这次给大家带来JS里特别好用的轻量级日期插件,使用JS里特别好用轻量级日期插件的注意事项有哪些,下面就是实战案例,一起来看一下。
jquery的日期插件有好几款,H5中的input也可以自带日期选择。但为什么要再写一个,有两个理由,一个是引用的文件太大,而有时候只需要很简单的功能,二个是想加一些自定义的效果不好改。
我写的这个功能比较简单,可以换月,有预约效果,可以设定预约日期范围,压缩后1.4kb,先上个图,再慢慢解释:
js代码:
$.fn.datebox = function (options) { var config = { $valueEle: $("#outputTime"), $prev: $(".datetitle #up"), $next: $(".datetitle #down"), minDate:null, maxDate:null, } config = $.extend(config, options); Date.prototype.format = function (format) { var o = { "M+": this.getMonth() + 1, //month "d+": this.getDate(), //day "h+": this.getHours(), //hour "m+": this.getMinutes(), //minute "s+": this.getSeconds(), //second "q+": Math.floor((this.getMonth() + 3) / 3), //quarter "S": this.getMilliseconds() //millisecond } if (/(y+)/.test(format)) format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length)); for (var k in o) if (new RegExp("(" + k + ")").test(format)) format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length)); return format; }; var self = this; var $ele = $(this); var maxdate,mindate; var nstr = new Date(); var ynow = nstr.getFullYear(); var mnow = nstr.getMonth(); var dnow = nstr.getDate(); if(!config.minDate){ mindate=nstr; }else{ mindate=new Date(config.mindate) } if(config.maxDate){ maxdate=new Date(config.maxDate) } self.isLeap = function (year) { return (year % 100 == 0 ? res = (year % 400 == 0 ? 1 : 0) : res = (year % 4 == 0 ? 1 : 0)); } console.log("最小日期是:",mindate.format("yyyy-MM-dd")) console.log("最大日期是:",maxdate.format("yyyy-MM-dd")) console.log("当前日期:",currentDate()) pain(); function pain() { var n1str = new Date(ynow, mnow, 1); //当月第一天 var firstday = n1str.getDay(); //当月第一天星期几 var m_days = new Array(31, 28 + self.isLeap(ynow), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31); //各月份的总天数 var tr_str = Math.ceil((m_days[mnow] + firstday) / 7); //表格所需要行数 //打印表格第一行(有星期标志) $("#datetb").remove(); var str = "<table id='datetb' cellspacing='0'><tr><td>周日</td><td>周一</td><td>周二</td><td>周三</td><td>周四</td><td>周五</td><td>周六</td></tr>"; for (i = 0; i < tr_str; i++) { //表格的行 str += "<tr>"; for (k = 0; k < 7; k++) { //表格每行的单元格 idx = i * 7 + k; //单元格自然序列号 date_str = idx - firstday + 1; //计算日期 (date_str <= 0 || date_str > m_days[mnow]) ? date_str = " " : date_str = idx - firstday + 1; //过滤无效日期(小于等于零的、大于月总天数的) //打印日期:今天底色样式 date_str == dnow ? str += "<td class='selected' data-day=" + date_str + ">" + "<p>" + date_str + "</p>" + "<p class='subscribe'>预约</p>" + "</td>" : str += "<td data-day=" + date_str + ">" + date_str + "</td>"; } str += "</tr>"; //表格的行结束 } str += "<tfoot><tr><td colspan='7'>" + ynow + "年" + (mnow + 1) + "月</td></tr></tfoot>"; str += "</table>"; //表格结束 $ele.html(str); setDate(ynow, mnow, dnow); } function setDate(y, m, d) { var current = (new Date(y, m, d, 10, 0, 0)).format("yyyy-MM-dd"); console.log(y, m, d, current); config.$valueEle.val(current); } function currentDate(){ return (new Date(ynow, mnow, dnow, 10, 0, 0)).format("yyyy-MM-dd"); } self.prev=function(){ var temp = mnow - 1; if (temp < 0) { mnow = 11; ynow--; } else { var prevdate=new Date(ynow, mnow-1, 31, 10, 0, 0); if (prevdate <mindate) { console.log("超过最小可预约日期",prevdate.format("yyyy-MM-dd")) return; } mnow--; } if(ynow==mindate.getFullYear()&&mnow==mindate.getMonth()){ var _mday=mindate.getDate(); if(dnow<_mday) dnow=_mday; } pain(); } self.next=function(){ var nextdate=new Date(ynow, mnow+1, 1, 10, 0, 0); if (nextdate>maxdate) { console.log("超过最大可预约日期",nextdate.format("yyyy-MM-dd")) return ; } var temp = mnow + 1; if (temp > 11) { mnow = 0; ynow++; } else { mnow++; } if(ynow==maxdate.getFullYear()&&mnow==maxdate.getMonth()){ var _mday=maxdate.getDate(); if(dnow>_mday) dnow=_mday; } pain(); } self.seleted=function($td){ if (!$td.hasClass('selected')) { var day = $td.data("day"); var selectedDate=new Date(ynow, mnow, day, 1, 0, 0); if (selectedDate<mindate||selectedDate>maxdate) { console.log("该日期不能预约"); return; } $(".datebox table td").removeClass('selected').children('.subscribe').remove(); $td.addClass('selected'); $td.html('<p>' + $td.html() + '</p><p class="subscribe">预约</p>'); dnow=day; setDate(ynow, mnow, day); } } self.getDate=function(){ return currentDate(); } $ele.on("click", "table td", function () { self.seleted($(this)); }); config.$prev.click(function () { self.prev(); }); config.$next.click(function () { self.next(); }); return self; }
css:随便玩了。

公布了isLeap,next,prev,getdate,seleted 五个方法(看名字就不需要解释了吧)。默认今天是最小的预约时间。
可以这样设定最大的可预约时间:
var date = $(".datebox").datebox({maxDate:"2016-12-20"});
同理可以设置最小日期。
换月的时候日期会自动切换到可预约的日期。
