給year和month添加一個ItemListener來實時計算指定年和月中有多少天就可以了.

代碼是用Swing寫的,不過看你的圖,不像是Swing界面.

/**

* Create the frame.

*/

public DateDropFrame() {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setBounds(100, 100, 450, 300);

contentPane = new JPanel();

contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));

contentPane.setLayout(new FlowLayout(FlowLayout.LEFT));

final JComboBox year = new JComboBox();

year.setModel(new DefaultComboBoxModel(getModel(start, end)));

contentPane.add(year);

final JComboBox month = new JComboBox();

month.setModel(new DefaultComboBoxModel(getModel(1, 12)));

contentPane.add(month);

final JComboBox day = new JComboBox();

contentPane.add(day);

year.addItemListener(new ItemListener() {

public void itemStateChanged(ItemEvent e) {

setDay(year, month, day);

}

});

month.addItemListener(new ItemListener() {

public void itemStateChanged(ItemEvent e) {

setDay(year, month, day);

}

});

setDay(year, month, day);

setContentPane(contentPane);

}

/**

* calculate days in select month year

*/

private void setDay(JComboBox year, JComboBox month, JComboBox day) {

int y = Integer.parseInt((String) year.getSelectedItem());

int m = Integer.parseInt((String) month.getSelectedItem());

Calendar c = Calendar.getInstance();

c.set(Calendar.YEAR, y);

c.set(Calendar.MONTH, m - 1);

int days = c.getActualMaximum(Calendar.DAY_OF_MONTH);

day.setModel(new DefaultComboBoxModel(getModel(1, days)));

}

/**

* get String array [start, end]

*/

private String[] getModel(int start, int end) {

String[] m = new String[end - start + 1];

for (int i = 0; i m.length; i++) {

m[i] = String.valueOf(i + start);

}

return m;

}

Java：求一個下拉列表是年月，點擊彈出需要當月的內(nèi)容

private?void??changeDayComboBox(String?dyear,String?dmouth){??

SimpleDateFormat?simpleDate?=?new?SimpleDateFormat("yyyy/MM");??

Calendar?rightNow?=?Calendar.getInstance();??

try{??

rightNow.setTime(simpleDate.parse(dyear+"/"+dmouth));??

}catch(ParseException?e){??

e.printStackTrace();??

}??

int?days?=?rightNow.getActualMaximum(Calendar.DAY_OF_MONTH);//根據(jù)年月?獲取月份天數(shù)??

DefaultComboBoxModel?list?=?new?DefaultComboBoxModel();??

for(int?i?=?0;?i??days;?i++){??

list.addElement(i+1);??

}??

m_DayComboBox.setModel(list);

調用

[java]?view plain?copy

changeDayComboBox("2015","7");

java swing里年份下拉框怎么寫

String[] arry = new String[201];

for (int i = 2000; i 2201; i++) {

arry[i-2000] = i+"年";

System.out.println(arry[i-2000]);

}

JComboBox combox = new JComboBox(arry);

java日期下拉框

你是要30天的日期嘛。。。

public String genRqOpts() {

StringBuilder rtn = new StringBuilder("");

java.util.Date date = new java.util.Date();//獲得當前系統(tǒng)時間

SimpleDateFormat simple = new SimpleDateFormat("yyyyMMdd");

String time = simple.format(date);

String cur_Y = time.substring(0,4);//年

String cur_M = time.substring(4,6);//月

String cur_D = time.substring(6,8);//日

Calendar calendar = Calendar.getInstance();//初始化對象

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

calendar.set(Integer.parseInt(cur_Y), Integer.parseInt(cur_M), Integer.parseInt(cur_D));

rtn.append("select");

for (int i=0;i30;i++) {//獲取頁面上下拉選項

calendar.add(Calendar.DATE, -1);

String elRq = sdf.format(calendar.getTime());

rtn.append("option value='");

rtn.append(elRq);

rtn.append("'");

rtn.append(elRq);

rtn.append("/option");

}

rtn.append("/select");

return rtn.toString();

}

java用在下拉框里添加日歷，記住一定用swing做的，怎么做啊，一點就彈出日歷那樣，好吧，求大神

將這個包解壓 ?將文件放到WebContent中 然后到jsp 導入

script type="text/javascript" src="/Rebates/My97DatePicker/WdatePicker.js"/script

這句代碼 ?由于 ?我的是WebContent下面還有個Rebates文件夾 所以路徑是這樣

使用的時候

input value="${startTime }" id="stime" name="startTime" onclick="WdatePicker({startDate:'%y-%M-01 10:00:00',dateFmt:'yyyy-MM-dd HH:mm:ss',alwaysUseStartDate:true})"

onclick事件 ? 就可以了
