功能问题Javascript Sum [英] Problem with function Javascript Sum
问题描述
你好。
我有这个功能:
嗨...
欢迎来到TSDN ......
i认为不是以你想要的方式工作。请显示与此问题相关的html ...因为我认为nelementi应该是您的表单中包含的一些文本框?
亲切的问候
< blockquote>嗨
好吧,我认为你的代码中存在逻辑错误,但我可以看到你想要做什么。所以我为你编写代码。我希望它你想要的。

Hi there.
I have this Function:
hi ...
welcome to TSDN ...
i think that doesn''t work the way you intended. please show your html relating to this problem too ... because i assume nelementi should be a number of textboxes contained by your form?
kind regards
hi
well,I think there''s a logical error in your code,but I can see what you want to do.so I write a code for you.I hope it''s you want.
