我想让它在选中复选框时搜索特定类别（例如跟随者）。但目前即使我选中复选框，它仍然会搜索输入的关键字。但如果我不选择任何复选框，我只希望它在整个 Twitter 中搜索输入的关键字。有没有人有任何解决方案。

ps(我会写代码搜索追随者，等我想明白之后再关注。)

【解决方案1】：

您认为问题在于，您有另一种形式的复选框，因此当您点击搜索时，它们不会被发送。您需要一种形式的所有输入。

【讨论】：

我现在更新了它并添加了随机搜索词，但目前它只适用于“阿森纳”，应该只是关注者勾选。当两者都被勾选时，它也会搜索“arsenal”而不是“chelsea”，当只勾选“关注”时，它会搜索输入的关键字而不是“liverpool”。任何想法我现在做错了什么？

  @keyword = "No keyword entered"
  @results = []

  unless params[:filter].nil?
      @tick_box1 = params[:filter][:follower] == 'on'
      @tick_box2 = params[:filter][:following] == 'on'
  end

  if (@tick_box1) && (@tick_box2)
    @results = @client.search('chelsea').take(20)
  elsif (@tick_box1) && (!@tick_box2)
    @results = @client.search('arsenal').take(20)
  elsif (!@tick_box1) && (@tick_box2)
    @results = @client.search('liverpool').take(20)
  else
    unless params[:keyword].nil?
      @keyword = params[:keyword]
      @results = @client.search(@keyword).take(20)
    end

    unless params[:use_keyword].nil?
      @results = @client.search(keywords[0]).take(20)
    end
  end
    erb :search
