Javascript :: AS3 ExternalInterface: Control A Movie From Another Window?
Dec 10, 2010
How can I control a flash movie in a window from a child (pop-up) window invoked via ExternalInterface's call method?
The name of the movie is myMovie. Using javascript in the popup, I try to access a function in the movie using document['myMovie'].flashFunction(). However, since the javascript is in the popup window and the flash is in another, the browser complains that the function is undefined.
This would have worked if the javascript and the movie were in the same window.
I'm working on a site that allows administrators to upload arbitrary SWFs and embed them on the page. Administrators are in theory trusted, but I still want to protect against potentially malicious administrators or misguided administrators from harming the site.
A part of the functionality of the site is that the SWFs can communicate to the containing browser page when it's finished and for the page to react.
Now, I can think of two ways to do this:
Use ExternalInterface.addCallback to create a global callback named something like isComplete that does logic and returns true or false depending on whether the Flash app is in a completed state. Then, just do something like setTimeout to just call that function repeatedly. I don't think this would require me to open up allowscriptaccess to the movie. Embed the movie with allowscriptaccess and have the movie call something like ExternalInterface.call('done') when it's finished. This option seems like it requires me to open up allowscriptaccess, which is a potential threat since I can't control the SWFs that would be embedded with this directive.
I can open a new window using window.open() in ExternalInterface.call() but then I want to be able to write contents to the new window. Since, I cannot get the reference of the window back from window.open() call, I am not able to do anything to the window once it is opened.
I do not have any control over the HTML in which my swf is displayed.
Has anyone been in this situation before?
Update: After a few hours of trial and error I found you can get out of this situation by storing your window reference globally and referring to the same global reference whenever you need to access the new window.
I'm trying to control a Flash video player with external Javascript commands using 'ExternalInterface.addCallback' but I'm not having any success. Here is the HTML code:
On my page, I'm going to embed multiple Flash files that use ExternalInterface to communicate back to the page. When the page receives the ExternalInterface calls, is there any built-in way to determine which swf the call came from?
I don't mind giving each movie a guid FlashVar and attaching that to each ExternalInterface call, but I don't want to duplicate more tested functionality.
I get the alert but I can't get the lightbox window to display. When my as code makes the ExternalInterface call I get what looks like a page refresh and a blank browser window.
Is it possible to control a Flash movie from JS when you have no control over the source? I have decompiled the movie to see its inner workings, but I know nothing about Flash, so I'm mostly in the dark. I found this resource, Interaction with JavaScript, but it's not working for me (probably because I don't know what message to send to the movie).
I have a flash movie with an audio clip in it. I simply want to embed the movie in my page and when a user clicks a link in the HTML, it tells the flash movie to play. The onclick would trigger a JS function that would play the flash movie. Is this possible?
I've been attempting to launch a window from an attached movie, I've got the function to work but after it launches, the main window (with the flash file) relocates automatically with the message "[object Window]"
I'm presently using the following coding with the button's AS:
i am creating a website for a band, with an mp3 player. i want to be able to make an mp3 player that pops up in a separate browser window. the mp3 player would have a "playlist" that can be dynamically changed from the main window, which gives a list of albums & tracks to choose from. the model for this is Rhapsody's web interface. so, how would i go about creating & dynamically changing the playlist (while music is playing) across multiple browser windows? the "playlist" would be an array of references to mp3s, i guess-- so is there a way to pass events & variables across the windows?
I am trying to use the ExternalInterface.call function in my ActionScript(2.0) to get a javascript var value set in the wrapping document. The following seems to work in FireFox and in Chrome but, naturally, it does not work in IE(8). getting the value stored at this variable?
var linkPath = ExternalInterface.call("function(){return window.customLinkLocation;}", null);
I am having problems with External interface and IE9. The swf objects play fine but none of the information input is transferred to the cookies that should be set. I have seen that there are other questions similar to this but have not been able to solve my problem using them. THis is the html we are using
AdobeTV showed a way to allow Flash to "talk" to an HTML page via javascript using the ExternalInterface method. There seems to be a catch. You need to use the ID of the swf in the parameters to have it all fit together and you can only put the ID="swf" into the IE section of the Dreamweaver generated javascript or into the non-IE section. Putting it in both didn't work and the author mentioned only putting in one of them specifically.Is there a way to do this that would work in both sets of generated Javascript?
I'm looking to call a flash method from a method in javascript and recieve a result:Example:Flash -
ExternalInterface.addCallback("getProgress", getProgress) // Javascript to flash public function getProgress():void { ExternalInterface.call("getProgress", progress); // Send progress back to javascript from
I have a simple html doc with a flex app and an iframe side-by-side (using a 1x2 table).There is a button in the flex app that, when clicked, sets the "src" property of the iframe to a URL by using the ExnternalInterface.call method to call a javascript function "doNavClick(url)".Or that's the idea.When I comment out the iframe object declaration in the html, the call to doNavClick works (I pop up an alert to test)....yet when the iframe declaration is present, it doesn't even receive the call. It's as if the iframe has somehow broken the call dispatching mechanism.Is there a workaraound for this?The problematic code is as follows:
I have an issue with my ExternalInterface. The way it is currently set up is, on the page load up, a boolean is set to true in JavaScript and then checked by ActionScript constructors (using a timer) until it is true. This marks that JavaScript is ready to get calls from AS3.
