JavaScript日历是一种用于显示日期和时间的用户界面组件。它通常包括月份的视图,显示该月的所有日期,并允许用户导航到不同的月份或年份。日历可以用于选择日期、显示事件或日程安排等。
以下是一个简单的JavaScript日历示例,使用HTML、CSS和JavaScript实现:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>JavaScript Calendar</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div id="calendar"></div>
<script src="calendar.js"></script>
</body>
</html>
#calendar {
width: 300px;
margin: 0 auto;
font-family: Arial, sans-serif;
}
.header {
display: flex;
justify-content: space-between;
align-items: center;
margin-bottom: 10px;
}
.days {
display: grid;
grid-template-columns: repeat(7, 1fr);
gap: 5px;
}
.day {
padding: 5px;
text-align: center;
border: 1px solid #ccc;
}
function generateCalendar(year, month) {
const calendarDiv = document.getElementById('calendar');
const daysInMonth = new Date(year, month + 1, 0).getDate();
const firstDay = new Date(year, month, 1).getDay();
calendarDiv.innerHTML = `
<div class="header">
<button onclick="prevMonth()">Prev</button>
<h2>${new Date(year, month).toLocaleString('default', { month: 'long', year: 'numeric' })}</h2>
<button onclick="nextMonth()">Next</button>
</div>
<div class="days">
${Array.from({ length: firstDay }, () => '<div class="day"></div>').join('')}
${Array.from({ length: daysInMonth }, (_, i) => `<div class="day">${i + 1}</div>`).join('')}
</div>
`;
}
function prevMonth() {
const currentDate = new Date(document.querySelector('.header h2').textContent);
generateCalendar(currentDate.getFullYear(), currentDate.getMonth() - 1);
}
function nextMonth() {
const currentDate = new Date(document.querySelector('.header h2').textContent);
generateCalendar(currentDate.getFullYear(), currentDate.getMonth() + 1);
}
// Initialize calendar with current month
generateCalendar(new Date().getFullYear(), new Date().getMonth());
通过以上步骤,您可以创建一个基本的JavaScript日历,并解决常见的实现问题。
