在eclipse中程式設計報錯：Undefined attribute name (role).說明沒有role屬性這是版本不支援問題

<span style="font-family:SimSun;"><ul class="nav nav-tabs" id="ul1">
<li role="presentation"><a href="#">hello</a></li>
<li role="presentation"><a href="#">資料夾</a></li>
<li role="presentation"><a href="#">hhhhh</a></li>
</ul></span>
 

<ul class="nav nav-tabs" id="ul1">
<li data-role="presentation"><a href="#">hello</a></li>
<li data-role="presentation"><a href="#">資料夾</a></li>
<li data-role="presentation"><a href="#">hhhhh</a></li>
</ul>
