请自查，或者提供最简复现demo。你这大堆业务代码没时间给你看

你离开了这个页面了，然后setinterval 还在跑，然后期望把弹窗弹出来？

你好，请具体描述问题出现的流程，并提供能复现问题的简单代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）。

不是，我又进入这个页面了，我的意思是我离开后又进来了，条件满足没弹窗，我console输出的true，在前台显示下是false

麻烦帮我看看，console输出true，但是前台还是false，快改一天了都

复现很难啊，涉及到数据库什么的，就是我用wx:if做了个弹窗，在一个轮询中查数据库的状态，第一次加载时数据库条件满足时，wx:if变为true，弹窗出现，离开当前页面再进来，轮询还在接着之前的继续，条件再次满足时，设为true但是弹窗不出现，我在前台显示下，显示的是false，给你截下那个轮训的代码
