请你看一下this sample,让我知道如何在Raphaël上清除一套图纸?
var paper = Raphael('my-canvas', 500, 500);
var rect = paper.rect(100, 100, 100, 100);
var st = paper.set();
st.push(
paper.circle(10, 10, 5),
paper.circle(30, 10, 5)
);
st.attr({fill: "red"});
$(".clear").on("click",function(){
st.clear();
});

如果要完全删除元素,可能需要使用element.remove()方法。从一组中,您可以在其上应用forEach。所以代码看起来像......
var paper = Raphael('my-canvas', 500, 500);
var rect = paper.rect(100, 100, 100, 100);
var st = paper.set();
st.push(
paper.circle(10, 10, 5),
paper.circle(30, 10, 5)
);
st.attr({fill: "red"});
$(".clear").on("click",function(){
st.forEach( function(el) {
el.remove();
});
// edit: or shorten it and just have st.remove()
});
