JS代码实现table数据分页效果
作者：嗑瓜子儿gf
这篇文章主要介绍了JS代码实现table数据分页效果的相关资料,非常不错，代码简答易懂，非常实用，需要的朋友可以参考下
第一个：实现的很常见很简单的显示页数翻页
效果图：
•这是HTML代码，很简单滴（我好像看到了被嫌弃的小眼神）
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-"> <script src="js/jquery-...js"></script> <script src="js/demo.js"></script> <link rel="stylesheet" href="js/demo.css"/> <title></title> </head> <body> <table width="" border=""> <thead> <tr> <th>姓名</th> <th>性别</th> <th>编号</th> <th>年龄</th> </tr> </thead> <tbody> <tr> <td>张三</td> <td>男</td> <td></td> <td></td> </tr> <tr> <td>tom</td> <td>男</td> <td></td> <td></td> </tr> <tr> <td>李四</td> <td>男</td> <td></td> <td></td> </tr> <tr> <td>二蛋</td> <td>男</td> <td></td> <td></td> </tr> <tr> <td>二丫</td> <td>女</td> <td></td> <td></td> </tr> </tbody> </table> </body> </html>
•下面就是JS代码了
$(function(){
var $table=$('table');//获取表格对象
var currentPage=;//设置当前页默认值为
var pageSize=;//设置每一页要显示的数目
$table.bind('paging', function () {
$table.find('tbody tr').hide().slice(currentPage*pageSize,(currentPage+)*pageSize).show();
//先将tbody中所有的行隐藏，再通过slice结合当前页数和页面显示的数目展现数据
});
var sumRows=$table.find('tbody tr').length;//获取数据总行数
var sumPages=Math.ceil(sumRows/pageSize);//得到总页数
var $pager=$('<div class="page"></div>');
for(var pageIndex=;pageIndex<sumPages;pageIndex++){
$('<a href="#"><span>'+(pageIndex+)+'</span></a>').bind("click",{"newPage":pageIndex},function(event){
currentPage=event.data["newPage"];
$table.trigger("paging");
//为每一个要显示的页数上添加触发分页函数
}).appendTo($pager);
$pager.append(" ");
}
$pager.insertAfter($table);
$table.trigger("paging");
});
第二个：实现前进页和后退页
效果图：
•这是全部代码，用得原生JS，依然还是很简单滴（好像对原生js有种莫名的喜爱，有木有）
