javascript – raphael.js如何将id添加到路径中

我刚开始使用Raphael.js,我很难在路径中添加id.我已经阅读了很多关于如何做的帖子,但我认为我的文件设置方式不允许我轻松翻译这些解决方案.

我有一个init.js文件和一个path.js文件

init.js

var r = Raphael('man', 500, 573),
    attributes = {
        fill: '#204ad3',
        opacity: '0.0',
        'stroke-linejoin': 'round'

    },
arr = new Array();

for (var muscles in paths) {

    var obj = r.path(paths[muscles].path);

    obj.attr(attributes);

    arr[obj.id] = muscles;

    obj
    .hover(function(){
        this.animate({
            fill: '#204ad3',
            opacity: '0.3'
        }, 300);
    }, function(){
        this.animate({
            fill: attributes.fill,
            opacity: attributes.opacity
        }, 300);
    })
    .click(function(){
        document.location.hash = arr[this.id];

        var point = this.getBBox(0);

        $('#man').next('.point').remove();

        $('#man').after($('<div />').addClass('point'));

        $('.point')
        .html(paths[arr[this.id]].name)
        .prepend($('<a />').attr('href', '#').addClass('close').text('Close'))
        .prepend($('<img />').attr('src', 'flags/'+arr[this.id]+'.png'))
        .css({
            left: point.x+(point.width/2)-80,
            top: point.y+(point.height/2)-20
        })
        .fadeIn();

    });

    $('.point').find('.close').live('click', function(){
        var t = $(this),
            parent = t.parent('.point');

        parent.fadeOut(function(){
            parent.remove();
        });
        return false;
    });
}

path.js文件:

var paths = { 
    neck: {
        name: 'Neck',
    path: 'd="M412.294,73.035c0,0,7.661,28.869,9.406,31.78c1.746,2.911,4.657,2.911,9.896,2.911 s9.313-1.746,9.896-5.239c0.582-3.493,6.985-28.523,6.985-28.523s-2.963,2.599-6.232,5.984c-2.543,2.632-7.2,5.904-11.088,5.904 c-3.889,0-6.705-2.431-10.367-5.04C418.063,78.868,418.08,79.22,412.294,73.035z"',

},
}

生成的SVG元素没有id,也不知道如何在其中获取.任何建议/帮助将不胜感激.

这会将id属性添加到svg路径元素:

var id = 0;

for (var muscles in paths) {

    var obj = r.path(paths[muscles].path);
    obj.node.id = "muscles_or_whatever_you_want_" + id;
    id++
