如何添加"from“和" to”搜索栏

<input type="text" id="fromInput" placeholder="From">
<input type="text" id="toInput" placeholder="To">
<button id="searchButton">Search</button>

const fromInput = document.getElementById("fromInput");
const toInput = document.getElementById("toInput");
const searchButton = document.getElementById("searchButton");

searchButton.addEventListener("click", function() {
  const fromValue = fromInput.value;
  const toValue = toInput.value;
  
  // 在这里编写处理搜索逻辑的代码
});
