I basically want to overlay an effect that gets updated every frame but adding the event listener causes the movie to freeze before it loads or on the first frame or just shortly after starting play back.. Check out the source code at [URL]
It freezes even if the enter frame method body is commented out so I don't think it's because of extra overhead..
