问:使用javascript计算两个输入

function calculateSum() {
  var num1 = parseInt(document.getElementById("input1").value);
  var num2 = parseInt(document.getElementById("input2").value);
  var sum = num1 + num2;
  document.getElementById("result").innerHTML = "Sum: " + sum;
}

<input type="text" id="input1" placeholder="输入第一个数字">
<input type="text" id="input2" placeholder="输入第二个数字">
<button onclick="calculateSum()">计算和</button>
<p id="result"></p>
