我有一个加载项(使用officejs构建),可以下载,处理并将大数据数据放到Excel中。问题是当处理过长时,Excel会立即杀死加载项。我试图将所有工作委托给webworker,以使UI只执行信使的工作。问题是我不能在webworker中调用Office.initialize(我知道webworker有自己的范围等)。我的问题是 - 是否可以从网络工作者那里调用Excel,如果可以的话 - 如何正确地调用它们?
编辑:这是示例来源:
app.js
function createTableWorker() {
if (typeof(worker) == "undefined"){
console.log("creating new worker!");
worker = new Worker("test_worker.js");
}
worker.onmessage = function(event) {
console.log("From worker: " + event.data);
};
worker.postMessage("message");
}
worker.js
this.onmessage = function(e) {
console.log("Worker On Message!");
importScripts("https://appsforoffice.microsoft.com/lib/beta/hosted/office.debug.js");
doExcelWork();
}
function doExcelWork() {
Excel.run(function (context) {
debugger;
const currentWorksheet = context.workbook.worksheets.getActiveWorksheet();
const expensesTable = currentWorksheet.tables.add("A1:D1", true /*hasHeaders*/);
expensesTable.name = "ExpensesTable";
expensesTable.getHeaderRowRange().values =
[["Date", "Merchant", "Category", "Amount"]];
expensesTable.rows.add(null /*add at the end*/, [
["1/1/2017", "The Phone Company", "Communications", "120"],
["1/2/2017", "Northwind Electric Cars", "Transportation", "142.33"],
["1/5/2017", "Best For You Organics Company", "Groceries", "27.9"],
["1/10/2017", "Coho Vineyard", "Restaurant", "33"],
["1/11/2017", "Bellows College", "Education", "350.1"],
["1/15/2017", "Trey Research", "Other", "135"],
["1/15/2017", "Best For You Organics Company", "Groceries", "97.88"]
]);
expensesTable.columns.getItemAt(3).getRange().numberFormat = [['€#,##0.00']];
expensesTable.getRange().format.autofitColumns();
expensesTable.getRange().format.autofitRows();
return context.sync();
})
.catch(function (error) {
console.log("Error: " + error);
if (error instanceof OfficeExtension.Error) {
console.log("Debug info: " + JSON.stringify(error.debugInfo));
}
});
postMessage("Hello World Msg!");
}
通过关注https://docs.microsoft.com/en-us/office/dev/add-ins/tutorials/excel-tutorial并将Excel.run移动到网络工作者来创建示例。

您目前的设计无法奏效。 Excel.run()
必须位于已调用Office.initialize的上下文中。据我了解,如果输入大小足够小,你就有了一个可行的版本。您是否可以批量输入,以便使用它自己的Excel.run()
处理每个批次?然后通过调用Excel.run()
的新方法调用下一批处理。
