我刚开始使用 Raphael.js，我很难为路径添加 id。我已经阅读了很多关于如何做到这一点的帖子，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

初始化.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，我也不知道如何在其中获取一个。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++

    //....

为 SVG 元素添加 id paper.path( path data ).node.id = 'pathIdString';.... 测试...尝试alert( document.getElementById("pathIdString").id );。应该返回 id

看起来您要做的是在单击的路径上方弹出一个带有图像和关闭链接的 div。问题是您将路径对象的 Raphael id 与paths数组中的索引混淆了。您可能希望arr完全消除并通过闭包将索引传递给您的处理程序：

.click(function(index) { return function() {
    document.location.hash = index;

    var point = this.getBBox(0);

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

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

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

}; }(muscles));
