DHTML代码范例

This example sets the Strength and direction properties of the motionblur filter to an initial strength of 1. when the page loads, the strength and direction properties cause the onfilterchange event to fire repeatedly until the strength reaches 200.

<SCRIPT>
function HandleChange()
{
with (window.event.srcElement.filters[0])
{
if (strength < 200)
{
strength += 1;
direction += 45;
}
}
}</SCRIPT>
<IMG ID="img1" SRC="solarsys.gif" onfilterchange="HandleChange()"
STYLE="filter:progid:DXImageTransform.Microsoft.motionBlur(STRENGTH=1, DIRECTION=0)" />
