我有一些未完成的代碼，它應(yīng)該為我點擊的任何按鈕返回一個數(shù)字，但它什么也不做，控制臺也不會拋出錯誤，所以我看不到我做了什么。我做了一些拼寫檢查，我的代碼主要來自一個 youtube 視頻。const minus = document.querySelector('[data-delete]');const current = document.querySelector('[data-input]');const allClear = document.querySelector('[data-all-clear]');const numberButtons = document.querySelectorAll('[data-number]')const operation = document.querySelectorAll('[data-operation]') const equals =document.querySelector('[data-equals]')class Calc { constructor(inputText){ this.inputText = current this.clear() } clear(){ this.input='' this.operation=undefined } delete(){ } writeNumber(num){ this.input = num } operation(sign){ } compute(){ } updateDisplay(){ this.input.innerText = this.operation }}const calculator = new Calc(current);numberButtons.forEach(number=>{equals.onClick('click',()=>{ calculator.appendNumber(equals.innerText) calculator.updateDisplay()})}) <!DOCTYPE html><html> <head> <meta charset="UTF-8"> <title>Calculator</title> <link href="calc.css" rel="stylesheet"> <script src="calc.js"></script> </head> <body> <div class="container-grid"> <div data-input class="input">3</div> <button data-all-clear class="span-two">AC</button> <button data-delete>DEL</button> <button data-operation>/</button> <button data-number>1</button> <button data-number>2</button> <button data-number>3</button> <button data-operation>*</button> <button data-number>4</button> <button data-number>5</button> <button data-number>6</button> <button data-operation>+</button> <button data-number>7</button> <button data-number>8</button> <button data-number>9</button> <button data-operation>-</button> <button data-number>.</button> <button data-number>0</button> <button data-equals class = "span-two">=</button> </div> <script src="calc.js"></script> </body></html>我只想要按鈕顯示數(shù)字
為什么我的計算器代碼不起作用？
