脚本在多列循环上运行，如何只回发一次，而不是每列回发一次

Question

我的功能正常

它通过其标题找到一列，然后tt在直径上将一列中的像元值拆分，然后替换这些片段的值，然后将它们重新连接为字符串

并对标题列表中的所有列重复

有点缠绵，但令我惊讶的是它的工作原理还不错

我需要协助的问题是，它在每个标头上发回，怎么使它仅发回一次？

我试图弄清楚，但无济于事

谢谢

function FindRsplace(shtName, frshtName, cheaders, frheaders, dilm1, dilm2) {
  var sheet = SpreadsheetApp.getActive().getSheetByName(shtName);
  var hn =[];
  var fhn = [];

  //Array of column indices from column headers
  for (var k = 0; k <= cheaders.length-1; k++) {

       hn[k] = HTN(shtName,cheaders[k]) - 1;

       fhn[k] = HTN(frshtName,frheaders[k]);

  }

 for (var j = 0; j <= cheaders.length-1; j++) {

 var frSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(frshtName);
 var frLR = GLR(frshtName,frheaders[j],2);  // Get the last row of the Search column NOT of the Sheet
 var frRange = frSheet.getRange(2, fhn[j], frLR, 2);
 var frValues = frRange.getValues(); 

 // Read Height only once
 var maxHeight = Range.getLastRow();

 // Read all values and formulas at once
 var rangeValues = Range.getValues();

 // iterate through all cells in the selected range Look in Sheet
for (var cellRow = 0; cellRow < maxHeight; cellRow++) {
for (var i = 0; i < frValues.length; i++) {

        //FindReplace string fragments
        rangeValues[cellRow][hn[j]] = rangeValues[cellRow][hn[j]].toString().split(frValues[i][0]+dilm1).join(frValues[i][1]+dilm2).trim();

        //Replaceing the last fragment or the only string without dilimeter
        rangeValues[cellRow][hn[j]] = rangeValues[cellRow][hn[j]].toString().split(frValues[i][0]).join(frValues[i][1]).trim();

   }
 }

  Range.setValues(rangeValues);
  SpreadsheetApp.flush();
 } 
}

   FindRsplace(

  ["HeaderA", "HeaderB", "HeaderC"], 
  ["frHeaderA", "frHeaderB", "frHeaderC"]],
