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.
