Remarks

All timed HTML descendants of this XML element have sequential timing. A duration value (dur property) must be specified or the next element in the sequence might never be displayed. elements without timing attributes are ignored by the timing mechanism and are statically rendered. a timed element is an html element with an associated time behavior.

the prefix t is used to associate this element with an xml namespace. you must include the following line of code in the head section of your HTML document when using this element.

<XML:NAMESPACE PREFIX="t"/>

The t:SEQ element is available as of Microsoft?Internet Explorer 5, only in the Microsoft?Win32?platform.

DHTML代码范例

This example uses the t:SEQ element to display a sequence of text lines without specifying begin times for each timed element in the sequence.

<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<HTML>
<HEAD>
<XML:NAMESPACE PREFIX="t"/>
<STYLE>
.time    {behavior: url(#default#time);}
</STYLE>
</HEAD>
<BODY BGCOLOR="white">
<t:SEQ ID="parent" CLASS="time" t:BEGIN="0" t:DUR="indefinite">
<DIV ID="div1" CLASS="time" t:DUR="2">First line of text.</DIV>
<DIV ID="div1" CLASS="time" t:DUR="2">Second line of text.</DIV>
<DIV ID="div1" CLASS="time" t:DUR="2">Third line of text.</DIV>
<DIV ID="div1" CLASS="time" t:DUR="2">Fourth line of text.</DIV>
<SPAN STYLE="color:black" ID="span1" CLASS="time"
t:DUR="indefinite"><B>End of sequence.</B></SPAN>
</t:SEQ>
</BODY>
