layui时间范围

//时间范围String time_range = para.getString("time_range", "");if (!StrUtil.isEmpty(time_range)) {String dateArr[] = time_range.split("-");if (dateArr.length == 2) {para.put("start_date", dateArr[0].trim().replace("/", ""));para.put("end_date", dateArr[1].trim().replace("/", ""));}}

前端

<input type="text" class="layui-input" id="time_range"placeholder=" - ">

        var date = new Date();var end_date = formatDate(date);var start_date = computeDate(date, -7);var date_str = start_date.replaceAll('-', '/') + " - " + end_date.replaceAll('-', '/');layui.laydate.render({elem: '#time_range',range: true,format: 'yyyy/MM/dd',value: date_str,done: function (value, date) {listStorage(value);}});

日期格式化

function formatDate (date) {if(null == date || undefined == date){date = new Date();}var year = date.getFullYear()var month = this.changeNum(date.getMonth() + 1)var day = this.changeNum(date.getDate())return `${year}-${month}-${day}`;
}function changeNum (num) {if (num >= 10) {return num} else {return '0' + num}
}

计算日期

/*** 计算距离某日期n天前/后的日期（年月日）*/
function computeDate(beginDate, addDay) {if(null == beginDate || undefined == beginDate){beginDate = new Date();}this.today = this.formatDate(beginDate)var beginTime = beginDate.getTime()var endTime = beginTime + addDay * 24 * 60 * 60 * 1000beginDate.setTime(endTime)return this.formatDate(beginDate);
