这是我做的javascript但尚未完成：

展开 | 选择 | Wrap | 行号

解决方案

欢迎来到TSDN！

使用代码标签伙伴:-)

你知道事件....

看看这段代码.. .....................................模糊（this，this.parentNode.parentNode，getChildren（this），tru e）;>展开 | 选择 | Wrap | 行号

hi ...


欢迎来到TSDN ...


改变了线程标题以更好地描述问题。请...总是使用一个好的主题标题...


亲切的问候

感谢回复人...


i还有点丢失..在我选择了选项后，我按下计算按钮，它应该出现答案，但问题是javascript编码是否正确..如果它错了，你能告诉我错误的部分在哪里吗？


希望我刚刚制作的所有编码都不是完全错误的.. *手指交叉*


谢谢

thanks for the replies guys...

i still kinda lost here.. after i make choices of the options then i press "calculate" button, it should appears the answer but the thing is whether the javascript coding is right or not.. if it''s wrong, could you please tell me where is the wrong part?

hopefully all the coding i just made wasn''t completely wrong.. *finger crossed*
