Question

我的哈希数组是下面的一个。

[{"status"=>"Submitted", "reachable"=>false}, 
{"status"=>"Replied", "reachable"=>false}, 
{"status"=>"Answered", "reachable"=>false}, 
{"status"=>"Assigned", "reachable"=>false}, 
{"status"=>"Started", "reachable"=>true}, 
{"status"=>"Closed", "reachable"=>false}, 
{"status"=>"Canceled", "reachable"=>true}]

我需要＆＃34; status＆＃34;值并在带有嵌入式ruby代码的html下拉列表中显示它们。你们中的任何人都可以让我知道示例代码吗？我对ruby很新，并且在迭代中混淆并在下拉列表中显示值。

是，如下：

array = [{"status"=>"Submitted", "reachable"=>false}, 
        {"status"=>"Replied", "reachable"=>false}, 
        {"status"=>"Answered", "reachable"=>false}, 
        {"status"=>"Assigned", "reachable"=>false}, 
        {"status"=>"Started", "reachable"=>true}, 
        {"status"=>"Closed", "reachable"=>false}, 
        {"status"=>"Canceled", "reachable"=>true}]

p array.map{|h| h["status"] }
# >> ["Submitted", "Replied", "Answered", "Assigned", "Started", "Closed", "Canceled"]
