在前端开发制作中，我们经常用到的一个功能，就是jQuery日期联动效果，本jQuery日期联动插件支持选择年月日，并且可以设置最大年份，选择对应的月数后，则对应日期。附带demo和下载，希望你有所收获。
/* * jQuery Date Selector Plugin * 日期联动选择插件 * * Demo: $("#calendar").DateSelector({ ctlYearId: <年控件id>, ctlMonthId: <月控件id>, ctlDayId: <日控件id>, defYear: <默认年>, defMonth: <默认月>, defDay: <默认日>, minYear: <最小年|默认为1882年>, maxYear: <最大年|默认为本年> }); HTML:<div id="calendar"><SELECT id=idYear></SELECT>年 <SELECT id=idMonth></SELECT>月 <SELECT id=idDay></SELECT>日</div> */ (function ($) { //SELECT控件设置函数 function setSelectControl(oSelect, iStart, iLength, iIndex) { oSelect.empty(); for (var i = 0; i < iLength; i++) { if ((parseInt(iStart) + i) == iIndex) oSelect.append("<option selected='selected' value='" + (parseInt(iStart) + i) + "'>" + (parseInt(iStart) + i) + "</option>"); else oSelect.append("<option value='" + (parseInt(iStart) + i) + "'>" + (parseInt(iStart) + i) + "</option>"); } } $.fn.DateSelector = function (options) { options = options || {}; //初始化 this._options = { ctlYearId: null, ctlMonthId: null, ctlDayId: null, defYear: 0, defMonth: 0, defDay: 0, minYear: 1882, maxYear: new Date().getFullYear() } for (var property in options) { this._options[property] = options[property]; } this.yearValueId = $("#" + this._options.ctlYearId); this.monthValueId = $("#" + this._options.ctlMonthId); this.dayValueId = $("#" + this._options.ctlDayId); var dt = new Date(), iMonth = parseInt(this.monthValueId.attr("data") || this._options.defMonth), iDay = parseInt(this.dayValueId.attr("data") || this._options.defDay), iMinYear = parseInt(this._options.minYear), iMaxYear = parseInt(this._options.maxYear); this.Year = parseInt(this.yearValueId.attr("data") || this._options.defYear) || dt.getFullYear(); this.Month = 1 <= iMonth && iMonth <= 12 ? iMonth : dt.getMonth() + 1; this.Day = iDay > 0 ? iDay : dt.getDate(); this.minYear = iMinYear && iMinYear < this.Year ? iMinYear : this.Year; this.maxYear = iMaxYear && iMaxYear > this.Year ? iMaxYear : this.Year; //初始化控件 //设置年 setSelectControl(this.yearValueId, this.minYear, this.maxYear - this.minYear + 1, this.Year); //设置月 setSelectControl(this.monthValueId, 1, 12, this.Month); //设置日 var daysInMonth = new Date(this.Year, this.Month, 0).getDate(); //获取指定年月的当月天数[new Date(year, month, 0).getDate()] if (this.Day > daysInMonth) { this.Day = daysInMonth; }; setSelectControl(this.dayValueId, 1, daysInMonth, this.Day); var oThis = this; //绑定控件事件 this.yearValueId.change(function () { oThis.Year = $(this).val(); setSelectControl(oThis.monthValueId, 1, 12, oThis.Month); oThis.monthValueId.change(); }); this.monthValueId.change(function () { oThis.Month = $(this).val(); var daysInMonth = new Date(oThis.Year, oThis.Month, 0).getDate(); if (oThis.Day > daysInMonth) { oThis.Day = daysInMonth; }; setSelectControl(oThis.dayValueId, 1, daysInMonth, oThis.Day); }); this.dayValueId.change(function () { oThis.Day = $(this).val(); }); } })(jQuery);
