您可以通过将每个输入框的 `oninput` 事件绑定到 `searchDatabase()` 函数来实现四个输入框都能搜索相同的数据列表。下面是修改后的代码：

<input type="text" id="searchInput" oninput="searchDatabase()" placeholder="武器">
<input type="text" id="1" oninput="searchDatabase()" placeholder="武器">
<input type="text" id="2" oninput="searchDatabase()" placeholder="武器">
<input type="text" id="3" oninput="searchDatabase()" placeholder="武器">
<div id="searchResult"></div>

<script>
  // 您的数据列表
  var arr_YXwuqi = [
    ["亘古之守望", "凯旋骑士", "天堂之刃", "天堂之刃★", "弗鲁梅格之剑", "战场余晖", "星辰之剑", "红辰光巨剑", "红辰光巨剑★", "红长剑★", "通魔战刃", "鱼肠剑"],
    ["不朽巨人", "创世巨人", "屠戮角斗斧", "帝王战斧", "泣血巨人", "狂魔之斧", "皇族长柄斧", "红角斗士之斧★", "红雷矢巨斧", "红雷矢巨斧★", "裂狱", "黄昏"]
  ];

  function searchDatabase() {
    // 获取输入框的值
    var keyword = document.getElementById("searchInput").value;

    // 在数据列表中搜索匹配的数据
    var searchResults = [];
    for (var i = 0; i < arr_YXwuqi.length; i++) {
      for (var j = 0; j < arr_YXwuqi[i].length; j++) {
        if (arr_YXwuqi[i][j].includes(keyword)) {
          searchResults.push(' ' + arr_YXwuqi[i][j]);
        }
      }
    }

    // 显示搜索结果
    var searchResultElement = document.getElementById("searchResult");
    if (searchResults.length > 0) {
      searchResultElement.innerHTML = "搜索结果：" + generateClickableResults(searchResults);
    } else {
      searchResultElement.innerHTML = "未找到匹配的数据";
    }
  }

  function generateClickableResults(results) {
    var clickableResults = "";
    for (var i = 0; i < results.length; i++) {
      clickableResults += "<span onclick='fillInput(\"" + results[i] + "\")'>" + results[i] + "</span>";
    }
    return clickableResults;
  }

  function fillInput(value) {
    document.getElementById("searchInput").value = value;
  }
</script>

这样，四个输入框都能实现与 `id="searchInput"` 的输入框相同的搜索功能，并且它们搜索的都是同一个数据列表。
