SunnyRun！2023-10-07 16:57

欢迎点击领取 -《前端面试题进阶指南》：前端登顶之巅-最全面的前端知识点梳理总结

*分享一个使用比较久的🪜

简介

1、安装：pnpm add tinymce / pnpm add @tinymce/tinymce-vue ===> Vue3 + tinymce + @tinymce/tinymce-vue

2、功能实现图片上传、基金卡片插入、收益卡片插入、源代码复用、最大长度限制、自定义表情包插入、文本内容输入、预览等功能

代码展示

在components文件下创建TinymceEditor.vue文件作为公共组件

创建wordlimit.ts文件，作为限制字符的触发条件

js 复制代码 
import tinymce from 'tinymce/tinymce'
import { ElMessage } from 'element-plus'
import { sumLetter } from '@/utils/utilTool'

tinymce.PluginManager.add('wordlimit', function (editor): any {
  const pluginName = '字数限制'
  const app = tinymce.util.Tools.resolve('tinymce.util.Delay')
  const Tools = tinymce.util.Tools.resolve('tinymce.util.Tools')
  const wordlimit_event = editor.getParam('ax_wordlimit_event', 'SetContent Undo Redo Keyup input paste')
  const options = editor.getParam('wordlimit', {}, 'object')
  let close = null

  const toast = function (message) {
    close && close.close()
    close = ElMessage.error(message)
    return
  }

  // 默认配置
  const defaults = {
    spaces: false, // 是否含空格
    isInput: false, // 是否在超出后还可以输入
    maxMessage: '超出最大输入字符数量！',
    changeCallback: () => {}, // 自定义的回调方法
    changeMaxCallback: () => {},
    toast // 提示弹窗
  }

  class WordLimit {
    constructor(editor, options) {
      options = Tools.extend(defaults, options)
      let preCount = 0
      let _wordCount = 0
      let oldContent = editor.getContent()
      const WordCount = editor.plugins.wordcount

      editor.on(wordlimit_event, function (e) {
        const content = editor.getContent() || e.content || ''
        if (!options.spaces) {
          _wordCount = WordCount.body.getCharacterCount()
        } else {
          _wordCount = WordCount.body.getCharacterCountWithoutSpaces()
        }
        options.changeCallback({
          ...options,
          editor,
          num: _wordCount,
          content,
          ...sumLetter(content)
        })
        if (_wordCount > options.max) {
          preCount = _wordCount
          if (options.isInput == !1) {
            editor.setContent(oldContent)
            if (!options.spaces) {
              _wordCount = WordCount.body.getCharacterCount()
            } else {
              _wordCount = WordCount.body.getCharacterCountWithoutSpaces()
            }
          }
          editor.getBody().blur()
          editor.fire('wordlimit', {
            maxCount: options.max,
            wordCount: _wordCount,
            preCount: preCount,
            isPaste: e.type === 'paste' || e.paste || false
          })
          toast('最多只能输入' + options.max + '个字')
        }
        oldContent = editor.getContent()
      })
    }
  }

  const setup = function () {
    if (!options && !options.max) return false
    if (!editor.plugins.wordcount) return toast('请先在tinymce的plugins配置wordlimit之前加入wordcount插件')
    app.setEditorTimeout(
      editor,
      function () {
        const editDom = editor.getContainer()
        const wordNum: any = editDom.querySelector('button.tox-statusbar__wordcount')
        const statusbarpath: any = editDom.querySelector('.tox-statusbar__path')
        statusbarpath ? statusbarpath.remove() : void null
        if (wordNum?.innerText?.indexOf('字符') == -1) wordNum.click()
        new WordLimit(editor, options)
      },
      300
    )
  }

  setup()

  return {
    getMetadata: function () {
      return {
        name: pluginName
      }
    }
  }
})
使用
js 复制代码 
<template>
  <div class="post_contaniner">
    <div style="width: 100%">
      <TinymceEditor v-model="content" @input="inputContent" :wordlimit="{ max: 300 }" />
    </div>
  </div>
</template>

<script lang="ts" setup>
import { ref } from 'vue'

const content = ref('Hello World')

const inputContent = (newVal) => {
  console.log(newVal)
  content.value = newVal
}
</script>

<style scoped lang="scss">
.post_contaniner {
  .right {
    flex: 1;
    box-shadow: 0 1px 10px 3px #dbdbdb;
    margin-right: 10px;
    padding: 10px;
    box-sizing: border-box;
  }
}
</style>
