JavaScript 实现前端分页导航栏完整示例

<body>
 <!--分页导航条 -->
 <div class="page" id="pag" align="center">
 <!--<a href="javascript:void(0);" onclick="js_method($(this).html())">4</a> -->
 </div>
</body>

<script type="text/javascript">
 $(function () {　
 //这里通过ajax查询到总记录数totalCount
 //设定每页显示记录数pageSize,算出总页数totalPageNum
  js_method(1,10);
 });
 /**
 * 传入当前页和和总页数
 */
 function js_method(currentPageNum,totalPageNum) {
 currentPageNum = Number(currentPageNum);
  var startPageNum = currentPageNum - 2; //起始页
  var endPageNum = currentPageNum + 2; //结束页
  $("#pag").text("") //清空导航条
  if (startPageNum <= 0) {
  startPageNum = 1
  endPageNum = startPageNum + 4
  }
