尝试执行上述代码时，出现以下错误：TypeError：document.form1 [nominatefriend [i]]。已选中。 我正在使用nominatefriend [i]迭代所有选项，但这对我没有任何意义。
答案 0 :(得分：1)
你声明一个这样的变量，所以它是一个数字（整数）
var nominatefriend = qNum+j;
然而，您可以像数组一样访问它：
document.form1[nominatefriend[i]].selected
对于二维数组，您需要
document.form1[nominatefriend][i].selected
但是，还要注意评论，特别是关于文档中重复ID的评论。
