Question

一点背景，后端应接收表单，然后根据帖子数据中的过滤器填充新列表。

假设我有这样的标记

<form method="POST" action="/my/app/route/">
  <table>
    <tr>
      <td>
        Name:
       </td>
       <td>
         <input type="text" name="NAME" maxlength="100" size="20" style="width: 90%;"
       </td>
     </tr>
     <tr>
     <td>
       Classes:
     </td>
     <td>
       <select multiple="true" name="CLASSES">
         <option>Painting Composition</option>
         <option>Analysis of Algorithms</option>
         <option>Game Design</option>
         <option>Assembly Language</option>
         <option>Pirate History</option>
       </select>
      </td>
    </tr>
  </table>
</form>

这将显示为文本框和选择框。现在在我的烧瓶中，我想要区别对待文本框和选择框;如果某些内容来自文本框，我只想做一个in语句。 EG，if (textbox): if row[k] not in filter_dict[k]: break

   @app.route('/my/app/route/') 
   def filter_CSV(data):
      filter_dict = dict(request.form)
      return_list = []
      #row looks like this: {"NAME": string, "CLASSES": string}
      for row in data:
        for k, v in filter_dict.iteritems():
          # here is where the check for text box would come
          # else, do this stuff:
          row[k] = row[k].split(', ')
            if not set(row[k]).issuperset(set(filter_dict[k])):
              break
            return_list.append(row)
        return return_list

那怎么会这样呢？

Take a look here at the Flask request object.

您不需要像往常一样将对象放入字典中。您只需访问NAME：request.form ['NAME']

识别/标记烧瓶中的HTML元素
