我已經開始快速練習在 JS 中使用本地存儲/會話存儲，我的 LoadFromStorage 函數似乎有問題。每次調用控制臺日志時，“replaceNode”都不是函數。window.onload = function() {  document.getElementById('btnAdd').onclick = function() {    localStorage.setItem(document.getElementById("toStorageKey").value,      document.getElementById("toStorageValue").value);    LoadFromStorage();  }  document.getElementById('btnRemove').onclick = function() {    localStorage.removeItem(document.getElementById('toStorageKey').value);    LoadFromStorage();  }  document.getElementById('btnClear').onclick = function() {    localStorage.clear();    LoadFromStorage();  }  function LoadFromStorage() {    var storageDiv = document.getElementById('storage');    var tbl = document.createElement('table');    tbl.id = "storageTable";    if (localStorage.length > 0) {      for (var i = 0; i < localStorage.length; i++) {        var row = document.createElement("tr");        var key = document.createElement("td");        var val = document.createElement('td');        key.innerText = localStorage.key(i);        val.innerText = localStorage.getItem(key.innerText);        row.appendChild(key);        row.appendChild(val);        tbl.appendChild(row);      }    } else {      var row = document.createElement('tr');      var col = document.createElement('td');      col.innerText = 'No data in local storage.';      row.appendChild(col);      tbl.appendChild(row);    }    if (document.getElementById('storageTable')) {      document.getElementById('storageTable').replaceNode(tbl);    } else {      storageDiv.appendChild(tbl);    };  };}section {  margin-top: 15px;}<section>  Key: <input type="text" id="toStorageKey"><br> Value: <input type="text" id="toStorageValue"><br></section><section>  <button type="button" id="btnAdd">Add to storage</button>  <button type="button" id="btnRemove">Remove from storage</button>  <button type="button" id="btnClear">Clear storage</button></section><div id="storage">  <p>Current Storage Contents</p></div>
