年月日日历选择组件

时间:2024-03-17 19:48:31

功能:年月日日历选择插件,可指定显示日期。

目的:仅为项目需要,所以封装为一个组件,同时也作为对工作的日常记录,用以以后复用。

1.html简单代码:

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>年月日插件</title>
</head>

<body>
<div class="ymdCalendar">
    <select class="year" name="year"></select>
    <select class="month" name="month"></select>
    <select class="day" name="day"></select>
</div>
</body>
</html>
 
 
2.以下为jquery完整代码:
<script>

;(function($){
    $.fn.ymdCalendar = function (options) {
        var defaults = {
                Yclass: \'.year\', // 默认年份选择器
                Mclass: \'.month\',// 默认月份选择器
                Dclass: \'.day\',  // 默认日选择器
                  Year: \'\',      // 默认年
                 Month: \'\',      // 默认月
                   Day: \'\'       // 默认日
            };
        var opts = $.extend({}, defaults, options);
        var DateTime = new Date();
        var nowY = opts.Year || DateTime.getFullYear();
        var nowM = opts.Month || DateTime.getMonth()+1;
        var nowD = opts.Day || DateTime.getDate();
        var days = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];
        return this.each(function(){
            
            // 年月日选择器
            var Y = $(this).find(opts.Yclass);
            var M = $(this).find(opts.Mclass);

            // 默认选中当天
            if (isRun(nowY)) days[1] = 29;
            Y.html(tcFn(nowY-30, nowY+30, nowY));// 设置年份,前后30年
            M.html(tcFn(1, 12, nowM));// 设置月份
            D.html(tcFn(1, days[nowM-1], nowD));// 设置天
            
            // 年份改变日期改变
            Y.change(function(){
                isRun($(this).val()) ? days[1] = 29 : days[1] = 28;
                console.log(days)
                D.html(tcFn(1, days[M.val()-1], $(this).val()));
            })
            
            // 月份改变日期改变
            M.change(function(){

        }
    };
})(jQuery)


$(function () {

             Year: 2007,
            Month: 8,
              Day: 8
        });
    
})
</script>

若有幸被您看到,并发现有问题,可留言,楼主看到尽快修改。

3.更新2016-11-07

由于项目需要,该些时间必须在指定范围内可选则,比如从过去10个月至今日,这个时间点才可选择,因此优化为下(一下为完整代码):

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>年月日插件</title>
</head>

<body>
<div class="ymdCalendar1">
    <select class="year" name="year"></select>
    <select class="month" name="month"></select>
    <select class="day" name="day"></select>
</div>
<div class="ymdCalendar2">
    <select class="year" name="year"></select>
    <select class="month" name="month"></select>
    <select class="day" name="day"></select>
</div>
<div class="ymdCalendar3">
    <select class="year" name="year"></select>
    <select class="month" name="month"></select>
    <select class="day" name="day"></select>
</div>
<!--<div class="ymdCalendar" id="ymdCalendar">
