markdown 写技术博客的必须品。这里记录下 vue 中使用 tui-editor 的过程

代码: https://github.com/nhn/tui.editor

preview: https://ui.toast.com/tui-editor

操作一波

npm install tui-editor

安装好后,先定义一个组件,我们在组件里组织 markdown 编辑器相关的逻辑。

那么就在 src/components/ 下吧。

src/components/MarkdownEditor/index.vue

<template>
  <div :id="id" />
</template>

<script>

import 'codemirror/lib/codemirror.css' // codemirror
import 'tui-editor/dist/tui-editor.css' // editor ui
import 'tui-editor/dist/tui-editor-contents.css' // editor content

import Editor from 'tui-editor'

const defaultOptions = {
  minHeight: '200px',
  previewStyle: 'vertical',
  useCommandShortcut: true,
  useDefaultHTMLSanitizer: true,
  usageStatistics: false,
  hideModeSwitch: false,
  toolbarItems: [
    'heading',
    'bold',
    'italic',
    'strike',
    'divider',
    'hr',
    'quote',
    'divider',
    'ul',
    'ol',
    'task',
    'indent',
    'outdent',
    'divider',
    'table',
    'image',
    'link',
    'divider',
    'code',
    'codeblock'
  ]
}

export default {
  name: 'MarkdownEditor',
  props: {
    value: {
      type: String,
      default: ''
    },
    id: {
      type: String,
      required: false,
      default() {
        return 'markdown-editor-' + +new Date() + ((Math.random() * 1000).toFixed(0) + '')
      }
    },
    options: {
      type: Object,
      default() {
        return defaultOptions
      }
    },
    mode: {
      type: String,
      default: 'markdown'
    },
    height: {
      type: String,
      required: false,
      default: '300px'
    },
    language: {
      type: String,
      required: false,
      default: 'en_US' // https://github.com/nhnent/tui.editor/tree/master/src/js/langs
    }
  },
  data() {
    return {
      editor: null
    }
  },
  computed: {
    editorOptions() {
      const options = Object.assign({}, defaultOptions, this.options)
      options.initialEditType = this.mode
      options.height = this.height
      options.language = this.language
      return options
    }
  },
  watch: {
    value(newValue, preValue) {
      if (newValue !== preValue && newValue !== this.editor.getValue()) {
        this.editor.setValue(newValue)
      }
    },
    language(val) {
      this.destroyEditor()
      this.initEditor()
    },
    height(newValue) {
      this.editor.height(newValue)
    },
    mode(newValue) {
      this.editor.changeMode(newValue)
    }
  },
  mounted() {
    this.initEditor()
  },
  destroyed() {
    this.destroyEditor()
  },
  methods: {
    initEditor() {
      this.editor = new Editor({
        el: document.getElementById(this.id),
        ...this.editorOptions
      })
      if (this.value) {
        this.editor.setValue(this.value)
      }
      this.editor.on('change', () => {
        this.$emit('input', this.editor.getValue())
      })
    },
    destroyEditor() {
      if (!this.editor) return
      this.editor.off('change')
      this.editor.remove()
    },
    setValue(value) {
      this.editor.setValue(value)
    },
    getValue() {
      return this.editor.getValue()
    },
    setHtml(value) {
      this.editor.setHtml(value)
    },
    getHtml() {
      return this.editor.getHtml()
    }
  }
}
</script>

在项目中使用,比如 /src/views/blog/create.vue

<template>
  <div class="container">
    <markdown-editor ref="markdownEditor" v-model="content" :options="{hideModeSwitch:true, previewStyle:'tab'}" height="200px" />
  </div>
</template>

<script>
import MarkdownEditor from '@/components/MarkdownEditor'

export default {
  name: 'blog.create',
  components: {
    MarkdownEditor
  },
  data() {
    return {
      content: 'tuieditor富文本编辑器初始值'
    }
  },
  computed: {
  },
  mounted() {
  },
  methods: {
  }
}
</script>

npm run dev 下,到此,基本的 markdown 功能渲染出来了。这个还是有瑕疵。去弄个国产的,另外一款。
