1.节点查找

document.getElementById，document.getElementByTagName，document.getElementByName ，- document.getElementByClassName
document.querySelector() 参数为选择器
document.forms 选取页面中的所有表单元素

2.增加节点

增加节点前必须先使用document.createElement()创建元素节点，参数为标签名

m.appendChild(n) 为m元素在末尾添加n节点
m.insertBefore(k,n) 在m元素的k节点前添加n节点

3.删除节点

m.removeChild(n)删除m元素中的n节点
m.replaceChild(k,n)用n节点取代m元素中的k节点

4.复制节点

m.cloneChild() 复制m节点，并将复制出来的节点作为返回值
参数为true时，则将m元素的后代元素也一并复制。否则，仅复制m元素本身
