加上跳转：.onClick(() => { call.makeCall(this.bookInfo.phone, err => { Logger.debug(`makeCall callback: err->${JSON.stringify(err)}`); });})

开头加上@State bookDetails: string = (router.getParams() as Record)['bookDetails'];@State bookInfo: BookModel = {}aboutToAppear() { this.bookInfo = JSON.parse(this.bookDetails);}

还需导入：import router from '@ohos.router';import common from '@ohos.app.ability.common';import util from '@ohos.util';import Logger from '../common/Logger';import { BookModel } from '../model/BookModel';import BookTableTools from '../rdb/BookTableTools';import { BookData } from '../rdb/BookData';

在开头加上即可@State libraryName: string = (router.getParams() as Record)['libraryName'];@State bookModelList: Array = [];@State bookData: BookData = {}@State bookTools: BookTableTools = new BookTableTools();
