如何制作一个网页Calculator
时间显示js
<script>
function show(){
var date = new Date(); //日期对象
var now = "";
now = date.getFullYear()+"年"; //读英文就行了
now = now + (date.getMonth()+1)+"月"; //取月的时候取的是当前月-1如果想取当前月+1就可以了
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>
调用数字js
<script>
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>
布局部分
<body>
<h2 align=right> <font color="#cc0033">
<body onload="show()"> <!-- 网页加载时调用一次 以后就自动调用了-->
<div id="nowDiv"></div>
</font></h2>
</body>
<style type="text/css">body {background:url(4.jpg)}</style>>
<font color="red" size="6"><center>大胖小秀</center></font>
<p></p>
<!--定义按键表格,每个按键对应一个事件触发-->
