BEGIN Attribute | begin参数属性

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

What's New for Microsoft?Internet Explorer 6

The begin property applies to the transitionFilter element.

dhtml语法

HTML <ELEMENT BEGIN = sTime... >
Scripting object.begin [ = sTime ]

HTML	<ELEMENT BEGIN = sTime... >
Scripting	object.begin [ = sTime ]

DHTML可能的值

sTime String that specifies or receives one or more of the following values.
clock-value Clock value, such as h:min:s.f, described in time formats.
id.event[+clock-value] element begin time is defined relative to the firing of an event. the clock-value is optional.
indefinite element begin time is determined by a beginElement method call.
The property is read/write. The property has a default value of 0.

Remarks

The begin property exposed by the time2 behavior includes functionality that was previously provided by the beginAfter and beginWith properties in the time behavior.
The BEGIN attribute can be assigned many BEGIN time values. For example, to make the element begin 12 seconds after element x receives focus, specify BEGIN="x.onfocus+12s". To make the element begin 10 seconds before element x begins, specify BEGIN="x.end-10s". If you want an element to begin four seconds after the page loads or to begin one second after the user clicks an object on the page, use the following syntax. BEGIN="4; oObject.click+1".
You can set the begin property relative to an event by using the syntax begin="element.onevent" and begin="element.event"; both are valid.
For children of excl time containers, the default value is indefinite.

Examples

This example uses the BEGIN attribute to make text appear and disappear over time.

<HTML>
<HEAD>
<STYLE>
.time{ behavior: url(#default#time2);}
</STYLE>
</HEAD>
<BODY BGCOLOR="white">
<SPAN CLASS=time STYLE="COLOR:Red;" BEGIN="0" DUR="3"
TIMEACTION="display">
<H3>Paragraph #1</H3>
<P>This is paragraph number one. It appears for three seconds immediately
after the page is loaded.</P>
</SPAN>
<SPAN CLASS=time STYLE="COLOR:Blue;" BEGIN="4" DUR="4"
TIMEACTION="display">
<H3>Paragraph 2</H3>
<P>This is paragraph number two. It appears one second after the first
paragraph disappears, and remains displayed for four seconds.</P>
</SPAN>
<H1 CLASS=time BEGIN="8" DUR="indefinite" TIMEACTION="display">
The End.
</H1>
</BODY>

<P>Click the following button to display a paragraph two seconds later.

<BUTTON ID="button1">Show Paragraph</BUTTON><BR><BR>
<SPAN ID="span1" CLASS=time STYLE="COLOR:Red;"
BEGIN="button1.click+2" DUR="5" TIMEACTION="display">
<H3>Paragraph 1</H3>
<P>This is paragraph number one. It appears two seconds after
the button is clicked and displays for five seconds.</P>
