About Content Selection: System Test Attributes and t:SWITCH

HTML+TIME 2.0 provides authors with the option to display different elements based on system settings.

Animating with keyTimes and keySplines

Using the keyTimes and keySplines attributes, you can divide an animation element's simple duration into multiple segments, speed up or slow down the animation at multiple rates during a single duration, and specify values for the animation to reach at particular points in its duration.

Getting Started with HTML+TIME

HTML+TIME (Timed Interactive Multimedia Extensions) makes it fast and easy to support timed, animated, and multimedia content on your pages.

Seeking With HTML+TIME

In HTML+TIME various types of media, animation, and other time elements can be played over a period of time. It is often desirable to be able to jump to any point on this time line. This process of jumping to different points on a time element's time line is called seeking.

Using HTML+TIME with DirectMusic

This article briefly discusses some of the ways you can use HTML+TIME to add flexibility and control to Microsoft?DirectMusic?content on the Web.

Using the HTML+TIME Document Object Model (DOM)

All HTML+TIME objects are accessible through script at run time. This article introduces you to the HTML+TIME objects, methods, events, and properties available to your Web pages.

Incorporate the time2 Behavior

This tutorial explains how to incorporate the time2 behavior in your Web pages so you can begin using timelines, multimedia, and animation with HTML elements.

Elements and Objects

currTimeState

Contains information about an HTML+TIME timeline.

switch

Enables you to provide several choices and display content depending on which choice is true on the user's computer.

Attributes and Properties

accelerate

Sets or retrieves a value that applies an acceleration to an element's timeline.

activeDur

Retrieves the total duration of the timeline.

activeTime

Retrieves the current point in time along the total active timeline, including repeats and time spent in reverse mode.

activeTrack

Sets or retrieves the track, or playItem object, that is currently active in the playList collection.

autoReverse

Sets or retrieves whether the timeline on an element begins playing in reverse immediately after completing in the forward direction.

begin

Sets or retrieves the delay time before the timeline begins playing on the element.

decelerate

Sets or retrieves a value that applies a deceleration to the end of a simple duration.

dur

Sets or retrieves a value indicating the amount of time the element remains active or displayed.

end

Sets or retrieves a value indicating the end time for the element, or the end of the simple duration when the element is set to repeat.

fill

Sets or retrieves the action an element takes if its timeline ends before the timeline on its parent element ends.

higher

Controls how elements with higher priority interrupt child elements of a priorityClass element.

isActive

Retrieves a value that indicates whether the element is currently active on the timeline.

isOn

Retrieves a value that specifies whether the element is active or holding on the timeline in its current state.

isPaused

Retrieves a value that specifies whether the element is paused on the timeline.

lower

Controls how elements that are defined with lower priority interrupt child elements of a priorityClass element.

parentTimeBegin

Retrieves the current element's begin time as an offset from the parent element's begin time.

parentTimeEnd

Retrieves the current element's end time as an offset from the parent element's begin time.

peers

Controls how child elements of a priorityClass element interrupt one another.

progress

Retrieves the current progress of the element's timeline.

repeatCount

Retrieves the current iteration in the repetition loop.

repeatCount

Sets or retrieves the number of times an element's timeline repeats.

repeatDur

Sets or retrieves the number of seconds that an element's timeline repeats.

restart

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

segmentDur

Retrieves the duration of an element on a timeline in seconds, including autoReverse.

segmentTime

Retrieves the current point in time along a segment of time.

simpleDur

Retrieves the duration of a repeat iteration.

simpleTime

Retrieves an object's current point along its timeline from zero to its dur value.

speed

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

speed

Retrieves the playback speed of an element at run time, which includes the cascading effect of the speed set for the parent time container.

state

Retrieves the current state of the element's timeline.

stateString

Retrieves the current state of the element's timeline.

syncBehavior

Sets or retrieves a value that indicates the synchronization rules for the element's timeline.

Sets or retrieves what action is taken on the element while the timeline is active.

timeContainer

Sets or retrieves the type of timeline associated with an element.

timeParent

Retrieves the parent time container element of the current element.

volume

Sets or retrieves the volume of the media file.

Methods

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.

seekTo

Locates a specified point on the element's segment timeline, including repetitions, and begins playing from that point.

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
