t:PAR Element | par Object
This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.
Defines a new timeline container in an HTML document for independently timed elements.
Members Table
The following table lists the members exposed by the par object.
Attribute Property Description ACCELERATE accelerate Sets or gets a value that applies an acceleration to an element timeline.
AUTOREVERSE autoReverse Sets or gets whether the timeline on an element begins playing in reverse immediately after it completes in the forward direction.
DECELERATE decelerate Sets or gets a value that applies a deceleration to the end of a simple duration.
DUR dur Sets or gets a value indicating the amount of time the element remains active or displayed.
ENDSYNC endSync Sets or gets the synchronization rule that specifies which child element is used to determine when the time container ends.
FILL fill Sets or gets the action taken by an element if the element timeline ends before the timeline on its parent element ends.
mediaDur Gets the duration of the element's media file.
mediaHeight Gets the height of the element.
mediaWidth Gets the width of the element.
MUTE mute Sets or gets a value that indicates whether the audio is turned on or off.
REPEATCOUNT repeatCount Sets or gets the number of times an element timeline repeats. REPEATDUR repeatDur 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.
VOLUME volume 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.
timeAll 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>
