133、纯JavaScript时钟

133、纯JavaScript时钟

脚本说明:

第一步:把如下代码加入<head>区域中:

<SCRIPT language=javascript>

<!--

pX=400;pY=200

obs = new Array(13)

function ob () {

for (i=0; i<13; i++) {

       if (document.all) obs[i]=new Array (eval('ob'+i).style,-100,-100)

       else obs[i] = new Array (eval('document.ob'+i),-100,-100)

       }

}

function cl(a,b,c){

       if (document.all) {

              if (a!=0) b+=-1

              eval('c'+a+'.style.pixelTop='+(pY+(c)))

              eval('c'+a+'.style.pixelLeft='+(pX+(b)))

              }

else{

       if (a!=0) b+=10

       eval('document.c'+a+'.top='+(pY+(c)))

       eval('document.c'+a+'.left='+(pX+(b)))

}

if (document.all) c0.style.pixelLeft=26

}

 

function runClock() {

       for (i=0; i<13; i++) {

              obs[i][0].left=obs[i][1]+pX

              obs[i][0].top=obs[i][2]+pY

       }

}

 

var lastsec

function timer() {

       time = new Date ()

       sec = time.getSeconds()

       if (sec!=lastsec) {

 

              lastsec = sec

              sec=Math.PI*sec/30

              min=Math.PI*time.getMinutes()/30

              hr =Math.PI*((time.getHours()*60)+time.getMinutes())/360

              for (i=1;i<6;i++) {

                     obs[i][1] = Math.sin(sec) * (44 - (i-1)*11)-16;

                     if (document.layers)obs[i][1]+=10;

                     obs[i][2] = -Math.cos(sec) * (44 - (i-1)*11)-27;

              }

              for (i=6;i<10;i++) {

                     obs[i][1] = Math.sin(min) * (40 - (i-6)*10)-16;

                     if (document.layers)obs[i][1]+=10;

                     obs[i][2] = -Math.cos(min) * (40 - (i-6)*10)-27;

              }

              for (i=10;i<13;i++) {

                     obs[i][1] = Math.sin(hr) * (37 - (i-10)*11)-16;

                     if (document.layers)obs[i][1]+=10;

                     obs[i][2] = -Math.cos(hr) * (37 - (i-10)*11)-27;

              }

       }

 

}

function setNum(){

 

cl (0,-67,-65);

cl (1,10,-51);

cl (2,28,-33);

cl (3,35,-8);

cl (4,28,17);

cl (5,10,35);

cl (6,-15,42);

cl (7,-40,35);

cl (8,-58,17);

cl (9,-65,-8);

cl (10,-58,-33);

cl (11,-40,-51);

cl (12,-16,-56);

 

}

</SCRIPT>

 

 

第二步:<body>中加入如下代码:

<div id="c0" style="position:absolute;right:6;top:6; z-index:2;">

 

        <div id="c1" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>1</b></div>

        <div id="c2" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>2</b></div>

        <div id="c3" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>3</b></div>

        <div id="c4" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>4</b></div>

        <div id="c5" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>5</b></div>

        <div id="c6" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>6</b></div>

        <div id="c7" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>7</b></div>

        <div id="c8" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>8</b></div>

        <div id="c9" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>9</b></div>

        <div id="c10" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>10</b></div>

        <div id="c11" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>11</b></div>

        <div id="c12" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>12</b></div>

        <div id="ob0" style="position:absolute;left:-20;top:-20;z-index:1">  </div>

        <div id="ob1" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

        <div id="ob2" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

        <div id="ob3" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

        <div id="ob4" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

        <div id="ob5" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

        <div id="ob6" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>

        <div id="ob7" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>

        <div id="ob8" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>

        <div id="ob9" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>

        <div id="ob10" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>

        <div id="ob11" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>

        <div id="ob12" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>

 

 

第三步:把<body>中内容改为:

<body bgcolor="#fef4d9" onLoad="ob(),setNum(),setInterval('timer()',100);setInterval('runClock()',100)">
