2，可以在手机上动态时钟代码吗1.可以实时动态显示当前时间与当前日期2.代码结构简洁、清晰、明了知识的汇总：1.HTML52.CSS33.JavaScript重难点汇总：1.各个指针的旋转角度的获?。?首先要明确以下概念：一周为360度、12小时、60分钟、60秒；公式：一周的度数/一周的时间；即得出时针每过一小时要旋转30度；分针每过一分钟要旋转6度；秒针每过一秒钟要旋转6度；下面是代码部分：HTML:<div id="box"><div id="h"></div><div id="min"></div><div id="s"><div class="cen"></div></div><div id="data"></div></div>CSS3:bodybackground-color: #aaa;margin: 0px; padding: 0px;}#boxwidth: 400px;height: 400px;border-radius: 100%;background: url(img/4706.jpg_wh860.jpg)0px 0px no-repeat;background-size: 400px;position: absolute;left: 500px;top: 200px;}#hwidth: 100px;height: 10px;background-color: red;position: relative;top: 195px;left: 200px;}#minwidth: 140px;height: 10px;background-color: yellow;position: relative;top: 185px;left: 200px;}#swidth: 180px;height: 10px;background-color: blue;position: relative;top: 175px;left: 200px;}.cenwidth: 10px;height: 10px;background-color: white;border-radius: 100%;}#dataposition: relative;top: 100px;left: 150px;color: red;font-size: 20px;}JavaScript:function tim()var d = new Date(),//获取当前系统时间year = d.getFullYear(),//得到当前年份mon = d.getMonth(),//得到当前月份date = d.getDate(), //得到当前日期hours = d.getHours(), //得到当前小时minutes = d.getMinutes(), //得到当前分钟seconds = d.getSeconds();//得到当前秒var hou = "";if(hours>12)hou = "下午";}elsehou = "上午";}document.getElementById("data").innerHTML= year+"年"+mon+"月"+date+"日"+"<br />"+hou;var n = document.getElementById("s");//获取秒针IDn.style.transform = "rotate("+(seconds*6-90)+"deg)";//通过当前秒数，得到秒针旋转度数n.style.transformOrigin = "left";//设置秒针旋转的基点var i = document.getElementById("min");//获取分针IDi.style.transform = "rotate("+(minutes*6-90)+"deg)"//通过当前分钟数，得到分针旋转度数i.style.transformOrigin = "left";//设置分针旋转的基点var h = document.getElementById("h");//获取时针IDh.style.transform = "rotate("+((hours*30)+(minutes*0.5)-90)+"deg)"//通过当前小时数 ， 得到时针旋转度数h.style.transformOrigin = "left";//设置时针旋转的基点}setInterval("tim()",1000);
3 ， 如何修改下列代码使时间可以动态显示用java是很难做到的 ， 时间动态显示要实时刷新页面，即使用一个线程单独控制也必须用js来完成<html xmlns=" http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>无标题文档</title> <script language="javascript"> var t = null; t = setTimeout(time,1000); function time() 用JS写【动态时间代码，如何用java写一个显示动态时间的程序in a HTML page with a colorful】
4，js如何实现动态倒计时效果 js实现动态倒计时效果的步骤：首先是获取到用户输入的目标时间，在获取当前时间，用目标时间减去当前时间，获得时间差；然后，将得到的时间差传化为天数、小时、分钟、秒钟；最后，动态的输出这些剩余时间 。下面我们就来一步一步的实现动态倒计时：1、建立显示的样式html代码：<form>目的日期：<br><br> <input type="text" id="year"><span>年</span> <input type="text" id="month"><span>月</span> <input type="text" id="day"><span>日</span><br><br> <input type="text" id="hour"><span>时</span> <input type="text" id="minute"><span>分</span> <input type="text" id="second"><span>秒</span><br><br> <input type="button" value="http://www.lisdn.com/mnsj/hhwd/确定" onclick="show()"></form><br><br><div class="time1">还剩时间：<br><br> <span id="_d"></span>天<span id="_h"></span>时 <span id="_m"></span>分 <span id="_s"></span>秒</div>css代码：input.time1 span2、实现动态倒计时--js代码第一步：首先是要获取到目标时间，当我们在页面输入目标日期，点击确认后 ， 得到目标时间 。function show() //获取目的日期 var myyear=document.getElementById("year").value; var mymonth=document.getElementById("month").value-1; var myday=document.getElementById("day").value; var myhour=document.getElementById("hour").value; var myminute=document.getElementById("minute").value; var mysecond=document.getElementById("second").value; var time=Number(new Date(myyear,mymonth,myday,myhour,myminute,mysecond));}第二步：获取当前时间、然后用目标时间减去当前时间 ， 得到剩余时间，即时间差 。//获取当前时间 var nowTime=Date.now();//获取时间差var timediff=Math.round((time-nowTime)/1000);第三步：将得到的时间差传化为天数、时、分、秒//获取还剩多少天var day=parseInt(timediff/3600/24);//获取还剩多少小时var hour=parseInt(timediff/3600%24);//获取还剩多少分钟var minute=parseInt(timediff/60%60);//获取还剩多少秒var second=timediff%60;第四步：输出剩余时间//输出还剩多少时间document.getElementById("_d").innerHTML=day;document.getElementById("_h").innerHTML=hour;document.getElementById("_m").innerHTML=minute;document.getElementById("_s").innerHTML=second;效果图：此时还不是动态的输出 ， 还需要我们手动的不断刷新，在输入目标日期 。第五步：使用定时器setTimeout()，动态输出时间setTimeout(show,1000);if(timediff==0) var set=setTimeout(show,1000);if(timediff==0)动态效果图：说明：setInterval() ：定义一个间隔性触发计时器，会按照指定的周期（以毫秒计）来调用函数或计算表达式 。该方法会不停地调用函数 ， 直到 调用clearInterval()方法来停止setInterval()计时器或窗口被关闭 。总结：5，Java中如何实现显示动态的时间利用死循环和线程，让线程在循环中每sleep1秒，重新获取下系统时间不就是动态显示时间了吗while(true)Date date=new Date(System.currentTimeMillis());SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-ddHH:mm:ss");System.out.println(date);//每一秒刷新下时间tryThread.sleep(1000);//sleep是以ms为单位} catch (InterruptedException e)// TODO Auto-generated catch blocke.printStackTrace();}}你可以试下代码，看看是不是你要的效果用timeout(function(){//这个是显示时间的方法 ， Date要重新new的},1000)间隔时间一秒6，谁能为我提供一个动态时间程序<script language="javascript">function showClock() var now = new Date(); var year= now.getFullYear(); var month= now.getMonth(); var date= now.getDate(); var day= now.getDay(); var hours= now.getHours(); var minutes = now.getMinutes(); var seconds = now.getSeconds(); var clck = (hours>=12)?"下午":"上午"; if(hours<=4) clck="夜深了，注意身体，该休息了，白天再忙吧！"; }else if(hours<12) clck="<font color=#ff3300>上午好，又是美好的一天！</font>"; }else if(hours<18) clck="<font color=#ff3300>下午好！外面天气好吗？记得朵朵白云捎来朋友殷殷的祝福 。</font>"; }else if(hours<22) clck="<font color=#ff3300>吃过晚饭了吧！上网放松一下一天的工作 。</font>"; }else clck="<font color=#ff3300>这么晚了，洗洗睡吧！但愿不会影响您明天的工作！</font>"; } hours = (hours<10)?"0"+hours:hours; minutes = (minutes<10)?"0"+minutes:minutes; seconds = (seconds<10)?"0"+seconds:seconds; switch(day) case 0: day="星期日";
