靠。是这个问题。晕倒了。我把它改过来了。但是第95行又报错了。就是这一行：c1.innerHTML = "<input type=text name="popgroup" ln="+allCount+" class=tableData />";/行95，缺少';'
这一行应该没敲错啊。
引号错误，注意单引号双引号的匹配。
c1.innerHTML = "<input type=text name='popgroup' ln='+allCount+' class=tableData />";
这个对的，刚才的随手写错了。
c1.innerHTML = "<input type=text name='popgroup' ln="+allCount+" class=tableData />";

找本javascript的手册看看，基本语法失误；
我刚学js不久，这一行里这个代码我看不懂，
ln="+allCount" 为什么要两个 “＋”号。
这样不行吗： ln="allCount"
而且为什么这里用双引号，而name='popgroup'用单引号？
谢谢 myvicy的回答。
popgroup处有错了
应该是+popgroup+
不过你放心,这个改完了还有错
我本来想改到能运行,但我伤心了,改不出来
完全看不懂你的企图.
zhaoxiaoyangto zhaoxiaoyang,是这个样子的，我刚才贴的程序没有写完。目前只实现了贴加行的功能。本来里面还有一个选择一行的功能，就是function lightOn(ln)所实现的功能。但是我我用鼠标点选，一点反映也没有。但是没有报错。
不知道你现在懂些了我的企图没有。
在myvicy的帮助下我实现了添加行的功能，下面是我完整的代码：

to zhaoxiaoyang,popgroup处有错了
应该是+popgroup+为什么要用"+popgroup+"了，这里用两个加号是什么意思。谢谢。
