Docu~ ActionScript, Flash, javaScript

当Flash置于HTML容器中时，经常会遇到AS与JS的通信问题，例如：JS能否调用AS中的变量、方法，AS能否调用JS中的变量、方法等等。答案是肯定的。随着技术的不断发展，解决方案也是多种多样的。
在我总结的HTML与FLASH之间的“静态”传值一文中提到了JS使用SetVariable方法来设置FLASH中的变量，kinglong认为此法已经过时。对此我表示同意，但上文重点毕竟不是在讨论JS与AS的通信，因此另外对AS与JS通信做一个个人总结，欢迎大家讨论。
实现JS跟AS的通信，目前可选方法比较多，但早期的方法在使用便捷和功能上都不是很完美，下面做一简要说明：

在Flash8中:

方法一:

使用file.upload可以带参数给后台的ASP程序:

file.upload(_root.iisPath+”uploadFile.asp?userName=”+_root.userName+”&uploadName=”+_root.uploadName);

后台的uploadFile.asp:

<%
userName=request(”userName”)
uploadName=request(”uploadName”)
set upload=new upload_5xSoft ”建立上传对象
set file=upload.file(”Filedata”) ”生成一个文件对象
if file.FileSize>0 then ”如果 FileSize > 0 说明有文件数据
file.SaveAs Server.mappath(”.\”&userName&”\”&uploadName) ”保存文件
end if
set file=nothing
set upload=nothing ”删除此对象
%>

方法二:

不用file.upload方法,直接用LoadVars方法,简洁,好用.

FLA代码:

//上传代码
import flash.external.*;
browseBtn.onPress = function() {
_root.filePath = String(ExternalInterface.call(”getFilePath”, “Element”));
uploadTxt.text = _root.filePath;
};
uploadBtn.onPress = function() {
_root.getTime();
_root.uploadName += “.png”;
var myLoadVars:LoadVars = new LoadVars();
myLoadVars.load(_root.iisPath+”uploadFile.asp?userName=”+_root.userName+”&uploadName=”+_root.uploadName+”&filePath=”+_root.filePath);
myLoadVars.onData = function(data) {
uploadTxt.text = data;
};
};
在生成的html文件的head间插入:

在生成的html文件的body间插入:

后台的uploadFile.asp:

<%
userName= Request(”userName”)
uploadName= Request(”uploadName”)
filePath = Request(”filePath”)

Set objStream = Server.createObject(”ADODB.Stream”)
objStream.Type = 1 ” adTypeBinary
objStream.Open
objStream.LoadFromFile filePath
objStream.SaveToFile Server.MapPath(userName&”/”&uploadName)
Response.write(”上传完毕！”)
%>

在Flash9中:

方法一:

使用file.upload可以带参数给后台的ASP程序:

//获取上传文件名
parent.getTime()
var uploadURL:URLRequest;
var file:FileReference;
var fileType:String
uploadURL = new URLRequest();

//uploadURL.url = “http://127.0.0.1/upLoad/uploadFile.asp?userName=hdt&uploadName=1.jpg”
trace(parent.userName)
file = new FileReference();
file.addEventListener(Event.select, selectHandler);
file.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
file.addEventListener(ProgressEvent.PROGRESS, progressHandler);
file.addEventListener(Event.COMPLETE, completeHandler);
function selectHandler(event:Event):void {
var file:FileReference = FileReference(event.target);
//trace(”selectHandler: name=” + file.name + ” URL=” + uploadURL.url);
uploadTxt.text = file.name;
fileType = file.type;
}
function ioErrorHandler(event:IOErrorEvent):void {
//trace(”ioErrorHandler: ” + event);
uploadTxt.text =”上传失败…”
}
function progressHandler(event:ProgressEvent):void {
var file:FileReference = FileReference(event.target);
// trace(”progressHandler: name=” + file.name + ” bytesLoaded=” + event.bytesLoaded + ” bytesTotal=” + event.bytesTotal);
uploadTxt.text =”正在上传…”
}
function completeHandler(event:Event):void {
//trace(”completeHandler: ” + event);
uploadTxt.text =”上传完毕…”
}
browseBtn.addEventListener(MouseEvent.MOUSE_DOWN,browse);
function browse(e:Event){
var imagesFilter:FileFilter = new FileFilter(”Images”, “*.jpg;*.gif;*.png”);
var docFilter:FileFilter = new FileFilter(”Documents”, “*.pdf;*.doc;*.txt”);
file.browse([imagesFilter]);
}
uploadBtn.addEventListener(MouseEvent.MOUSE_DOWN,upload);
function upload(e:Event){

uploadURL.url = parent.iisPath+”/uploadFile.asp?userName=”+parent.userName+”&uploadName=”+parent.uploadName+fileType;
file.upload(uploadURL);
}

