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.VeVB.COm 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>    <tr><td>测试编号2</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号3</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号4</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号5</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号6</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号7</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号8</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号9</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号10</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号11</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号12</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号13</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号14</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号15</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号16</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号17</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号18</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号19</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号20</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号21</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号22</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号23</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号24</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号25</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号26</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号27</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号28</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号29</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号30</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号31</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号32</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号33</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号34</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号35</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号36</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号37</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号38</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号39</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>    <tr><td>测试编号40</td><td>25</td><td>单元格1</td><td>单元格2</td></tr>  </table>  <table width="60%" align="right">    <tr><td><div id="barcon" name="barcon"></div></td></tr>  </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.VeVB.COm/code/HtmlJsRun测试运行效果如下：
