progressBehavior Property (deprecated)

  • Artikkeli

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.

Gets an object indicating the progress of the specified Microsoft DirectAnimation behavior.

Syntax

XML N/A
Scripting [ oProgress = ] time.progressBehavior

Possible Values

oProgress An Object that specifies the DirectAnimation number (DANumber class) used to indicate the progress of the behavior. The DANumber object contains a floating-point number with a value between 0.0 and 1.0, that indicates how much of the behavior is complete.

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 with 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 progressBehavior property is used to animate the opacity of the image.

<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>Two seconds after the page loads, the image begins to
fade. It disappears after five seconds of animation. This
process repeats itself three times.</P>
<SPAN ID="spanImg" CLASS="time" t:TIMEACTION="visibility" t:BEGIN="2"
t:DUR="5" t:REPEAT="3">
</SPAN>
<DIV ALIGN="center">
    <anim:DA ID="da1" STYLE="width:504; height:126; z-index: -1;" />
</DIV>
<BR>
<BUTTON onclick="spanImg.beginElement();">Restart</BUTTON>

<SCRIPT LANGUAGE="JScript">
<!--
   // Assign a variable to the DA statics library
   m = da1.statics;
   // Create a DAImage
   img1 = m.ImportImage("/workshop/graphics/solarsys.gif");
   // 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.
   img2 = img1.OpacityAnim(m.Sub(m.DANumber(1),spanImg.progressBehavior));
   // Set the image do be displayed
   da1.image = img2;
//-->
</SCRIPT>
</BODY>
