uni-app文章详情-富文本展示优雅展示代码块

丈夫欲遂平生志，一载寒窗一举汤。这篇文章主要讲述uni-app文章详情-富文本展示优雅展示代码块相关的知识，希望能为你提供帮助。

在uni-app开发中，开发一个资讯详情页面，详情里包含图片和代码块。这时候用简单的rich-text控件已经不够用了。用官方demo里的html-parser.js也无法很好的展示代码区域。这个时候就要使用官方提供的插件来解决。
官方的这个插件有很多问题。需要使用第3方修复的版本：https://ext.dcloud.net.cn/plugin?id=1279
首先：下载插件：https://ext.dcloud.net.cn/plugin?id=1279
第二步：写代码 demo示例

< template> < div> < u-parse :content="content" @navigate="navigate"> < /u-parse> < /div> < /template> < script> import uParse from "@/components/feng-parse/parse.vue"; //注意：官方提供的示例代码有问题 export default { components: { uParse }, data () { return { article: \'< div> 我是HTML代码< /div> \' } }, methods: { preview(src, e) { // do something }, navigate(href, e) { // do something } } } < /script> < style> @import url("../../components/feng-parse/parse.css"); //注意：官方提供的示例代码有问题 < /style>

我这边具体的业务代码如下：（可以忽略）

< template> < view> < view class="banner"> {{article_detail.title}} < /view> < view class="article-meta"> < text class="article-meta-text article-author"> 作者：{{article_detail.fields.author}}< /text> < /view> < view class="article-content"> < div> < u-parse :content="article_detail.content" @preview="preview" @navigate="navigate" /> < /div> < view class="parse-con"> < u-parse :content="article_detail.content" @navigate="navigate"> < /u-parse> < /view> < view v-if="article_detail.fields.source" class="article-source"> 文章来自：{{article_detail.fields.source}} < /view> < /view> < view class="comment-wrap"> < /view> < /view> < /template> < script> import uParse from "@/components/feng-parse/parse.vue"const FAIL_CONTENT = \'< p> 数据加载中< /p> \'; export default { components: { uParse }, data() { return {article_detail: {}, id: 0 } }, onShareAppMessage() { return { title: this.article_detail.title, path: \'/pages/detail/detail?query=\' + this.id } }, onLoad: function(event) { // 目前在某些平台参数会被主动 decode，暂时这样处理。 try { console.log(\'入参：\' + event.query); this.id = event.query; } catch (error) { console.log(\'异常来了\'); }this.getDetail(); }, onShow: function() { console.log(\'onShow里：\'); console.log(\'id=\' + this.id); // #ifdefMP-BAIDU var zyizurl = getApp().globalData.zyiz_domain + \'/api/Zyiz/Detail/\' + this.id; uni.request({ url: zyizurl, success: (result) => {if (result.statusCode == 200) { console.log("详情结果2："); console.log(result); var article_d = result.data.data; var keyw = article_d.tags + \',\' + article_d.category_name + \',\' + getApp().globalData.keywords; if (article_d.seo_keywords) { keyw = article_d.tags + \',\' + article_d.category_name + \',\' + article_d.seo_keywords; } var zhaiyao = getApp().globalData.description; if (article_d.zhaiyao) { zhaiyao = article_d.zhaiyao; } var img_url = \'http://www.zyiz.net/templates/main_zyiz/images/logo.png\'; if (article_d.img_url) { img_url = article_d.img_url; } var title = article_d.title + \'-\' + article_d.category_name; swan.setPageInfo({ title: title, keywords: keyw, description: zhaiyao, articleTitle: title, releaseDate: article_d.add_time, image: img_url, video: \'\' }); }} }); // #endif}, methods: { getDetail() {var zyizurl = getApp().globalData.zyiz_domain + \'/api/Zyiz/Detail/\' + this.id; uni.request({ url: zyizurl, success: (result) => {if (result.statusCode == 200) { console.log("详情结果："); console.log(result); this.article_detail = result.data.data; }} }); }, navigate(e) { console.log(e) }}}< /script> < style> @import url("../../components/feng-parse/parse.css"); /* #ifndef APP-PLUS */ page { min-height: 100%; }/* #endif */ .baidu-arcontent { width: 98%; }.baidu-arcontent img, .baidu-arcontent image { max-width: 95% !important; mode: aspectFit; }.article-source { padding: 10upx; color: #AAAAAA; }.banner { margin: 10upx; text-align: center; font-size: 40upx; font-weight: bold; }.article-content image { width: 96%; }.banner-img { flex: 1; }.title-area { position: absolute; left: 30upx; right: 30upx; bottom: 30upx; z-index: 11; }.title-text { font-size: 32upx; font-weight: 400; line-height: 42upx; lines: 2; color: #ffffff; overflow: hidden; }.article-meta { padding: 20upx 30upx; flex-direction: row; align-items: center; justify-content: flex-start; }.article-meta-text { color: gray; }.article-text { font-size: 26upx; line-height: 50upx; margin: 0 20upx; }.article-author { font-size: 30upx; }.article-time { font-size: 30upx; }.article-content { font-size: 30upx; padding: 0 30upx; margin-bottom: 30upx; overflow: hidden; } < /style>
