Question

我是电子表格脚本的新手。我正在根据另一张表格生成一份报告（新表格），我每天都会输入值。在Apps脚本中，我首先生成工作表然后遍历从该输入表检索到的数据范围。之后，我必须根据日期和类别合并值现在我的报告格式是行是类别而日期是列。因此，如果输入中有另一个具有相同日期和相同类别的值，则必须添加该值。

我的问题是如何检查报告中是否存在具有相同日期和类别的值，并且我不想使用循环，因为我已经在循环中，这样会使进程运行得非常慢。

Answer 1

我认为没有一些循环就可以做到这一点。由于此操作在服务器端执行而无需调用电子表格，因此即使使用非常大的数据集也只需要很短的时间。

如果您的脚本已经很慢，那很可能是因为脚本的其他部分效率低下/延迟。我有一个脚本，它复制了一个电子表格并重命名它，只有那些操作需要5到5之间。 8秒

举个例子：

  function test(){
  var ss = SpreadsheetApp.getActiveSheet().getDataRange().getValues();
  var value = "agdsdfgsdfg" // This value is in cell BD1000
  for(var i = 0; i < ss.length; i ++){
   if(ss[i].indexOf(value)>=0){
     var x = ss[i].indexOf(value) + 1;
     break;
   }
  }
  var y = i + 1
 // var x & y are the row, cell coordinates of value in the data range 
}

对数据集56列x 1000行执行的此操作在0.88秒内完成，搜索值位于范围的最后一个单元格中。

您的报告听起来有点像数据透视表，其中行中的类别，列中的日期以及作为数据字段的SUM（值）。要使用脚本报告重现此问题，您可以使用Object变量来映射密钥和＆＃34;值＆＃34; Object：

这可能不是您的确切用例（它假设您需要从可能大量的馈送器数据生成新报告，但它应该演示如何使用嵌套Object来简化/内化查找过程，包括测试未定义的值和强制执行矩形输出。

// Make an array of the data, to limit use of the slow spreadsheet interface.
var inputs = SpreadsheetApp.openById(<id>).getSheetByName(<dataSheetName>)
    .getDataRange().getValues();
// The first row is probably column headers from the input sheet, and
// doesn't likely contain useful data that you want in your report.
var headers = inputs.splice(0, 1);
var report = {};
for(var row = 0; row < inputs.length; ++row) {
    // Change these indexes (0, 1, 2) to the proper values.
    // Also do any necessary formatting / validation, etc. for "category" and "date".
    var category = inputs[row][0];
    var date = inputs[row][1];
    var value = inputs[row][2];
    // If this category doesn't exist, default construct its report object.
    // For each category, a nested object is used to store the date-value pair.
    if(!report[category]) {
        report[category] = {};
    }
    // Otherwise, if the date is not yet seen for the category, set
    // the value. If it is seen, increment the stored value by the new value.
    if(!report[category][date]) {
        report[category][date] = value;
    } else {
        // Treat this as numeric addition, not string concatenation.
        report[category][date] += value - 0;
    }
}
// To print your report, you need a header you can index against.
var outputHeader = [];
for(var category in report) {
    for(var date in category) {
        outputHeader.push(date);
    }
}
// Sort this header row. If the dates are strings that don't simply
// coerce to proper Date objects, you'll need to write your own sort() method.
// (You don't technically need to sort, but if you don't then the dates
// won't be "in order" when the report prints.)
outputHeader.sort();
// After sorting, add a row label for the header of sorted dates.
outputHeader.splice(0, 0, "Category / Date");

// Serialize the report object into an array[][];
var output = [outputHeader];
var totalColumns = outputHeader.length;
for(var category in report) {
    // Initialize each row with the row label in the 0 index position.
    var row = [category];
    for(var date in category) {
        var index = outputHeader.indexOf(date);
        row[index] = category[date];
    }
    // Unless you are guaranteed that every category has a value for every date
    // in the report, you need to ensure that the row has a value at each index.
    // (This is a good idea anyway, to ensure that you have a rectangular array.)
    var filled = Object.keys(row);
    // We can start at 1 since we know that every row starts with its category.
    for(var col = 1; col < totalColumns; ++col) {
        if(filled.indexOf(String(col)) < 0) {
            row[col] = "";
        }
    }
    output.push(row);
}
SpreadsheetApp.openById(<id>).getSheetByName(<reportSheetName>)
    .getRange(1, 1, output.length, output[0].length).setValues(output);
