要使用文档属性，请按照以下示例操作：
您可以直接修改文档的属性和应用程序属性。支持的属性如下：
您可以使用customDocPropsManager来操作文档的自定义属性。例如：
import { sheetJSON } from './utils.js';
var spreadNS = GC.Spread.Sheets;
window.onload = function () {
const spread = new spreadNS.Workbook(document.getElementById("ss"), { sheetCount: 1 });
document.getElementById('open').onclick = function () {
const file = document.querySelector('#selectedFile').files[0];
if (!file) { return; }
const fileType = getFileType(file);
if (fileType === 'xlsx') {
spread.import(file, () => {
initProductInformationSheet(spread);
});
}
};
document.getElementById('save').onclick = function () {
const sheetIndex = spread.getSheetIndex('Product Information');
if (typeof sheetIndex === 'number' && sheetIndex >= 0) {
spread.removeSheet(sheetIndex);
}
const fileName = 'export.xlsx';
const fileType = GC.Spread.Sheets.FileType.excel;
spread.export(function(blob) { saveAs(blob, fileName); }, function() {}, { fileType });
};
};
function initProductInformationSheet(spread) {
const docProps = spread.docProps;
spread.suspendPaint();
if (docProps) {
const newSheet = new GC.Spread.Sheets.Worksheet('Product Information');
newSheet.fromJSON(sheetJSON);
spread.addSheet(0, newSheet);
spread.setActiveSheetIndex(0);
const sheet = spread.getActiveSheet();
// set document properties
sheet.setValue(1, 1, docProps.coreDocProps && docProps.coreDocProps.title);
sheet.setValue(2, 1, docProps.coreDocProps && docProps.coreDocProps.subject);
sheet.setValue(3, 1, docProps.coreDocProps && docProps.coreDocProps.creator);
sheet.setValue(4, 1, docProps.coreDocProps && docProps.coreDocProps.keywords);
sheet.setValue(5, 1, docProps.coreDocProps && docProps.coreDocProps.description);
sheet.setValue(6, 1, docProps.coreDocProps && docProps.coreDocProps.category);
sheet.setValue(7, 1, docProps.coreDocProps && docProps.coreDocProps.contentStatus);
sheet.setValue(1, 3, docProps.appDocProps && docProps.appDocProps.manager);
sheet.setValue(2, 3, docProps.appDocProps && docProps.appDocProps.company);
sheet.setValue(3, 3, docProps.appDocProps && docProps.appDocProps.hyperlinkBase);
const customDocPropsManager = docProps.customDocPropsManager;
if (customDocPropsManager && customDocPropsManager.all()) {
customDocPropsManager.all().forEach((prop, index) => {
sheet.setValue(index + 1, 4, prop.name);
sheet.setValue(index + 1, 5, prop.value);
});
}
}
spread.resumePaint();
};
function getFileType (file) {
if (!file) { return; }
var fileName = file.name;
var extensionName = fileName.substring(fileName.lastIndexOf(".") + 1);
if (extensionName === 'xlsx' || extensionName === 'xlsm') {
return 'xlsx';
}
}
