在微信小程序下会用到wxParse这个东西来达到html转换wxml的效果,
taro小程序官方也给出了示例,地址
这里封装成自己的组件:
import Taro, { Component } from "@tarojs/taro" import { View } from "@tarojs/components" import WxParse from ‘../../utils/wxParse/wxParse.js‘ import "../../utils/wxParse/wxParse.scss" export default class ParseComponent extends Component { componentDidMount() {} defaultProps = { mark: "" } render() { if (this.props.mark) { let domText = this.props.mark WxParse.wxParse("domText", "html", domText, this.$scope, 5); } return ( <View> {process.env.TARO_ENV === "weapp" ? ( <View> <import src=‘../../utils/wxParse/wxParse.wxml‘ /> <template is=‘wxParse‘ data=‘{{wxParseData:domText.nodes}}‘ /> </View> ) : ( <View>只在小程序里支持</View> )} </View> ); } }
另外,转化之后的图片地址是相对地址,在小程序中是无法显示的,所以需要到html2json.js文件中加上图片的域名地址:
//对img添加额外数据 if (node.tag === ‘img‘) { node.imgIndex = results.images.length; var imgUrl = ‘域名地址‘ + node.attr.src; if (imgUrl[0] == ‘‘) { imgUrl.splice(0, 1); } imgUrl = wxDiscode.urlToHttpUrl(imgUrl, __placeImgeUrlHttps); node.attr.src = imgUrl; node.from = bindName; results.images.push(node); results.imageUrls.push(imgUrl); }
