技术栈：React、antd
一 需求背景
使用周视图来显示广播信息与状态
二 组件特点
- 当多个时间块交叠时，并行显示。对于交叠时间块，最多显示3个，如果要显示全部交叠的时间块，可点击展开。
- 可对时间段精度进行扩展。当有多个时间段短的时间块相邻但不重叠时，方便看查。
- 支持跨天显示。对于跨天的广播，会将其分割。假设该广播跨了3天，那么就会根据日期分割成3个时间块，单独填充到对应的日期。
- 支持点击回到本周。

四 实现过程
4.1 数据转换
本示例的原始数据如下：
json
{
"code": 0,
"description": "成功",
"data": {
"list": [{
"ebmid": "24300000000000103010101202409240001",
"name": "1122222",
"status": "3",
"start_time": "2024-09-24 16:30:39",
"end_time": "2024-09-24 16:34:32",
"msg_type": "1",
"covered_regions": "常德市",
"creator": "省平台"
}]
}
}最后渲染到组件的数据如下，省略了一些无关属性方便理解：
javascript
{
"2024-09-24": [Array<TimeBlock>]
}该转换过程给原始元素加了splited_start_time、splited_end_time、key三个属性，后者用于标识时间块的唯一性。
一般情况下，日期对应的值是单个时间块元素就可以了。但是因为存在时间段重叠的原因，就对元素进行了二次分组，将时间重叠的时间块分为一组。
json
{
"2024-09-24": [
[
{
"start_time": "2024-09-24 16:30:39",
"end_time": "2024-09-24 16:34:32",
"splited_start_time": "2024-09-24 16:30:39",
"splited_end_time": "2024-09-24 16:34:32",
"key": "4FFXJ2CG"
}
]
],
"2024-09-26": [
[
{
"start_time": "2024-09-26 01:16:09",
"end_time": "2024-09-26 02:20:02",
"splited_start_time": "2024-09-26 01:16:09",
"splited_end_time": "2024-09-26 02:20:02",
"key": "3RQOUQV1"
}
],
[
{
"start_time": "2024-09-26 03:07:22",
"end_time": "2024-09-26 12:11:15",
"splited_start_time": "2024-09-26 03:07:22",
"splited_end_time": "2024-09-26 12:11:15",
"key": "NAOO8UZD"
},
{
"start_time": "2024-09-26 04:17:15",
"end_time": "2024-09-26 13:21:08",
"splited_start_time": "2024-09-26 04:17:15",
"splited_end_time": "2024-09-26 13:21:08",
"key": "RI8IT06L"
},
{
"start_time": "2024-09-26 11:13:35",
"end_time": "2024-09-26 14:15:12",
"splited_start_time": "2024-09-26 11:13:35",
"splited_end_time": "2024-09-26 14:15:12",
"key": "P17N84F0"
}
]
]
}数据转换思路：
- 首先将原始数据进行分割（针对跨天的情况），当元素跨3天，就分割成3个元素
- 对分割后的元素基于开始时间进行从早到晚排序
- 对排序后的元素进行按天分组
- 对按天分组内的元素进行二次分组，将时间段重叠的单独分成一组
4.2 组件文件结构
diff
- index.js
- useWeek.js // 控制周切换相关方法
- Controler.js // 控制周切换
- TimeBlock.js // 时间块子组件
- Detail.js // 广播详情展示
- ColorTags.js // 颜色图标提示
- utils.js // 通用方法
- useExpandTime.js
- style.less是有更优化的结构的，但是实现了就懒得优化了。
