js文件内如何在php前端调用显示

function siteTime(){
window.setTimeout("siteTime()", 1000);
var seconds = 1000
var minutes = seconds * 60
var hours = minutes * 60
var days = hours * 24
var years = days * 365
var today = new Date()
var todayYear = today.getFullYear()
var todayMonth = today.getMonth()
var todayDate = today.getDate()
var todayHour = today.getHours()
var todayMinute = today.getMinutes()
var todaySecond = today.getSeconds()
var t1 = Date.UTC(2016,7,16,11,19,00)
var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond)
var diff = t2-t1
var diffYears = Math.floor(diff/years)
var diffDays = Math.floor((diff/days)-diffYears*365)
var diffHours = Math.floor((diff-(diffYears*365+diffDays)*days)/hours)
var diffMinutes = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours)/minutes)
var diffSeconds = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds)
document.getElementById("sitetime").innerHTML="本源已运行 "+diffYears+" 年 "+diffDays+" 天 "+diffHours+" 时 "+diffMinutes+" 分 "+diffSeconds+" 秒"
}
siteTime()

Answer 1

你的这段js代码调用，需要定义一个id为“ sitetime”的对象例如：
<div id="sitetime"></div> 标签可以是任何标签 注意css就可以了。
php代码中输出:<?php
echo '<div id="sitetime"></div>';
?>

php部分需要怎么写呢

追答

为什么要再php代码输出呢，你上面的代码根本不需要用到php啊，你就在标签上面给 id="sitetime" 就可以了 ，js代码通过外部文件引入。
说明：在span或者其他标签中加入 id="sitetime"';
?>
