polymer-2.0 - Polymer paper-radio-group 允许选择多个单选按钮

Question

我正在尝试添加一个单选组，但单选按钮允许多项选择。我只导入了 paper-radio-group。如何让它一次只选择一个单选按钮。

<paper-radio-group>
      <p>1) <paper-radio-button name="one">Collect is an aggregation and reduce is a fold operation</paper-radio-button></p>
      <p>2) <paper-radio-button name="two">Collect is an fold and reduce is a aggregation operation</paper-radio-button></p>
      <p>3) <paper-radio-button name="three">Both are the same</paper-radio-button></p>
      <p>4) <paper-radio-button name="four">None of the above</paper-radio-button></p>
      </paper-radio-group>

Answer 1

迟到最好不要:) 添加您想要添加的任何标签，但在纸单选按钮标签内，应该没问题。

<paper-radio-group  >
      <paper-radio-button name="one"> <p>1)Collect is an aggregation and reduce is a fold operation</p></paper-radio-button>
       <paper-radio-button name="two"><p>2)Collect is an fold and reduce is a aggregation operation</p></paper-radio-button>
     <paper-radio-button name="three">  <p>3)Both are the same</p></paper-radio-button>
       <paper-radio-button name="four"><p>4)None of the above</p></paper-radio-button>
      </paper-radio-group>
