js,日历控件很少发现网上有简洁好用的自定义前端控件的贴子，最近项目中需要，自己YY开始写前端控件，在此给大家分享 控件是基于jQuery.UI的Widget写的，写起来就方便很多，使用起来跟普通jQuery控件一样$(#id).control(option)，看着眼熟吧，下面就开始了。 首先说下控件的依赖包，加载控件的时候必须先加载jQuery, jQuqery.UI, 另外jquery-ui.css 这个包也需要引用，此包主要应用了jQuery拖拽和放缩的样式，控件样式方面大家自由发挥，给了个自己写的默认样式包 (献丑了)。 控件本身支持颜色自定义，可根据日期自定义日历上某日的颜色，另外可悬浮，拖拽，自由变形算是卖点吧，哈哈 控件包加载是这样的： <link href="../../Content/themes/base/jquery-ui.css" rel="external nofollow" rel="stylesheet" /><link href="../../Content/datePrinter.css" rel="external nofollow" rel="stylesheet" /><script src="../../Scripts/default/jquery-ui-1.8.20.min.js"></script><script src="../../Scripts/control/datePrinter.js"></script> 控件中的核心部分就是打印选中月的日历，是参考网上的代码，偷懒嘛，欢迎认领 例如页面代码如下： <input type="text" id="datepickerInput"/>
调用的写法： var dpCon = $("#datepickerInput").datePrinter({ initDate: "2017-4-5", //初始化日期 language: "EN", //语言 resizable: true, //可自由变形 draggable: true, //可悬浮拖拽 showYearAndMonth: true, //是否显示年月下拉框 getColor: getColor, //自定义颜色接口 chooseDone: chooseDone //选中日历某日执行事件接口 }); //选中日期时让日历消失 当然此处可以执行比较复杂的业务，如服务器数据请求 function chooseDone(date) { dpCon.datePrinter("dpHide"); } //自定义日期颜色 function getColor(day){ if(day == 3 || day==7 || day==15) return "dpdisabled"; else if(day== 5 || day==18 || day==23) return "dpyellow"; else return "dpenable"; } //获取当前选中的日期 调用控件提供的API getSelectDate dpCon.datePrinter("getSelectDate");这样子就给上面的input text控件注册了一个日历控件，在点击input时，日历就会浮出，效果如下  你可能注意到右下角的小三角了，鼠标放上去之后可以随意变化日历的长宽，另外在日历上按住鼠标左键可以随意移动日期控件的位置，不挤占页面位置 
下面这段是打印日历的代码，供参考： //默认获取当前日期 var today = option.initDate ? option.initDate : new Date(); this.options.initDate = today; //获取日期中的年份 var y = today.getFullYear(), //获取日期中的月份(需要注意的是：月份是从0开始计算，获取的值比正常月份的值少1) m = today.getMonth(), //获取日期中的日(方便在建立日期表格时高亮显示当天) d = today.getDate(), //获取当月的第一天 firstday = new Date(y, m, 1), //判断第一天是星期几(返回[0-6]中的一个，0代表星期天，1代表星期一，以此类推) dayOfWeek = firstday.getDay() == 0 ? 7 : firstday.getDay(), //创建月份数组 days_per_month = new Array(31, 28 + self._isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //确定日期表格所需的行数 str_nums = Math.ceil((dayOfWeek + days_per_month[m] - 1) / 7); //二维数组创建日期表格 for (i = 0; i < str_nums; i += 1) { var tr = '<tr>'; for (k = 0; k < 7; k++) { //为每个表格创建索引,从0开始 var idx = 7 * i + k; //将当月的1号与星期进行匹配 var day = idx - dayOfWeek +2; var styleName = self._getColor(day); if (option.getColor && typeof (option.getColor) == 'function') styleName = option.getColor(day); styleName += " dateTD"; (day <= 0 || day > days_per_month[m]) ? //索引小于等于0或者大于月份最大值就用空表格代替 (day = ' ', styleName = "dpBlank") : (day = idx - dayOfWeek + 2); day == d ? tr += '<td class="' + styleName + ' today">' + day + '</td>' : //高亮显示当天 tr += '<td class="' + styleName + '">' + day + '</td>'; } tr += '</tr>'; self._dpTable.append(tr); tr = ""; }以前都是写后台，玩前端的时间不长，有不对的地方欢迎指正 datePrinter.js的全部代码如下： var _datePrinter_tmpl_CN = "<tr><th>一</th><th>二</th><th>三</th><th>四</th><th>五</th><th>六</th><th>日</th></tr>";var _datePrinter_tmpl_EN = "<tr><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th><th>Sat</th><th>Sun</th></tr>";Date.prototype.Format = function (fmt) { //author: meizz var o = { "M+": this.getMonth() + 1, //月份 "d+": this.getDate(), //日 "h+": this.getHours(), //小时 "m+": this.getMinutes(), //分 "s+": this.getSeconds(), //秒 "q+": Math.floor((this.getMonth() + 3) / 3), //季度 "S": this.getMilliseconds() //毫秒 }; if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length)); for (var k in o) if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ?
