废话不多说，直接给大家贴代码了。
具体代码如下所示：
<!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta charset="utf-8"> <title>点击按钮文字变成input框，点击保存变成文字</title> <style type="text/css"> table{ text-align: center; font-size: 14px;} table>thead>tr>th{ font-weight: normal;} .text-right{ padding-right:73px; text-align: right;} .text{ width: 50px; height: 30px; border: 1px solid #ddd; text-align: center;} </style> <script type="text/javascript" src="https://www.jb51.net/js/jquery.min.js"></script> </head> <body> <table> <thead> <tr> <th>品名</th> <th>件数</th> </tr> </thead> <tbody> <tr> <td>iPhone6s</td> <td>2</td> </tr> <tr> <td>小米5</td> <td>5</td> </tr> </tbody> <tfoot> <tr> <td colspan="2"> <button type="button">修改</button> </td> </tr> </tfoot> </table> <script type="text/javascript"> function change(obj){ var xg=$(obj).html(); if(xg=='修改'){ $('.edit').each(function(){ var old=$(this).html(); $(this).html("<input type='text' value="+old+" >"); }) $(obj).html('保存'); }else if(xg=='保存'){ $('input[name=editname]').each(function(){ var old=$(this).html(); var newfont=$(this).parent('td').parent('tr').children().find('input').val(); $(this).parent('td').html(newfont); }) $(obj).html('修改'); } } </script> </body> </html>
