IE / JS：减少对象

my javascript Application works on firefox and chrome very well. But it seams to be broken on Internet Explorer (IE 8).

我的javascript应用程序非常适用于firefox和chrome。但它的接缝在Internet Explorer（IE 8）上被破坏了。

I did not get an error Message on the console-log. By debugging the code I notice, that the application breaks on the following line:

我在控制台日志中没有收到错误消息。通过调试我注意到的代码，应用程序在以下行中断：

 series.reduce(visit, []);

The whole function exits at this point. I know, that reduce works for arrays, but console.info(typeof(series)) tells: object

此时整个功能退出。我知道，reduce适用于数组，但是console.info（typeof（series））告诉：object

But this object exactly looks like an array - and it works on FF/Chrome. Could this be the reason, why IE stops processing the function at this point? And: how to handle this at IE?

但是这个对象看起来就像一个数组 - 它适用于FF / Chrome。这可能是为什么IE此时停止处理功能的原因？并且：如何在IE处理这个？

Thank you.

谢谢。

Reduce is not supported until IE 9 : https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/array/reduce#Browser_compatibility

IE 9之前不支持Reduce：https：//developer.mozilla.org/en/JavaScript/Reference/Global_Objects/array/reduce#Browser_compatibility

That link does have a workaround bit of code for browsers that don't support reduce.

对于不支持reduce的浏览器，该链接确实有一些代码解决方法。
