JQuery realizes that the click effect of a tag is disabled

a label example

<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>

Disable a tag

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

Restore a tag

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