使用JSOM创建新的列表项 [英] Creating new list items with JSOM

问题描述

我收到以下错误:请求失败.来自服务器的意外响应. null"我正在使用SharePoint Online政府.

I'm getting the following error: "Request failed. Unexpected response from server. null" I'm using SharePoint Online Gov.

function getDaysArray(monthNumber, yearString){
//function returns the days of the month 
var yearMonth = "'" + yearString + "-" + monthNumber + "'";

//get the number of calendar days plus one for increment
var numberOfDays = moment(yearMonth, "YYYY-MM").daysInMonth()+1;
//checks if the month number is under 10
if (monthNumber < 10){
//sets month to a string with a zero before it
var vMonth = "0" + monthNumber.toString();
}
else{
//sets month to a string without a leading zero
var vMonth = monthNumber.toString();
}

var daysArray = [];
var iDay = 1;
while (iDay < numberOfDays)
{
//set varibles for weekend and holiday flags
var weekEnd = false;
if(iDay < 10){
var workingDay = yearString + "-" + vMonth + "-" + "0" + iDay.toString();
}
else{
var workingDay = yearString + "-" + vMonth + "-" + iDay.toString();
}

//check for weekend and set flag if it is
if (moment(workingDay).day() == 0 || moment().day() == 6)
{
//set weekend flag to true
weekEnd = true;
}

//skip appointments if weekend
if (weekEnd == false){
//set the days array with the working day date
daysArray.push(workingDay);
} //weekEnd-holiday if statement end

//increment
iDay++;
}//end of days loop - iDay
return daysArray;

}



  function createAppointments(currentYear)
  {
    var listName = "Visitor Calendar";
    var context = new SP.ClientContext.get_current(); // the current context is taken by default here
    //you can also create a particular site context as follows
    var lstObject = context.get_web().get_lists().getByTitle(listName);
    var newItem = null;
var theYear = currentYear.toString();

var m = 1;

//loops through all 12 months

var numWeekDays = datesWeekdays.length;

//loops through all days

推荐答案

请调用createAppoinments函数到另一个没有参数的函数中，然后使用ExecuteOrDelayUntilScriptLoaded调用没有参数的函数，这是供您参考的示例:

Please call place the createAppoinments function in another function which without parameter and then use ExecuteOrDelayUntilScriptLoaded to call the function which without parameter, here is the sample for your reference:

<script src="https://code.jquery.com/jquery-1.12.4.js" type="text/javascript"></script>
<script src="https://momentjs.com/downloads/moment.js" type="text/javascript"></script>
<script type="text/javascript">
