Kod pernuh akan jadi seperti berikut:
<!DOCTYPE html>
<html manifest="cache.manifest">
<head>
<meta charset="utf-8"/>
<meta name="apple-mobile-web-app-capable" content="yes"/>
<title>Calculator</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.css"/>

<script>
var displayField;
$(document).ready(function() {
displayField = $('#display')
$("button").bind('tap', function() {
buttonPressed()
})
})
function buttonPressed() {
var buttonText = event.target.innerText
if (isCompute(buttonText)) {
compute()
} else if (isClear(buttonText)) {
clear()
} else if (isBackSpace(buttonText)) {
backSpace()
} else {
display(buttonText)
}
}
function isClear(buttonText) {
return "C" == buttonText
}
function isBackSpace(buttonText) {
return "\u21D0" == buttonText
}
function isCompute(buttonText) {
return "=" == buttonText
}
function display(buttonText) {
var newDisplay = displayField.val() + buttonText
displayField.val(newDisplay)
}
function clear() {
displayField.val("")
}
function backSpace() {
var display = displayField.val()
if (display.length > 0) {
var newDisplay = display.substr(0, display.length - 1)
displayField.val(newDisplay)
}
}
function compute() {
try {
var newDisplay = eval(displayField.val())
displayField.val(newDisplay)
} catch (error) {
displayField.val("Error")
}
