html计算器代码

当然可以。下面是一个简单的HTML计算器代码示例。这个计算器可以执行基本的加、减、乘、除运算。你可以将这段代码复制到HTML文件中，并在浏览器中打开它来使用计算器。

```html简单计算器 body { fontfamily: Arial, sansserif; } .calculator { width: 300px; margin: 50px auto; } .calculatorscreen { width: 100%; padding: 10px; marginbottom: 10px; border: 1px solid ccc; borderradius: 5px; textalign: right; } .calculatorkey { width: 25%; padding: 10px; margin: 5px; border: 1px solid ccc; borderradius: 5px; textalign: center; cursor: pointer; } .calculatorkey:active { backgroundcolor: eee; }

1 2 3 4 5 6 7 8 9 0 = C /

let currentOperand = '';let previousOperand = '';let operation = null;

function appendNumber { if { currentOperand = currentOperand.toString number.toString; updateDisplay; }}

function chooseOperation { if return; if { calculate; } previousOperand = currentOperand; currentOperand = ''; this.operation = operation;}

function setOperation { chooseOperation; updateDisplay;}

function clearResult { currentOperand = ''; previousOperand = ''; operation = null; updateDisplay;}

function calculate { let computation; const prev = parseFloat; const current = parseFloat; if || isNaNqwe2 return; switch { case ' ': computation = prev current; break; case '': computation = prev current; break; case '': computation = prev current; break; case '/': computation = prev / current; break; default: return; } currentOperand = computation; operation = null; previousOperand = ''; updateDisplay;}

function updateDisplay { document.getElementById.value = currentOperand;}

这个计算器包含基本的数字键和操作符键，可以执行加、减、乘、除运算。你可以根据需要修改样式和功能。
