OneNav主题-为主题添加人生倒计时

教程开始：

第一步-先要放在什么位置，我的放在独立页面，加入以下代码：

<!-- 时间倒计时代码 -->
<div class="sidebar-box classListBox">
<div class="aside aside-count">
<div class="p-3"><span style="font-size: 1.2em; color: orange;"><i class="fas fa-hourglass-half"></i></span> 人生倒计时</div>
<div class="content">
<div class="item" id="dayProgress">
<div class="title">今日已经过去<span></span>小时</div>
<div class="progress">
<div class="progress-bar">
<div class="progress-inner progress-inner-1"></div>
</div>
<div class="progress-percentage"></div>
</div>
</div>
<div class="item" id="weekProgress">
<div class="title">这周已经过去<span></span>天</div>
<div class="progress">
<div class="progress-bar">
<div class="progress-inner progress-inner-2"></div>
</div>
<div class="progress-percentage"></div>
</div>
</div>
<div class="item" id="monthProgress">
<div class="title">本月已经过去<span></span>天</div>
<div class="progress">
<div class="progress-bar">
<div class="progress-inner progress-inner-3"></div>
</div>
<div class="progress-percentage"></div>
</div>
</div>
<div class="item" id="yearProgress">
<div class="title">今年已经过去<span></span>个月</div>
<div class="progress">
<div class="progress-bar">
<div class="progress-inner progress-inner-4"></div>
</div>
<div class="progress-percentage"></div>
</div>
</div>
</div>
</div>
</div>
<!-- 时间倒计时代码 -->

第二步-添加完成后,在主题后台自定义css里添加如下代码，一般都是在主题设置-自定义设置-自定义CSS样式丢进去就行了

/* 人生倒计时css */
.aside-count .content {
padding: 15px
}

.aside-count .content .item {
margin-bottom: 15px
}

.aside-count .content .item:last-child {
margin-bottom: 0
}

.aside-count .content .item .title {
font-size: 12px;
color: var(--minor);
margin-bottom: 5px;
display: flex;
align-items: center
}

.aside-count .content .item .title span {
color: var(--theme);
font-weight: 500;
font-size: 14px;
margin: 0 5px
}

.aside-count .content .item .progress {
display: flex;
align-items: center
}

.aside-count .content .item .progress .progress-bar {
height: 10px;
border-radius: 5px;
overflow: hidden;
background: var(--classC);
width: 0;
min-width: 0;
flex: 1;
margin-right: 5px
}
@keyframes progress {
0% {
background-position: 0 0
}

100% {
background-position: 30px 0
}
}
.aside-count .content .item .progress .progress-bar .progress-inner {
width: 0;
height: 100%;
border-radius: 5px;
transition: width 0.35s;
-webkit-animation: progress 750ms linear infinite;
animation: progress 750ms linear infinite
}

.aside-count .content .item .progress .progress-bar .progress-inner-1 {
background: #bde6ff;
background-image: linear-gradient(135deg, #50bfff 25%, transparent 25%, transparent 50%, #50bfff 50%, #50bfff 75%, transparent 75%, transparent 100%);
background-size: 30px 30px
}

.aside-count .content .item .progress .progress-bar .progress-inner-2 {
background: #ffd980;
background-image: linear-gradient(135deg, #f7ba2a 25%, transparent 25%, transparent 50%, #f7ba2a 50%, #f7ba2a 75%, transparent 75%, transparent 100%);
background-size: 30px 30px
}

.aside-count .content .item .progress .progress-bar .progress-inner-3 {
background: #ffa9a9;
background-image: linear-gradient(135deg, #ff4949 25%, transparent 25%, transparent 50%, #ff4949 50%, #ff4949 75%, transparent 75%, transparent 100%);
background-size: 30px 30px
}

.aside-count .content .item .progress .progress-bar .progress-inner-4 {
background: #67c23a;
background-image: linear-gradient(135deg, #4f9e28 25%, transparent 25%, transparent 50%, #4f9e28 50%, #4f9e28 75%, transparent 75%, transparent 100%);
background-size: 30px 30px
}

.aside-count .content .item .progress .progress-percentage {
color: var(--info)
}
/*人生倒计时css*/

第三步-添加完成后,在到主题文件/js/里面创建名为timeinfo.js后把下面代码复制进去保存.

function init_life_time() {
function getAsideLifeTime() {
/* 当前时间戳 */
let nowDate = +new Date();
/* 今天开始时间戳 */
let todayStartDate = new Date(new Date().toLocaleDateString()).getTime();
/* 今天已经过去的时间 */
let todayPassHours = (nowDate - todayStartDate) / 1000 / 60 / 60;
/* 今天已经过去的时间比 */
let todayPassHoursPercent = (todayPassHours / 24) * 100;
$('#dayProgress .title span').html(parseInt(todayPassHours));
$('#dayProgress .progress .progress-inner').css('width', parseInt(todayPassHoursPercent) + '%');
$('#dayProgress .progress .progress-percentage').html(parseInt(todayPassHoursPercent) + '%');
/* 当前周几 */
let weeks = {
0: 7,
1: 1,
2: 2,
3: 3,
4: 4,
5: 5,
6: 6
};
let weekDay = weeks[new Date().getDay()];
let weekDayPassPercent = (weekDay / 7) * 100;
$('#weekProgress .title span').html(weekDay);
$('#weekProgress .progress .progress-inner').css('width', parseInt(weekDayPassPercent) + '%');
$('#weekProgress .progress .progress-percentage').html(parseInt(weekDayPassPercent) + '%');
let year = new Date().getFullYear();
let date = new Date().getDate();
let month = new Date().getMonth() + 1;
let monthAll = new Date(year, month, 0).getDate();
let monthPassPercent = (date / monthAll) * 100;
$('#monthProgress .title span').html(date);
$('#monthProgress .progress .progress-inner').css('width', parseInt(monthPassPercent) + '%');
$('#monthProgress .progress .progress-percentage').html(parseInt(monthPassPercent) + '%');
let yearPass = (month / 12) * 100;
$('#yearProgress .title span').html(month);
$('#yearProgress .progress .progress-inner').css('width', parseInt(yearPass) + '%');
$('#yearProgress .progress .progress-percentage').html(parseInt(yearPass) + '%');
}
getAsideLifeTime();
setInterval(() => {
getAsideLifeTime();
}, 1000);
}
init_life_time()

第四步-最后到页脚里面引入此js.(放在上面即可）

<!-- 倒计时引用的JS -->
<script src="<?php $this->options->themeUrl('assets/js/timeinfo.js'); ?>"></script>
<!-- 倒计时引用的JS -->

以上就是完整的代码，复制过去记得不要放错的位置，注意排查细节如果出现了进度条无法显示等问题，根本原因在于你没有引入第三方库需要加载jquery，
