检测按钮所在行

我想通过点击button触发change（this）事件，获取按钮所在行的id，然后调用changeTotext()方法，使所需要的单元格变换成文本框来进行修改数据，function change（obj）{}方法不会写。

	
			<?php	$db = mysql_connect('localhost','root','root');	mysql_select_db('ec',$db);	if (!$db)	  {	  die('Could not connect: ' . mysql_error());	  }	$result = mysql_query("select * from goods");	echo "";	$n = 0;	while($row = mysql_fetch_array($result))	  {	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "";	  echo "".     		"";	  echo "";	   	echo "";	  	++$n;	  }		mysql_close($db);?>

把单元格的内容放在 div 中，动态设置 div 的 contenteditable 属性就可实现修改