后台ASP文件同上

方法二:

不用file.upload方法,直接传文件名:

import flash.external.ExternalInterface;
var readyTimer:Timer = new Timer(100, 0);
var uploadURL:URLRequest;
browseBtn.addEventListener(MouseEvent.MOUSE_DOWN,browse);
function browse(e:Event){
if (checkJavaScriptReady()) {
filePath = String(ExternalInterface.call(”getFilePath”));
uploadTxt.text=filePath
} else {
readyTimer.addEventListener(TimerEvent.TIMER, timerHandler);
readyTimer.start();
}
}
uploadBtn.addEventListener(MouseEvent.MOUSE_DOWN,upload);
function upload(e:Event){
//开始上传
var loader:URLLoader = new URLLoader();
configureListeners(loader);
parent.getTime()
var fileType:String=filePath.split(”.”)[1]
parent.uploadName+=”.”+fileType
var uploadPath:String=parent.iisPath+”/uploadFileForJs.asp?userName=”+parent.userName+”&uploadName=”+parent.uploadName+”&filePath=”+filePath
uploadTxt.text=uploadPath
var request:URLRequest = new URLRequest(uploadPath);
try {
loader.load(request);
} catch (error:Error) {
uploadTxt.text=error
}
}
function checkJavaScriptReady():Boolean {
var isReady:Boolean = ExternalInterface.call(”isReady”);
return isReady;
}

function timerHandler(event:TimerEvent):void {
var isReady:Boolean = checkJavaScriptReady();
if (isReady) {
readyTimer.stop();
filePath = String(ExternalInterface.call(”getFilePath”));
uploadTxt.text=filePath
}
}
function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.COMPLETE, completeHandler);
dispatcher.addEventListener(Event.OPEN, openHandler);
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
}
function completeHandler(event:Event):void {
uploadTxt.text=”上传完毕…”
}
function openHandler(event:Event):void {
uploadTxt.text=”正在上传…”
}
function progressHandler(event:ProgressEvent):void {
trace(”progressHandler loaded:” + event.bytesLoaded + ” total: ” + event.bytesTotal);
uploadTxt.text=”已上传”+int((event.bytesLoaded/event.bytesTotal)*100)+”%”
}
function securityErrorHandler(event:SecurityErrorEvent):void {
uploadTxt.text=”IO错误…”
}
function httpStatusHandler(event:HTTPStatusEvent):void {
//uploadTxt.text=”HTTP状态…”
}
function ioErrorHandler(event:IOErrorEvent):void {
trace(”ioErrorHandler: ” + event);
uploadTxt.text=”"
}

后台ASP文件同上.

Docu~ Docu~, Flash

　前几天帮朋友做一个东西用到的 code 。
因为很久不做 Flash coding 了。所以也就很少关心 Flash 8 的新的 Calss。但听大家说过有这个功能。本想从网上找段教程或 code 来做。可是发现国内还没有类似的。就只能自己动手丰衣足食了。

开始做法：
第一步：在库中建立一个视频元件，类型选择：视频(受 ActionScript 控制)。
第二步：将视频元件拖到场景中，并调整尺寸到想要的大小。并起名为“my_video”
第三步：在时间轴中粘入下边的 code。
var my_video:Video;
my_video._x=100;
my_video._y=40;
var my_cam:Camera = Camera.get();
my_cam.setMode(180, 140, 10, true);
my_video.attachVideo(my_cam);

shutter.onRelease = function() {
myBitmap = new flash.display.BitmapData(180, 240, true, 0);
myBitmap.draw(my_video);
var tempObj = _root.createEmptyMovieClip(”photo”, 100);
tempObj._x = 300;
tempObj._y = 40;
tempObj.attachBitmap(myBitmap, 1, “always”, true);
};Testing 发现有问题，拍出来照片只有 160×120 的区域有图像。并且图像变形了。 什么地方出了问题呢？@#$%^&* (此处省略2小时 debug 时间……)
最后发现 my_video 复制到场景中调整大小时并不是改变 my_video.width 及 my_video.height 属性，而是改变 my_video._width 及 my_video._height 属性。原有视频元件的尺寸只有 160×120 。这就相当于将 my_video 作了形变。而 BitmapData.draw() 是不会考虑源元件的形变的。用官方的说法是：
引用: 源 MovieClip 对象不对此调用使用其任何舞台中转换。该源 MovieClip 对象会被视为存在于库或文件中，没有矩阵转换、没有颜色转换，也没有混合模式。如果您希望通过使用影片剪辑自身的 transform 属性来绘制影片剪辑，则可以使用它的 Transform 对象来传递各种 transformation 属性。
我开始没注意他给出的解决办法。我想既然 draw() 不考虑源元件的形变，那只能自己在输出的照片元件上想办法做形变了。于是有了这段 code。
var my_video:Video;
my_video._x=100;
my_video._y=40;
var my_cam:Camera = Camera.get();
my_cam.setMode(180, 140, 10, true);
my_video.attachVideo(my_cam);

