php date into javascript

Question

我有php日期：

<?php
date_default_timezone_set('Europe/London');
 echo date('D M d Y H:i:s O');
?>

和JavaScript/jquery脚本在网站上发布日期：

setInterval(function() {
var d = new Date("<?  echo date('D M d Y H:i:s O'); ?>")
currentHours = d.getHours();
currentHours = ("0" + currentHours).slice(-2);
currentMinutes = d.getMinutes();
currentMinutes = ("0" + currentMinutes).slice(-2);
currentSec = d.getSeconds();
currentSec = ("0" + currentSec).slice(-2);

    $('#timer').text((currentHours +':' +  currentMinutes + ':' + currentSec ));
},

但是javascript返回aN：aN

：aN如何将服务器时间插入javascript？

Answer 1

您可以简单地将new Date()用作

<script>
    function myFunction(obj) {
        var today = new Date("<?php echo date('Y-m-d H:i:s')?>");
        var hh = today.getHours();
        var ii = today.getMinutes();
        var ss = today.getSeconds();
        if (hh < 10) {
            hh = '0' + hh
        }
        if (ii < 10) {
            ii = '0' + ii
        }
        if (ss < 10) {
            ss = '0' + ss
        }

        obj.value = hh + ':' + ii + ':' + ss;
    }
</script>
<input type="text" onclick="myFunction(this);">

Answer 2

按如下方式使用代码：

我刚刚new Date("<? echo date('D M d Y H:i:s O'); ?>")替换到

new Date("<?php echo date('D M d Y H:i:s O'); ?>")

它为我工作

var d = new Date("<?php echo date('D M d Y H:i:s O'); ?>")
        alert(d);
currentHours = d.getHours();
currentHours = ("0" + currentHours).slice(-2);
currentMinutes = d.getMinutes();
currentMinutes = ("0" + currentMinutes).slice(-2);
currentSec = d.getSeconds();
currentSec = ("0" + currentSec).slice(-2);

    $('#timer').text((currentHours +':' +  currentMinutes + ':' + currentSec ));

Answer 3

你在 php 日期中打错了字，它应该是字符串末尾的 0（零）而不是 O。

setInterval(function() {
var d = new Date("<?  echo date('D M d Y H:i:s 0'); ?>")
currentHours = d.getHours();
currentHours = ("0" + currentHours).slice(-2);
currentMinutes = d.getMinutes();
currentMinutes = ("0" + currentMinutes).slice(-2);
currentSec = d.getSeconds();
currentSec = ("0" + currentSec).slice(-2);

    $('#timer').text((currentHours +':' +  currentMinutes + ':' + currentSec ));
},
