从外部获取函数参数，而不在javascript中执行此函数

function getData() {
  const urlParams = new URLSearchParams(window.location.search);
  const id = urlParams.get('id');
  const name = urlParams.get('name');
  // 执行函数逻辑
}

<form id="myForm">
  <input type="text" name="id" />
  <input type="text" name="name" />
  <button type="submit">提交</button>
</form>

document.getElementById('myForm').addEventListener('submit', function(event) {
  event.preventDefault(); // 阻止表单默认提交行为
  const id = this.elements.id.value;
  const name = this.elements.name.value;
  // 执行函数逻辑
});

fetch('https://example.com/api/data?id=123&name=John')
  .then(response => response.json())
  .then(data => {
    const id = data.id;
    const name = data.name;
    // 执行函数逻辑
  });
