JavaScript :: Does ExternalInterface In Flex 3 Have Data Size Limitation?
Dec 7, 2009
I am using the ExternalInterface on Flex 3. We are actually using flex to compress a large amount of DOM data, so this is specifically being used with LARGE data. To further investigate, if there is a limitation, is this universal? (IE. Silverlight) First, let me state that this is being done with an application that was made by inexperienced software engineers. This is an app that we need to buy time by compressing the data so that we can build a long-term solution. We have no other options, unfortunately. Background: This is an application that is actually a web-spreadsheet. Our long term solution is to make a Office Business Application.
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:
public function callFromJavaScript():String { test.label='dfdsfsdf'; return "1"; } public function init():void {
[Code]...
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?)
We have several flash objects written in FLEX and being rendered inside a single HTML page.We are using javascript to communicate between the objects and perform other page related operations.
Execution Flow:
In the creationComplete event of the FLEX code of our objects we execute the following (pseudo-ish) code: if (ExternalInterface.available) { ExternalInterface.addCallBack("initialize"); ExternalInterface.callMethod("ready");
[code]....
Sometimes the last javascript function outlined is never called. When this happens none of the error alerts appear, the final code is just not executed but everything up to this point has executed successfully.
This happens about 1/100+ times in Chrome/Firefox
This happens about 1/10 times in IE8
This happens about 9/10 times in IE7 (full disclosure - the only machine we have to use for testing this is also much slower)
Since the problem is intermittent and becomes more apparent in slower browsers/machines my suspicion is that it is timing related. If I stop the first flex 'intiailize' call from happening until I click a button in the UI instead of automatically on what is essentially 'creationComplete' everything ALWAYS works.
I know there have been other questions on getting JavaScript / Flex ExternalInterface to play nicely, but I've what I think is a weird one. It works perfectly in every browser except Safari (on a Mac). Chrome, IE, Firefox - all ok, but Safari, nope it just wont fire.I've copied my code below, can anyone see why it doesn't work in Safari pls ?(the 'are you sure' dialog window appears in Safari but the method in the Flex app just doesn't get called)
From what Ive seen, most of the examples of using Javascript in Flex are designed for for the full desktop version (or for the browser) and not Flex mobile. For example using ExternalInterface in a Flex mobile project gives the error: Error: Error #2067: The ExternalInterface is not available in this container. ExternalInterface requires Internet Explorer ActiveX, Firefox, Mozilla 1.7.5 and greater, or other browsers that support NPRuntime. Is it possible to call Javascript (such as the Google Maps Javascript API) in a Flex mobile project?
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 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.
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.
how to get my dynamic textfield height and send it to a javascript to resize my embedded swf. I have been digging around for 2 days now and can't figure out how to do this. I've found lots of examples on sending text back and forth but not on how to send the height.
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.
I have this which is based off of this question: [URL]. However this neither works in firefox and IE. If I embed my flash into the browser like this: <embed src="helpdeskApp_three.swf" id="flash" quality="high" scale="exactfit" width="800" height="500" name="movie" align="middle" allowscriptaccess="always" type="application/x-shockwave-flash" pluginspage="[URL]"/>
This works in Firefox but not IE. What is the proper way of embedding my flash movie so it works across all browsers?
I have a swf that opens up inside a colorbox window. When the video finishes playing, I make an externalinterface call to a javascript function to close the colorbox.I'm trying to execute the following AS3 code:
I can't seem to get this to work. The colorbox won't close.I also tried this to see if I was just making the wrong function call, but this didn't work either: ExternalInterface.call ('alert("hello world")')However, if I browse to the url of the swf file, so that it doesn't open inside the colorbox, the alert() call works just fine.
I have a SWF file emedded withing a HTML page. Trying to do a simple operation - go to and play certain frame in SWF using javascript. I'm using ExternalInterface to do this but for the life of me can't get the two to communicate. I add all the code but when clicking on the link which calls javascript, it says my flash object is undefined?
Flash has the ExternalInterface class which can communicate to JavaScript running in the browser Can you use the ExternalInterface.available property to check if JavaScript is enabled?
