cloneNode cloneNode是用于克隆节点的,相比直接调用createElement创建DOM元素而言,它所花费的开销会更小些,就好比:读书的时候,抄作业要比做作业的容易的多。...举个栗子: var li = document.createElement('li'); for (t = 0; t < num; t++) { var cloneLi = li.cloneNode...从结果中看出,cloneNode虽然比createElement快,但是还是不。那么还有没有更快的方式去创建DOM元素呢?...考虑这个因素,我们可以结合cloneNode和DocumentFragment在去创建DOM元素并插入到文档: var fragment = document.createDocumentFragment...(); var li = document.createElement('li'); for (t = 0; t < num; t++) { var cloneLi = li.cloneNode(
node.cloneNode() 提到克隆节点,我们最先能想到的肯定是 node.cloneNode() 方法。...语法 其语法如下: let cloneNode = targetNode.cloneNode(deep); cloneNode 最终克隆生成的节点副本。...div> const target = document.querySelector(".body"); const cloneNode1...= target.cloneNode(); console.log("cloneNode1.outerHTML\n\n",cloneNode1.outerHTML);...const cloneNode2 = target.cloneNode(true); console.log("cloneNode2.outerHTML\n\n", cloneNode2

div节点会被添加到#ul上,但是sel.添加了div,所以#ul没有div节点 sel.appendChild(div); //将原来div的位置 添加到 #sel中,原先的会消失 //var cloneNode...= div.cloneNode(true); //cloneNode 生成的克隆节点, div被克隆的节点, //cloneNode.innerText = 'test'; //sel.appendChild...(cloneNode); //克隆解决原节点转移位置 3.replaceChild 替换子节点 var div = document.createElement('div'); div.innerText

找到了页面相关的js文件,搜索MutationObserver,最后发现一个这样的函数: function observeSelector(e) { if (e) { var t = e.cloneNode..., i = Array.prototype.slice.call(r.removedNodes)[0]; if (o === e) { var a = t.cloneNode...n.replaceChild(a, e), e = a } else i === e && (e = e.cloneNode...因为这是最原始的节点了 // 如果直接拿element去replace只能拿到具有最新属性的节点 const newClonedNode = element.cloneNode(...target就是当前元素 if (currentTarget === element) { const replaceNode = newClonedNode.cloneNode
我们使用以下方法来实现,参考代码: 代码实现 // 复制一个节点追加给另外一个节点 var shan = document.getElementById("north").childNodes[1]; // cloneNode...参数为 true 为深拷贝 var copy_li = shan.cloneNode(true); var south = document.getElementById("south"); south.appendChild
