## Plan
|
|
|
|
### Task 1: 后端新增接口
|
|
- File: `application/admin/controller/History.php` — 新增 `tailHeadProbability` 方法
|
|
- File: `application/admin/model/History.php` — 新增 `getTailHeadProbability` 方法
|
|
- 逻辑：查询全部历史数据（按 openTime 升序），逐期对比相邻两期的尾数和首位，统计相同概率
|
|
|
|
### Task 2: 前端添加工具栏按钮
|
|
- File: `application/admin/view/history/index.html` — 在工具栏添加"尾首概率"按钮
|
|
|
|
### Task 3: 前端弹窗逻辑
|
|
- File: `public/assets/js/backend/history.js` — 新增按钮点击事件 + `showTailHeadProbabilityDialog` 方法
