***页面背景***按钮驱动背景
把下列代码加到网页的<body></body>标签之间 从google下载我的照片管理软件脚本说明:
第一步:把如下代码加入<head>区域中
<script language="javascript">
<!--
function backcolor(form){
temp = ""
for (var i = 0; i < 16; i++) {
temp = form.color.value
if (form.color.checked){ document.bgcolor = temp }
}
}
function randombackground(){
document.bgcolor = getcolor()
}
function getcolor(){
currentdate = new date()
backgroundcolor = currentdate.getseconds()
if (backgroundcolor > 44)
backgroundcolor = backgroundcolor - 45
else if (backgroundcolor > 29)
backgroundcolor = backgroundcolor - 30
else if (backgroundcolor > 15)
backgroundcolor = backgroundcolor - 16
if (backgroundcolor == 0 )
return "olive";
else if (backgroundcolor == 1 )
return "teal";
else if (backgroundcolor == 2 )
return "red";
else if (backgroundcolor == 3 )
return "blue";
else if (backgroundcolor == 4 )
return "maroon";
else if (backgroundcolor == 5 )
return "navy";
else if (backgroundcolor == 6 )
return "lime";
else if (backgroundcolor == 7 )
return "fuschia";
else if (backgroundcolor == 8 )
return "green";
else if (backgroundcolor == 9 )
return "purple";
else if (backgroundcolor == 10 )
return "gray";
else if (backgroundcolor == 11 )
return "yellow";
else if (backgroundcolor == 12 )
return "aqua";
else if (backgroundcolor == 13 )
return "black";
else if (backgroundcolor == 14 )
return "white";
else if (backgroundcolor == 15 )
return "silver";
}
// -->
</script>
第二步:把如下代码加入<body>区域中
<form>
<input type="button" value="random" onclick="randombackground()">
