Sets or gets the number of seconds that an element timeline repeats.

Sets or gets the number of seconds that an element timeline repeats.
RESTART restart

Sets or gets the conditions under which an element can be restarted on a timeline.

SPEED speed

Sets or gets the playback speed of an element relative to its parent time container.

SYNCBEHAVIOR syncBehavior

Sets or gets a value that indicates the synchronization rules for the element timeline.

syncTolerance

Sets or gets the time variance that is allowed on a timeline with locked synchronization.

TIMEACTION timeAction

Sets or gets the action that is taken on the element while the timeline is active.

timeParent

Gets the parent time container element of the current element.

Sets or gets the volume of the media file.

Collection Description
activeElements

Returns a reference to the collection of all top-level child elements of the object that are currently active on the timeline.

Retrieves a reference to the collection of all timed elements.

timeChildren

Retrieves a reference to the collection of all timed, top-level children elements.

Event Property Description
onbegin

Fires when the timeline starts on an element.

onend

Fires when the timeline stops on an element.

onmediacomplete

Fires when the element's associated media finish loading.

Fires when the element's associated media finish loading.
onmediaerror

Fires when an element's media file causes any error.

onoutofsync

Fires when the element loses synchronization with its associated timeline.

onpause

Fires when the timeline on an element pauses.

onrepeat

Fires when the timeline repeats on an element, beginning with the second iteration.

onreset

Fires when the timeline reaches the value of the BEGIN attribute or when the resetElement method is called on the element.

onresume

Fires when an element's timeline resumes from a paused state.

onreverse

Fires when the timeline on an element begins to play backward.

onseek

Fires whenever a seek operation is performed on the element.

onsyncrestored

Fires when synchronization is resumed between the element and its associated timeline.

Method Description
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.

beginElementAt

Starts an element's timeline at the specified time.

documentTimeToParentTime

Converts a value in the document timeline to the corresponding point in the element's parent timeline.

endElement

Stops the element on the timeline.

endElementAt

Ends an element's timeline at the specified time.

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.

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.

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.

Object Description
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 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 document is completely loaded, that all behaviors have been applied to corresponding elements on the document , 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.

Example

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>
</HTML>
