[摘要]以前用PHP时写了一个简单的class,功能主要是解决,大量页面上需要显示下拉列表框选择年/月/日/周之类的。希望对大家学习PHP和java能有帮助。php的实现如下:getCurrentDate.... 以前用PHP时写了一个简单的class,功能主要是解决,大量页面上需要显示下拉列表框选择年/月/日/周之类的。希望对大家学习PHP和java能有帮助。
php的实现如下: getCurrentDate.class.php <?php /* * 功能:生成下拉列表(年/月/日/周为当前值) * 程序员:xiangli * 日期:2003-01-19 */ #---------------------------------------------------# # 修改:2003-03-18# # 修改原因:添加了周的生成# #-------------------------------------------------#
class getCurrentDate{ var$Years = 2002; var$Months = 12; var$Days = 31; var$Weeks = 52;
/*获得年的下拉列表*/ function getCurrentYear() { for ($i = Date('Y'); $i >= $this->Years; $i--) { echo "<option value='$i'>{$i}年</option>\n"; } }
/*获得月的下拉列表*/ function getCurrentMonth() { for ($i = 1; $i <= $this->Months; $i++) { ($i<10)?($m="0".$i):($m=$i); if($i == date('m')) echo "<option value='$m' selected>{$m}月</option>\n"; else echo "<option value='$m'>{$m}月</option>\n"; } }
/*获得日的下拉列表*/ function getCurrentDay() { for ($i = 1; $i <= $this->Days; $i++){ if($i == date('d')) echo "<option value='$i' selected>{$i}日</option>\n"; else echo "<option value='$i'>{$i}日</option>\n"; } }
/*获得周的下拉列表*/ function getCurrentWeek() { for ($i = 1; $i <= $this->Weeks; $i++){ if($i == date('W')) echo "<option value='$i' selected>{$i}周</option>\n"; else echo "<option value='$i'>{$i}周</option>\n"; } } } ?>
调用如下: includ("../public/getCurrentDate.class.php"); $getCurrentDate = net getCurrentDate(); <select name ="xxxxx"> <?=$getCurrentDate->getCurrentYear()?> </select> //////////////////////////////////////////////////////////
java的实现方法: getCurrentDate.java /* * 功能:生成下拉列表(年/月/日/周为当前值) * 程序员:xiangli * 日期:2003-01-19 */ // #---------------------------------------------------# // # 修改:2003-03-18 # // # 修改原因:添加了周的生成 # // #-------------------------------------------------#

public class getCurrentDate { public int Years = 2002; public int Months = 12; public int Days = 31; public int Weeks = 52; Date myDate = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd w");
/*获得年的下拉列表*/ public String getCurrentYear() { String Content = ""; for (int i =Integer.parseInt(formatter.format(myDate).toString().substring(0, 4)); i >= Years; i--) { Content += "<option value='" + i + "'>" + i + "年</option>\n"; } return Content; }
/*获得月的下拉列表*/ public String getCurrentMonth() { String m; String Content = "";
for (int i = 1; i <= Months; i++) { m=i<10?("0" + i):Integer.toString(i); if(i == Integer.parseInt(formatter.format(myDate).toString().substring(5, 7))) Content += "<option value='" + m + "' selected>" + m + "月</option>\n"; else Content += "<option value='" + m + "'>" + m + "月</option>\n"; } return Content; }
/*获得日的下拉列表*/ public String getCurrentDay() { String Content = ""; String m;
for (int i = 1; i <= Days; i++){ m=i<10?("0" + i):Integer.toString(i); if(i == Integer.parseInt(formatter.format(myDate).toString().substring(8, 10))) Content += "<option value='" + m + "' selected>" + m + "日</option>\n"; else Content += "<option value='" + m + "'>" + m + "日</option>\n"; } return Content; }
/*获得周的下拉列表*/ public String getCurrentWeek() { String Content = ""; String m;
for (int i = 1; i <= Weeks; i++){ m=i<10?("0" + i):Integer.toString(i); if(i == Integer.parseInt(formatter.format(myDate).toString().substring(11))) Content += "<option value='" + m + "' selected>" + m + "周</option>\n"; else Content += "<option value='" + m + "'>" + m + "周</option>\n"; } return Content; } }
调用方法: <jsp:useBean id="getCurrentDate" scope="session" class="getCurrentDate" /> <select name="Years"> <%=getCurrentDate.getCurrentYear()%> </select> <select name="Months"> <%=getCurrentDate.getCurrentMonth()%> </select> <select name="Days"> <%=getCurrentDate.getCurrentDay()%> </select> <select name="Weeks"> <%=getCurrentDate.getCurrentWeek()%> </select> |
