vue中引入Tinymce富文本编辑器

中文文档地址：http://tinymce.ax-z.cn/configure/integration-and-setup.php

最近想在项目上引入一个富文本编辑器，之前引入过summernote，感觉并不太适合vue使用，

然后在网上查了查，vue中使用Tinymce比较适合，

首先，我们在vue项目的components文件夹中加入如下几个文件

首先看一下Tinymce/dynamicLoadScript.js的内容：

let callbacks = []

function loadedTinymce() {
  // to fixed https://github.com/PanJiaChen/vue-element-admin/issues/2144
  // check is successfully downloaded script
  return window.tinymce
}

const dynamicLoadScript = (src, callback) => {
  const existingScript = document.getElementById(src)
  const cb = callback || function() {}

  if (!existingScript) {
    const script = document.createElement('script')
    script.src = src // src url for the third-party library being loaded.
    script.id = src
    document.body.appendChild(script)
    callbacks.push(cb)
    const onEnd = 'onload' in script ? stdOnEnd : ieOnEnd
    onEnd(script)
  }

  if (existingScript && cb) {
    if (loadedTinymce()) {
      cb(null, existingScript)
    } else {
      callbacks.push(cb)
    }
  }

  function stdOnEnd(script) {
    script.onload = function() {
      // this.onload = null here is necessary
      // because even IE9 works not like others
      this.onerror = this.onload = null
      for (const cb of callbacks) {
        cb(null, script)
      }
      callbacks = null
    }
    script.onerror = function() {
      this.onerror = this.onload = null
      cb(new Error('Failed to load ' + src), script)
    }
  }

  function ieOnEnd(script) {
    script.onreadystatechange = function() {
      if (this.readyState !== 'complete' && this.readyState !== 'loaded') return
      this.onreadystatechange = null
      for (const cb of callbacks) {
        cb(null, script) // there is no way to catch loading errors in IE8
      }
      callbacks = null
    }
  }
}

export default dynamicLoadScript

再来看一下Tinymce/components/EditorImage.vue中的内容

<template>
  <div class="upload-container">
    <el-button :style="{background:color,borderColor:color}" icon="el-icon-upload" size="mini" type="primary" @click=" dialogVisible=true">
      upload
    </el-button>
    <el-dialog :visible.sync="dialogVisible">

        :file-list="fileList"
        :show-file-list="true"
        :on-remove="handleRemove"
        :on-success="handleSuccess"
        :before-upload="beforeUpload"
        class="editor-slide-upload"
        action="https://httpbin.org/post"
        list-type="picture-card"
      >
        <el-button size="small" type="primary">
          Click upload
        </el-button>
      </el-upload>
      <el-button @click="dialogVisible = false">
        Cancel
      </el-button>
      <el-button type="primary" @click="handleSubmit">
        Confirm
      </el-button>
    </el-dialog>
  </div>
</template>

<script>
// import { getToken } from 'api/qiniu'

export default {
  name: 'EditorSlideUpload',
  props: {
    color: {
      type: String,
      default: '#1890ff'
    }
  },
  data() {
    return {
      dialogVisible: false,
      listObj: {},
      fileList: []
    }
  },
  methods: {
    checkAllSuccess() {
      return Object.keys(this.listObj).every(item => this.listObj[item].hasSuccess)
    },
    handleSubmit() {
      const arr = Object.keys(this.listObj).map(v => this.listObj[v])
      if (!this.checkAllSuccess()) {
        this.$message('Please wait for all images to be uploaded successfully. If there is a network problem, please refresh the page and upload again!')
        return
      }
      this.$emit('successCBK', arr)
      this.listObj = {}
      this.fileList = []
      this.dialogVisible = false
    },
    handleSuccess(response, file) {
      const uid = file.uid
      const objKeyArr = Object.keys(this.listObj)
      for (let i = 0, len = objKeyArr.length; i < len; i++) {
        if (this.listObj[objKeyArr[i]].uid === uid) {
          this.listObj[objKeyArr[i]].url = response.files.file
          this.listObj[objKeyArr[i]].hasSuccess = true
          return
        }
      }
    },
    handleRemove(file) {
      const uid = file.uid
      const objKeyArr = Object.keys(this.listObj)
      for (let i = 0, len = objKeyArr.length; i < len; i++) {
        if (this.listObj[objKeyArr[i]].uid === uid) {
          delete this.listObj[objKeyArr[i]]
          return
        }
      }
    },
    beforeUpload(file) {
      const _self = this
      const _URL = window.URL || window.webkitURL
      const fileName = file.uid
      this.listObj[fileName] = {}
      return new Promise((resolve, reject) => {
        const img = new Image()
        img.src = _URL.createObjectURL(file)
        img.onload = function() {
          _self.listObj[fileName] = { hasSuccess: false, uid: file.uid, width: this.width, height: this.height }
        }
        resolve(true)
      })
    }
  }
}
</script>

<style lang="scss" scoped>
.editor-slide-upload {
  margin-bottom: 20px;
  /deep/ .el-upload--picture-card {
    width: 100%;
  }
}
</style>

Tinymce/plugins.js中的内容：

// Any plugins you want to use has to be imported
// Detail plugins list see https://www.tinymce.com/docs/plugins/
// Custom builds see https://www.tinymce.com/download/custom-builds/

const plugins = ['advlist anchor autolink autosave code codesample colorpicker colorpicker contextmenu directionality emoticons fullscreen hr image imagetools insertdatetime link lists media nonbreaking noneditable pagebreak paste preview print save searchreplace spellchecker tabfocus table template textcolor textpattern visualblocks visualchars wordcount']

export default plugins

Tinymce/toolbar.js的内容：

// Here is a list of the toolbar
// Detail list see https://www.tinymce.com/docs/advanced/editor-control-identifiers/#toolbarcontrols

const toolbar = ['searchreplace bold fontsizeselect italic underline strikethrough alignleft aligncenter alignright outdent indent  blockquote undo redo removeformat subscript superscript code codesample', 'hr bullist numlist link image charmap preview anchor pagebreak insertdatetime media table emoticons forecolor backcolor fullscreen']

export default toolbar

在看看Tinymce/index.vue中的内容：

<template>
  <div :class="{fullscreen:fullscreen}" class="tinymce-container" :style="{width:containerWidth}">
    <textarea :id="tinymceId" class="tinymce-textarea" />
    <!-- <div class="editor-custom-btn-container">
      <editorImage color="#1890ff" class="editor-upload-btn" @successCBK="imageSuccessCBK" />
    </div> -->
  </div>
</template>

<style scoped>
.tinymce-container {
  position: relative;
  line-height: normal;
}
.tinymce-container>>>.mce-fullscreen {
  z-index: 10000;
}
.tinymce-textarea {
  visibility: hidden;
  z-index: -1;
}
.editor-custom-btn-container {
  position: absolute;
  right: 4px;
  top: 4px;
  /*z-index: 2005;*/
}
.fullscreen .editor-custom-btn-container {
  z-index: 10000;
  position: fixed;
}
.editor-upload-btn {
  display: inline-block;
}
</style>

最后，在需要引入的页面内引入；

<template>
  <div >
    <tinymce v-model="content" :height="300" />

  </div>

</template>

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

export default {
  components:{
    Tinymce
  }
</script>

效果：
