富文本编辑器Quill(二)上传图片与视频
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
image與video在Quill formats中屬于Embeds,要在富文本中插入圖片或者視頻需要使用insertEmbed api。
insertEmbed
insertEmbed(index: Number, type: String, value: any, source: String = 'api'): Delta插入圖片需要位置,內(nèi)容類型以及圖片的url:
quill.insertEmbed(10, 'image', 'https://quilljs.com/images/cloud.png')獲取位置:
const range = quill.getSelection();上傳圖片
首先toolbar中添加image,還需要一個(gè)隱藏input元素用來上傳圖片:
<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>為image添加handler,點(diǎn)擊時(shí)上傳圖片:
this.quill.getModule("toolbar").addHandler("image", this.uploadImageHandler)handler:
uploadImageHandler () {const input = document.querySelector('#uploadImg')input.value = ''input.click()},為input元素添加onchange事件,獲取上傳圖片,上傳服務(wù)器,獲取圖片地址,將地址插入到編輯器中:
async uploadImage (event) {const form = new FormData()form.append('upload_file', event.target.files[0])const url = await $.ajax(...) #上傳圖片 獲取地址const addImageRange = this.quill.getSelection()const newRange = 0 + (addImageRange !== null ? addImageRange.index : 0)this.quill.insertEmbed(newRange, 'image', url)this.quill.setSelection(1 + newRange)}全部代碼:
<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 = nulldelete this.quill},methods: {initQuill () {const quill = new Quill('#editor', {theme: 'snow',modules: {toolbar: '#toolbar'}})this.quill = quillthis.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>上傳視頻做些少許修改就可以了:
<input id="uploadVideo" type="file" style="display:none" accept="video/*" @change="uploadVideo"> this.quill.getModule("toolbar").addHandler("video", this.uploadVideoHandler) uploadVideoHandler () {...} async uploadVideo (event) {...}定制Video
默認(rèn)的video上傳會(huì)存在一個(gè)問題,上傳后video是放在iframe中的,一般情況下是沒有問題的,但在小程序中使用h5頁面時(shí),iframe中的域名需要添加到小程序業(yè)務(wù)域名中,否則會(huì)禁止訪問。
更好的解決方法是簡單的添加一個(gè)video元素,而不是iframe,我們需要定制一個(gè)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')};} }注冊(cè):
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>
