Angular5整合富文本编辑器TinyMCE（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，但必须知足绝大部分场景的须要。

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"
   ],复制代码

• 2.3定义变量

  在项目中的typing.d.ts中

  
  

  声明tinymce

  变量，否则会提示发现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

  中文语言包能够从这个地址下载：

  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，而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.建立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);
    }

}复制代码

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

4.使用自定义TinyMCE组件

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

5.增长图片上传功能

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);
    }

}
复制代码

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);
}复制代码
