Office.js 读取工作表属性

使用 Office.js 读取（和设置）文档属性的功能最近作为 API 要求集 ExcelApi 1.7 的一部分提供。此要求集目前处于测试阶段，因此要使用此 API 功能，请执行以下操作：

• 您需要参考 beta 版 CDN：https://appsforoffice.microsoft.com/lib/beta/hosted/office.js

• 如果您使用的是 TypeScript，则需要引用 beta d.ts 文件：https://appsforoffice.microsoft.com/lib/beta/hosted/office.d.ts

• 必须使用足够新的 Excel 版本（例如，Office 预览体验成员快速）。如果您的构建时间不够新，并且尝试使用读取文档属性 API，则会引发错误。ApiNotFound

以下代码片段显示了 show to read 文档属性（使用 JavaScript）：

Excel.run(function (context) {
    var docProperties = context.workbook.properties;

    // Load a combination of read-only 
    // and writeable document properties.
    docProperties.load("author, lastAuthor, revisionNumber, title, subject, keywords, comments, category, manager, company, creationDate");

    return context.sync()
        .then(function () {

            // Write the document properties to the console.
            console.log("Author: " + docProperties.author);
            console.log("Last author : " + docProperties.lastAuthor);
            console.log("Revision number: " + docProperties.revisionNumber);
            console.log("Title: " + docProperties.title);
            console.log("Subject: " + docProperties.subject);
            console.log("Keywords: " + docProperties.keywords);
            console.log("Comments: " + docProperties.comments);
            console.log("Category: " + docProperties.category);
            console.log("Manager: " + docProperties.manager);
            console.log("Company: " + docProperties.company);
            console.log("Workbook creation date: " + docProperties.creationDate.toDateString());
        });
}).catch(errorHandlerFunction);

这是相同的代码片段，但在 TypeScript 中：

Excel.run(async (context) => {
    let docProperties = context.workbook.properties;

    // Load a combination of read-only 
    // and writeable document properties.
    docProperties.load("author, lastAuthor, revisionNumber, title, subject, keywords, comments, category, manager, company, creationDate");

    await context.sync();

    // Write the document properties to the console.
    console.log("Author: " + docProperties.author);
    console.log("Last author : " + docProperties.lastAuthor);
    console.log("Revision number: " + docProperties.revisionNumber);
    console.log("Title: " + docProperties.title);
    console.log("Subject: " + docProperties.subject);
    console.log("Keywords: " + docProperties.keywords);
    console.log("Comments: " + docProperties.comments);
    console.log("Category: " + docProperties.category);
    console.log("Manager: " + docProperties.manager);
    console.log("Company: " + docProperties.company);
    console.log("Workbook creation date: " + docProperties.creationDate.toDateString());
});
