使用Bootstrap循环进度条
有什么方法可以创建具有多个不同值的圆：

如下所示：
依赖： jQuery
function sliceSize(dataNum, dataTotal) {
return (dataNum / dataTotal) * 360;
}
function addSlice(sliceSize, pieElement, offset, sliceID, color) {
$(pieElement).append("<div class='slice "+sliceID+"'><span></span></div>");
var offset = offset - 1;
var sizeRotation = -179 + sliceSize;
$("."+sliceID).css({
"transform": "rotate("+offset+"deg) translate3d(0,0,0)"
});
$("."+sliceID+" span").css({
"transform" : "rotate("+sizeRotation+"deg) translate3d(0,0,0)",
"background-color": color
});
}
function iterateSlices(sliceSize, pieElement, offset, dataCount, sliceCount, color) {
var sliceID = "s"+dataCount+"-"+sliceCount;
var maxSize = 179;
if(sliceSize<=maxSize) {
addSlice(sliceSize, pieElement, offset, sliceID, color);
} else {
addSlice(maxSize, pieElement, offset, sliceID, color);
iterateSlices(sliceSize-maxSize, pieElement, offset+maxSize, dataCount, sliceCount+1, color);
}
}
function createPie(dataElement, pieElement) {
var listData = [];
$(dataElement+" span").each(function() {
listData.push(Number($(this).html()));
});
var listTotal = 0;
for(var i=0; i<listData.length; i++) {
listTotal += listData[i];
}
var offset = 0;
var color = [
"cornflowerblue",
"olivedrab",
"orange",
"tomato",
"crimson",
"purple",
"turquoise",
"forestgreen",
"navy",
"gray"
];
for(var i=0; i<listData.length; i++) {
var size = sliceSize(listData[i], listTotal);
iterateSlices(size, pieElement, offset, i, 0, color[i]);
$(dataElement+" li:nth-child("+(i+1)+")").css("border-color", color[i]);
offset += size;
}
}
