1.Vue显示markdown的html页面

1.1 mark编辑

  • 下载包

    npm install mavon-editor --save
    
  • 使用在main.js中 引入

    import mavonEditor from ‘mavon-editor‘
    import ‘mavon-editor/dist/css/index.css‘
    Vue.use(mavonEditor)
    
  • 在子组建使用

    • html中

      <FormItem>
                  <mavon-editor :style="{ zIndex: ‘0‘,width:‘54rem‘}" ref="md" :toolbars="markdownOption" v-model="formInline.content" @imgAdd="imgAdd" @imgDel="imgDel"/>
                </FormItem>
      # 这里绑定imgAdd为添加图片,为访问后台,添加图片,后台返回对应url
      # imgDel为删除图片,回掉函数去访问后台删除对应函数。
      
    • js中

    // data 中添加markdown要求功能
    markdownOption: {
            bold: true, // 粗体
            italic: true, // 斜体
            header: true, // 标题
            underline: true, // 下划线
            mark: true, // 标记
            superscript: true, // 上角标
            quote: true, // 引用
            ol: true, // 有序列表
            link: true, // 链接
            imagelink: true, // 图片链接
            help: true, // 帮助
            code: true, // code
            subfield: true, // 是否需要分栏
            fullscreen: true, // 全屏编辑
            readmodel: true, // 沉浸式阅读
            /* 1.3.5 */
            undo: true, // 上一步
            trash: true, // 清空
            save: true, // 保存(触发events中的save事件)
            /* 1.4.2 */
            navigation: true // 导航目录
          },
    // methods中定义方法
    imgAdd (pos, $file) {
    			// $file 为文件
          // pos 为插入图片索引位置,这里把图片路径放在一个list中也就是img_file
          console.log($file)
          // 第一步.将图片上传到服务器.
          var formdata = new FormData()
          formdata.append(‘image‘, $file)
          this.img_file[pos] = $file
          console.log(this.$http.defaults.baseURL + ‘/upload/content/picture‘)
          axios({
            // 请求地址
            url: this.$http.defaults.baseURL + ‘/upload/content/picture‘,
            method: ‘post‘,
            data: formdata,
            headers: { ‘Content-Type‘: ‘multipart/form-data‘ }
          }).then((data) => {
            // console.log(JSON.stringify(url))
            // 第二步.将返回的url替换到文本原位置![...](./0) -> ![...](url)
            /**
             * $vm 指为mavonEditor实例,可以通过如下两种方式获取
             * 1.  通过引入对象获取: `import {mavonEditor} from ...` 等方式引入后,`$vm`为`mavonEditor`
             * 2. 通过$refs获取: html声明ref : `<mavon-editor ref=md ></mavon-editor>,`$vm`为 `this.$refs.md`
             * 3. 由于vue运行访问的路径只能在static下,so,我就把图片保存到它这里了
             */
            this.$refs.md.$img2Url(pos, data.data.result.urlpath)
          })
        },
    // 这里是做一个列表删除。
    imgDel (pos) {
          delete this.img_file[pos]
        },
    

1.2 markdown实现html显示

  • 导包

    npm install highlight.js --save
    npm install marked --save
    
  • main.js引入

    // 代码高亮
    import hljs from ‘highlight.js‘
    Vue.directive(‘highlight‘, (el) => {
      let blocks = el.querySelectorAll(‘pre code‘)
      blocks.forEach((block) => {
        hljs.highlightBlock(block)
      })
    })
    
  • 组建中使用

    <div class="passage">
    			// v-highlight 代码高亮, 绑定 content
          <div v-highlight v-html="content" class="content"></div>
        </div>
    <script>
    import marked from ‘marked‘
    ...
    // 通过marked将返回Markdown文本转换html
    this.content = marked(mkdContent)
    </script>
    
    
  • 下面是markdown的css样式

    <style>
    h1, h2, h3, h4 {

      font-weight: 400;
