轨忽略添加到阵列

Question

我这里有这样一串代码：

doc.xpath("//script[@type='text/javascript']/text()").each do |text| 
     if text.content =~ /more_options_on_polling/ 
     price1 = text.to_s.scan(/\"(formatted_total_price)\":\"(.+?)\"/).uniq 
     description = text.to_s.scan(/\"(ticket_desc)\":\"(.+?)\"/).uniq 
     price = price1 + description 
     testing = price1.map{|a| { a[0] => a[1] } } 
     desc = description.map{|a| { a[0] => a[1] } } 
     respond_to do |format| 
      format.json { render :json => {:testing => testing, 
              :desc => desc }} 
     end 
     end 

在递减

现在，它返回：

"desc": [ 
    { 
     "ticket_desc": "Later Owl Ticket" 
    }, 
    { 
     "ticket_desc": "Later Owl Ticket+Collector Ticket &#64 extra £4.95 per ticket" 
    }, 
    { 
     "ticket_desc": "Later Owl + Chance For VIP Upgrade" 
    }, 
    { 
     "ticket_desc": "VIP Ticket" 
    }, 
    { 
     "ticket_desc": "VIP Ticket + Collector Ticket &#64 extra £4.95 per ticket" 
    }, 
    { 
     "ticket_desc": "Skydeck Package" 
    }, 
    { 
     "ticket_desc": "5 Person Skydeck Table" 
    }, 
    { 
     "ticket_desc": "7 Person Skydeck Table" 
    }, 
    { 
     "ticket_desc": "10 Person Skydeck Table" 
    } 
    ] 

什么IM希望是内部一个+号什么被忽略。因此，最好的回应是这样的：

"desc": [ 
    { 
     "ticket_desc": "Later Owl Ticket" 
    }, 
    { 
     "ticket_desc": "VIP Ticket" 
    }, 
    { 
     "ticket_desc": "Skydeck Package" 
    }, 
    { 
     "ticket_desc": "5 Person Skydeck Table" 
    }, 
    { 
     "ticket_desc": "7 Person Skydeck Table" 
    }, 
    { 
     "ticket_desc": "10 Person Skydeck Table" 
    } 
    ] 

我目前正在做这跟轨，但我renderign成通过JavaScript/AJAX的观点，所以，如果你有任何想法，我能做些什么让有我知道:)

继承人的AJAX：

for (var i = 0; i < json.testing.length; i++) { 
    var section = json.testing[i].formatted_total_price; 
    var desc = json.desc[i].ticket_desc; 

Answer 1

那么，一个选择是在desc哈希使用选择。例如，与desc =开头的行后，您可以添加：

desc.select! { |a| !a['ticket_desc'].include?("+") } 

如果你想保持原来的递减，使用非破坏性的选择，并把结果在一个新的变量：

desc_wo_plus = desc.select { |a| !a['ticket_desc'].include?("+") }
