NPM version Build Status

Demo

Live Demo

特性

  • 懒加载 umeditor.min.js 文件。
  • 支持umeditor事件监听与移除
  • 支持语言切换
  • 支持umeditor实例对象直接访问。

使用

1、安装

npm install ngx-umeditor --save

UMeditorModule 模块导入到你项目中。

import { UMeditorModule } from 'ngx-umeditor';

@NgModule({
    imports: [BrowserModule, UMeditorModule.forRoot() ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

2、使用

<umeditor [(ngModel)]="full_source" 
         [config]="{...}"
         [path]="'./assets/umeditor/'"
         [loadingTip]="'加载中……'"
         (onReady)=""
         (onDestroy)=""></umeditor>
名称 类型 默认值 描述
config Object 前端配置项说明,见官网
path string ./assets/umeditor/ umeditor代码根目录路径,以 / 结尾。
loadingTip string 加载中... 初始化提示文本。
onReady Function 编辑器准备就绪后会触发该事件
onDestroy Function 编辑器组件销毁后会触发该事件

3、关于懒加载

懒加载在未到 wdinow.UM 时会启动,如果你在 index.html 已经使用 <script src="umeditor.js"></script> 加载过,懒加载流程将会失效。

加载语言注意点

懒加载会自动识别并引用,否则,需要自行在 <head> 加入语言版本脚本。

访问umeditor实例对象

首先,需要给组件定义一下模板变量:

<umeditor [(ngModel)]="full_source" #full></umeditor>

使用 @ViewChild 访问组件,并使用 this.full.Instance 访问umeditor实例对象。

export class DemoComponent {
    @ViewChild('full') full: UeditorComponent;
    constructor(private el: ElementRef) {}

    getAllHtml() {
        // 通过 `this.full.Instance` 访问umeditor实例对象
        alert(this.full.Instance.getAllHtml())
    }
}

事件

虽说上节也可以直接注册umeditor事件,但当组件被销毁时可能会引发内存泄露。所以不建议直接在umeditor实例中这么做。组件本身提供 addListenerremoveListener 来帮你处理。

// 事件监听
this.full.addListener('focus', () => {
    this.focus = `fire focus in ${new Date().getTime()}`;
});
// 事件移除
this.full.removeListener('focus');

表单非空校验

组件加入 required 当编辑器为空时会处于 ng-invalid 状态,具体体验见Live Demo

组件接口

interface UMeditorComponent {
    /**
     * 获取UM实例
     * 
     * @readonly
     */
    get Instance(): any;

        /**
     * 设置编辑器语言
     * 
     * @param {('zh-cn' | 'en')} lang 
     */
    setLanguage(lang: 'zh-cn' | 'en') {}

    /**
     * 添加编辑器事件
     */
    addListener(eventName: 'destroy' | 'reset' | 'focus' | 'langReady' | 'beforeExecCommand' | 'afterExecCommand' | 'firstBeforeExecCommand' | 'beforeGetContent' | 'afterGetContent' | 'getAllHtml' | 'beforeSetContent' | 'afterSetContent' | 'selectionchange' | 'beforeSelectionChange' | 'afterSelectionChange', 
                fn: Function): void {}

    /**
     * 移除编辑器事件
     * 
     * @param {('destroy' | 'reset' | 'focus' | 'langReady' | 'beforeExecCommand' | 'afterExecCommand' | 'firstBeforeExecCommand' | 'beforeGetContent' | 'afterGetContent' | 'getAllHtml' | 'beforeSetContent' | 'afterSetContent' | 'selectionchange' | 'beforeSelectionChange' | 'afterSelectionChange')} eventName 
     */
    removeListener(eventName: 'destroy' | 'reset' | 'focus' | 'langReady' | 'beforeExecCommand' | 'afterExecCommand' | 'firstBeforeExecCommand' | 'beforeGetContent' | 'afterGetContent' | 'getAllHtml' | 'beforeSetContent' | 'afterSetContent' | 'selectionchange' | 'beforeSelectionChange' | 'afterSelectionChange'): void {}
}

Troubleshooting

Please follow this guidelines when reporting bugs and feature requests:

  1. Use GitHub Issues board to report bugs and feature requests (not our email address)
  2. Please always write steps to reproduce the error. That way we can focus on fixing the bug, not scratching our heads trying to reproduce it.

Thanks for understanding!
