angular 5 和 quilljs [羊皮纸] 无法创建印迹

Question

我正在与 primeng editor and there is no any problem with editor itself, however I'm fighting two days in a row with extending standard block for custom tag, official documentation says for any additional feature to use quilljs api

合作

我检查了每个 api 和 github 上的问题，在我看来，我的方法是正确的，但我无法摆脱这个恼人的错误：

ERROR Error: [Parchment] Unable to create marker blot
at new ParchmentError (scripts.bundle.js:148)
at Object.create (scripts.bundle.js:178)
at BlockBlot.insertAt (scripts.bundle.js:7323)
at Block.insertAt (scripts.bundle.js:855)
at Scroll.ContainerBlot.insertAt (scripts.bundle.js:3404)
at ScrollBlot.insertAt (scripts.bundle.js:7060)
at Scroll.insertAt (scripts.bundle.js:4252)
at Editor.insertEmbed (scripts.bundle.js:2606)
at scripts.bundle.js:1379
at Quill.modify (scripts.bundle.js:1610)

我想要实现的是添加自定义标签，其中包含不可编辑的内容。这是我的代码：

...
import {Editor} from 'primeng/editor';

import * as Quill from 'quill';
import * as Parchment from 'parchment';
const Block = Quill.import('blots/block/embed');
class BlockEmbed extends Parchment.default.Embed {}
BlockEmbed.prototype = Block.prototype;

export class Variable extends BlockEmbed {

  static blotName = 'marker';
  static tagName = 'marker';

  static create(value: any) {
    console.log(value);
    const node = (super.create(value) as any);
    node.innerHTML = '<span contenteditable=false>' + value + '</span>';
    node.setAttribute('contenteditable', false);
    return node;
  }

}

Variable.blotName = 'marker';
Variable.tagName = 'marker';

Quill.register('formats/marker', Variable);

@Component({
  selector: 'manager',
  templateUrl: './manager.component.html',
  styleUrls: ['./manager.component.css']
})

export class ManagerComponent implements OnInit, AfterViewInit {

   private quill: any;
  @ViewChild(Editor) editorComponent: Editor;

  ngOnInit() {}

 // based on primeng github issue this how we can get references to quill 
  ngAfterViewInit() {
    this.quill = this.editorComponent.quill;
  }

 variableSelected(event) {
    // grubbing string variable from event 
    this.quill.insertEmbed(this.cursor.index || 0, 'marker', event.value);
  }

}

基于 quill github 中的这些主题，我的代码应该可以正常工作：

那么有人可以帮我找到我遗漏了什么或我的问题出在哪里吗？提前致谢。

Answer 1

我在使用 ngx-quill 时遇到了同样的问题。我认为问题与组件是在 webpack 隐藏的范围内声明的事实有关。因此我们无法访问正确的 Quill 实例来注册额外的组件。感谢 https://github.com/KillerCodeMonkey/ngx-quill 的 KillerCodeMonkey 的帮助，我得到了一个解决方案。删除任何其他 quill.js 导入（在 package.json 或 .angular-cli.json 中），这应该适用于 angular/core 5.2.0:

import * as Quill from 'quill'; 
import Parchment from "parchment";

console.log(Quill);
const QuillBlockEmbed = (Quill as any).import('blots/block/embed');

class BlockEmbed extends Parchment.Embed {};
BlockEmbed.prototype = QuillBlockEmbed.prototype;

class MyBlot extends BlockEmbed {
    static create(value) {
        let node: Element = super.create(value) as Element;
        if (typeof value === 'object') {
            node.classList.add("my-class");
        }
        return node;
    }
...
}

MyBlot.blotName = 'boltTwo';
MyBlot.tagName = 'img';

(Quill as any).register({ 'blots/myblot':MyBlot});

我很高兴用下一种方法解决我的问题

...
declare var Quill: any;
const BlockEmbed = Quill.import('blots/embed');

export class Variable extends BlockEmbed {

  static create(value: any) {
    const node = super.create(typeof value === 'object' ? value.text : value);
    node.innerText = typeof value === 'object' ? value.text : value;
    node.setAttribute('contenteditable', false);
    return node;
  }

  static value(node) {
    return {
      style: node.getAttribute('contenteditable'),
      text: node.innerText
    };
  }

}

Variable['blotName'] = 'marker';
Variable['className'] = 'marker';
Variable['tagName'] = 'span';

Quill.register('formats/marker', Variable);

export class ManagerComponent implements OnInit, AfterViewInit {

  private quill: any;

  @ViewChild('stepper') stepper;
  @ViewChild(Editor) editorComponent: Editor;

...

variableSelected(event) {
    this.quill.insertEmbed(this.cursor.index || 0, 'marker', event.value, 'user');
    this.quill.update('user'); 
  }

这种方式对我来说很好用：

import * as QuillNamespace from 'quill';
const Quill: any = QuillNamespace;

const BlockEmbed = Quill.import('blots/block/embed');