shutter.onRelease = function() {
myBitmap = new flash.display.BitmapData(160, 120, true, 0);
myBitmap.draw(my_video);
var tempObj = _root.createEmptyMovieClip(”photo”, 100);
tempObj._x = 300;
tempObj._y = 40;
tempObj._width= 180;
tempObj._height = 240;
tempObj.attachBitmap(myBitmap, 1, “always”, true);
};这下照片是想要的大小了，而且图像也没有了变形。但发现图像没有摄像头显示的清晰。
想了一下，那是当然，draw() 不考虑源元件的形变，draw时my_video 被当作 160×120 来draw了。 那能不能通过改变 my_video.width 及 my_video.height 属性来改变 my_video 的尺寸而不是将 my_video 作形变呢？不能！！！my_video.width 及 my_video.height 属性是只读属性。

解决方法：
第一步：用视频编辑软件制作一个 180×240 尺寸的1贞的白色 mov 视频文件。
第二步：用 Macromedia Flash 8 Video Encoder 将mov视频文件转为 flv 视频文件。
第三步：在库中建立一个视频元件，类型选择：嵌入(与时间轴同步)。
第四步：将视频元件拖到场景中，并起名为“my_video”
Testing 发现 my_video.width 及 my_video.height 属性为 180×120 。阿哈 第五步：在时间轴中粘入下边的 code 。
var my_video:Video;
my_video.clear()
my_video._x=100;
my_video._y=40;
var my_cam:Camera = Camera.get();
my_cam.setMode(180, 140, 10, true);
my_video.attachVideo(my_cam);

shutter.onRelease = function() {
myBitmap = new flash.display.BitmapData(160, 120, true, 0);
myBitmap.draw(my_video);
var tempObj = _root.createEmptyMovieClip(”photo”, 100);
tempObj._x = 300;
tempObj._y = 40;
tempObj._width= 180;
tempObj._height = 240;
tempObj.attachBitmap(myBitmap, 1, “always”, true);
};好了，现在所有问题都解决了。

只要在

后面加入以下的 html代码
< noframes><meta HTTP-EQUIV=”refresh” CONTENT=”5; URL=你不含框架的索引页面(包含框架子页的链接)”>
这样搜索引擎会检索到你的框架子页 咯2`不用怕因为FLASH做导航 而使搜索引擎的蜘蛛无法检索到你的站内页面

在浏览器不支持FLASH或版本不够的时候 会显示文字导航,否则就显示FLASH导航
当然搜索引擎会检索你的文字导航

很简单就处理了

可以到一些国外的大型网站看看 他们的FLASH多数都是这么用的
详细使用方法 可以参看 《SWFObject: Javascript Flash Player detection》

Docu~ Docu~, Flash, ifarme, Seo

Using SWFObject is easy. Simply include the swfobject.js Javascript file, then use a small amount of Javascript on your page to embed your Flash movie. Here is an example showing the minimum amount of code needed to embed a Flash movie:
[code]

This text is replaced by the Flash movie.

[/code]

Here is a breakdown of what the code does:
[code]

[...]

[/code]

Prepare an HTML element that will hold our Flash movie. The content placed in the ‘holder’ element will be replaced by the Flash content, so users with the Flash plug-in installed will never see the content inside this element. This feature has the added bonus of letting search engines index your alternate content.
[code]
var so = new SWFObject(”movie.swf”, “mymovie”, “200″, “100″, “7″, “#336699″);[/code]

Create a new SWFObject and pass in the required parameters:

swf - The file path and name to your swf file.
id - The ID of your object or embed tag. The embed tag will also have this value set as it’s name attribute for files that take advantage of swliveconnect.
width - The width of your Flash movie.
height - The height of your Flash movie.
version - The required player version for your Flash content. This can be a string in the format of ‘majorVersion.minorVersion.revision’. An example would be: “6.0.65″. or you can just require the major version, such as “6″.
background color - This is the hex value of the background color of your Flash movie.

so.write(”flashcontent”);

Tell the SWFObject script to write the Flash content to the page (if the correct version of the plug-in is installed on the user’s system) by replacing the content inside the specified HTML element.

Passing variables into your movies using the “Flashvars” parameter:
