要完成此效果把如下代码加入到<body>区域中
<span id="theText" style="width:100%">
<h2>JavaScript Fairyland</h2>
</span>
<script>
<!--
//range of glowing
var from = 5;
var to = 11;
//speed of pulsing
var delay = 55;
//color of glow, name or RGB value (example:’#00FF00’)
var glowColor = "lime";
//NO MORE EDITING!!!
var i = to;
var j = 0;
//can be called here or whenever you want the text to start pulsing
textPulseDown();
function textPulseUp()
{
if (!document.all)
return
if (i < to)
{
theText.style.filter = "Glow(Color=" + glowColor + ", Strength=" + i + ")";
i++;
theTimeout = setTimeout(’textPulseUp()’,delay);
return 0;
}
if (i = to)
{
theTimeout = setTimeout(’textPulseDown()’,delay);
return 0;
}
}
function textPulseDown()
{
if (!document.all)
return
if (i > from)
{
theText.style.filter = "Glow(Color=" + glowColor + ", Strength=" + i + ")";
i--;
theTimeout = setTimeout(’textPulseDown()’,delay);
return 0;
}
if (i = from)
{
theTimeout = setTimeout(’textPulseUp()’,delay);
return 0;
}
}
//-->
