本文实例为大家分享了小程序实现横向滑动日历效果的具体代码,供大家参考,具体内容如下
{{ item.week }}
{{ item.date }}
js:
function getThisMonthDays(year, month) {
return new Date(year, month, 0).getDate();
}
// 计算每月第一天是星期几
function getFirstDayOfWeek(year, month) {
return new Date(Date.UTC(year, month - 1, 1)).getDay();
}
const date = new Date();
const cur_year = date.getFullYear();
const cur_month = date.getMonth() + 1;
const cur_date = date.getDate();
const weeks_ch = ['日', '一', '二', '三', '四', '五', '六'];
//利用构造函数创建对象
function calendar(date, week) {
this.date = cur_year + '-' + cur_month + '-' + date;
if (date == cur_date) {
this.week = "今天";
} else if (date == cur_date + 1) {
this.week = "明天";
} else {
this.week = '星期' + week;
}
}
//当前月份的天数
var monthLength = getThisMonthDays(cur_year, cur_month)
//当前月份的第一天是星期几
var week = getFirstDayOfWeek(cur_year, cur_month)
var x = week;
for (var i = 1; i <= monthLength; i++) {
//当循环完一周后,初始化再次循环
if (x > 6) {
x = 0;
}
//利用构造函数创建对象
that.data.calendar[i] = new calendar(i, [weeks_ch[x]][0])
x++;
}
//限制要渲染的日历数据天数为7天以内(用户体验)
var flag = that.data.calendar.splice(cur_date, that.data.calendar.length - cur_date <= 7 ? that.data.calendar.length : 7)
that.setData({
calendar: flag
})
selectd = flag;
// console.log(selectd);
var ret_id = [];
const lengths = selectd.length
for (let i = 0; i < lengths; i++) {
ret_id[i] = selectd[i].date;
}
choosedate = ret_id[0];
//设置scroll-view的子容器的宽度
that.setData({
width: 186 * parseInt(that.data.calendar.length - cur_date <= 7 ? that.data.calendar.length : 7)
})
CSS:
/*日历开始 */
scroll-view{
height: 128rpx;
width: 101%;
position:fixed;
top:355rpx;
}
scroll-view .list{
display: flex;
flex-wrap: nowrap;
justify-content: flex-start;
}
scroll-view .listItem{
text-align: center;
width:187rpx;
height: 128rpx;
background: #f4f4f4;
padding-top: 30rpx;
box-sizing: border-box;
display: inline-block;
}
scroll-view .listItem text{
display: block;
}
scroll-view .listItem .name{
font-size: 25rpx;
}
scroll-view .listItem .date{
font-size: 25rpx;
}
scroll-view .current{
background-color:pink;
width:200rpx;
position:relative;
}
scroll-view .current text{
color: #fff;
}