At this point, AS3 will add the callback and do some internal stuff, and at the end of the constructor I call JavaScript. So far so good. JavaScript will at this point call a function in AS3 (that was defined in the callback described above), and this is where it all messes up.
On IE this works perfectly fine. On FireFox though, it does not. When I debug it, I see that the javascript function is called but when it tries to call AS3, nothing happens. I also tried to add a timer, but for some reason the function STILL executes straight away (in IE).
None of the similar answered questions fixed my problem, so here it goes. I want to call actionscript 3 function from JavaScript but in FF error console it says that the function I'm calling from JS does not exist. It says functions mover and mout are not defined. Here is the JS functions in JS file
I am having a problem with Internet Explorer and various lightbox programs (PrettyPhoto, TopUp, and Bumpbox). Essentially I want to make a call using Flash's ExternalInterface class from a swf that has been loaded into a lightbox. It works in firefox but not in IE (8). Here is my working example using PrettyPhoto and here is my working example using TopUp. When the exact same swf is embedded in the top of the page the ExternalInterface call works fine (you can click it on that page). But when the swf is opened in the lightbox by clicking the image it will not work in IE.
I want to call a function inside a Flash movie from javascript, using the ExternalInterface class. The problem is that to get it to work with Firefox I need to use the embed element and with the rest I have to get the object element. To solve it, I gave different ids to that two elements and depending on the user agent I select one or the other:
function getMovie(movieName) { alert(navigator.userAgent); if (navigator.userAgent.indexOf("Firefox") != -1) {
[Code].....
This works, but it is not very elegant and it may not work with other browsers..
I am calling an Actionscript function from JavaScript and it works in all browsers except for IE9. I narrowed it down to the js function that retrieves the movie object:
I'm trying to call a function declared with ExternalInterface in a Flash swf, using JavaScript.It worked once, but all of a sudden, it stopped working.I have a debug version of the Flash Player, but no errors occur in Flash.Not even a "Security Sandbox Error" or something. The only error I get is the following error in JavaScript Error: Error in Actionscript. Use a try/catch block to find error.I'm using AS3, exporting for Flash Player 10 and testing on Firefox 3/Safari 4, on a Mac.
I'm trying to call a function in my ActionScript from my JavaScript, I've managed to successfully do this with another flash file but in the current one it's failing for some reason. I'm using jQuery SWFEmbed, this is my JS code:[code]The ExternalInterface.call work, and the trace outputs true, I have no idea what's going on.If you could also tell me how I can pass parameters to a ExternalInterface callback.
public function callFromJavaScript():String { test.label='dfdsfsdf'; return "1"; } public function init():void {

I have no clue wich one are crossbrowser compatible (cant install IE to test out)I have tried multiple but i cant get them to work(in any browser), im probably using the wrong id, ive been trial & erroring for a couple of hours but i don't have anything working.(i heard there was a problem with ExternalInterface.addCallback on a local file system?, should i upload the swf? < is the flex code right& problem = javascript/html side?)
I have a chat application that I built using Flex. The application on page load is hidden by setting the <object> in the page height to 0px. I did this because I need to be able to talk to the swf with javascript and setting the object to hidden really does "hide" it. In other words it treats the swf like it is not loaded on the page at all.I have an HTML button on the page that says "chat". When you click the button a couple of things happen. First I show the swf by setting the <object> height to 330px and I also tell the swf what person I am going to be chatting with by passing in a user name variable using javascript.On Windows using FF and IE my javascript can't find the swfobject.getObjectById("myswf") if the <object> height is set to 0px. Sometimes it can't find the swf at all event if height is set to 300px.The javascript calls work perfectly on OS X in any browser and it works on windows using Safari.
i'm currently trying to call a javascript function and pass values to it. but i'm not really familiar in using the addcallback since i only tested on calling a function from flash without passing anything to the function.
Basically, i'm going to retrieve the values of a node from xml. and then i will assign those values to a variable in flash. now what i'm going to do next is pass this value to a javascript parameter..is it done using externalinterface?
I just need to throw the value to the javascript function parameter and no return values to the actionscript. The event is that whenever an image is click, the corresponding value for each image is passed to the javascript function.
Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song.
I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not?
I'm trying to call a method inside a flash movie from js, every time the mouse leaves the "div". It works on Internet Explorer, but not in firefox. Here is the html script:
Here is example of the problem, there is an alert for the js and the flash should be able to remove the swf (see a gray background? it works! see a image, flash didn't receive the call): [URL]. This should work with internet explorer / safari / chrome (pc/mac) only firefox seams to reject this.
