循环遍历RaphaelJS集合

Looping through RaphaelJS sets

我正在尝试通过一系列RaphaelJS集进行循环。

我有一系列箭头形状(集合)。我希望能够循环遍历它们。

var migration1 = c.set(c.path("M129.045,368.584c0,0,19.155-13.9,23.374-50.593 c2.283-19.858-10.22-31.366-18.958-36.886").attr({fill: "none", "stroke-width": 3, stroke: "#990000"}), c.path("M139.728,278.292L135.038 282.091 134.516 288.104 125.493 277.021 z").attr({fill: "#990000", "stroke-width": 0}), c.path("M136.059,375.577c0,0,42.113-48.3,94.441-84.818 c55.985-39.072,143.717-72.937,171.049-83.015").attr({fill: "none", "stroke-width": 3, stroke: "#990000"}), c.path("M399.536,214.469L399.827 208.441 395.689 204.047 409.966 204.699 z").attr({fill: "#990000", "stroke-width": 0}));

我试过:

for (i=1<=5;i++){
   this['migration'+i].hide();
}

…这样我就可以有一个按钮，按顺序显示它们:

var current=1;
$('#next').click(function(){
   this['migration'+current].hide();
   current++;
   this['migration'+current].show();
})

使用'this'似乎不正确，但我不确定如何连接集名称以瞄准它。

提前感谢。

你可以创建一个集合数组…

var migrations =[ c.set(...), c.set(...), c.set(...), c.set(...), c.set(...)];
那么你的代码看起来像: 
var current=1;
$('#next').click(function(){
   migrations[current].hide();
   migrations[current++].show();
})

我使用以下方法来隐藏传递给函数的set作为'text':

function hideSet(set) { 
    set=eval(set);
    set.forEach( function(e){ e.hide(); } ) 
}

使用this来切换

hideSet('setname');
