先来看一段代码：

var dom = document.querySelector('body');for(var i in dom){    console.log(i,dom[i])}

可以看到很多，来整理一下，总共有三大类（我自己分的，没有科学依据）

除了一些私有属性、方法（比如a的私有属性href等）和一些空的属性

1. attributes

2. events

3. methods

---

attributes

根据value类型又分为了几个小分类：

1.普通属性

text

link vLink aLink title lang translate truedir hidden falsetabIndex -1accessKey draggable falsespellcheck truecontentEditable inheritisContentEditable falseinnerText imagesFeaturesouterText webkitdropzonenamespaceURI prefix nullinnerHTML outerHTMLshadowRoot nullbaseURI isConnected truebaseURI isConnected truenodeValue nulltextContent

2.样式属性

bgColor

background offsetTop 0offsetLeft 0offsetWidth 1333offsetHeight 50scrollTop 0scrollLeft 0scrollWidth 1333scrollHeight 950clientTop 0clientLeft 0clientWidth 1333clientHeight 50

3.dom操作属性

offsetParent null

localName bodytagName BODYpreviousElementSibling nextElementSiblingchildren firstElementChild lastElementChild childElementCount nodeType 1nodeName BODYownerDocument #documentparentNode parentElement childNodes firstChild lastChild previousSibling nextSibling null

4.其他对象属性

style CSSStyleDeclaration {}

dataset DOMStringMap {}attributes NamedNodeMap {length: 0}

5.我不知道的类型
