Hallo sahabat kali ini saya akan poting bagaimana cara membuat program kalkulator sendiri.
Semoga potingan ini bermanfaat untuk sahabat semuanya.
Silahkan di simak.
Kalkulator simple ( a + b = c) dengan input angka melalui keyboard.So, begini deh script kalkulatornya :
<head>
<title>CALCULATOR</title>
<meta name="Programmer" content="Bayu Anugrah" />
<script language="javascript" type="<a title="text" href="http://www.kantorku-net.com/calculator">text</a>/javascript">
<!--
var flag = false;
function isi(num) {
if (flag) calc.b.value += num;
else calc.a.value += num;
}
function tambah()
{
calc.opr.value = ' + '
flag = true;
calc.b.focus()
}
function kurang()
{
calc.opr.value = ' - '
flag = true;
calc.b.focus()
}
function kosong()
{
calc.a.focus()
calc.a.value=""
calc.opr.value=""
calc.b.value=""
calc.c.value=""
flag = false;
}
//-->
</script>
<style type="text/css">
p {
font-family:verdana;
font-size:10px;
line-height:1.6em;
font-weight:bold;
color:#727272
}
.style2 {color: #000000}
.style3 {color: #FF0000}
.style4 {color: #FF0000; font-family: Verdana, Arial, Helvetica, sans-serif; }
</style>
</head>
<body onload=kosong()>
<center>
<p class="style4" style="padding:20px 0px 30px 0px"><font size="6">Calculator</font></p>
<form name="calc">
<table width="291" border="4" bordercolor="#3333ff">
<tr>
<td width="308">
<input type="text" name="a" size="2" />
<input type="text" name="opr" size="1" />
<input type="text" name="b" size="2" /> =
<input type="text" name="c" size="2" />
<input type="button" name="DoIt2" value=" = " onClick="calc.c.value=eval(calc.a.value+calc.opr.value+calc.b.value)" />
</td>
</tr>
</table>
</form>
<p class="style2">Code perintah kalkulator</p>
<p class="style2">+ = +<br>
- = -<br>
