js加减乘除按钮代码怎么实现

<code class="html"><button id="plus">+</button>
<button id="minus">-</button>
<button id="multiply">*</button>
<button id="divide">/</button>
<input type="number" id="number1">
<input type="number" id="number2">
<input type="text" id="result"></code>

<code class="js">const plusBtn = document.getElementById('plus');
const minusBtn = document.getElementById('minus');
const multiplyBtn = document.getElementById('multiply');
const divideBtn = document.getElementById('divide');

const number1 = document.getElementById('number1');
const number2 = document.getElementById('number2');
const result = document.getElementById('result');</code>

<code class="js">plusBtn.addEventListener('click', addNumbers);
minusBtn.addEventListener('click', subtractNumbers);
multiplyBtn.addEventListener('click', multiplyNumbers);
divideBtn.addEventListener('click', divideNumbers);</code>

<code class="js">function addNumbers() {
  result.value = parseFloat(number1.value) + parseFloat(number2.value);
}

function subtractNumbers() {
  result.value = parseFloat(number1.value) - parseFloat(number2.value);
}

function multiplyNumbers() {
  result.value = parseFloat(number1.value) * parseFloat(number2.value);
}

function divideNumbers() {
  result.value = parseFloat(number1.value) / parseFloat(number2.value);
}</code>

<code class="js">document.querySelector('form').addEventListener('submit', (e) => {
  e.preventDefault();
});</code>
