MethodDescription
activeTimeToParentTime Converts a value in the element's active timeline to the corresponding point in the parent timeline.
activeTimeToSegmentTime Converts a value in the element's active timeline to the corresponding point in the segment timeline.
beginElement Starts the element on the timeline.

endElementAt Ends an element's timeline at the specified time.
nextTrack Advances the media-playing container to the next track, or playitem object, in the playlist collection, and begins playing that track.
parentTimeToActiveTime Converts a value in the parent timeline to the corresponding point in the element's active timeline.
parentTimeToDocumentTime Converts a value in the element's parent timeline to the corresponding point in the document timeline.
pauseElement Stops playing an element's timeline at the current point.
prevTrack Sets the media-playing container to the previous track, or playItem object, in the playList collection and begins playing that track.
resetElement Removes any changes made to the element and returns the element to its original state.
resumeElement Restarts the element's timeline from a paused state.
seekActiveTime Locates a specified point on the element's active timeline and begins playing from that point.
seekSegmentTime Locates the specified point on the element's segment timeline, and begins playing from that point.
seekTo Locates a specified point on the element's segment timeline, including repetitions, and begins playing from that point.
seekToFrame Locates a specified frame in the object.
segmentTimeToActiveTime Converts a value in the element's segment timeline to the corresponding point in the element's active timeline.
segmentTimeToSimpleTime Converts a value in the element's segment timeline to the corresponding point in the element's simple timeline.
simpleTimeToSegmentTime Converts a value in the element's simple timeline to the corresponding point in the element's segment timeline.
ObjectDescription
currTimeState Contains information about an HTML+TIME timeline.

Remarks

All HTML descendants of this element either have independent or parallel timing.

Use this element instead of the timecontainer attribute to create a time container without using an html element. all descendant elements, or time children, of this new time container inherit the time properties of their container. unlike the time children of the t:seq element, the par descendants have no implicit timing relationships with each other, and their timelines might overlap. the t:par element effectively groups elements together so they can be easily modified as a single unit.

the default value of begin for children of a par time container is 0 seconds.

the prefix t: is used to associate this element with an extensible markup language (xml) namespace. you must declare the xml namespace in the html tag of your document when using this element.

<html xmlns:t ="urn:schemas-microsoft-com:time">

you must then import the tag definitions from the time2 behavior by using the import processing instruction.

<?import namespace="t" implementation="#default#time2">

the members listed in the following table might not be accessible through scripting until the window.onload event fires. waiting for this event to fire ensures that the page is completely loaded, that all behaviors have been applied to corresponding elements on the page, and that all the behavior's properties, methods, and events are available for scripting. using any of the behavior-defined members before the window.onload event fires could result in a scripting error, indicating that the object does not support that particular member.

this element is not rendered.

this element requires a closing tag.

DHTML代码范例

This example uses the t:PAR element to apply a timeline to a group of HTML elements.

<HTML XMLNS:t ="urn:schemas-microsoft-com:time">
<HEAD>
<TITLE>PAR</TITLE>
<STYLE>
.time {behavior:url(#default#time2);}
</STYLE>
<?IMPORT namespace="t" implementation="#default#time2">
</HEAD>
<BODY TOPMARGIN=0 LEFTMARGIN=0 BGPROPERTIES="FIXED" BGCOLOR="#FFFFFF"
LINK="#000000" VLINK="#808080" ALINK="#000000">
<t:PAR BEGIN="0" DUR="10" TIMEACTION="display">
<H3>Paragraph 1</H3>
<P>This is paragraph number one. It appears for ten seconds immediately
after the page is loaded.</P>
<SPAN CLASS="time" BEGIN="5">
<H3>Paragraph 2</H3>
<P>This is paragraph number two. It appears five seconds after the
page is loaded, and remains displayed until its parent element's
timeline ends at ten seconds.</P>
</SPAN>
</t:PAR>
</BODY>
