/* 本下载器可添加抓取规则以支持更多网站
抓取规则示例：
["www.yruan.com", {
bookname() { return document.querySelector('#info > h1:nth-child(1)').innerText.trim() },
author() { return document.querySelector('#info > p:nth-child(2)').innerText.replace(/作\s+者:/, '').trim() },
intro() { return convertDomNode(document.querySelector('#intro > p'))[0] },
linkList() { return document.querySelectorAll('div.box_con div#list dl dd a') },
coverUrl() { return document.querySelector('#fmimg > img').src; },
chapterName: function(doc) { return doc.querySelector('.bookname > h1:nth-child(1)').innerText.trim() },
content: function(doc) { return doc.querySelector('#content') },
}],
抓取规则的 `key` 为该抓取规则适用的网站域名，即 `document.location.host`。
抓取规则的 `value` 一对象，该对象由7个函数组成：
函数名 功能 返回值
bookname() 抓取小说题名 String
author() 抓取小说作者 String
intro() 抓取小说简介 String
linkList() 抓取小说分章链接列表 NodeList
coverUrl() 抓取小说封面图片地址 String
以上5个函数在小说目录页（即按下按钮时的页面）运行。
函数名 功能 返回值
chapterName(doc) 抓取小说章节名 String
content(doc) 抓取小说章节主体部分 Element
以上2个函数在小说章节页运行，输入值 `doc` 为小说章节页的 `document` 。
根据上述要求添加好相应网站抓取规则，并在 `// @match` 中添加相应网站，即可在新网站上使用本下载器。
调试功能：
将 `enableDebug` 变量改为 `true` 可开启调试功能，开启之后可在控制台（console）中访问如下对象：
对象名 类型 功能
rule 变量 当前抓取规则
main(rule) 函数 运行下载器
convertDomNode(node) 函数 输出处理后的txt文本及Dom节点
ruleTest(rule) 函数 测试抓取规则
