基于Stencil组件的SharePoint新闻文本搜索过滤器部分用户报错问题

• 业务背景：在SharePoint站点部署了自研新闻过滤组件，支持用户输入匹配新闻标题、描述内容的关键词完成新闻检索
• 异常表现：仅2名特定用户通过文本输入触发搜索时会抛出运行错误，该组件功能对其余所有用户均可正常运行
• 参考资料：配套对应报错截图用于问题定位，组件实现代码如下

组件核心代码实现 #

组件业务逻辑（Stencil框架） #

import {
  Component,
  Host,
  h,
  Prop,
  Event,
  EventEmitter,
  Element,
} from "@stencil/core";
import { uniqueCategorias } from "./../../utils/utils";

export interface SearchData {
  dtInicio?: string;
  dtFim?: string;
  categoria?: string;
  texto?: string;
  isFilter?: boolean;
}

@Component({
  tag: "snt-noticias-cards-filtro",
  styleUrl: "noticias-cards-filtro.scss",
  shadow: true,
})
export class SntNoticiasCardsFiltro {
  @Element() private element: HTMLElement
  // 获取分类下拉框DOM实例
  get ddlCategoria(): any {
    return this.element.shadowRoot.querySelector("#ddlCategoria") as any;
  }
  // 获取分类下拉框全量选项
  get allddlCategoria(): NodeListOf<HTMLElement> {
    return this.element.shadowRoot.querySelectorAll(
      "ul > snt-option"
    ) as NodeListOf<HTMLElement>;
  }
  // 获取开始日期选择器实例
  get dtInicio(): any {
    return this.element.shadowRoot.querySelector("#dtInicio") as any;
  }
  // 获取结束日期选择器实例
  get dtFim(): any {
    return this.element.shadowRoot.querySelector("#dtfim") as any;
  }
  // 获取搜索文本输入框实例
  get txtPesquisar(): HTMLInputElement {
    return this.element.shadowRoot.querySelector(
      "#txtPesquisar"
    ) as HTMLInputElement;
  }

  // 向外抛出搜索事件
  @Event({ eventName: "search", bubbles: false }) search: EventEmitter<SearchData>;

  // 组件公共属性
  @Prop() disable: boolean = true;
  @Prop() categorias: any[];
  @Prop() itenSelect: string;

  categoriasFilter: any[] = [];

  // 组件加载完成后初始化去重分类列表
  async componentDidLoad() {
    this.categoriasFilter = uniqueCategorias(this.categorias);
  }

  // 汇总筛选条件并触发搜索事件
  async searchHandler(event?: CustomEvent) {
    this.search.emit({
      categoria: this.itenSelect,
      texto: this.txtPesquisar.value,
      dtInicio: await this.dtInicio.getDate(),
      dtFim: await this.dtFim.getDate(),
    });
    event && event.stopPropagation();
  }

  // 分类下拉值变更回调
  changeDllCategoria({ detail }) {
    this.itenSelect = detail;
  }

  // 清空所有筛选条件并重新触发搜索
  clear() {
    this.txtPesquisar.value = null;
    this.dtInicio.clearDate();
    this.dtFim.clearDate();
    this.itenSelect = "";
    this.ddlCategoria.setValue("");
    this.searchHandler();
  }
}
