## Overview

This is a WeChat mini-program for managing student leave requests. Users sign in by role; students can submit requests, while staff can review pending requests and accept or refuse them. Users can also browse requests by status or search by time, term, and reason, and students can save drafts locally for later editing. The excerpts show the login, submission, approval-detail, and time-search interactions; several other listed pages were not excerpted, so their internal behavior and connections are not asserted.

Main entry points: [`pages/index/index.js`](https://github.com/jiananyou/leavemanager_wechat/blob/master/pages/index/index.js) (Request dashboard), [`pages/common/vacate/vacate.js`](https://github.com/jiananyou/leavemanager_wechat/blob/master/pages/common/vacate/vacate.js) (Submit leave), [`pages/common/findbytime/findbytime.js`](https://github.com/jiananyou/leavemanager_wechat/blob/master/pages/common/findbytime/findbytime.js) (Time search), [`pages/search/search.js`](https://github.com/jiananyou/leavemanager_wechat/blob/master/pages/search/search.js) (Search options)
