连接代码运行极其缓慢 google 脚本

Question

我的连接函数运行得非常慢，仅在 28 行数据上运行几乎需要 4 分钟，而且我还有其他代码需要运行，所以我在 Google 表格中达到了最大执行时间

如果我在 Excel 中运行类似的过程，这可能需要 15-30 秒

一切都在内存中，我看不到（以我对 javascript 的有限知识）为什么我的代码这么慢

谢谢

       if(v[row][col2-1].toString().indexOf(search_Term) > -1) {

          temp = temp + replace_Term + "|"

       }

     }

    //remove trailing pipe
     A[row][e] = temp.replace(/\|(?=\s*$)/, '')
       temp = ""

   }

 }

 A[0][0]= newHeader1
 A[0][1]= newHeader2

 s.getRange(1, v[0].length +1, v.length,A[0].length).setValues(A);

var end = new Date();
var executiontime = end - start;
Logger.log(executiontime);
};

//Helper function
function HTN(shtName,cheader){
var headers = 
SpreadsheetApp.getActiveSpreadsheet().getSheetByName(shtName).getDataRange().getValues().shift();

var colindex = headers.indexOf(cheader);
return colindex+1;
}

• 您希望降低脚本的流程成本。

如果我的理解是正确的，这个答案怎么样？请将此视为几种可能的答案之一。

修改点：

• 在您的脚本中，HTN()用作 for 循环。并且该功能包括SpreadsheetApp.getActiveSpreadsheet().getSheetByName(shtName).getDataRange().getValues().shift();. 在您的脚本中，电子表格 和sheetName不会更改。所以headers总是一样的。我认为这可能是主要的修改点。

修改后的脚本：

请按如下方式修改您的脚本。

function AsAboveSoBelow_Offers_Asks() {
  AsAboveSoBelow(
    'Elements',
    ["I can offer", "I have a ask"],
    ["Header1","Header2","Header3","Header4","Header5","Header6","Header7","Header8","Header9","Header10","Header11","Header12","Header13","Header14"],
    "Offers", 
    "Asks"
  );
}

function AsAboveSoBelow(shtName, arrPBV, arrHeaders, newHeader1, newHeader2) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var s  = ss.getSheetByName(shtName);
//  var LC = s.getLastColumn(); // It seems that this is not used.
  var r  = s.getDataRange();
  var v  = r.getValues();
  var start = new Date(); 
  var temp ="";
  //Dim A
  var A = [];
  for (var i = 0; i < v.length; i++) {
    A[i] = [];
    for (var j = 0; j <= arrPBV.length - 1; j++) {
      A[i][j] = '';
    }
  }
  var h = s.getRange(1, 1, 1, s.getLastColumn()).getValues()[0]; // Added
  for(var e = 0; e <= arrPBV.length - 1; e++) {
    var search_Term  = arrPBV[e];
    for(var row = 0; row < v.length; row++) {
      for(var col = 0; col <= arrHeaders.length - 1; col++) {
        var col2 = h.indexOf(arrHeaders[col]) + 1; // Modified
        var replace_Term = arrHeaders[col];
        if(v[row][col2-1].toString().indexOf(search_Term) > -1) {
          temp = temp + replace_Term + "|"
        }
      }
      //remove trailing pipe
      A[row][e] = temp.replace(/\|(?=\s*$)/, '')
      temp = ""
    }
  }
  A[0][0]= newHeader1
  A[0][1]= newHeader2
  s.getRange(1, v[0].length +1, v.length,A[0].length).setValues(A);
  var end = new Date();
  var executiontime = end - start;
  Logger.log(executiontime);
};

笔记：

• 在我的环境中，修改后的脚本的处理时间大约是 5 秒。

如果这不是直接的解决方案，我深表歉意。
