Vue3项目中集成最强的tinymce富文本编辑器

前言

tinymce是目前公认的最好的富文本编辑器。本篇文章将详细说明在vue3项目中如何集成tinymce，并将 tinymce封装成组件使用

最终效果

正文

1. 安装依赖,

这里我们使用了tinymce5，最新已经到tinymce6了。不同版本之间插件上会有差异

npm install tinymce@5.10.2

2. 安装汉化包

我们在 vue3 项目的public/resource/ 目录下创建文件夹 tinymce，在tinymce下再创建 langs文件夹用来存放语言汉化包

我们将 这个中文包https://gitee.com/shuiche/tinymce-vue3/blob/master/langs/zh_CN.js下载后放到langs文件夹下

3. 迁移ui皮肤文件

我们在 node_modules/tinymce 中找到 skins 文件夹，将其复制到 public/resource/tinymce/ 里

4. 封装组件

在src/components/ 下新建 Tinymce 文件夹。在 Tinymce/ 文件夹下新建3个文件： helper.js , tinymce.js, Tinymce.vue

内容分别是：

helper.js

// ==========helper.js==========
const validEvents = [
  'onActivate',
  'onAddUndo',
  'onBeforeAddUndo',
  'onBeforeExecCommand',
  'onBeforeGetContent',

  'onVisualAid'
]

const isValidKey = (key) => validEvents.indexOf(key) !== -1

export const bindHandlers = (initEvent, listeners, editor) => {
  Object.keys(listeners)
    .filter(isValidKey)
    .forEach((key) => {
      const handler = listeners[key]
      if (typeof handler === 'function') {
        if (key === 'onInit') {
          handler(initEvent, editor)
        } else {
          editor.on(key.substring(2), (e) => handler(e, editor))
        }
      }
    })
}

<style lang="scss" scoped>
.prefixCls{
    position: relative;
    line-height: normal;
}
textarea {
    z-index: -1;
    visibility: hidden;
}
</style>

在Tinymce中引入了两个外部函数和一个hook，具体内容是：

// ==== isNumber  函数====
const toString = Object.prototype.toString
export function is (val, type) {
  return toString.call(val) === `[object ${type}]`
}
export function isNumber (val) {
  return is(val, 'Number')
}


// ==== buildShortUUID  函数====
export function buildShortUUID (prefix = '') {
    const time = Date.now()
    const random = Math.floor(Math.random() * 1000000000)
    unique++
    return prefix + '_' + random + unique + String(time)
}


// ==== onMountedOrActivated  hook====
import { nextTick, onMounted, onActivated } from 'vue'
export function onMountedOrActivated (hook) {
  let mounted
  onMounted(() => {
    hook()
    nextTick(() => {
      mounted = true
    })
  })
  onActivated(() => {
    if (mounted) {
      hook()
    }
  })
}

使用组件

使用时非常简单,我们用 v-model 和 @change 即可使用。

 <Tinymce v-model="content" @change="handleChange" width="100%" />

// ......

let content = ref('')
function handleChange (item) {
    console.log('change', item)
}
