Vue Quill Editor自定义图片/视频上传（Element UI + OSS）、字体、字体大小、段落等
近期项目中需要使用富文本编辑器，开始想到的富文本编辑器是百度的UEditor，UEditor功能齐全、插件多，但是图片只能上传到本地服务器，如果需要上传到其他服务器需要改动源码，而且是PHP、JSP、ASP、.Net版本，同时UEditor体积过大压缩包有3.3M（jsp版本），加载速度慢。实际项目中并不需要那么多的功能，只需要基础的操作：字体、字体大小、标题、段落、图片上传、视频上传、居中对

近期项目中需要使用富文本编辑器，开始想到的富文本编辑器是百度的UEditor，UEditor功能齐全、插件多，但是图片只能上传到本地服务器，如果需要上传到其他服务器需要改动源码，而且是PHP、JSP、ASP、.Net版本，同时UEditor体积过大压缩包有3.3M（jsp版本），加载速度慢。实际项目中并不需要那么多的功能，只需要基础的操作：字体、字体大小、标题、段落、图片上传、视频上传、居中对齐等；所以我们只需要一个轻量级的富文本编辑器就行，推荐使用Quill和TinyMCE，Quill和TinyMCE都是轻量级，插件多，功能强，编辑能力优秀，界面好看。选择Quill的原因是它所有能看到的，不能看到的功能统统都是一个一个独立的模块，全部都是可以替换的，可以自定义编辑。
站在巨人vue-quill-editor的肩膀上进行Quill editor的自定义图片/视频上传（Element UI + OSS）、字体、字体大小、标题、段落等封装。先看效果再来编码：
<template>
<div>
<quill-editor ref="myTextEditor"

@focus="onEditorFocus($event)"
@ready="onEditorReady($event)"
@change="onEditorChange($event)"

<div id="toolbar" slot="toolbar">

1、自定义字体、字体大小、段落
<div id="toolbar" slot="toolbar">
<select class="ql-header" title="段落格式">
<option selected>段落</option>
<option value="1">标题1</option>
<option value="2">标题2</option>
<option value="3">标题3</option>
<option value="4">标题4</option>
<option value="5">标题5</option>
<option value="6">标题6</option>
</select>
<select class="ql-size" title="字体大小">
<option value="10px">10px</option>
<option value="12px">12px</option>
<option value="14px">14px</option>
<option value="16px" selected>16px</option>
<option value="18px">18px</option>
<option value="20px">20px</option>
</select>
<select class="ql-font" title="字体">
<option value="SimSun" selected="selected"></option>
<option value="SimHei"></option>
<option value="Microsoft-YaHei"></option>
<option value="KaiTi"></option>
<option value="FangSong"></option>
<option value="Arial"></option>
<!-- <option value="Times-New-Roman"></option>
<option value="sans-serif"></option> -->
</select>
</div>
在Quill初始化之前进行注册：
// 自定义字体大小
let Size = Quill.import('attributors/style/size')
Size.whitelist = ['10px', '12px', '14px', '16px', '18px', '20px']
Quill.register(Size, true)
// 自定义字体类型
var fonts = ['SimSun', 'SimHei', 'Microsoft-YaHei', 'KaiTi', 'FangSong', 'Arial', 'Times-New-Roman', 'sans-serif']
var Font = Quill.import('formats/font')
Font.whitelist = fonts // 将字体加入到白名单
Quill.register(Font, true)
自定义字体、字体大小、段落需要在使用Quill编辑器之前引入quill.css，可以在App.vue或者main.js中引入。

/* .ql-font-Times-New-Roman {
font-family: "Times New Roman";

2、自定义图片和视频上传（Element UI + OSS）
<div id="toolbar" slot="toolbar">
<button id="custom-button" @click.prevent="fnOpenUploadImage" title="图片"><i class="iconfont icon-tupian"></i></button>
<button id="custom-button" @click.prevent="fnOpenUploadVideo" title="视频"><i class="iconfont icon-video2"></i></button>
</div>
自定义图片和视频上传使用的是Element UI + OSS上传组件，参考上一篇Vue Element UI + OSS上传文件，上传成功之后需要把图片或者视频插入内容区域，通过查看Quill文档，
insertEmbed(index: Number, type: String, value: any, source: String = 'api'): Delta
可以插入视频和图片：
/**
* [fnUploadSucess 提交上传文件函数]
* @author zoumiao
* @param {Array} uploadFileUrlList [上传文件返回的url]
* @return {null} [没有返回]
*/
fnUploadSucess (uploadFileUrlList) {
this.editor.focus()
for (let url of uploadFileUrlList) {
this.editor.insertEmbed(this.editor.getSelection().index, this.uploadType, url)
}
}
3、字数统计
Quill没有字节提供字数统计，API提供了getLength方法，但是如果输入空格，该方法也会计算为字符；通过editor-change事件来计算字符个数：
/**
* @description [onEditorChange 输入文本改变事件]
* @author zoumiao
* @param {Object} editor 返回的编辑对象{html, text, quill}
* @return {null} [没有返回]
*/
onEditorChange (editor) {
let html = editor.html
this.preContent = html
this.$emit('input', html)
this.contentLength = this._.trim(editor.text).length
},
4、图片可收缩
import { ImageDrop } from 'quill-image-drop-module'
import ImageResize from 'quill-image-resize-module'
Quill.register('modules/imageDrop', ImageDrop)
Quill.register('modules/imageResize', ImageResize)
Quill配置项中也要进行配置：
editorOption: {
modules: {
toolbar: '#toolbar',
history: {
delay: 1000,
maxStack: 50,
userOnly: false
},
imageDrop: true,
imageResize: {
displayStyles: {
backgroundColor: 'black',
border: 'none',
color: 'white'
},
modules: [ 'Resize', 'DisplaySize', 'Toolbar' ]
}
}
}
在开发环境中使用这两个插件没有什么问题，但是生成打包之后会报错，vue-quill-editor 的quill-image-resize-module 改变插入图片大小模块引入报错问题
