【问题描述】:
我正在使用 Vue.js 创建一个包含多个页面的调查。一切正常,除了我需要使浏览器后退/前进按钮与页面上的上一个/下一个按钮相同。
我用谷歌搜索了很多次,但我暂时想不出任何解决方案......
我知道我可以使用vue-router,但我不知道如何适应它。
我怎样才能做到这一点?

【问题讨论】:
-
这不是你的答案,但我认为这可能是一个问题:在函数内定义调查不会让它具有全局范围,对吗?我认为您需要将
new Vue({...})代码放在 onload 处理程序中。 -
@RobertMoore,感谢您的评论。页面本身工作得很好,唯一的问题是浏览器的后退按钮不会返回到上一个问题(例如),而是返回到浏览器之前打开的页面。所以你认为你的想法可以解决这个问题?我会试一试,然后回复你
