vue整合SimpleMDE做编辑器

1、安装simplemde

 npm install simplemde --save    //markdown编辑器
 npm install font-awesome --save    //FontAwesome字体图标
 npm install showdown --save    //转换markdown语法
 

2、在conponents下创建以下目录结构

index.vue，进行简单配置。具体配置参照官方文档

<template>
  <div>
    <div style="width:680px;display:inline;float:left" class="simplemde-container">
      <textarea :id="id"/>
    </div>
    <div
      class="simplemde-html"
      style="display: inline;float: left;margin-left: 40px;font-size: 18px;"
      v-html="converterValue"
    ></div>
  </div>
</template>

<script>

import "font-awesome/css/font-awesome.min.css";
import "simplemde/dist/simplemde.min.css";
import SimpleMDE from "simplemde";
import showdown from "showdown";

export default {
  name: "SimplemdeMd",
  props: {
    value: {
      type: String,
      default: ""
    },
    id: {
      type: String,
      required: false,
      default: "markdown-editor-" + +new Date()
    },
    placeholder: {
      type: String,
      default: ""
    }
  },
  data() {
    return {
      simplemde: null,
      hasChange: false,
      converterValue: ""
    };
  },
  watch: {
    value(val) {
      if (val === this.simplemde.value() && !this.hasChange) return;
      this.simplemde.value(val);
    }
  },
  mounted() {
    this.simplemde = new SimpleMDE({
      element: document.getElementById(this.id),
      autofocus: true,
      toolbar: [
        "bold",
        "italic",
        "heading",
        "strikethrough",
        "quote",
        "heading-smaller",
        "heading-bigger",
        "code",
        "quote",
        "unordered-list",
        "ordered-list",
        "clean-block",
        "link",
        "image",
        "table",
        "horizontal-rule",
        "preview",
        "side-by-side",
        "fullscreen",
        "guide"
      ],
      autoDownloadFontAwesome: false,
      spellChecker: false,
      insertTexts: {
        link: ["[", "]( )"]
      },
      placeholder: this.placeholder
    });
    if (this.value) {
      this.simplemde.value(this.value);
    }
    this.simplemde.codemirror.on("change", () => {
      if (this.hasChange) {
        this.hasChange = true;
      }
      this.converterValue = new showdown.Converter().makeHtml(
        this.simplemde.value()
      );
      this.$emit("input", this.simplemde.value());
    });
  },
  destroyed() {
    this.simplemde.toTextArea();
    this.simplemde = null;
  }
};
</script>

<style scoped>
.simplemde-container >>> .CodeMirror {
  min-height: 150px;
  line-height: 20px;
}

.simplemde-container >>> .CodeMirror-scroll {
  min-height: 150px;
}

.simplemde-container >>> .CodeMirror-code {
  padding-bottom: 40px;
}

.simplemde-container >>> .editor-statusbar {
  display: none;
}

.simplemde-container >>> .CodeMirror .CodeMirror-code .cm-link {
  color: #1890ff;
}

.simplemde-container >>> .CodeMirror .CodeMirror-code .cm-string.cm-url {
  color: #2d3b4d;
}

.simplemde-container
  >>> .CodeMirror
  .CodeMirror-code
  .cm-formatting-link-string.cm-url {
  padding: 0 2px;
  color: #e61e1e;
}
.simplemde-container >>> .editor-toolbar.fullscreen,
.simplemde-container >>> .CodeMirror-fullscreen {
  z-index: 1003;
}
.simplemde-html >>> *{
  margin-top: 4px;
  margin-bottom: 4px 
} 
</style>

3、使用

<template>
  <div class="components-container">
    <div class="editor-container">
      <markdown-editor
        id="contentEditor"
        ref="contentEditor"
        v-model="content"
      ></markdown-editor>
    </div>
  </div>
</template>
<script>
import MarkdownEditor from "@/components/MarkdownEditor";

export default {
  components: { MarkdownEditor },
  data () {
    return {
      content: '',
      html: ''
    }
  },
  methods: {
    markdown2Html() {
      import('showdown').then(showdown => {
        const converter = new showdown.Converter()
        this.html = converter.makeHtml(this.content)
      })
    }
  }
};
</script>

具体效果
