组织办活动，到了抽题答题的环节我想用这么一个转盘选题，总比拿箱子放纸条要高端大气多了
找个差不多的自己改一下P点图片就OK了其实，有什么更好的方案么
第一种是JS+HTML的：
[mw_shl_code=javascript,true]<!DOCTYPE HTML>
*本站禁止HTML标签噢*
*本站禁止HTML标签噢*
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
*本站禁止HTML标签噢* flash抽奖转盘通用模板</title>
<style type="text/css">
#flashContent { width:510px; height:510px; }
#layer { background:#f5f5f5; border:#000 solid 1px; padding:20px; position:absolute; left:50%; top:50%; display:none; }
</style>
</head>
*本站禁止HTML标签噢*
<div id="flashContent"></div>
*本站禁止HTML标签噢*
flashHoler = "flashContent" //加载flash的容器ID
autoPlay = "yes" //初始化时是否自动旋转，"yes" or "no"
setPointer="no" //初始化时是否设置鼠标指针，"yes" or "no"
url_bg = "bg.png"; //转盘背景图片
url_prize = "prize.png"; //奖品图片
url_pointer = "pointer.png"; //指针图片
url_btnStart = "btnStart.swf"; //开始按钮图片，可以是图片或flash
url_btnOver = "btnOver.gif"; //鼠标经过图片
url_btnWait = "btnWait.gif"; //旋转过程中按钮图片
url_btnSuc = "btnSuc.gif"; //旋转结束后按钮图片
W_bg = "510"; //背景图片尺寸
W_btn = "124"; //按钮图片尺寸
W_pointer = "150"; //指针图片宽度
H_pointer = "255"; //指针图片高度
totleNum = 10; //奖品个数
turns = 10; //旋转圈数
stopNum = Math.floor(Math.random()*10)+1; //中奖奖品
</script>
<script src="loadFlash.js"></script>
<script src="jquery-1.7.min.js"></script>
</body>
</html>[/mw_shl_code]
上面中奖奖品的地方是我自己改了个随机数，附件里面的demo3.html是这个
第二种是HTML5的：
图片看起来很渣对吧，页面没有用图片，就一个HTML，这个圈全是canvas里面画出来的，转的很平稳，最后还是慢慢停下的
[mw_shl_code=javascript,true]<input type="button" value="开始旋转" style="float: left;" />
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<canvas id="wheelcanvas" width="500" height="500"></canvas>
<script type="application/javascript">
var colors = ["#B8D430", "#3AB745", "#029990", "#3501CB",
"#2E2C75", "#673A7E", "#CC0071", "#F80120",
"#F35B20", "#FB9A00", "#FFCC00", "#FEF200"];
var restaraunts = ["北京", "上海", "天津", "南京",
"杭州", "深圳", "武汉", "济南",
"重庆", "大连", "合肥", "郑洲"];
var startAngle = 0;
var arc = Math.PI / 6;
var spinTimeout = null;
var spinArcStart = 10;
var spinTime = 0;
var spinTimeTotal = 0;
var ctx;
function draw() {
drawRouletteWheel();
}
function drawRouletteWheel() {
var canvas = document.getElementById("wheelcanvas");
if (canvas.getContext) {
var outsideRadius = 200;
var textRadius = 160;
var insideRadius = 125;
ctx = canvas.getContext("2d");
ctx.clearRect(0,0,500,500);
ctx.strokeStyle = "black";
ctx.lineWidth = 2;
ctx.font = 'bold 12px sans-serif';
for(var i = 0; i < 12; i++) {
var angle = startAngle + i * arc;
ctx.fillStyle = colors;
ctx.beginPath();
ctx.arc(250, 250, outsideRadius, angle, angle + arc, false);
ctx.arc(250, 250, insideRadius, angle + arc, angle, true);
ctx.stroke();
ctx.fill();
ctx.save();
ctx.shadowOffsetX = -1;
ctx.shadowOffsetY = -1;
ctx.shadowBlur = 0;
ctx.shadowColor = "rgb(220,220,220)";
ctx.fillStyle = "black";
ctx.translate(250 + Math.cos(angle + arc / 2) * textRadius, 250 + Math.sin(angle + arc / 2) * textRadius);
ctx.rotate(angle + arc / 2 + Math.PI / 2);
var text = restaraunts;
ctx.fillText(text, -ctx.measureText(text).width / 2, 0);
ctx.restore();
}
//Arrow
ctx.fillStyle = "black";
ctx.beginPath();
ctx.moveTo(250 - 4, 250 - (outsideRadius + 5));

ctx.lineTo(250 + 0, 250 - (outsideRadius - 13));
ctx.lineTo(250 - 9, 250 - (outsideRadius - 5));
ctx.lineTo(250 - 4, 250 - (outsideRadius - 5));
ctx.lineTo(250 - 4, 250 - (outsideRadius + 5));
ctx.fill();
}
}
function spin() {
spinAngleStart = Math.random() * 10 + 10;
spinTime = 0;
spinTimeTotal = Math.random() * 3 + 4 * 1000;
rotateWheel();
}
function rotateWheel() {
spinTime += 30;
if(spinTime >= spinTimeTotal) {
stopRotateWheel();
return;
}
var spinAngle = spinAngleStart - easeOut(spinTime, 0, spinAngleStart, spinTimeTotal);
startAngle += (spinAngle * Math.PI / 180);
drawRouletteWheel();
spinTimeout = setTimeout('rotateWheel()', 30);
}
function stopRotateWheel() {
clearTimeout(spinTimeout);
var degrees = startAngle * 180 / Math.PI + 90;
var arcd = arc * 180 / Math.PI;
var index = Math.floor((360 - degrees % 360) / arcd);
ctx.save();
ctx.font = 'bold 30px sans-serif';
var text = restaraunts[index]
ctx.fillText(text, 250 - ctx.measureText(text).width / 2, 250 + 10);
ctx.restore();
}
function easeOut(t, b, c, d) {
var ts = (t/=d)*t;
var tc = ts*t;
return b+c*(tc + -3*ts + 3*t);
}
draw();
