闪烁的霓虹灯

下面框中为脚本显示区

脚本说明：
第一步:把如下代码加入<body>区域中:
 <SCRIPT LANGUAGE="JavaScript">

<!--

// create row of radio buttons
lay(20)

// set index of lamp to start animation
var current = 0

// set speed (pause in milliseconds between each movement)
var speed = 1000

function lay(num) {
        // assign "greater than" character to variable
        var gt = unescape("%3e")

// open form
        document.write("<FORM NAME='animation'" + gt)

// use loop to lay radio buttons down (all buttons in same group)
        for (var i = 0; i < num; ++i) {
                document.write("<INPUT TYPE='radio' NAME='lamps'" + gt)
        }

// close form
        document.write("</FORM" + gt)
}

function animate() {
        // click next radio button
        document.animation.lamps[current].click()

// if radio button is the last one reset variable to 0 (otherwise increment)
        current = (current == document.animation.lamps.length - 1) ? 0 : ++current

// recursive call after speed milliseconds
        timerID = setTimeout("animate()", speed)
}

// -->

</SCRIPT>

第二步:把<body>中的内容改为
<body bgcolor="#fef4d9" onLoad="animate()">
