jQuery实现可以扩展的日历
(编辑:jimmy 日期: 2024/11/1 浏览:3 次 )
新的产品需求需要,要写一个这样的日历插件。
效果图如下:
选择日期后,显示当前可以选择的时间,时间的列表是通过ajax从后台获取的一组数据。
而且这个日期存在的情况,还是动态渲染的一个列表里面,再动态渲染的一个日历。
例如:
此时的步骤图渲染是根据后台给的一个list来渲染的,所以,里面的元素但凡要点击,要交互,就要注意事件冒泡。
bootstrap的日历插件,运用起来也没法满足需求,所以被迫自己写了一个日历
代码如下:
var date = new Date() var nowYear = date.getFullYear(); //获取当前年份 var nowMonth = date.getMonth() + 1; //获取当前月份 var nowDay = date.getDate(); //获取当前天 var splitString = "-"; //年月日之间的分隔符 var weekDays = new Array("日", "一", "二", "三", "四", "五", "六"); //星期数组 var months = new Array("一月", "二月", "三月", "四月", "五月", "六月", "七月", "八月", "九月", "十月", "十一月", "十二月"); //月份数组 var lastDays = new Array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31); //每个月的最后一天是几号 //变量保存,存储当前选择的年月 var checkYear = nowYear; var checkMonth = nowMonth; // //将选择的日期添加到输入框 function setInput(selectDay) { $('#txt_calendar').value = checkYear + splitString + checkMonth + splitString + selectDay; hidDate(); } // //显示控件 function showDate() { createDate(nowYear, nowMonth);//创建日历 console.log(nowYear, nowMonth, '创建时间日历') //计算显示控件位置 ///获取当前输入框的位置,在实际操作中需要修改此处ID var x = $('#txt_calendar').offset().left var y = $('#txt_calendar').offset().top + 22 console.log(x, y, 'x, y', $('#txt_calendar')) $('#testID').css({ left: '-38px', top: '37px' }) } // /* // * 以下拼接日历框 // * 并定位日历框 // * */ // //创建日历样式 function createDate(thisYear, thisMonth) { console.log(thisYear, thisMonth, '创建日历------------------') var createDoc = '<div style="height: 30px;">'; //当前年月日,点击此处日历自动跳到当前日期 createDoc += '<p style="width: 100%;height: 30px;text-align: center;color: #999; display: none;" onclick="getThisDay()">当前日期 ' + nowYear + "年" + nowMonth + "月" + nowDay + "号"; //关闭日历显示 createDoc += '<span id="closeDate" onClick="hidDate()" style="float: right;font-size: 25px;margin: -20px 3px 0 0;cursor: pointer;">×</span></p></div>';; createDoc += '<div style="margin-bottom: 8px;">'; // 上月 createDoc += '<span id="lastMonth" style="margin: 0 20px 0 25px;cursor:pointer;"><</span>'; //创建年份下拉框[1900-2099]年onchange="changeYearAndMonth()"> createDoc += '<select id ="selectYear" class="selectStyle"';

目前可以实现需求了,但还有很多的不足,如果有好的建议,欢迎留言哦~
