javascript – 用于循环跳过条目

作者:互联网

我有一个谷歌应用程序脚本,通过For循环从谷歌应用程序表中提取数据,然后将每一行放入一个阵列准备导出到外部API.我的问题是脚本跳过一些条目,我无法理解为什么.

这是整个代码:

function prepEmails() {
  var ss       = SpreadsheetApp.getActive();
  var s        = ss.getSheetByName("Emails");
  var sLastRow = s.getLastRow();
  var scriptProperties = PropertiesService.getScriptProperties();
  var logCount = scriptProperties.getProperty('EmailCount');
  Logger.log("63 logCount = "+logCount);

  var url          = "https://apitoexportto.com";
  var recordType   = "email";
  var logKey       = "mailCount"
  var activityDesc = "######"    

  if (logCount === null) {
     scriptProperties.setProperty('EmailCount', 0);
     logCount = 0;
  }

  Logger.log("68 logCount = "+logCount);
  var msgs = sLastRow - logCount;
  var arr     = new Array();

  for (var i=0; i<msgs-1; i++) {
    Logger.log("78 inside FOR loop");
    var nextRow = logCount+1; //+1 to skip header row
    var msg     = s.getRange(nextRow+1, 1, 1, 6).getValues(); //+1 to skip to next row

    var payload = {
      'type' : "TimeEntry",
      'matter_id' : msg[0][0],
      'price' : msg[0][1],
      'date' : msg[0][2],
      'note' : msg[0][3],
      'quantity' : msg[0][4],
      'activity_description_id': activityDesc
    };

    arr.push(payload);
    var logCount = parseInt(logCount)+1;
  }
  Logger.log("95 logCount = "+logCount);

  if (i>0) {  
    exportEmails(url, recordType, arr, logKey, activityDesc);
  }
}

这是执行记录:

正如您所看到的,它开始从第98行抓取值.这是基于logCount的预期(一个脚本属性跟踪导出的总数并根据该数字在适当的行中拾取).但随后它跳过99和100并从第101行抓取.这些行中的数据没有什么异常. (行不是空白或类似的任何奇怪).我确认第99行和第100行的值未通过下一个函数导出.他们刚被跳过.

我对javascript相对较新(并且完全是自学成才的),但这对我来说似乎是一个简单的循环.没有继续,没有休息,没有回报.我无法理解它会在哪里或为什么会像这样跳过.

任何人都可以告诉我为什么这些行会被跳过?

解决方法:

我会改变这一行:

var nextRow = logCount+1; //+1 to skip header row

至:

nextRow = nextRow + 1; //+1 to skip header row

并给nextRow一个初始值超过For循环:

var nextRow = logCount - 1; //initialize nextRow

for (var i=0; i<msgs-1; i++) {
    Logger.log("78 inside FOR loop. Value of nextRow: " + nextRow);
    nextRow = nextRow + 1; //+1 to skip header row
    var msg     = s.getRange(nextRow+1, 1, 1, 6).getValues(); //+1 to skip to next row

    var payload = {
      'type' : "TimeEntry",
      'matter_id' : msg[0][0],
      'price' : msg[0][1],
      'date' : msg[0][2],
      'note' : msg[0][3],
      'quantity' : msg[0][4],
      'activity_description_id': activityDesc
    };

另请参阅我对Logger.log所做的更改(“FOR循环中的78. nextRow的值:”nextRow);声明.
