image与video在Quill formats中属于Embeds，要在富文本中插入图片或者视频需要使用insertEmbed api。
insertEmbed(index: Number, type: String, value: any, source: String = ‘api‘): Delta
插入图片需要位置，内容类型以及图片的url：
quill.insertEmbed(10, ‘image‘, ‘https://quilljs.com/images/cloud.png‘)
获取位置：
const range = quill.getSelection();
首先toolbar中添加image，还需要一个隐藏input元素用来上传图片：
<template>
<div>
<div id="toolbar">
<span class="ql-formats">
<button class="ql-image"></button>
<button class="ql-video"></button>
</span>
</div>
<div id="editor">
<p>Hello World!</p>
<p>Some initial <strong>bold</strong> text</p>
<p><br></p>
</div>
<input id="uploadImg" type="file" style="display:none" accept="image/png, image/jpeg, image/gif" @change="uploadImage">
</div>
</template>
为image添加handler，点击时上传图片：
this.quill.getModule("toolbar").addHandler("image", this.uploadImageHandler)
handler:
uploadImageHandler () {
const input = document.querySelector(‘#uploadImg‘)
input.value = ‘‘
input.click()
},
为input元素添加onchange事件，获取上传图片，上传服务器，获取图片地址，将地址插入到编辑器中：
async uploadImage (event) {
const form = new FormData()
form.append(‘upload_file‘, event.target.files[0])
const url = await $.ajax(...) #上传图片 获取地址
const addImageRange = this.quill.getSelection()
const newRange = 0 + (addImageRange !== null ? addImageRange.index : 0)
this.quill.insertEmbed(newRange, ‘image‘, url)
this.quill.setSelection(1 + newRange)
}
全部代码：
<template>
<div>
<div id="toolbar">
<span class="ql-formats">
<button class="ql-image"></button>
<button class="ql-video"></button>
</span>
</div>
<div id="editor">
<p>Hello World!</p>
<p>Some initial <strong>bold</strong> text</p>
<p><br></p>
</div>
<input id="uploadImg" type="file" style="display:none" accept="image/png, image/jpeg, image/gif" @change="uploadImage">
</div>
</template>
<script>
import Quill from ‘quill‘
export default {
name: "QuillEditor",
mounted () {
this.initQuill()
},
beforeDestroy () {
this.quill = null
delete this.quill
},
methods: {
initQuill () {
const quill = new Quill(‘#editor‘, {
theme: ‘snow‘,
modules: {
toolbar: ‘#toolbar‘
}
})
this.quill = quill
this.quill.getModule("toolbar").addHandler("image", this.uploadImageHandler)
},
uploadImageHandler () {
const input = document.querySelector(‘#uploadImg‘)
input.value = ‘‘
input.click()
},
async uploadImage (event) {
const form = new FormData()
form.append(‘upload_file‘, event.target.files[0])
const url = await $.ajax(...)
const addImageRange = this.quill.getSelection()
const newRange = 0 + (addImageRange !== null ? addImageRange.index : 0)
this.quill.insertEmbed(newRange, ‘image‘, url)
this.quill.setSelection(1 + newRange)
}
}
}
</script>
上传视频做些少许修改就可以了：
<input id="uploadVideo" type="file" style="display:none" accept="video/*" @change="uploadVideo">
this.quill.getModule("toolbar").addHandler("video", this.uploadVideoHandler)
uploadVideoHandler () {...}
async uploadVideo (event) {...}
默认的video上传会存在一个问题，上传后video是放在iframe中的，一般情况下是没有问题的，但在小程序中使用h5页面时，iframe中的域名需要添加到小程序业务域名中，否则会禁止访问。
更好的解决方法是简单的添加一个video元素，而不是iframe，我们需要定制一个Video Embed。
const BlockEmbed = Quill.import(‘blots/block/embed‘)
class VideoBlot extends BlockEmbed {
static create (value) {
let node = super.create()
node.setAttribute(‘src‘, value.url)
node.setAttribute(‘controls‘, value.controls)
node.setAttribute(‘width‘, value.width)
node.setAttribute(‘height‘, value.height)
node.setAttribute(‘webkit-playsinline‘, true)
node.setAttribute(‘playsinline‘, true)
node.setAttribute(‘x5-playsinline‘, true)
return node;
}
static value (node) {
return {
url: node.getAttribute(‘src‘),
controls: node.getAttribute(‘controls‘),
width: node.getAttribute(‘width‘),
height: node.getAttribute(‘height‘)
};
}
}
注册：
VideoBlot.blotName = ‘simpleVideo‘ VideoBlot.tagName = ‘video‘ Quill.register(VideoBlot)
插入Embed：
this.quill.insertEmbed(newRange, ‘simpleVideo‘, {
url,
controls: ‘controls‘,
width: ‘100%‘,
height: ‘100%‘
})
添加效果：
<video src="...mp4" controls="controls" width="100%" height="100%" webkit-playsinline="true" playsinline="true" x5-playsinline="true"></video>
