只要统计radio里按yes的次数,怎样实现,如果按了yes再按no则减1,如果原来是no改成yes则次数加1,这个怎么实现,radio里的name和value我是下面这样定义的,代码片段如下:
Yes
No
Has your relative had accidents because of weakness, dizziness,
or inability to get around?
Has use of the stove, oven or appliances become a safety problem
because of forgetfulness?
Are there hazardous conditions in his/her home, such as the
bathroom and bedroom being on separate floors?
