74、状态栏特效

脚本说明:

第一步:把如下代码加入<body>区域中:

<script language="JavaScript">

<!--

var speed = 10

var pause = 2000

var timerID = null

var bannerRunning = false

var ar = new Array()

ar[0] = " "

ar[1] = " "

ar[2] = " "

ar[3] = " "

var message = 0

var state = ""

clearState()

function stopBanner()

{

if (bannerRunning)

clearTimeout(timerID)

bannerRunning = false

}

function startBanner()

{

stopBanner()

showBanner()

}

function clearState()

{

state = ""

for (var i = 0; i < ar[message].length; ++i)

{

state += "0"

}

}

function showBanner()

{

if (getString())

{

message++

if (ar.length <= message)

message = 0

clearState()

timerID = setTimeout("showBanner()", pause)

bannerRunning = true

}

else

{

var str = ""

for (var j = 0; j < state.length; ++j)

{

str += (state.charAt(j) == "1") ? ar[message].charAt(j) : ""

}

window.status = str

timerID = setTimeout("showBanner()", speed)

bannerRunning = true

}

}

function getString()

{

var full = true

for (var j = 0; j < state.length; ++j)

{

if (state.charAt(j) == 0)

full = false

}

if (full)

return true

while (1)

{

var num = getRandom(ar[message].length)

if (state.charAt(num) == "0")

break

}

state = state.substring(0, num) + "1" + state.substring(num + 1, state.length)

return false

}

function getRandom(max)

{

return Math.round((max - 1) * Math.random())

}

// -->

</script>

 

 

第二步:把<body>区域中的内容改为

<body bgcolor="#fef4d9" onload="startBanner()">
