너는 진정 전자인을 아는가?

해당 클릭한 정보의 텍스트 추출하기,

기타 클릭한 정보의 href나 li안의 정보를 가져오기 위해서 

attr("href") <--를 사용하시면 됩니다.

<script>
$(document).ready(function(){
  $("ul li a").click(function(){
    var t= $(this).html();
    alert(t);
  });
});
</script>

<ul class="cmt">
      <li><a href="#">A</a></li>
      <li><a href="#">B</a></li>
      <li><a href="#">C</a></li>
      <li><a href="#">D</a></li>
      <li><a href="#">E</a></li>
    </ul>
