使用 HTML + JavaScript 实现单会议室周日历管理系统

效果演示

该系统通过日历视图的形式展示单个会议室在一周内的使用情况。用户可以选择特定会议室并查看其在本周的预订状态，还能申请新的会议，删除已有会议。系统采用颜色编码来区分不同的会议状态，使用户能够快速识别会议室的可用性。

页面结构

系统主要包括以下几个功能区域：

控制面板区域

控制面板位于页面顶部，提供会议室选择和基本操作按钮。用户可以通过下拉菜单选择要查看的会议室。

<div class="form">
<select id="roomSel">
<option value="">选择会议室</option>
</select>
<button onclick="search()">查询</button>
<button onclick="openApplyModal()">申请会议</button>
</div>

历展示区域

这是系统的核心展示区域，以表格形式呈现选定会议室在一周内每天的使用情况。

<div id="calendar" class="calendar"></div>

核心功能实现

日历渲染

日历渲染是系统最核心的功能，通过 renderCal 函数实现。该函数负责将会议数据转换为可视化的日历表格：

创建表头行，显示星期和日期信息

为每个时间槽创建一行，显示该时段在每天的会议情况

根据会议持续时间合并单元格，正确显示跨时段的会议

function renderCal(map, days) {
var box = document.getElementById('calendar');
box.innerHTML = '';

var hRow = document.createElement('div');
hRow.className = 'row';
// 使用新的日期格式显示
hRow.innerHTML = '<div class="cell cell-time">时间</div>' +
days.map(d => `<div class="cell cell-time">${d.day}</div>`).join('');
box.appendChild(hRow);

for(var i = 0; i < timeArr.length - 1; i++) {
var row = document.createElement('div');
row.className = 'row';

var html = `<div class="cell">${timeArr[i]} ~ ${timeArr[i+1]}</div>`;

days.forEach(d => {
var key = `${d.date}#${timeArr[i]}`;
if(map[key]) {
var m = map[key];
var colorClass = {1:'yellow', 3:'blue', 4:'pink', 5:'gray'}[m.status];

// 计算会议跨越的单元格数量
var startIndex = timeArr.indexOf(m.start);
var span = m.time;

// 只在会议开始时间渲染会议元素
if (startIndex === i) {
// 计算宽度：跨越的单元格数 * 100% + 边框宽度
var height = `calc(${span * 100}% + ${(span - 1) * 2}px)`;

html += `<div class="cell">
<div class="meeting-container">
<div class="meeting ${colorClass}"
style="width:100%;height: ${height}"
onclick="showMeetingDetail(event, '${m.id}', '${m.date}')">
${m.title}
${m.isCreator === 'true' && [1, 3].includes(m.status) ?
`<button class="close-btn" onclick="delMeet(event,'${m.id}', '${m.date}', '${m.room}')">×</button>` : ''}
</div>
</div>
</div>`;
} else if (i > startIndex && i < startIndex + span) {
// 对于被会议跨越的中间单元格，保持空单元格
html += '<div class="cell"></div>';
} else {
html += '<div class="cell"></div>';
}
} else {
html += '<div class="cell"></div>';
}
});

row.innerHTML = html;
box.appendChild(row);
}
}
