Di bawah ini script aba-aba kalkulator untuk menciptakan aplikasi dengan basic yang akan agan terapkan pada mata pelajaran kuliah, kiprah kuliah, maupun pola skripsi bagi anak it.
<html> <head> <style type="text/css"> * { margin: 0; padding: 0; box-sizing: border-box; font: bold 14px Arial, sans-serif; } html { height: 100%; background: white; background: radial-gradient(circle, #E6E6FA 20%, #ccc); background-size: cover; } #calculator { width: 325px; height: auto; margin: 10px auto; padding: 20px 20px 9px; background: #008000; background: linear-gradient(#008000, #ADFF2F); border-radius: 3px; box-shadow: 0px 4px #808080, 0px 10px 15px rgba(0, 0, 0, 0.2); } .top span.clear { float: left; } .top .screen { height: 40px; width: 212px; float: right; padding: 0 10px; background: rgba(0, 0, 0, 0.2); border-radius: 3px; box-shadow: inset 0px 4px rgba(0, 0, 0, 0.2); font-size: 17px; line-height: 40px; color: white; text-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); text-align: right; letter-spacing: 1px; } .keys, .top {overflow: hidden;} .keys span, .top span.clear { float: left; position: relative; top: 0; cursor: pointer; width: 66px; height: 36px; background: Lightseagreen; border-radius: 3px; box-shadow: 0px 4px rgba(0, 0, 0, 0.2); margin: 0 7px 11px 0; color: #888; line-height: 36px; text-align: center; user-select: none; transition: all 0.2s ease; } .keys span.operator { background: #87CEEB; margin-right: 0; } .keys span.eval { background: #00FF7F; box-shadow: 0px 4px #9da853; color: #888e5f; } .top span.clear { background: #40E0D0; box-shadow: 0px 4px #708090; color: white; } /* Some hover effects */ .keys span:hover { background: #9c89f6; box-shadow: 0px 4px #6b54d3; color: white; } .keys span.eval:hover { background: #abb850; box-shadow: 0px 4px #717a33; color: #ffffff; } .top span.clear:hover { background: #f68991; box-shadow: 0px 4px #d3545d; color: white; } .keys span:active { box-shadow: 0px 0px #6b54d3; top: 4px; } .keys span.eval:active { box-shadow: 0px 0px #717a33; top: 4px; } .top span.clear:active { top: 4px; box-shadow: 0px 0px #d3545d; } </style> </head> <body> <div id="calculator"> <!-- Screen and clear key --> <div class="top"> <span class="clear">C</span> <div class="screen"></div> </div> <div class="keys"> <!-- operators and other keys --> <span>7</span> <span>8</span> <span>9</span> <span class="operator">+</span> <span>4</span> <span>5</span> <span>6</span> <span class="operator">-</span> <span>1</span> <span>2</span> <span>3</span> <span class="operator">÷</span> <span>0</span> <span>.</span> <span class="eval">=</span> <span class="operator">x</span> </div> </div> <!-- PrefixFree --> <script type="text/javascript"> var keys = document.querySelectorAll('#calculator span'); var operators = ['+', '-', 'x', '÷']; var decimalAdded = false; for(var i = 0; i < keys.length; i++) { keys[i].onclick = function(e) { var input = document.querySelector('.screen'); var inputVal = input.innerHTML; var btnVal = this.innerHTML; if(btnVal == 'C') { input.innerHTML = ''; decimalAdded = false; } else if(btnVal == '=') { var equation = inputVal; var lastChar = equation[equation.length - 1]; equation = equation.replace(/x/g, '*').replace(/÷/g, '/'); if(operators.indexOf(lastChar) > -1 || lastChar == '.') equation = equation.replace(/.$/, ''); if(equation) input.innerHTML = eval(equation); decimalAdded = false; } else if(operators.indexOf(btnVal) > -1) { var lastChar = inputVal[inputVal.length - 1]; if(inputVal != '' && operators.indexOf(lastChar) == -1) input.innerHTML += btnVal; else if(inputVal == '' && btnVal == '-') input.innerHTML += btnVal; if(operators.indexOf(lastChar) > -1 && inputVal.length > 1) { input.innerHTML = inputVal.replace(/.$/, btnVal); } decimalAdded =false; } else if(btnVal == '.') { if(!decimalAdded) { input.innerHTML += btnVal; decimalAdded = true; } } else { input.innerHTML += btnVal; } e.preventDefault(); } } </script> </body> </html> Namun bila tidak suka dengan warna atau kotak kotak tampilan kalkulator menyerupai demo di atas, agan dapat edit edit dengan html pada post blog dengan perlahan, baik dari gradasi warna, bentuk dan lain sebagainya.
Cukup sekian artikel yang aku bagikan script aba-aba kalkulator ini, supaya membantu.
