我想嵌入phone-component.html另一个phone-view-component.html自定义元素。在最后一列中phone-view-component.html有一个“类型”、“提供者”、“数字”——所有文本——和一个按钮——“新建”。我想使用 phone-view-component 中的“New”按钮在第一行的每一行下添加一个由 a 和 ('Delete') 组成的<select>phone - component <datalist>。因此，每次我单击“新建”按钮时，都会插入一个新行。“删除”按钮将删除它所属的行。<tel><button>

到目前为止，我的尝试如下所示：

电话-component.html

<!DOCTYPE html>

<polymer-element name='epimss-phone-component'>   
  <template>
  <roole src="reg-roole.rin" monitor="1"></roole> 
    <table border="1" width="100%">
      <tbody>
        <tr>
          <td>
              <select id="phoneCmbo" selectedIndex='{{phoneSelectedIndex}}' >
                <option value="{{phone}}"
                        template repeat="{{phone in phones}}" >{{phone}}
                </option>
              </select>
          </td>
          <td>
            <input id='providerTxt' type='text' value='{{phone.provider}}' list='providers'>
              <datalist id='providers'>
                  <template repeat='{{provider in providers}}'>
                    <option value='{{provider}}'>{{provider}}</option>
                  </template>
              </datalist>          
          </td>
          <td><input id='num' type='tel' value='{{phone.num}}'>
          </td>
          <td>
              <button id='deleteBtn on-click={{deleteRow}}'></button>
          </td>
          <td>
          </td>
        </tr>
      </tbody>
    </table>
   </template>

   <script type="application/dart">

      @CustomTag( 'epimss-phone-component' )

      {
        @observable Phone phone = new Phone();

        List<String> phones = ['', 'Car', 'Fax', 'Home', 'Home Fax', 'Home Mobile', 
                               'Home Video', 'Mobile', 'Pager', 'Work',

                               'Next-of-Kin Work', 'Tollfree', 'Web Phone'];

        List<String> providers = [ '', 'AT&T', 'Digicel', 'Flow', 'Lime' ];

        int providerSelectedIndex = 0;

        //@observable Map phone = toObservable( new Phone() );
        PhoneElement.created() : super.created();

        void addRow( Event e, var detail, Node target)
        {
          print( 'New row created' );

        }


        void deleteRow( Event e, var detail, Node target)
        {
          print( 'Current row deleted' );

        }


      }

    </script> 
</polymer-element>

phone-view-component.html

        PhoneViewElement.created() : super.created();
      }

    </script> 
</polymer-element>

电话.dart

part of reg_popo;

class Phone extends Observable
{

  String type = '';

  String provider = '';
  String num = '';

}

我不知道如何在每个表列中放置小部件并检索 List 模型中的每一行新数据。

任何帮助表示赞赏。谢谢
