本文实例讲述了JS基于封装函数实现的表格分页。分享给大家供大家参考，具体如下：

HTML代码：

<html>
<head>
<meta charset='utf-8'>
<title>www.jb51.net js表格分页</title>
<script type="text/javascript" src="script.js"></script>
 <style type="text/css">
  #idData {color: red;border: solid;text-align: center;}
  a{text-decoration: none;}
 </style>
</head>
<body>
  <table id="idData" width="70%">
    <tr><td>测试编号1</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>

  </table>
  <table width="60%" align="right">

  </table>
</body>
</html>
<script type="text/javascript" language="javascript">
window.onload = function(){
  goPage(1,10);
};
</script>

script.js：

/**
 * 分页函数
 * pno--页数
 * psize--每页显示记录数
 * 分页部分是从真实数据行开始，因而存在加减某个常数，以确定真正的记录数
 * 纯js分页实质是数据行全部加载，通过是否显示属性完成分页功能
 **/
function goPage(pno,psize){
  var itable = document.getElementById("idData");
  var num = itable.rows.length;//表格所有行数(所有记录数)
  console.log(num);
  var totalPage = 0;//总页数
  var pageSize = psize;//每页显示行数
  //总共分几页
  if(num/pageSize > parseInt(num/pageSize)){
      totalPage=parseInt(num/pageSize)+1;
    }else{
      totalPage=parseInt(num/pageSize);
    }
  var currentPage = pno;//当前页数
  var startRow = (currentPage - 1) * pageSize+1;//开始显示的行 31
    var endRow = currentPage * pageSize;//结束显示的行  40
    endRow = (endRow > num)? num : endRow;  40
    console.log(endRow);
    //遍历显示数据实现分页
  for(var i=1;i<(num+1);i++){
    var irow = itable.rows[i-1];
    if(i>=startRow && i<=endRow){
      irow.style.display = "block";
    }else{
      irow.style.display = "none";
    }
  }
  var pageEnd = document.getElementById("pageEnd");
  var tempStr = "共"+num+"条记录 分"+totalPage+"页 当前第"+currentPage+"页";
  if(currentPage>1){
    tempStr += "<a href=\"#\" onClick=\"goPage("+(1)+","+psize+")\">首页</a>";
    tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage-1)+","+psize+")\"><上一页</a>"
  }else{
    tempStr += "首页";
    tempStr += "<上一页";
  }
  if(currentPage<totalPage){
    tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage+1)+","+psize+")\">下一页></a>";
    tempStr += "<a href=\"#\" onClick=\"goPage("+(totalPage)+","+psize+")\">尾页</a>";
  }else{
    tempStr += "下一页>";
    tempStr += "尾页";
  }
  document.getElementById("barcon").innerHTML = tempStr;
}

使用在线HTML/CSS/JavaScript代码运行工具 http://tools.jb51.net/code/HtmlJsRun测试运行效果如下：
