Angular5整合富文本编辑器TinyMCE的方法(汉化+上传)

1. TinyMCE简介

TinyMCE是一个轻量级的富文本编辑器，相对于CK编辑器更加精简，但必须满足绝大部分场景的需要。

2.安装和配置TinyMCE

2.1安装TinyMCE

npm install-保存tinymce

2.2设置tinymce局部访问（.angular-cli.json）

"scripts": [
  "../node_modules/_tinymce@4.7.4/tinymce.js",
  "../node_modules/_tinymce@4.7.4/themes/modern/theme.js",
  "../node_modules/_tinymce@4.7.4/plugins/link/plugin.js",
  "../node_modules/_tinymce@4.7.4/plugins/paste/plugin.js",
  "../node_modules/_tinymce@4.7.4/plugins/table/plugin.js"
 ],

2.3定义变量

在项目中的typing.d.ts中

声明tinymce

变量，不然会提示发现tinymce

声明var tinymce：任何；

2.4拷贝皮肤文件到资产目录下

Linux和MacOS

cp -r node_modules / tinymce / skins src / assets / skins

2.5安装中文支持

中文语言包可以从这个地址下载：

https：//www.tinymce.com/downl ...

下载下来的压缩文件中会有一个langs目录，里面有zh_CN.js，把这个目录复制到src / assets目录下，然后在上下中添加引用（.angular-cli.json）：

“ scripts”：[

"../node_modules/_tinymce@4.7.4/tinymce.js",
 "../node_modules/_tinymce@4.7.4/themes/modern/theme.js",
 "../node_modules/_tinymce@4.7.4/plugins/link/plugin.js",
 "../node_modules/_tinymce@4.7.4/plugins/paste/plugin.js",
 "../node_modules/_tinymce@4.7.4/plugins/table/plugin.js",
 "../src/assets/langs/zh_CN.js"复制代码
]，

3.创建TinyMCE组件

ng gc myeditor

import {
 Component,
 AfterViewInit,
 EventEmitter,
 OnDestroy,
 Input,
 Output
} from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';

@Component({
 selector: 'tiny-editor',
 templateUrl: './tiny-editor.component.html',
 styleUrls: ['./tiny-editor.component.css']
})
export class TinyEditorComponent implements AfterViewInit, OnDestroy {
 @Input() elementId: String;
 @Output() onEditorContentChange = new EventEmitter();

 editor;

 constructor() { }

 ngAfterViewInit() {
  let self = this;
  tinymce.init({
   selector: '#' + this.elementId,
   height: 600,
   plugins: ['link', 'table', 'image'],
   skin_url: 'assets/skins/lightgray',
   setup: editor => {
    this.editor = editor;
    editor.on('keyup change', () => {
     const content = editor.getContent();
     this.onEditorContentChange.emit(content);
    });
   }
  });
 }

 ngOnDestroy() {
  tinymce.remove(this.editor);
 }

}

// tiny-editor.component.html
<textarea id="{{elementId}}">
</textarea>

4.使用自定义TinyMCE组件

<tiny-editor [elementId]="'defined-tinymce-editor'">
</tiny-editor>

5.增加图片上传功能

import {
 Component,
 AfterViewInit,
 EventEmitter,
 OnDestroy,
 Input,
 Output
} from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';

@Component({
 selector: 'tiny-editor',
 templateUrl: './tiny-editor.component.html',
 styleUrls: ['./tiny-editor.component.css']
})
export class TinyEditorComponent implements AfterViewInit, OnDestroy {
 @Input() elementId: String;
 @Output() onEditorContentChange = new EventEmitter();
 editor;
 constructor(private http: HttpClient) { }
 ngAfterViewInit() {
  let self = this;
  tinymce.init({
   selector: '#' + this.elementId,
   height: 600,
   plugins: ['link', 'table', 'image'],
   skin_url: 'assets/skins/lightgray',
   setup: editor => {
    this.editor = editor;
    editor.on('keyup change', () => {
     const content = editor.getContent();
     this.onEditorContentChange.emit(content);
    });
   },
   // 图片上传功能
   images_upload_handler: function(blobInfo, success, failure) {
    var formData;
    formData = new FormData();
    console.log(blobInfo);
    formData.append("file", blobInfo.blob(), blobInfo.filename());
    console.log(formData);
    self.uploadFile('http://www.seenode.com/index/player/upload', formData).subscribe( response => {
     let url = response['data']['imagePath'];
     success(url);
    });
   }
  });
 }
 // 上传图片
 private uploadFile(url: string, formData: any) {
  var self = this;
  var headers = new HttpHeaders();
  headers.set("Accept", "application/json");
  return self.http.post(url, formData, { headers: headers });
 }

 ngOnDestroy() {
  tinymce.remove(this.editor);
 }
}

6.获取和设置编辑器内容

<tiny-editor 
 [elementId]="'defined-tinymce-editor'"
 (onEditorContentChange)="keyupHandler($event)"></tiny-editor>复制代码
// 监听onEditorKeyup事件
private keyupHandler(event) {
 console.log('编辑器的内容：', event);
}
