理解HTML解析过程

浏览器解析html的过程是：接受网络数据-》将二进制码变成字符-》将字符变为unicode code points.-》tokenizer -》tree constructor -》DOM ready -》Window ready. 前端编程，主要理解的是tree constructor -> dom ready -> window ready的流程。因为在tree constructor的过程中，可能会有动态输出，比如 document.createElement('script'). 动态输出的部分是怎么被解析的呢？动态的script ready和DOM ready和window ready有什么关系,通过以下代码，可以清楚看出浏览器对HTML的加载过程与事件的触发时间。

<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.0.js"></script>

<body>

// This function load dojo resource by creating <script> tag. You can put this function in 3 places to test how browser load JS.
function loadDojo() {
var s = document.createElement('script');
s.src = 'http://ajax.googleapis.com/ajax/libs/dojo/1.8.0/dojo/dojo.js';

document.addEventListener('DOMContentLoaded',

console.log('jQuery:'+!!window.jQuery);

// Place 1.
// You can put function here:

window.addEventListener('load',
function(){
console.log('==============window ready==============');
console.log('dojo:' + !!window.dojo);
console.log('jQuery:'+!!window.jQuery);

// Place 2.
// You can put function here:
// loadDojo();
},
false);

// Place 3.
// You can put function here:
loadDojo();

console.log('=========after creation ============');
console.log('dojo:' + !!window.dojo);
console.log('jQuery:'+!!window.jQuery);
</script>
