简介
cover既然作为能将多种终端的前端代码抽象出来，那么毕竟既有高度的概括性、明确性、简洁性和一致性。这里采用mvp设计模式，将dom树抽离存入View-html中，将计算后的样式View-style中。
<!-- html -->
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Web</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
经过cover入端处理模块=======>
[{
"type": "element",
"tagName": "!doctype",
"attributes": [{
"key": "html",
"value": null
}],
"children": []
}, {
"type": "element",
"tagName": "html",

"children": [{

}, {

"type": "element",
"tagName": "h1",

}]
// 经过cover输出端处理模块输出wxml(wx-get-wxml)=======>
