wordpress不用插件实现倒计时的功能
前面介绍了wordpress自定义样式倒计时插件jcountdown ,插件的话不受主题更换的影响,如何需要用代码实现的话,下面给大家分享不用插件如何实现倒计时功能。
第一步新增一个js文件
countdown.js,代码如下:
function ShowCountDown(prefix,year,month,day,hourd,minuted,seconded){ var now = new Date(); if( typeof(hourd) == "undefined" ) hourd=23; if( typeof(minuted) == "undefined" ) minuted=59; if( typeof(seconded) == "undefined" ) seconded=59; var endDate = new Date(year, month-1, day, hourd, minuted,seconded); 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 day2 = (day<10?"0"+day:day); var hour2 = (hour<10?"0"+hour:hour); var minute2 = (minute<10?"0"+minute:minute); var second2 = (second<10?"0"+second:second); jQuery("#"+prefix+"_countDown_day").html(day); jQuery("#"+prefix+"_countDown_hour").html(hour2); jQuery("#"+prefix+"_countDown_min").html(minute2); jQuery("#"+prefix+"_countDown_sec").html(second2); }
第二步在functions.php中加入下面代码,引用刚刚的js文件:
function Brain_countdown($atts, $content=null) { extract(shortcode_atts(array("time" => ''), $atts)); extract(shortcode_atts(array("prefix" => ''), $atts)); date_default_timezone_set('PRC'); $endtime=strtotime($time); $nowtime=time(); $counttime=$endtime-$nowtime; $day=floor($counttime/(60*60*24)); $day=$day<10 ? "0".$day : $day; $hour=floor(($counttime-$day*24*60*60)/3600); $hour=$hour<10 ? "0".$hour : $hour; $min=floor(($counttime-$day*24*60*60-$hour*3600)/60); $min=$min<10 ? "0".$min : $min; $sect=floor($counttime-$day*24*60*60-$hour*3600-$min*60-1); $sect=$sect<10 ? "0".$sect : $sect; $endtimes = str_replace(array("-"," ",":"),",",$time); if($endtime>$nowtime){ return ' <div class="countDownCont">活动倒计时: <span id="'.$prefix.'_countDown_day" style="left: 10px;">'.$day.'</span>天 <span id="'.$prefix.'_countDown_hour" style="left: 125px;">'.$hour.'</span>时 <span id="'.$prefix.'_countDown_min" style="left: 232px;">'.$min.'</span>分 <span id="'.$prefix.'_countDown_sec" style="left: 342px;">'.$sect.'</span>秒</div> <script>window.setInterval(function(){ShowCountDown("'.$prefix.'" , '.$endtimes.' );}, 1000);</script> '; }else{ return $content; } } add_shortcode('countdown', 'Brain_countdown'); wp_register_script( 'Brain_countdown_head_JS', get_template_directory_uri() . '/js/countdown.js', array(), '1.0', false ); wp_enqueue_script( 'Brain_countdown_head_JS' );
调用方法:(去掉countdown 中间的“——”号。)
[count——down time='2018-7-10 20:30:30' prefix='pro1']活动已结束[/count——down]
显示效果如下:
