我正在创建一个网页搜索引擎这里是我的代码：

<!-- Searching script -->
<script>
  function show() {
    const s = document.getElementById('inputId').value;
    window.location.replace("https://www.google.com/search?q=" + s);
  }

  function clear() {
    <!-- I do not know how to write the code for this part -->
  }
</script>

<input onclick="clear()" type="button">Clear Browsing History</input>
<h1>Search The Web</h1>
<!-- Search Button and input -->
<form id="searchForm" onsubmit="event.preventDefault()">
  <input type="search" name="searchField" id="inputId" placeholder="Search QuickSearch">
  <input type="submit" value="Search" onclick="show()">
</form>

我真的不知道该怎么做
