JQuery实现a标签的点击效果禁用

a标签示例

<ul class="pager">
  <li><a href="#" id="premore" >上一页</a></li>
     <li><span id="nowPage">1</span></li>
     <li><a href="#" id="nextmore">下一页</a></li>
 </ul>

禁用a标签

$('#premore').attr("disabled",true).css("pointer-events","none").css("opacity","0.6");

恢复a标签

$('#premore').attr("disabled",false).css("pointer-events","auto").css("opacity","1");
