JQuery教程实例-年月日的级联菜单

1， 首先构建该JQuery教程实例中的index.html文件。代码如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>JQuery实例 - 生成年月日</title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
        <script type="text/javascript" src="calender.js"></script>
    </head>
    <body>
        <div align="center" style="margin-top:200px;">
            <form name="form1" method="post" action="">
                <select name="year">
                </select>年
                <select name="month">
                </select>月
                <select name="day">
                </select>日
            </form>
        </div>
    </body>
</html>

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 + "<option value='"+i+"' selected>"+i+"</option>";
        }else{
            dropList = dropList + "<option value='"+i+"'>"+i+"</option>";
        }
    }
    $('select[name=year]').html(dropList);//生成年份下拉菜单
    var monthly;
    for(month=1;month<13;month++){
        monthly = monthly + "<option value='"+month+"'>"+month+"</option>";
    }
    $('select[name=month]').html(monthly);//生成月份下拉菜单
    var dayly;
    for(day=1;day<=31;day++){
        dayly = dayly + "<option value='"+day+"'>"+day+"</option>";
    }
    $('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 + "<option value='"+day+"'>"+day+"</option>";
        }
        $('select[name=day]').html(currentDay);//生成日期下拉菜单
        })
})
