所以我有一個繪製路徑的函數。我想沿着這些不同的路徑創建一些圈子，而圓圈始於正確的位置（在路徑的第一個點），當我嘗試沿着路徑對它們進行設置時，它們會失靈。我究竟做錯了什麼？拉斐爾對象不會正確沿着路徑生成動畫
你可以看到我的代碼上jsfiddle或在這裏：
function commerce() {
Raphael("commercebounce", function() {
var r = this;
function pathfade() {
var a = .1,
b = .4,
c = [0, 2],
d = [50, 300],
e = [150, 800],
fz = [150, 350],
g = d[0] + Math.random() * (d[1] - d[0]),
h = e[0] + Math.random() * (e[1] - e[0]),
i = fz[0] + Math.random() * (fz[1] - fz[0]),
colours = ["215,10,45", "115,115,115"],
stroke = ["", "- "];
opacity = a + Math.random() * (b - a), colour = "rgb(" + colours[Math.round(Math.random())] + ")", strokeW = c[Math.round(Math.random())];
j = r.path("M 0 " + g + " C 0 " + g + " " + (h - 100) + " " + g + " " + h + " 400 M " + h + " 400 C " + h + " 400 " + (h + 100) + " " + g + " 960 " + i).attr({stroke: colour,"stroke-dasharray": stroke[Math.round(Math.random())],"stroke-opacity": .1});
return j

r.customAttributes.along1 = function (v) {
