Question

在我的Excel加载项中，我想按顺序对文档执行多次编辑。我正在使用承诺链来实现这个目标。

不幸的是，我从某些编辑中获得了GeneralException: An internal error has occurred.。

以下示例执行250次编辑，每次运行时我获得20到30个GeneralExceptions。（使用Office 2016，在Office上，它更糟糕）

示例：

var promise;

Office.initialize = function (reason) {

  // add awesome addin initialize code here

  promise = new OfficeExtension.Promise(function (resolve, reject) { resolve(null); });

  for (var i = 0; i < 200; i++) {
    insertData("Data" + i);
  }
}

function insertData(data) {
  if (Office.context.requirements.isSetSupported("ExcelApi", "1.0")) {
    //insert the data into the spreadsheet
    promise = promise.then(function () {
      Excel.run(function (ctx) {
        var sheet = ctx.workbook.worksheets.getActiveWorksheet();
        var range = ctx.workbook.getSelectedRange();
        range.getCell(0, 0).values = data;
        range.getCell(1, 0).select();
        return ctx.sync()
      }).catch(function (error) {
        addLogEntry(error.message);
      });
    });
  }
  else if (Office.context.requirements.isSetSupported("WordApi", "1.0")) {
    promise = promise.then(function () {
      Word.run(function (ctx) {
        var body = ctx.document.body;

        var selectedRange = ctx.document.getSelection();
        selectedRange.insertText(data + "\n", 'End');
        selectedRange.select('End');

        return ctx.sync();
      }).catch(function (error) {
        addLogEntry(error.message);
      });
    });
  }
}

function addLogEntry(message) {
  // log message here
}

我做错了什么？

这里是错误的堆栈跟踪：

我找到了一个解决方案，但它不是很优雅且非常慢（特别是在办公室在线）

也许有人能想出更好的东西？ ;）

这里是固定的insertData函数：

var isSending = false;

function insertData(data) {
  if (!isSending) {
    isSending = true;
    if (Office.context.requirements.isSetSupported("ExcelApi", "1.0")) {
      //insert the data into the spreadsheet
      //promise = promise.then(function () {
        Excel.run(function (ctx) {
          var sheet = ctx.workbook.worksheets.getActiveWorksheet();
          var range = ctx.workbook.getSelectedRange();

          range.getCell(0, 0).values = data;
          range.getCell(1, 0).select();

          return ctx.sync()
        }).then(function () {
          isSending = false;
          if (queue.length > 0) {
            insertData(queue.splice(0, 1)[0]);
          }
        }).catch(function (error) {
          addLogEntry(error.message);
        });
      //});
    }
    else if (Office.context.requirements.isSetSupported("WordApi", "1.0")) {
      //promise = promise.then(function () {
        Word.run(function (ctx) {
          var body = ctx.document.body;
          var selectedRange = ctx.document.getSelection();

          selectedRange.insertText(data + "\n", 'End');
          selectedRange.select('End');

          return ctx.sync();
        }).then(function () {
          isSending = false;
          if (queue.length > 0) {
            insertData(queue[0]);
            queue = queue.splice(0, 1);
          }
        }).catch(function (error) {
          addLogEntry(error.message);
        });
      //});
    }
  }
  else {
    queue.push(data);
  }
}
