如何将链接附加到单个数组项目？

我一直在努力工作数小时，试图让这个工作。我想要做的是：首先，有两个下拉菜单，第一个控制第二个。然后，我希望能够将每个单独的“第二选择”链接到href。但是，“第二选择”在一个数组中，我不知道如何将它们访问到html中。请帮忙。如何将链接附加到单个数组项目？

如果我理解正确的话，你要根据以往的下拉选项来显示第二个下拉？检查这个答案：[链接]（http://stackoverflow.com/questions/6954556/show-a-second-dropdown-based-on-previous-dropdown-选择） – WhatisSober
