Add Flash to Web Pages
‣ Deliver FlashHTML pages by embedding
SWF ﬁles in
to your users

‣ Allows you to control the size and
display preferences
‣ Several ways to do this:
‣ Add static embed code to your HTML
pages
‣ Use Adobe Flash to "publish" the code
‣ Use a dynamic method with JavaScript

Two Ways to Add Static
Embed Code

Embed tag
<embed type="application/x-shockwave-flash"
src="myContent.swf" width="300" height="120"
pluginspage="http://www.adobe.com/go/getflashplayer" />
<noembed>Alternate content</noembed>

•Advantages
‣ Simple and clean
‣ Chosen for widespread use by Google Video,
YouTube, and others
•Disadvantages
‣ Does not validate aspart of the XHTML The
<embed> tag is not
XHTML compliant.
speciﬁcation.

Object tag
<object type="application/x-shockwave-flash"
data="myContent.swf" width="300" height="120">
<p>Alternate content</p>
</object>

Variation required by Internet Explorer:
<object classid="clsid:D27CDB6E-
AE6D-11cf-96B8-444553540000" width="300" height="120">
<param name="movie" value="myContent.swf" />
</object>

Object tag: Nested
• To get the object tag to work as one block of code in the two ways it
can written, nest them with IE conditional tags:

<object classid="clsid:D27CDB6E-
AE6D-11cf-96B8-444553540000"
width="300" height="120">
   <param name="movie" value="myContent.swf" />
   
     <object type="application/x-shockwave-flash"
     data="myContent.sw" width="300" height="120">
   
   
     </object>
   
</object>

Publishing with Adobe
Flash

Publish Settings

• File > Publish Settings…

appear when published from other
menus, including Test Movie
‣ Choose Format, Flash, and HTML
options
‣ Use version detection to load alternate
content
‣ File > Export... allows more flexibility
when creating Quicktime files

SWF Object

• http://code.google.com/p/swfobject/
‣ Offers more ﬂexibility and control in
delivering SWF ﬁles.
‣ Documentation:
http://code.google.com/p/swfobject/
wiki/documentation

SWFObject dynamic
publishing
• Between the <head> tags:
<script type="text/javascript”
src="swfobject.js"></script>

<script type="text/javascript”>
swfobject.embedSWF(
"myContent.swf", "myContent","300","120","9.0.0" );
</script>

• In your HTML <body>:
<div id="myContent”>
</div>

SWF Object Parameters
<script type="text/javascript”>
var flashvars = {
name1: "hello",
name2: "world",
name3: "foobar"
};
var params = {
menu: "false"
};
var attributes = {
id: "myDynamicContent",
name: "myDynamicContent"
};
swfobject.embedSWF("myContent.swf", "myContent”, "300",
"120", "9.0.0","expressInstall.swf",
flashvars, params, attributes);
</script>

Checking if the movie has
loaded
‣ Use the ﬁrst keyframe for
ActionScript that will check if the
movie has loaded.
‣ The preloader will play in the ﬁrst
keyframe until the movie has
loaded.

Preloader Script: First
Keyframe
stop();
this.addEventListener(Event.ENTER_FRAME,
loading);
function loading(e:Event):void {
   var total:Number =
this.stage.loaderInfo.bytesTotal;
   var loaded:Number =
this.stage.loaderInfo.bytesLoaded;
if (total == loaded) {
   play();
this.removeEventListener(Event.ENTER_FRAME, loading);
}
}

Percentage Bar Preloader
stop();
this.addEventListener(Event.ENTER_FRAME, loading);
function loading(e:Event):void{
var total:Number =
this.stage.loaderInfo.bytesTotal;
var loaded:Number =
this.stage.loaderInfo.bytesLoaded;
bar_mc.scaleX = loaded/total;
loader_txt.text = Math.floor((loaded/total)*100)+ "%”;
if (total == loaded){
play();
this.removeEventListener(Event.ENTER_FRAME,
loading);
}
}
