Question

我是拉斐尔的新手，我想要多个div的raphael动画。目前我有单个div的动画。但我无法做多个div它会发生冲突。

以下是代码

HTML

<div class="diagram"></div>
        <div class="get">
        <div class="arc">
                <span class="text">JavaScript</span>
                <input type="hidden" class="percent" value="95" />
                <input type="hidden" class="color" value="#97BE0D" />
        </div>
            <div class="arc">
                <span class="text">CSS3</span>
                <input type="hidden" class="percent" value="90" />
                <input type="hidden" class="color" value="#D84F5F" />
            </div>
       </div>

<div class="diagram"></div>
        <div class="get">
        <div class="arc">
                <span class="text">JavaScript</span>
                <input type="hidden" class="percent" value="95" />
                <input type="hidden" class="color" value="#97BE0D" />
        </div>
            <div class="arc">
                <span class="text">CSS3</span>
                <input type="hidden" class="percent" value="90" />
                <input type="hidden" class="color" value="#D84F5F" />
            </div>
       </div>

JAVASCRIPT

var o = {
    init: function(){
        this.diagram();

    },
    random: function(l, u){
        return Math.floor((Math.random()*(u-l+1))+l);
    },
    diagram: function(){
        var r = Raphael($('.diagram'),600,600),  //need effects for all the div
            rad =  3,
            defaultText = 'Skills',
            speed = 250;

        r.circle(300, 300, 20).attr({ stroke: 'none', fill: '#193340' });

        var title = r.text(300, 300, defaultText).attr({
            font: '12px Arial',
            fill: '#fff'
        }).toFront();

        r.customAttributes.arc = function(value, color, rad){
            var v = 3.6*value,
                alpha = v == 360 ? 359.99 : v,
                random = o.random(91, 240),
                a = (random-alpha) * Math.PI/180,
                b = random * Math.PI/180,
                sx = 300 + rad * Math.cos(b),
                sy = 300 - rad * Math.sin(b),
                x = 300 + rad * Math.cos(a),
                y = 300 - rad * Math.sin(a),
                path = [['M', sx, sy], ['A', rad, rad, 0, +(alpha > 180), 1, x, y]];
            return { path: path, stroke: color }
        }

        $('.get').find('.arc').each(function(i){
            var t = $(this), 
                color = t.find('.color').val(),
                value = t.find('.percent').val(),
                text = t.find('.text').text();

            rad += 17;  
            var z = r.path().attr({ arc: [value, color, rad], 'stroke-width': 12 });

            z.mouseover(function(){
                this.animate({ 'stroke-width': 20, opacity: .75 }, 1000, 'elastic');
                if(Raphael.type != 'VML') //solves IE problem
                this.toFront();
                title.stop().animate({ opacity: 0 }, speed, '>', function(){
                    this.attr({ text: text + '\n' + value + '%' }).animate({ opacity: 1 }, speed, '<');
                });
            }).mouseout(function(){
                this.stop().animate({ 'stroke-width': 12, opacity: 1 }, speed*4, 'elastic');
                title.stop().animate({ opacity: 0 }, speed, '>', function(){
                    title.attr({ text: defaultText }).animate({ opacity: 1 }, speed, '<');
                }); 
            });
        });

    }
}
$(function(){ o.init(); });

我已经用了一段时间了，所以如果我错了，请纠正我，但是：

var r = Raphael($('.diagram'),600,600),  //need effects for all the div
            rad =  3,
            defaultText = 'Skills',
            speed = 250;

Raphael对象创建一个画布，然后你操纵它，这里你有多个div。 Raphael期待单个元素的问题（为什么作者使用id而不是styleclass）以及返回元素数组的问题？

如果这是问题，请先尝试获取所有div，然后为每个div执行此代码，而不是将所有div传递给此函数。

Raphael动画为多个div
