Simple HTML to JSON parser use Regexp and String.indexOf
微信建议nodes属性绑定数组，所以htmlParse(html)返回值改成数组 旧版本输出属性名根据微信文档改变,微信文档地址： https://mp.weixin.qq.com/debug/wxadoc/dev/component/rich-text.html
"tag":"root" => "name": "div" "type": "Element" || "Text" => type: "node" || "text" "attributes": {} => attrs: {"class": "parse-*"} // 增加默认class（parse-div,parse-img, parse-a...），可外部修改转换后元素的样式 "content": "content..." => "text": "text..." // 文本节点内容 import htmlParser from "htmlParser" data: { nodes: [] } var html = "<div style='height:10rpx;width: 20rpx;'>1<p>2<br/><a href='http://www.baidu.com'>3</a></p><p>2</p></div>" this.setData({ nodes: htmlParser(this.data.html) })wxml:
