Ruby-访问元素多维数组

-4

你能帮助的人我改变/逻辑组织log项Ruby-访问元素多维数组

input_array = [ 
    ["2/6/2014", "13:31:12", "IN", "application1", "user1", "machine1"] 
    ["2/6/2014", "13:31:12", "IN", "application2", "user2", "machine2"] 
    ["2/6/2014", "13:31:52", "IN", "application3", "user3", "machine3"] 
    ["2/6/2014", "13:38:37", "OUT", "application1", "user1", "machine1"] 
    ["2/6/2014", "14:46:37", "OUT", "application2", "user2", "machine2"] 
    ["2/6/2014", "15:56:37", "OUT", "application3", "user3", "machine3"] 
]

如何这个阵列中访问单个元素..如2/6/2014或application1？

当我做input_array[1][4]，所需的输出是...

"application1" # and not 6 ... its giving me the 4 character in line 1

感谢您的帮助！

'线'是什么？用这个间距，你的代码是无效的。 – sawa

即使你使那个特定的语法有效，你仍然会得到一个字符串而不是一个数组。 –

也许你的意思是这个：

input_line = [ 
    ["2/6/2014", "13:31:12", "IN", "application1", "user1", "machine1"], 
    ["2/6/2014", "13:31:12", "IN", "application2", "user2", "machine2"], 
    ["2/6/2014", "13:31:52", "IN", "application3", "user3", "machine3"], 
    ["2/6/2014", "13:38:37", "OUT", "application1", "user1", "machine1"], 
    ["2/6/2014", "14:46:37", "OUT", "application2", "user2", "machine2"], 
    ["2/6/2014", "15:56:37", "OUT", "application3", "user3", "machine3"]]

？

然后，您可以使用语法input_array[i][j]没有问题！

是的，你说得对。必须弄清楚如何在每个数组之后得到逗号......感谢队友 – skumo

你提出的代码中有一个错误，如果你真的确定你的阵列是这样的：

input_array = [ 
    ["2/6/2014", "13:31:12", "IN", "application1", "user1", "machine1"], 
     ["2/6/2014", "13:31:12", "IN", "application2", "user2", "machine2"], 
     ["2/6/2014", "13:31:52", "IN", "application3", "user3", "machine3"], 
     ["2/6/2014", "13:38:37", "OUT", "application1", "user1", "machine1"], 
     ["2/6/2014", "14:46:37", "OUT", "application2", "user2", "machine2"], 
     ["2/6/2014", "15:56:37", "OUT", "application3", "user3", "machine3"] 
    ]

你会那么可以访问阵列，像这样：

2.0.0p195 :054 > input_array[0][0] 
=> "2/6/2014"
