Javascript 无法从函数访问数组
我现在正在创建一个有2个问题的测验网站。用户将获得一个问题和单选按钮来选择答案。用户选择的任何内容都将存储在cookie中，稍后将提供给php进行数据库检索。status数组用于检查是否选中了第一个选项或第二个选项。当我选择“上一个”按钮时，会显示上一个问题，但单选按钮不会改变，即它将与第二个问题相同Javascript 无法从函数访问数组,javascript,Javascript,我现在正在创建一个有2个问题的测验网站。用户将获得一个问题和单选按钮来选择答案。用户选择的任何内容都将存储在cookie中，稍后将提供给php进行数据库检索。status数组用于检查是否选中了第一个选项或第二个选项。当我选择“上一个”按钮时，会显示上一个问题，但单选按钮不会改变，即它将与第二个问题相同 <html> <head> <script> var count = 1; var status = new Arra
