你可以简单地使用jquery .attr来获得所需的输出。

console.log($("#val").attr('data-tabval'))

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#angular_code" role="tab" id="angular_code-tab" data-toggle="tab" aria-controls="angular_code">
   <span id="val" data-tabval="test123" class="text">test here</span>
</a>
