onOffBehavior Property (deprecated)

  • Άρθρο

This page documents a feature of HTML+TIME 1.0, which was released in Microsoft® Internet Explorer 5. We recommend that you migrate your content to the latest version of HTML+TIME, which implements the SMIL 2.0 Working Draft. See the Introduction to HTML+TIME overview for more information.

This property is deprecated. Gets an object that indicates whether the specified Microsoft DirectAnimation behavior is running.

Syntax

HTML N/A
Scripting [ oOn = ] object.onOffBehavior

Possible Values

oOn A DirectAnimation Boolean (DABoolean) object that specifies one of the following values.
true
Behavior is running.
false
Behavior is not running.

The property is read-only. The property has no default value.

Remarks

This property is deprecated.

This property allows you to incorporate multimedia elements, such as 2-D and 3-D animated images and sounds, into an HTML page by using the anim:DA element. The object that this property is applied to must be an HTML object with a valid HTML+TIME (Timed Interactive Multimedia Extensions) timeline. Use this property with HTML+TIME timelines to control DirectAnimation content. This property is not part of the HTML+TIME specification.

Note  To ensure that pages using this property display properly in Windows Internet Explorer, complete the following steps.

  • Use #time instead of #default#time for the behavior declaration.
  • Include the time object in your page. The class identifier used to specify this object is 476C391C-3E0D-11D2-B948-00C04FA32195.

These actions are necessary only for pages that use HTML+TIME timelines to control DirectAnimation content.

Example

This example attaches a timeline specified with HTML+TIME to an image animated with DirectAnimation. The onOffBehavior property is used to display one image while the animation is running, and to display a different image while the animation is stopped.

<HTML>
<HEAD>
<TITLE>progressBehavior</TITLE>
<XML:NAMESPACE PREFIX="anim"/>
<STYLE>
.time       { behavior: url(#time); }
anim\:DA    { behavior: url(#default#anim); }
</STYLE>
<OBJECT ID="time" CLASSID="CLSID:476C391C-3E0D-11D2-B948-00C04FA32195">
</OBJECT>
</HEAD>

<BODY>
<P>An image of the sun is displayed before the DirectAnimation
behavior starts. Five seconds later, a new image replaces the
image of the sun. The new image fades out during five seconds
of animation, and the original image of the sun reappears.</P>

</DIV>

   // Create the DAImages
   img1 = m.ImportImage("/workshop/graphics/solarsys.gif");
   img2 = m.ImportImage("/workshop/graphics/sun.gif");
   // Display image 1 while the behavior is running, and
   // image 2 while it is stopped.
   img3 = m.Cond(spanImg.onOffBehavior, img1, img2)
   // Animate the opacity of the image from 100% to 0%, based on the
   // progress of the time behavior. Use (1 - progress) to get the
   // proper opacity.
   img4 = img3.OpacityAnim(m.Sub(m.DANumber(1),spanImg.progressBehavior));
   // Set the image of the DA Object to be the final image behavior
   da1.image = img4;
