【Vue】集成富文本编辑器

这文章使用的是wangeditor插件，官网地址：wangEditor，这个比较简单

安装

npm i wangeditor --save

使用 

<div id="editor"></div>import E from "wangeditor"const editor = new E("#editor")
editor.create()//或者
export default {
data() {return {editor: null}
}
this.editor = new E(`#editor`)//设置参数
this.editor.create() //创建

报错：

原因是在打开表单的时候元素还没创建好，所以找不到

解决方法：

使用NextTick：在下次 DOM 更新循环结束之后执行延迟回调。在修改数据之后立即使用这个方法，获取更新后的 DOM。

this.$nextTick(() => {this.editor = new E(`#editor`)//设置参数this.editor.create() //创建})

 

销毁编辑器

关闭时销毁，不然下次打开内容还在编辑器中

//在dialog销毁时调用
beforeDestroy() {
this.editor.destroy ()
this.editor = null
}

// 获取编辑器内容
this.editor.txt.html()

配置图片上传

 配置图片上传接口

 @PostMapping("/editor/upload")public Dict editorUpload(MultipartFile file) throws IOException {String originaFilename = file.getOriginalFilename();//文件原始名 a.jpgString mainname = FileUtil.mainName(originaFilename);//aString extname = FileUtil.extName(originaFilename);//jpgFile parentFile = new File(ROOT_PATH);if (!FileUtil.exist(ROOT_PATH)) {//若当前父级目录不存在就创建一个FileUtil.mkdir(ROOT_PATH);}if (FileUtil.exist(ROOT_PATH + File.separator + originaFilename)) {//若当前上传的文件名已存在，则重命名originaFilename = System.currentTimeMillis() + "_" + mainname + "." + extname;//124234_a.jpg}File saveFile = new File(ROOT_PATH + File.separator + originaFilename);file.transferTo(saveFile);//存储到本地String url = "http://localhost:8080/file/download/" + originaFilename;Dict dict=Dict.create().set("errno",0).set("data", CollUtil.newArrayList(Dict.create().set("url",url)));//返回return dict;}

前端使用接口：

this.editor.config.uploadImgServer = this.$baseUrl + '/file/editor/upload'
this.editor.config.uploadFileName = 'file'
this.editor.config.uploadImgHeaders = {token: this.user.token
}

server 接口返回格式，重要!!!

{
"errno": 0,
"data":[{url:"图片地址"}]
}

视频上传

this.editor.config.uploadVideoServer = this.$baseUrl + '/file/editor/upload'this.editor.config.uploadVideoName = 'file'this.editor.config.uploadVideoHeaders = {token: this.user.token}

写到这里报错了，最后发现视频的格式和图片格式要求不一样，视频格式：

 所以需要改一下后端接口，判断是视频还是图片，最后完整代码：

接口：

@PostMapping("/editor/upload")public Dict editorUpload(@RequestParam MultipartFile file, @RequestParam String type) throws IOException {String originaFilename = file.getOriginalFilename();String mainname = FileUtil.mainName(originaFilename);String extname = FileUtil.extName(originaFilename);if (!FileUtil.exist(ROOT_PATH)) {FileUtil.mkdir(ROOT_PATH);}if (FileUtil.exist(ROOT_PATH + File.separator + originaFilename)) {//若当前上传的文件名已存在，则重命名originaFilename = System.currentTimeMillis() + "_" + mainname + "." + extname;//124234_a.jpg}File saveFile = new File(ROOT_PATH + File.separator + originaFilename);file.transferTo(saveFile);//存储到本地String url = "http://localhost:8080/file/download/" + originaFilename;Dict dict = Dict.create().set("errno", 0);if ("img".equals(type)) {dict = Dict.create().set("errno", 0).set("data", CollUtil.newArrayList(Dict.create().set("url", url)));} else if ("video".equals(type)) {dict = Dict.create().set("errno", 0).set("data", Dict.create().set("url", url));}//返回return dict;}

前端：

//编辑显示
this.$nextTick(() => {this.editor = new E(`#editor`)//设置参数this.editor.config.uploadImgServer = this.$baseUrl + '/file/editor/upload'this.editor.config.uploadFileName = 'file'this.editor.config.uploadImgHeaders = {token: this.user.token}this.editor.config.uploadImgParams = {type: 'img'}this.editor.config.uploadVideoServer = this.$baseUrl + '/file/editor/upload'this.editor.config.uploadVideoName = 'file'this.editor.config.uploadVideoHeaders = {token: this.user.token}this.editor.config.uploadVideoParams = {type: 'video'}this.editor.create() //创建this.editor.txt.html(row.content)})
