选择列时无法获取选定的范围值 - Excel Javascript

Question

我想知道我是否发现了另一个使用“整个列范围”的错误。我希望捕获选定的范围值，通常，当我选择范围时，我只需选择列标题“A”，它就会选择整个列。但是，在浪费时间测试之后，我意识到我的代码仅在我不选择列时才有效。

这是一个错误还是我的代码不正确？

有没有办法深入到“选定的值范围”？就像你可以如何做

getUsedRange(true)

一样，

true

是“仅使用带有值的范围”。

这有效：

console.log('A1 Select')
var ws = context.workbook.worksheets.getActiveWorksheet();
ws.getRange("A1").select()
await context.sync()

var range = context.workbook.getSelectedRange();
range.load(['values']);
await context.sync();

var firstSelectedCellValue = range.values[0][0];
console.log('firstSelectedCellValue:')
console.log(firstSelectedCellValue)
await context.sync();

这不起作用：

console.log('A Col Select')
ws.getRange("A:A").select()
await context.sync();

var range = context.workbook.getSelectedRange();
range.load(['values']);
await context.sync();

var firstSelectedCellValue = range.values[0][0];
console.log('firstSelectedCellValue:')
console.log(firstSelectedCellValue)
await context.sync();

这是输出：

好吧，我无法读取全范围值这一事实与

selectedRange

无关。我以前也曾沿着这条路走下去，基本上开发人员告诉他们，他们不在乎它是否按照您的预期工作，因为这将是一个缓慢的操作，并且需要调整用户代码，而不是 API .

您无法读取完整的列或行值。它将返回

null

。您需要检查

isEntireRow

或

isEntireColumn

，然后从范围中删除一行/列，然后进行检查。然后，您可以运行另一个操作来检查删除的单行/列（这比根据开发人员修复 API 更好..）

如果用户无论如何都选择了整个列/行，我计划深入到

usedRange

，所以下面是我最终得到的结果，我将其包装到一个函数中以获得“选定范围”。

var Load_Opts_Arr = ['rowCount','rowIndex', 'columnCount','columnIndex', 'values','isEntireColumn','isEntireRow']  

var rng = context.workbook.getSelectedRange();
rng.load(Load_Opts_Arr);
await context.sync();

if (rng.isEntireColumn == true || rng.isEntireRow == true) {
    var ws = context.workbook.worksheets.getActiveWorksheet();
    var Used_Rng_And_Props = ws.getUsedRange(true)
    Used_Rng_And_Props.load(['rowCount','rowIndex', 'columnCount','columnIndex'] );
    await context.sync();
}

if (rng.isEntireColumn == true) {
    var rng = ws.getRangeByIndexes(Used_Rng_And_Props.rowIndex, rng.columnIndex, Used_Rng_And_Props.rowCount, rng.columnCount)
    rng.load(Load_Opts_Arr);
    await context.sync();
}

if (rng.isEntireRow == true) {
    var rng = ws.getRangeByIndexes(rng.rowIndex, Used_Rng_And_Props.columnIndex, rng.rowCount, Used_Rng_And_Props.columnCount - rng.columnIndex)
    rng.load(Load_Opts_Arr);
    await context.sync();
}
