我希望点击“updqte”按钮后按钮变成“save”，然后单元格变成文本框，编辑完文本框后点击“save”结果提交给了数据库。按钮改变用js做完了，其他的实在是不回了，各位大神帮帮忙吧。

1.给你的save按钮一个onclick方法点击后触发
2.用ajax 提交参数到后台，调用php程序
3.然后将接收内容提交到数据库
4.成功or失败返回到页面

我表上红色的部分是一个数组，我想让这个数组变成动态的，要不然所有按钮都只操作一条数据。有什么好办法没？

1.给你的save按钮一个onclick方法点击后触发
2.用ajax 提交参数到后台，调用php程序
3.然后将接收内容提交到数据库
4.成功or失败返回到页面
不好意思是第24行，刚才没标上颜色。

要是我做的话就是都设为隐藏的
一个.show()
一个.hide()
当点击完一个操作就触发函数转换到另一个按钮

建议lz选择jq选择器都很强大
搭配ajax 足够完成大量input提交工作

第24行的那个数组能不能改成动态的，要不然所有按钮都只操作同一条数据，应该怎么改啊？

<html><head><script type="text/javascript" src="/jquery/jquery.js">
</script><script type="text/javascript">
$(document).ready(function(){  $(".btn1").click(function(){  
$(".btn1").hide();  $(".btn2").show();  });  
$(".btn2").click(function(){  
$(".btn1").show();  
$(".btn2").hide();  
});
});
</script></head><body><button class="btn1" style="display:none">update</button><button class="btn2">save</button></body></html>
