JS基于封装函数实现的表格分页完整示例
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> <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.jb51.net/code/HtmlJsRun测试运行效果如下:
