大家好，所以在添加文档对象片段时遇到一个奇怪的问题。
总体而言，我正在为艺术家站点进行一些快速修复样式替代。他们有一些下拉菜单，以前的开发人员尝试样式化但没有用。
我正在尝试克隆现有的select并将其放入div包装器中，然后我有一个预先构建的脚本+ CSS来制作自己的样式下拉列表。
不幸的是我遇到了这个！似乎它没有像我期望的那样被解析。
[object DocumentFragment]
这里是相关代码：
const fragment = document.createDocumentFragment();
const selectContainer = document.createElement("div");
const select = document.querySelector("#billing_country");
const selectClone = select.cloneNode(true);
selectContainer.append(selectClone);
selectContainer.id = "custom-select";
fragment.append(selectContainer);
document.querySelector(
"#billing_country"
).parentElement.innerHTML = fragment;
Element.innerHTML设置程序需要一个字符串，而不是节点。
将您的documentFragment附加到该元素中，您可以这样做
element.append( fragment );
const fragment = document.createDocumentFragment();
const selectContainer = document.createElement("div");
const select = document.querySelector("#billing_country");
const selectClone = select.cloneNode(true);
selectContainer.append(selectClone);
selectContainer.id = "custom-select";
fragment.append(selectContainer);
document.querySelector( "#billing_country" ).parentElement
.append( fragment ); // don't use innerHTML here#custom-select {
border: 1px solid red;
}<div id="parent">
<select id="billing_country">
<option>Absurdistan</option>
<option>Atlantis</option>
<option>Borduria</option>
<option>Kambezi</option>
<option>Lugash</option>
</select>
</div>嗯，我仍然不知道为什么DOM似乎不想解析我的对象片段。
我最终还是用字符串文字以旧的方式完成了它。
这里是想要替换选择下拉列表的所有人的完整代码。这将节省您大量的时间。享受！
document.addEventListener("DOMContentLoaded", function () {
console.log("Overrides Loaded");
(function initCustomSelect() {
const elems = [
"#billing_country",
"#billing_state",
"#shipping_country",
"#shipping_state",
".orderby",
];
let match = false;
elems.map(function (elem, index) {
if (document.querySelector(elem)) {
const parent = document.querySelector(elem).parentElement;
const html = parent.innerHTML;
parent.innerHTML = `<div class='custom-select'>${html}</div>`;
match = true;
}
});
if (match) {
formatSelectItems();
}
})()
function formatSelectItems() {

及其CSS样式！

/*the container must be positioned relative:*/
.custom-select {
