<style type="text/css">
body{overflow-x:hidden;overflow-y:scroll;width:100%;padding:0;margin:0;background-color:#022d00;}
</style>
<script src="raphael-min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
window.onload = function () {
var paper = Raphael(0, 0, 500, 600);
var path1=paper.path("M114 253").attr({"stroke": "#999", "stroke-width":1});
path1.animate({path: "M114,100c0,50 100-50 100,0c0,50 -100-50 -100"},5000).attr({"stroke": "#999", "stroke-width":1});
});
}

<div id="stroke"></div>

參考解法
方法 1:
Take out one 'lot' of attr for path1
var path1=paper.path("M114 253")
path1.animate({path: "M114,100c0,50 100-50 100,0c0,50 -100-50 -100"},5000).attr({"stroke": "#999", "stroke-width":1});
or
var path1=paper.path("M114 253").attr({"stroke": "#999", "stroke-width":1});
path1.animate({path: "M114,100c0,50 100-50 100,0c0,50 -100-50 -100"},5000);
works for me.
