我正在尝试在下面的按钮事件中动态访问不同的全局变量（AvGen.svg1、AvGen.svg2 等），但由于某种原因，即使变量“svg”变得相同（例如AvGen.svg1) 将 AvGen.svg1 直接放入“添加”方法中。

怎么行不通？

AvGen = {

    currSvg: 0,
    svg1: null,
    svg1: null,

    init: function() {
        AvGen.loadSVG();
        AvGen.toolBox();
    },

    loadSVG: function() {
        AvGen.svg1 = [0,0,255.3,298.5,{type:'path',path:'M 35.3 257.2 C 34.4 245.7 45.4 234.1 48.5 223 C 53.6 204.3 55 185 60 166.2 C 69.5 131 69.6 97.1 89.1 65.1 C 103.4 41.7 129.5 5.3 161.3 19.7 C 184.6 30.3 181.3 59.2 188.9 78.9 C 207.5 127.3 228.6 184.8 230.3 237.3 C 231.3 268.6 202.8 261.3 178.2 264 C 149.2 267.1 120 269.6 91 272.2 C 84.2 272.8 75.8 274.2 69 273 C 60.9 271.6 28.9 259.9 31.3 249.2','fill':'#39b54a','stroke':'none','stroke-width':'0','fill-opacity':'1','stroke-opacity':'0'}];

        AvGen.paper = Raphael("avatarBox",300,300);
    },

    toolBox: function() {
       var moveRightBtn = $('#moveRightBtn');

        moveRightBtn.on('click', function(){
            AvGen.paper.clear();
            AvGen.currSvg += 1;

            var svg = 'AvGen.svg' + AvGen.currSvg;
            console.log(svg); // <--- AvGen.svg1
            AvGen.paper.add(svg);
            // AvGen.paper.add(AvGen.svg1); <--- works
        });
    },
};

编辑：单击按钮时，我在控制台中没有任何错误。

尝试这个：

AvGen = {

    currSvg: 0,
    svg: [],

    init: function() {
        AvGen.loadSVG();
        AvGen.toolBox();
    },

    loadSVG: function() {
        AvGen.svg.push([0,0,255.3,298.5,{type:'path',path:'M 35.3 257.2 C 34.4 245.7 45.4 234.1 48.5 223 C 53.6 204.3 55 185 60 166.2 C 69.5 131 69.6 97.1 89.1 65.1 C 103.4 41.7 129.5 5.3 161.3 19.7 C 184.6 30.3 181.3 59.2 188.9 78.9 C 207.5 127.3 228.6 184.8 230.3 237.3 C 231.3 268.6 202.8 261.3 178.2 264 C 149.2 267.1 120 269.6 91 272.2 C 84.2 272.8 75.8 274.2 69 273 C 60.9 271.6 28.9 259.9 31.3 249.2','fill':'#39b54a','stroke':'none','stroke-width':'0','fill-opacity':'1','stroke-opacity':'0'}]);

        AvGen.paper = Raphael("avatarBox",300,300);
    },

    toolBox: function() {

        moveRightBtn.on('click', function(){
            AvGen.paper.clear();
            AvGen.currSvg += 1;

            var svg = AvGen.svg[AvGen.currSvg-1];
            AvGen.paper.add(svg);
        });
    },
};
