拉斐尔订购物品

问题描述

我正在尝试订购Raphael物品。我没有决定何时创建对象的选项，但是我想在创建对象后使一组对象出现在一组其他对象后面。有人可以帮我这么做吗？

I'm trying to order Raphael objects. I don't have the option of deciding when the objects are created, but I'd like to make a group of objects appear behind a group of other objects after they've been created. Can anybody help me do this?

谢谢。

推荐答案

集团您在两个中的项目，并使用或：

Group you items in two sets and position the sets relative to each other with insertBefore or insertAfter:

var front = paper.set();
front.push(front1, front2);

var back = paper.set();
back.push(back1, back2);

front.insertBefore(back);

此外，如果您的物品在数组中，您可以使用 apply 为方便起见：

Also if you have your items in arrays you can use apply for convenience:

var frontItems = [front1, front2];
front.push.apply(null, frontItems);
