1， 首先构建该JQuery教程实例中的index.html文件。代码如下：
JQuery实例 - 生成年月日
2、Calender.js文件：
$('document').ready(function(){ /* * 生成级联菜单 */ var i=1945; var date = new Date(); year = date.getFullYear();//获取当前年份 var dropList; for(i;i<2012;i++){ if(i == year){ dropList = dropList + ""; }else{ dropList = dropList + ""; } } $('select[name=year]').html(dropList);//生成年份下拉菜单 var monthly; for(month=1;month<13;month++){ monthly = monthly + ""; } $('select[name=month]').html(monthly);//生成月份下拉菜单 var dayly; for(day=1;day<=31;day++){ dayly = dayly + ""; } $('select[name=day]').html(dayly);//生成天数下拉菜单 /* * 处理每个月有多少天---联动 */ $('select[name=month]').change(function(){ var currentDay; var Flag = $('select[name=year]').val(); var currentMonth = $('select[name=month]').val(); switch(currentMonth){ case "1" : case "3" : case "5" : case "7" : case "8" : case "10" : case "12" :total = 31;break; case "4" : case "6" : case "9" : case "11" :total = 30;break; case "2" : if((Flag%4 == 0 && Flag%100 != 0) || Flag%400 == 0){ total = 29; }else{ total = 28; } default:break; } for(day=1;day <= total;day++){ currentDay = currentDay + ""; } $('select[name=day]').html(currentDay);//生成日期下拉菜单 })}) 原文地址：http://www.phpfuns.com/scripts/jquery/jquery-calender-examples.shtml
