BOM 浏览器对象模型

BOM(Browser Object Model,浏览器对象模型)HTML5规范中有一部分涵盖了BOM的主要内容,因为W3C希望将JavaScript在浏览器中最基础的部分标准化。

DOM(Document Object Model,文档对象模型)是HTML和XML文档的编程接口。DOM表示由多层节点构成的文档,通过它开发者可以添加、删除和修改页面的各个部分。DOM现在是真正跨平台、语言无关的表示和操作网页的方式。

DOM1(DOM Level 1)主要定义了HTML和XML文档的底层结构。

DOM2(DOM Level 2)和DOM3(DOM Level 3)在这些结构之上加入更多交互能力,提供了更高级的XML特性。

DOM2和DOM3是按照模块化的思路来制定标准的,每个模块之间有一定关联,但分别针对某个DOM子集。

whatwg标准 和w3c并行开发

和w3c签署的协议,whatwg 开发,w3c联系社区主要是html和dom,将whatwg 作为候选标准

Memorandum of Understanding Between W3C and WHATWG

着手其他标准,living standard(string,fetch,console等)

总的来说主要由w3c规划和制定
