废物不多说，直接上代码

let oldList
let toNodeList = function (arrayOfNodes) {let fragment = document.createDocumentFragment();arrayOfNodes.forEach(function (item) {fragment.appendChild(item.cloneNode());});return fragment.childNodes;};let playLisTemp = [...document.querySelectorAll('.myui-content__operate .btn-warm'),].map((el) => {const a = document.createElement('a');a.innerText = '立即播放';a.href = el.href;return a;});$oldList = toNodeList(playLisTemp);

运行结果如下
