插件:
markdown-it
@traptitech/markdown-it-katex
markdown-it-link-attributes
highlight.js
@wangeditor/editor
@wangeditor/editor-for-vue
html-docx-js-typescript

markdown展示组件:

<!-- 展示 后端传来的Markdown格式文字 的组件 --><scriptsetuplang="ts">import MarkdownIt from'markdown-it'import mdKatex from'@traptitech/markdown-it-katex'import mila from'markdown-it-link-attributes'import hljs from'highlight.js'import'highlight.js/styles/default.css';import{ ref, computed }from'vue';const props = defineProps<{markdown: string // 父组件传入要展示/编辑的markdown格式文本
  fontSize?: string
}>()// 设定文字大小const fontSize = computed<string>(()=>{if(props.fontSize){return props.fontSize
  }else{return'16px'}})// 对外暴露innerText,以供复制const showAreaRef =ref()const innerText = computed<string>(()=>{return showAreaRef.value.innerText
})defineExpose({
  innerText
})const mdi =newMarkdownIt({linkify:true,highlight:(code: any,lang: any)=>{if(lang && hljs.getLanguage(lang)){return hljs.highlight(code,{language: lang }).value;}else{return hljs.highlightAuto(code).value;}}})

mdi.use(mila,{attrs:{target:'_blank',rel:'noopener'}})
mdi.use(mdKatex,{blockClass:'katexmath-block rounded-md p-[10px]',errorColor:' #cc0000'})const text = computed<string>(()=>{const value = props.markdown ??''// mdi实例将markdown文本渲染成HTML格式文本return mdi.render(value)})</script><template><!-- 展示状态 --><divclass="show-area"v-html="text"ref="showAreaRef"></div></template><stylescopedlang="scss">.show-area{width: 100%;word-wrap: break-word;font-size:v-bind(fontSize);}</style>

markdown文本放入富文本编辑器、可导出为word组件

<!-- 编辑 后端传来的Markdown格式文字 的组件 --><scriptsetuplang="ts">import MarkdownIt from'markdown-it'import mdKatex from'@traptitech/markdown-it-katex'import mila from'markdown-it-link-attributes'import hljs from'highlight.js'import'highlight.js/styles/default.css';import{ ref, computed, onBeforeUnmount, shallowRef, watch, nextTick }from'vue';// WangEditor 相关import'@wangeditor/editor/dist/css/style.css'import{ Editor, Toolbar }from'@wangeditor/editor-for-vue'//将html转为wordimport{ asBlob }from'html-docx-js-typescript'import{ useWriteStore }from'@/stores'import{ storeToRefs }from'pinia'// 是否要导出文档,监听它,只要值改变就导出const{ isExportDoc }=storeToRefs(useWriteStore())const props = defineProps<{markdown: string // 父组件传入要展示/编辑的markdown格式文本
  title?: string
}>()// markdown-it 相关const mdi =newMarkdownIt({linkify:true,highlight:(code: any,lang: any)=>{if(lang && hljs.getLanguage(lang)){return hljs.highlight(code,{language: lang }).value;}else{return hljs.highlightAuto(code).value;}}})

    valueHtml.value = newValue
  }else{// 传输结束,开启新的一行
    valueHtml.value +='<p>\n</p>'
    ElMessage.success({offset:55,message:'AI撰写完成'})}nextTick(()=>{
    editorRef.value.focus(true)// 在内容末尾focus,nextTick确保在内容加载完成后,才让光标focus到末尾
    editArea.value!.scrollTop = editArea.value!.scrollHeight
  })})// modeconst mode = ref<string>('default')const toolbarConfig ={}const editorConfig ={placeholder:'请输入内容...',scroll:false}// 组件销毁时,也及时销毁编辑器onBeforeUnmount(()=>{const editor = editorRef.value
