没有什么输出

我不知道我在做什么错，我无法获得任何输出。语言是javascript。没有什么输出

继承人的问题

编写一个程序，决定许多男性和女性是如何生活在招生记录集的邮编地区的每个。输出的邮政编码，男性总数，以及每个邮政编码的女性总数。在报告结尾显示总计男性和女性。

记录集中有5个邮政编码。邮政编码为：53711, 53712,53713,53714,53716。这些邮政编码值不言自明，因为邮政编码为，可用作程序中的文字 - 它们是避免通用课程标准的例外在程序的主要部分使用文字。由于每条记录都是，请查询性别代码字段和邮政编码字段，然后为该性别和递增合适的计数器变量，并为该性别和邮编组合添加合适的计数器变量。

必须至少有五（5）个功能。

的输出需要像这样
53711: Males: 5 Females: 2 
53712: Males: 9 Females: 9 
53713: Males: 11 Females: 3 
53714: Males: 4 Females: 6 
53716: Males: 1 Females: 0 

Total Males: 30 
Total Females: 20 

继承人我的代码不管你的其他问题

您是否检查了浏览器控制台的错误？你已经尝试过哪些调试步骤？我们确实需要[SSCCE]（http://sscce.org），而不是数百行代码。 – Matt

你可以构造一个单独的字符串并写入一次..也可以看看arras和可能的情况。无论如何。 – Jonast92

'var ZERO = 0;'以防万一'ZERO'的值改变！ –

，你是不是叫displayZipCodeData()任何地方，所以没有被执行的代码。
