安装 mavon-editor

 npm install mavon-editor --save 

一、vue中，按照官网，全局注册mavonEditor报错

参考mavonEditor的github地址给出的全局注册 use 示例，报错：
Unknown custom element: <mavon-editor> - did you register the component correctly?

mavonEditor.js

import Vue from "vue";
import { mavonEditor } from "mavon-editor";
import "mavon-editor/dist/css/index.css";
Vue.use(mavonEditor);

二、错误解决

用component 全局注册mavonEditor, mavonEditor.js

import Vue from "vue";
import { mavonEditor } from "mavon-editor";
import "mavon-editor/dist/css/index.css";
Vue.component("mavon-editor", mavonEditor);

在main.js中引入上述文件。

三、在组件中使用

test.vue

<template>
  <div class="markdown-container">
    <div class="container">
      <div class="title">编辑器</div>
      <mavon-editor
        v-model="content"
        ref="md"
        @imgAdd="$imgAdd"
        @change="change"
        style="min-height: 600px"
      />
      <el-button class="editor-btn" type="primary" @click="submit"
        >提交</el-button
      >
    </div>
  </div>
</template>
<script>
//该组件中注释掉的代码为局部注册的方式。
// import { mavonEditor } from "mavon-editor";
// import "mavon-editor/dist/css/index.css";
import axios from "axios";
export default {
  data: function() {
    return {
      content: "",
      html: "",
      configs: {}
    };
  },
  // components: {
  //   mavonEditor
  // },
  methods: {
    // 将图片上传到服务器，返回地址替换到md中
    $imgAdd(pos, $file) {
      var formdata = new FormData();
      formdata.append("file", $file);
      //将下面上传接口替换为你自己的服务器接口
      axios({
        url: "/common/upload",
        method: "post",
        data: formdata,
        headers: { "Content-Type": "multipart/form-data" }
      }).then(url => {
        this.$refs.md.$img2Url(pos, url);
      });
    },
    change(value, render) {
      // render 为 markdown 解析后的结果
      this.html = render;
    },
    submit() {
      console.log(this.content);
      console.log(this.html);
      this.$message.success("提交成功！");
    }
  }
};
</script>
<style lang="scss">
.markdown-container {
  .editor-btn {
    margin-top: 20px;
  }
  .title {
    padding-bottom: 30px;
    text-align: center;
    font-size: 20px;
    letter-spacing: 1px;
    color: #333;
    font-weight: 600;
  }
}
</style>
