本文章向大家介绍一个html标签到底包含了多少信息(1),主要包括一个html标签到底包含了多少信息(1)使用实例、应用技巧、基本知识点总结和需要注意事项,具有一定的参考价值,需要的朋友可以参考一下。

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 true
dir
hidden false
tabIndex -1
accessKey
draggable false
spellcheck true
contentEditable inherit
isContentEditable false
innerText
images
Features
outerText

prefix null
innerHTML
outerHTML
shadowRoot null
baseURI
isConnected true
baseURI http://192.168.1.86/bootstrap/index.html?#1
isConnected true
nodeValue null
textContent

2.样式属性

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

3.dom操作属性

offsetParent null
localName body
tagName BODY
previousElementSibling
nextElementSibling
children
firstElementChild
lastElementChild
childElementCount
nodeType 1
nodeName BODY
ownerDocument #document
parentNode
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

ELEMENT_NODE 1
ATTRIBUTE_NODE 2
TEXT_NODE 3
CDATA_SECTION_NODE 4
ENTITY_REFERENCE_NODE 5
ENTITY_NODE 6
PROCESSING_INSTRUCTION_NODE 7
COMMENT_NODE 8
DOCUMENT_NODE 9
DOCUMENT_TYPE_NODE 10
DOCUMENT_FRAGMENT_NODE 11
NOTATION_NODE 12
DOCUMENT_POSITION_DISCONNECTED 1
DOCUMENT_POSITION_PRECEDING 2
DOCUMENT_POSITION_FOLLOWING 4
DOCUMENT_POSITION_CONTAINS 8
DOCUMENT_POSITION_CONTAINED_BY 16
DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC 32
