我正在嘗試制作一個(gè)倒數(shù)計(jì)數(shù)器。如果我使用來自用戶機(jī)器的 JS 日期/時(shí)間，下面的代碼工作正常。我想更改它以從服務(wù)器獲取日期/時(shí)間。當(dāng)我在JS代碼中使用PHP日期時(shí)，除非我刷新頁面，否則倒計(jì)時(shí)計(jì)時(shí)器不會(huì)計(jì)數(shù)的問題。以下是當(dāng)前日期/時(shí)間的 php：$date = date('Y/m/d H:i:s');然后在這里我將 $date 添加到 JS 函數(shù)中：var DownDate = new Date("Feb 5, 2050 23:50:00").getTime();var ax = setInterval(function() {//var anow = new Date().getTime(); // JS date will work fine, but I don't want to rely on user's machine time. So next is the same but using php date/time.var anow = new Date("<?php echo $date; ?>").getTime();var adistance = DownDate - anow;var aminutes = Math.floor((adistance % (1000 * 60 * 60)) / (1000 * 60));  var aseconds = Math.floor((adistance % (1000 * 60)) / 1000);  document.getElementById("timer").innerHTML =    aminutes + "m " + aseconds + "s ";}, 1000);
