HTML网页之计算器代码
计算器网页效果显示：点击这里！
<script>
function show(){
var date = new Date(); //日期对象
var now = “”;
now = date.getFullYear()+”年”; //读英文即可了
now = now + (date.getMonth()+1)+”月”; //取月的时候取的是当前月-1假设想取当前月+1就能够了
now = now + date.getDate()+”日”;
now = now + date.getHours()+”时”;
now = now + date.getMinutes()+”分”;
now = now + date.getSeconds()+”秒”;
document.getElementById(“nowDiv”).innerHTML = now; //div的html是now这个字符串
setTimeout(“show()”,1000); //设置过1000毫秒就是1秒，调用show方法
}
</script>

<!–将按键内容以字符串形式存储在文字框中当button为“=”时。调用eval方法计算结果然后将结果输出文字框中–>
<script type=”text/javascript”>
var numresult;
var str;
function onclicknum(nums) {
str = document.getElementById(“nummessege”);
str.value = str.value + nums;
}
function onclickclear() {
str = document.getElementById(“nummessege”);
str.value = “”;
}
function onclickresult() {
str = document.getElementById(“nummessege”);
numresult = eval(str.value);
str.value = numresult;
}
</script>
<style type=”text/css”>
img{
position:absolute;
left:1100px;
top:100px;
}
</style>
</head>
<body> <!用来显示时间>
<h2 align=right><font color=”#cc0033″>
<body onload=”show()”> <!– 网页载入时调用一次 以后就自己主动调用了–>
<div id=”nowDiv”></div>
</font></h2>
</body>
<body bgcolor=”#9900ff” >

<!–定义按键表格,每一个按键相应一个事件触发–>
