WordPress 建站教程:给站点添加倒计时功能实现
在发布活动时,准备人活动截止日期很有必要,今天这个教程“WordPress 教程:给站点添加倒计时功能实现”就是实现这个功能的。
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。
