Vue实现MakeDown编辑器

如题，我们在Vue里实现MarkDown编辑器，相对于富文本，MarkDown更加的方便快捷，所以就有了这篇文章，可以让我们在vue里面使用MarkDown编辑器编辑排版文本内容

做好之后的效果图（MarkDown编辑器支持vue的不少，我这里仅供参考）

接下来讲解下如何安装配置这个MarkDown编辑器

首先安装 markdown 编辑器

npm install zx-markdown-editor

安装完成之后，新建位置存放markdown js脚本，js脚本和vue需要在同级目录

这是楼主的目录结构，具体目录结构可以查看代码部分，或者自定义目录位置

vabMarkdownEditor.JS 脚本内容

import ZxMarkdownEditor from "./markdown";

export default ZxMarkdownEditor;
if (typeof window !== "undefined" && window.Vue) {
    window.Vue.component("zx-markdown-editor", ZxMarkdownEditor);
}

这里是属于MarkDown的编辑配置部分

markdown.vue的脚本部分

<template>
    <div class="simple-mde" :class="classes">
        <textarea ref="mde"></textarea>
    </div>
</template>
<script>
    import "font-awesome/css/font-awesome.min.css";
    import SimpleMDE from "simplemde";
    import "simplemde/dist/simplemde.min.css";
    import marked from "marked";
    import "github-markdown-css/github-markdown.css";
    export default {
        name: "markdown",
        props: {
            value: {
                type: String,
                default: "",
            },
            border: {
                type: Boolean,
                default: false,
            },
            config: {
                type: Object,
                default: () => ({}),
            },
        },
        data() {
            return {
                mde: null,
                defaultConfig: {},
            };
        },
        computed: {
            classes() {
                return [
                    {
                        "i-mde-no-border": !this.border,
                    },
                ];
            },
        },
        mounted() {
            this.init();
        },
        beforeDestroy() {
            this.mde = null;
        },
        methods: {
            init() {
                const config = Object.assign({}, this.defaultConfig, this.config);
                this.mde = new SimpleMDE({
                    ...config,
                    initialValue: this.value,
                    element: this.$refs.mde,
                    autoDownloadFontAwesome: false,
                });
                this.mde.codemirror.on("change", () => {
                    this.$emit("input", this.mde.value());
                    this.$emit("on-change", this.mde.value());
                    const mdHtml = marked(this.mde.value() || "", {
                        renderer: new marked.Renderer(),
                        gfm: true,
                        tables: true,
                        breaks: false,
                        pedantic: false,
                        sanitize: false,
                        smartLists: true,
                        smartypants: false,
                    });
                    this.$emit(
                        "show-html",
                        '<div class="markdown-body" >' + mdHtml + "</div>"
                    );
                });
            },
            add(val) {
                if (this.mde) {
                    this.mde.value(this.value + val);
                }
            },
            replace(val) {
                if (this.mde) {
                    this.mde.value(val);
                }
            },
        },
    };
</script>

页面代码部分，放到新建的vue页面，或者是嵌入具体的页面位置

<template>
    <div class="markdown-editor-container">
        <el-row :gutter="20">
            <el-col :xs="24" :sm="24" :md="24" :lg="12" :xl="12">
                <vab-markdown-editor
                        ref="mde"
                        v-model="value"
                        @show-html="handleShowHtml"
                ></vab-markdown-editor>
            </el-col>
            <el-col :xs="24" :sm="24" :md="24" :lg="12" :xl="12">
                <el-card shadow="hover">
                    <div slot="header">
                        <span>实时预览部分</span>
                    </div>
                    <div v-html="html"></div>
                </el-card>
            </el-col>
        </el-row>
    </div>
</template>

<script>
//这里引入我们的js文件，路径可以自定义
    import VabMarkdownEditor from "../../components/markdown/vabMarkdownEditor";

    export default {
        name: "markDown",
        components: { VabMarkdownEditor },
        data() {
            return {
            //上班是用来编辑的内容，下边是实时预览的信息值
                value: "# vue-admin-beautiful",
                html: '<h1 id="vue-admin-beautiful">vue-admin-beautiful</h1>',
            };
        },
        methods: {
        //用来把编写的文本内容实时转换到右侧的显示区域
            handleShowHtml(html) {
                this.html = html;
            },
        },
    };
</script>

然后运行进入页面，输入MarkDown格式的文本，就可以在右边看到渲染后的格式文本
