While 循環不會停止，即使條件已經滿足。 它又持續了 9 次。 沒有邏輯意義

[英]While loop won't stop, even though the condition has been met. It continues for another 9 times. Makes no logical sense

問題描述

我正在努力解決這個問題，因為它沒有意義。 while 循環的條件不滿足，但它在停止之前繼續執行另外 9 次。 我在 while 循環之前 console.log out 變量“donewithLoads”。 即使它是 True，while 循環也會繼續。 沒有意義，任何幫助表示贊賞。

function gatherLoads() {
  var donewithLoads =
    loadSheet
      .getRange(currentRow, 1)
      .getValue()
      .toString().length == 0;
  console.log('donewithLoads value: ' + donewithLoads);
  console.log('isFound Value: ' + isFound);
  console.log(
    loadSheet
      .getRange(currentRow, 1)
      .getValue()
      .toString().length
  );
  while (donewithLoads == false) {
    //while there are still invoice numbers, do this function.
    var isFound = false;
    var currentLoad = loadSheet.getRange(currentRow, 1).getValue(); //record invoice number to
    currentLoad;
    for (var s in allDispatcherSpreadSheets) {
      //search allDispatcherSheets //iterates through  different dispatcher spreadsheets
      var currentDispatchSpreadSheet = allDispatcherSpreadSheets[s];
      var currentSheets = currentDispatchSpreadSheet.getSheets();
      for (var o in currentSheets) {
        //iterates through different sheets in spreadsheet
        var currentSingleSheet = currentSheets[o];
        if (currentSingleSheet.isSheetHidden() != true) {
          // if sheet is visible and not hidden
          //testerstuff
          var testsheetname1 = currentSingleSheet.getName();
          testsheetname1.toString();
          var testSpreadSheetName = currentDispatchSpreadSheet.getName();
          testSpreadSheetName.toString();
          //currentRow2 is the row in the working single sheet that will  be iterated to find   matching invoice number
          for (
            var currentRow2 = 2;
            currentRow2 <= numRowsDispatchSheet;
            currentRow2++ //iterates through rows in column 14 (invoice)
          ) {
            var currentLoad2 = currentSingleSheet
              .getRange(currentRow2, 14)
              .getValue();
            if (currentLoad2 == currentLoad) {
              //if found
              var targetRange = currentSingleSheet
                .getRange(currentRow2, 1, 1, 15)
                .getValues();
              foundLoads
                .getRange(foundLoadscounter + 2, 1, 1, 15)
                .setValues(targetRange);
              foundLoadscounter++;
              isFound = true;
              if (isFound == true) {
                loadSheet.getRange(currentRow, 2).setValue('found');
                loadSheet.getRange(currentRow, 1).setBackground('green');
                currentRow++;
                processedLoadscounter++;
                console.log(
                  'load found: ' +
                    'row ' +
                    currentRow +

                    foundLoadscounter
                );
                console.log(loadSheet.getRange(currentRow, 1).getValue());
                gatherLoads(); // start function again
                break;
              }
            }
          }
        }
      }
    }
    if (isFound == false) {
      loadSheet.getRange(currentRow, 2).setValue('not found');
      loadSheet.getRange(currentRow, 1).setBackground('red');
    }
    currentRow++;
    processedLoadscounter++;

        foundLoadscounter
    );
    console.log(loadSheet.getRange(currentRow, 1).getValue());
    gatherLoads();
    break;
  }
}

該代碼遍歷了 9 行數據，然后遇到了空白，但仍繼續執行。 該代碼確實有效，它標記負載“找到”或“未找到”並更改顏色。

1 個解決方案

@VLAZ 提出了一個有效的觀點。 這就是我的建議：

步驟 1 不使用變量 doneWithLoad，而是定義並使用 function numLoads 來計算加載次數：

function numLoads(ls) {
//ls is a loadSheet object
return ls.getRange(currentRow, 1).getValue().toString().length;
}

第 2 步在 while 循環控制中調用 numLoads 以在每次迭代時更新其值，如 @VLAZ 所建議的那樣。

while(numLoads(loadSheet) > 0) {
//Your code here
}

相關問題 循環JSON並在滿足條件時停止。 然后計算物體 即使條件已滿足，while循環也不會停止 為什么即使滿足條件，我的if語句也不能正確執行？ jQuery驗證程序繼續，即使未滿足所有規則 即使已發送響應，節點也會繼續執行 函數正確返回，但即使條件最終變為假，也會在while循環中超時 在 if 條件下滿足值后增量計數器不會停止 即使不滿足條件，while循環的結果仍然會發生 在滿足特定條件后，我試圖“啟用”禁用的按鈕。 遇到麻煩 如果在下一個索引處不滿足條件，則停止過濾數組，即使仍有數據可以滿足下一個索引
