ie百分比的圆

其实一开始我是做成这样的，直接先用ul定义一个灰色的园，然后用jq获取里面的百分比的值，把值*3.6取整，然后循环一遍每一个值画一条旋转的直线。

    <div class="percentage-img">
        <ul>
            <li><span></span></li>

         <span data-percentage="80"></span>
    </div>
</body>
<script>
    var explorer = navigator.userAgent;
    var per1 , span1 = $(".percentage-img>span").data("percentage");
    $(".percentage-img>span").html(span1 + "%");
    per1 = parseInt(span1 * 3.6);
    pertenage(per1, ".percentage-img");
    function pertenage(num, cl) {
        var circleBorder = "";
        for (var i = 0; i < num; i++) {
            circleBorder += "<li style='-webkit-transform:rotate(" + i + "deg);-ms-transform:rotate(" + i + "deg);transform:rotate(" + i + "deg)'></li>"
        }
        $(cl + ">ul").html(circleBorder);
    }
</script>
</html>

但是这个ie上会让浏览器变得比较卡而已也不兼容。
然后我就把ie的样式改成

而除ie以外的浏览器还是没变。
这个的思路，我一开始以为用ul画个圆加上超出隐藏，li就宽度和ul一样，高度就是获取百分比*ul的高度的值，但是我IE的圆兼容是用了ie-css.htc这个文件去兼容的。虽然在ie上ul显示是一个圆，但是ul其实实际上还是一个矩形，所以超出隐藏就得li也所会显示为一个矩形，并不能像我想象那样li变成上图那样。
然后我就想能不能以li获取的值来做显示隐藏，而在里面加个span来显示圆。
