小编教你datepickermode。

这段摘要描述了日期选择器模式。

DatePicker控件是一种常见的用户界面元素，用于选择日期，它通常以日历的形式显示，用户可以从中选择一个或多个日期，在许多编程语言和框架中，都有内置的DatePicker控件，如JavaScript、Java、.NET等，本文将介绍DatePicker控件的用法，包括基本用法、自定义样式、事件处理和跨浏览器兼容性等方面的内容。

1、基本用法

在不同的编程语言和框架中，DatePicker控件的基本用法略有不同，以下是一些常见编程语言和框架中的DatePicker控件的基本用法：

JavaScript（HTML5）：

<!DOCTYPE html>
<html>
<head>
<script>
function showDate() {
  document.getElementById("datepicker").style.display = "block";
}
</script>
</head>
<body>
<p>点击按钮显示日期选择器：</p>
<button onclick="showDate()">点击这里</button>
<input type="date" id="datepicker" style="display:none">
</body>
</html>

Java（Swing）：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class DatePickerDemo {
    public static void main(String[] args) {
        JFrame frame = new JFrame("DatePicker 示例");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 300);
        frame.setLayout(new FlowLayout());
        JTextField textField = new JTextField(20);
        JButton button = new JButton("选择日期");
        JPanel panel = new JPanel();
        panel.add(textField);
        panel.add(button);
        frame.add(panel);
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                JDatePickerImpl datePicker = new JDatePickerImpl(new DateLabelFormatter());
                datePicker.setSelectedDate(new Date());
                int result = JOptionPane.showConfirmDialog(null, datePicker, "选择日期", JOptionPane.OK_CANCEL_OPTION);
                if (result == JOptionPane.OK_OPTION) {
                    textField.setText(datePicker.getJFormattedTextField().getText());
                } else {
                    textField.setText("");
                }
            }
        });
        frame.setVisible(true);
    }
}
