javascript - 请问这个微信小程序 这种进度条 怎么做呢？有个菜单，下面有个当前价跟随走动，或者哪个小程序ui框架能做呢？

Question

Answer 1

虽然我没有做过微信小程序，但是我觉得你可能要找的是滑动条（range）。

比如这些：

• https://developers.weixin.qq.com/miniprogram/dev/component/sl...
• http://mint-ui.github.io/docs/#/zh-cn2/range
• https://vant-contrib.gitee.io/vant-weapp/0.x/#/slider
• https://taro-docs.jd.com/docs/components/forms/slider

Answer 2

可以看看vant-weapp、minui，然后改造一下
这篇文章也有实现：https://blog.csdn.net/m0_46735106/article/details/122541277
