介绍在Vue中使用quill-editor富文本插件，支持图片的放大缩小及拖动
效果图：
1、下载依赖
cnpm i vue-quill-editor --save
cnpm i quill-image-resize-module --save //图片操作
2、全局引入及注册main.js
import VueQuillEditor from 'vue-quill-editor';
import * as Quill from 'quill'; //引入编辑器
import resizeImage from 'quill-image-resize-module'; // 图片缩放组件。
Quill.register('modules/resizeImage ', resizeImage);
import 'quill/dist/quill.core.css';
import 'quill/dist/quill.snow.css';
import 'quill/dist/quill.bubble.css';
Vue.use(VueQuillEditor);
3、封装组件RichText
<template>
<div class="richBox" v-loading="spinning">
<quill-editor
v-model="content"
:options="editorOption"
ref="QuillEditor">
</quill-editor>
<input type="file"
ref="imgs"
accept="image/*" class="uploads" style="display: none;" @change="uploadImgs">
<input type="file"
ref="videos"
accept="video/*" class="upVideo" style="display: none;" @change="uploadVideo">
</div>
</template>
<script>
import {
uploads
} from "./upload.js" //uploads.js是封装的一个上传方法，可基于Promise进行封装
const toolbarOptions = [
['bold', 'italic', 'underline', 'strike'], // toggled buttons
['blockquote', 'code-block'],
[{'header': 1}, {'header': 2}], // custom button values
[{'list': 'ordered'}, {'list': 'bullet'}],
[{'script': 'sub'}, {'script': 'super'}], // superscript/subscript
[{'indent': '-1'}, {'indent': '+1'}], // outdent/indent
[{'direction': 'rtl'}], // text direction
[{'size': ['small', false, 'large', 'huge']}], // custom dropdown
[{'header': [1, 2, 3, 4, 5, 6, false]}],
[{'color': []}, {'background': []}], // dropdown with defaults from theme
[{'font': []}],
[{'align': []}],
['link', 'image', 'video'],
['clean'] // remove formatting button
]
export default{
props: {
values: { //用于回显
type: String,
default: ''
},
},
data(){
return{
spinning:false,
content: '',
editorOption: {
placeholder:"请输入",
modules: {
imageResize: { //图片放大缩小配置
displayStyles: {
backgroundColor: 'black',
border: 'none',
color: 'white'
},
modules: ['Resize', 'DisplaySize', 'Toolbar']
},
toolbar: {
container: toolbarOptions, // 工具栏
handlers: {
'image': function (value) {
if (value) {
document.querySelector('.uploads').click()
} else {
this.quill.format('image', false);
}
},
'video':function(value){
if (value) {
document.querySelector('.upVideo').click()
} else {
this.quill.format('video', false);
}
}
}
}
}
}
}
},
watch: { //监听回显的数据变化
values: {
handler(newVal, oldVal) {
this.content = newVal;
this.$refs.QuillEditor.quill.blur();
},
immediate: true
}
},
methods:{
getVal () { //返回内容
return this.content
},
setVal(data){ //赋值
this.content = data;
},
uploadImgs(e){ //上传图片
var file = this.$refs.imgs.files[0];
this.spinning = true
this.upFile(file,'image');
e.target.value = '';
},
uploadVideo(e){ //上传视频
var file = this.$refs.videos.files[0];
this.spinning = true
this.upFile(file,'video')
},
upFile(file,type){ //上传api
uploads(file).then(result => {
this.spinning = false
this.insertImg(result,type)
})
},
insertImg(url,type){ //插入图片
var quill = this.$refs.QuillEditor.quill;
let length = quill.getSelection().index;
quill.insertEmbed(length,type,url);
quill.setSelection(length+1);
}
}
}

4、使用
<richTxt ref="child" :values="form.content"/>
1、获取富文本内容：
let oldProcedure = this.$refs.child.getVal();
this.form.content= oldProcedure;5、万事俱备之后
运行项目可能会出现imports错误，这里提供了cli2和cli3两种解决方案
1. 在vue cli2中，处理方案如下:
找到webpack.base.conf文件，添加以下代码
const webpack = require('webpack');
module.exports = {
plugins: [
new webpack.ProvidePlugin({
'window.Quill': 'quill/dist/quill.js',
'Quill': 'quill/dist/quill.js'
})
],
}
2.在vue cli3中，处理方案如下：
在项目根目录找到vue.config.js文件，如果没有就创建此文件，添加以下代码
const webpack = require('webpack')
module.exports = {
chainWebpack: config => {
//富文本图片缩放
config.plugin('provide').use(webpack.ProvidePlugin, [{
'window.Quill': 'quill',
'Quill': 'quill/dist/quill.js'
}])
}
}
//注意 如果原文件有chainWebpack 不要重复添加，在原有chainWebpack里面的最后面添加上面代码
6、格式问题
v-html渲染格式问题：给v-html绑定的元素添加class="ql-editor"
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
