解决使用 editor.md 显示网页上md格式乱码

1. 项目需求

最近自己在做项目有一个需求,就是点击发布任务,我们输入的文字可以像markdown一样实现各种符号的输入以及代码格式正确显示。为了完成这个小功能,于是开启了我自己的挖坑路。

1.1 技术需求

首先说明下我自己的技术路线:

SpringBoot + Thymeleaf + html

1.2 安装 editor.md

这里附上官网链接: EditorMD 下载地址

把上面那个项目给下载下来,然后我们根据需求选择我们需要的文件,如下图所示：

如果不想删除其他文件也可以直接把整个文件夹放到你的目录也是可以的，看自己需求了。

1.3 配置 editormd

这里我就用我自己的代码为例作为示范:

这里主要任务就是引入相关css、js文件在上面的代码里面，把这些写上差不多就ok了

1.4 结果展示

然后我们下面展示下我们的结果:

1.5 小问题

有了上面的editor.md 我们发布一条公告试一试:

在网页上显示结果为:

2. 解决方案

显然上面的结果显示不是我们想要的答案,所以我们需要对我们的结果进行转换，下面直接讲做法：

这里我们使用一个开源的js库：showdown.js

官方地址为: Showdown.js

然后引入下面这个静态资源:

<script src="/showdown/1.3.0/showdown.min.js"></script>或者这个

然后再 html最底部加一个这个：

<script>//获取要转换的文字 content 是 div 里面的 idlet text = document.getElementById("content").value;//创建实例let converter = new showdown.Converter();//进行转换let html = converter.makeHtml(text);//展示到对应的地方 $('#content').html(html);//重新渲染到页面上</script>
