一个users是一个数据,我想按users的记录数作为序号,怎么实现
付费偷看金额在0.1-10元之间

但是这个地方题主是不是想根据users的数量进行编号,不知道我理解的对不对,这样子我的建议是在最外层init一个变量,最里层的v-for每次++。
1.x (userIndex , userInfo) in list.users 索引在前
显示声明index:
v-for="(userInfo , userIndex) in list.users"
2.x (userInfo , userIndex) in list.users 值在前,并且$index已废弃
另外也可以为数组索引指定别名(如果值是对象可以为键指定别名):
这个可以解决父子之间的索引问题,不至于混乱,当然是题外话。
