javascript - 无法在 Google Apps 脚本表中使用类方法

Question

我有两个文件在 typescript 中输入，然后在 .gs 中编译为谷歌应用程序脚本。我有一类带有方法的辅助函数，当我调用此方法时: flatten_ 我收到错误

TypeError: Cannot find function flatten_ in object function Utils() {...}.

我尝试过:1. 使 flatten_ 成为静态方法2. 使 flatten_ 静态属性3. 将 flatten_ 声明为公共(public)函数类所有的人都没有决心。

后端.ts

import { Utils } from './utils/_';

function onOpen() {
    const ui = SpreadsheetApp.getUi();
    ui.createMenu('Tracker')
    .addItem('JUMP To Record', 'Jump')
    .addToUi();
}

function Jump() {
    const ui = SpreadsheetApp.getUi();
    const prompt = ui.prompt('Submit A Tracker ID');

    /** Once the user clicks ok */
    if(prompt.getSelectedButton() == ui.Button.OK) {
        /** If the tracker id length is less than 1 */
        if(prompt.getResponseText().length < 1) {
            Browser.msgBox('Submit A Valid Tracker Id');
        } else {
            /** Begin timer and find the tracker id record */
            console.time('Jump To Tracker Id Execution');
            const spreadsheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Client'); 
            const trackerRange = spreadsheet.getRange('1:1').getValues();
            const trackerColumn = trackerRange[0].indexOf('Tracker ID') + 1;
            const trackerIds = Utils.flatten_(spreadsheet.getRange(1, trackerColumn, spreadsheet.getLastRow(), 1).getValues());
            const recordIndex = trackerIds.indexOf(prompt.getResponseText());
            console.timeEnd('Submit A Valid Tracker Id');
            /** End timer and check record results */
            if(recordIndex == -1) {
                Browser.msgBox('Record ['+ prompt.getResponseText() + '] Could Not Be Found')
            } else {
                spreadsheet.setActiveRange(spreadsheet.getRange(recordIndex + 1, trackerColumn));
            }
        }
    }  
}

Answer 1

通过扩展我能够访问的类，我发现了这一点。

export class Utils {
    iArray: Array<any>
    constructor(_:Array<any>) {
        this.iArray = _;
    }
}

export class Flatten extends Utils {
    exe(): any {
        return [].concat.apply([], this.iArray);
    }
}

import { Flatten } from "./utils/_";

const trackerIds = new Flatten(spreadsheet.getRange(1, trackerColumn, spreadsheet.getLastRow(), 1).getValues()).exe();
