纯代码为WordPress站点添加倒计时功能
久伴觉得这个教程很实用,特别是发布某些活动,是活动肯定有截止日期,所以博客在发布活动类型的文章底部添加一个活动结束倒计时还是不错的-本文来源:boke112导航
纯代码添加倒计时到 WordPress
1、把下面的代码保存为 countdownjs.js,保存在当前所使用主题的 js/目录里:
- function getAdd(time){
- if(time<10){
- return “0”+time;
- }else{
- return time;
- }
- }
- var interval = 1000;
- function ShowCountDown(year,month,day,hourd,minuted){
- var now = new Date();
- var endDate = new Date(year, month-1, day, hourd, minuted);
- var leftTime = endDate.getTime() – now.getTime();
- var leftsecond = parseInt(leftTime/1000);
- var day = Math.floor(leftsecond/(60*60*24));
- day = day < 0 ? 0 : day;
- var hour = Math.floor((leftsecond-day*24*60*60)/3600);
- hour = hour < 0 ? 0 : hour;
- var minute = Math.floor((leftsecond-day*24*60*60-hour*3600)/60);
- minute = minute < 0 ? 0 : minute;
- var second = Math.floor(leftsecond-day*24*60*60-hour*3600-minute*60);
- second = second < 0 ? 0 : second;
- var getDay = getAdd(day);
- var getHour = getAdd(hour);
- var getMinute = getAdd(minute);
- var getSecond = getAdd(second);
- if(endDate > now){
- document.getElementById(‘time’).innerHTML = ‘活动倒计时:’;
- document.getElementById(‘day’).innerHTML = getDay +’天’;
- document.getElementById(‘hour’).innerHTML = getHour +’时’;
- document.getElementById(‘min’).innerHTML = getMinute +’分’;
- document.getElementById(‘sec’).innerHTML = getSecond +’秒’;
- }else{
- document.getElementById(‘countdown’).innerHTML= ‘本次活动已经结束’
- }
- }
2、把下面的代码添加到当前主题的 functions.php 文件最后一个 ?> 的前面:
- function countdown($atts, $content=null) {
- extract(shortcode_atts(array(“time” => ”), $atts));
- date_default_timezone_set(‘PRC’);
- $endtime=strtotime($time);
- $nowtime=time();
- global $endtimes;
- $endtimes = str_replace(array(“-“,” “,”:”),”,”,$time);
- if($endtime>$nowtime){
- return ‘
- <div id=”countdown”>
- <span id=”time”></span>
- <span id=”day”></span>
- <span id=”hour”></span>
- <span id=”min”></span>
- <span id=”sec”></span>
- </div>
- ‘;
- }else{
- return ‘本次活动已经结束’;
- }
- }
- function countdown_js() {
- global $endtimes;
- echo ‘<script>window.setInterval(function(){ShowCountDown(‘.$endtimes.’);}, interval);</script>’.”\n”;
- }
- add_shortcode(‘countdown’, ‘countdown’);
- add_action(‘wp_footer’, ‘countdown_js’);
- wp_register_script( ‘countdown_js’, get_template_directory_uri() . ‘/js/countdownjs.js’, array(), ‘1.0’, false);
- wp_enqueue_script( ‘countdown_js’ );
3、在发布/更新文章的时候,切换到文末模式,然后在想要插入倒计时的位置添加以下短代码:
- [countdown time=”2019-01-15 18:41:57″]
其中 time=”2019-01-15 18:41:57″引号中的时间就是活动结束时间,修改为其他日期时间时请保持格式一致即可。
