Question

我正在用Stencil编写我的第一个Web组件。
这是药丸成分，发布在这里：https://github.com/reservoir-dogs/rp-pills

组件代码：

import { Component, Prop, Watch, Event, EventEmitter } from '@stencil/core';

@Component({
  tag: 'rp-pills',
  styleUrl: 'rp-pills.scss',
  shadow: false
})
export class RpPills {

  @Prop() items: any[] = [];
  @Prop() displayProperty: string;
  @Prop({ mutable: true }) value: any;
  @Prop() class: string;
  @Prop() theme: string = 'default';
  @Prop() emptyMessage: string = 'No item';
  classes: string;

  @Event() valueChange: EventEmitter;

  onClick(item: any) {
    this.value = item;
    this.valueChange.emit(this.value);
  }

  @Watch('class')
  @Watch('theme')
  watchHandler() {
    this.classes = `nav nav-pills ${this.theme} ${this.class}`;
  }

  render() {
    if (this.items.length > 0)
      return (
        <ul class={this.classes}>
          {this.items.map((item) =>
            <li onClick={() => this.onClick(item)} class={this.value === item ? 'active' : ''} >
              <a>{item[this.displayProperty]}</a>
            </li>)}
        </ul>
      );
    else
      return (
        <ul class={this.classes}>
          <li class="empty">
            <a>{this.emptyMessage}</a>
          </li>
        </ul>
      );
  }
}

此测试工作正常：

it('should work with a list of items and selected item', async () => {
  const cmp = new RpPills();
  cmp.valueChange = {
    emit: () => { }
  };
  const spy = jest.spyOn(cmp.valueChange, 'emit');
  cmp.onClick({name:'Coucou'});
  expect(spy).toHaveBeenCalledWith({ name: 'Coucou' });
});

但是我的HTML示例和Ionic App中的集成无法正常工作，并返回以下消息：{“ isTrusted”：false}

      if (cmp.attributes.length > 0 && cmp.attributes[0].name == 'display-property') {
        cmp.value = { 'name': 'Coucou' };
        cmp.items = [cmp.value, { 'name': 'Comment ca va ?' }, { 'name': 'Au revoir' }];
        cmp.addEventListener('valueChange', (event) => { alert(JSON.stringify(event)); });
      }
    }
    setInterval(() => {

      var spans = document.querySelectorAll('span');

        if (cmps[i].value != undefined)
          spans[i].innerText = cmps[i].value.name;

Answer 1

2个错误

我试图这样做：

<rp-pills [items]="jeux" [(value)]="partie.jeu"></rp-pills>

我的模板组件的事件：

不兼容角度双向绑定
在具有我价值的地方包含属性“详细信息”

在Ionic App中使用

HTML代码

<rp-pills [items]="jeux" [value]="partie.jeu" (valueChange)="jeuChange($event.detail)"></rp-pills>

TypeScript代码

jeuChange(jeu: Jeu) {
  this.partie.jeu = jeu;
}

返回isTrusted false
