t:TIMEACTION Attribute | timeAction Property (deprecated)

  • Статья

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.

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

Syntax

XML <ELEMENT t:TIMEACTION = sAction... >
Scripting [ sAction = ] object.timeAction

Possible Values

sAction String that specifies or receives one of the following values.
class:classname1 [classname2 ...]
The specified classname is applied to the element while it is active on the timeline and removed while the element is inactive. The class value is available as of Microsoft Internet Explorer 5.5.
display
The element displays when the timeline is active and disappears when the timeline is inactive. As the element changes between active and inactive states, the surrounding HTML elements dynamically reflow within the page.
none
The element takes no action. This is useful for time grouping when the parent element should do nothing in response to timing. Media will still play when timeAction is set to none.
onOff
The element on property toggles between true and false over time. The onOff value is invalid if no on property exists for the element, which can produce unwanted results.
style
The element displays with the inline style when the timeline is active, and displays without the inline style when the timeline is inactive. If no inline style is defined for this element, nothing happens.
visibility
Default. The element visibility property displays the element when the timeline is active, and makes the element disappear when the timeline is inactive. The surrounding HTML elements do not reflow as a result of the local element changing between active and inactive states.

The property is read/write. The property has a default value of visibility.

Remarks

The default value of the timeAction property depends on the element that is using it. When this property is used on the body element, the default value is none. When it is used on the t:SEQ element, the default value is display. For all other elements, the default value is visibility.

If you specify a CLASS attribute for the timeAction property that is already present on the element, that class is removed whenever the element is not active on the timeline. In the following example, the redText class is applied only while the span is active on the timeline; however, the boldFont class is always applied to the span.

<SPAN CLASS="redText boldFont" STYLE="behavior:url(#default#time2)" 
    BEGIN="5" TIMEACTION="class:redText">The text is red 
    only while this element is active on the timeline.
</SPAN>

To specify multiple classes for the timeAction property, separate the class names with white space. If you specify an invalid class name, it is equivalent to a timeAction value of none.

When you use an element associated with the time behavior, you must prefix the attribute with the t: namespace.

Example

This example shows text with different timeAction values.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD W3 HTML//EN">
<HTML>
<HEAD>
<STYLE>
  .time  { behavior: url(#default#time);}
</STYLE>
</HEAD>
<BODY BGCOLOR="white">
<SPAN CLASS="time" STYLE="Color:Red; Font-Weight:bold;" t:BEGIN="0"
    t:DUR="5" t:TIMEACTION="style">
    <H3>Paragraph 1</H3>
    <P>This is paragraph number one. It is displayed in red, bold
    typeface for five seconds. After five seconds, the inline style 
    is no longer applied. The timeAction property is set to
    "style."</P>
</SPAN>
<SPAN CLASS="time" STYLE="COLOR:Blue;" t:BEGIN="0" t:DUR="10" 
    t:TIMEACTION="display">
    <H3>Paragraph 2</H3>
    <P>This is paragraph number two. It displays for 10 
    seconds. The timeAction property is set to "display."</P>
</SPAN>
<SPAN>
    <H3>Paragraph 3</H3>
    <P>This is paragraph number three. When the second
    paragraph disappears, this paragraph moves into its place because 
    the document reflows.</P>
</SPAN>
</BODY>
</HTML>
