Update item in Nintex form using SPService code

I am working on few forms developed in Nintex and need to do some CRUD operations. Here is sample code for update item.

Prerequisite:

You need to provide reference of jquery.SPServices-2014.01.NF.min.js file in your script file.

Solution:

function oData_SaveExitPendingHRO() {

//This line is used to get drop down value
    var closedStatusID = oData_GetIDFromDdl(NWF$('#' + jsCtrl_ddlClosedStatus).val());
    var closedStatus = oData_GetTextFromDdl(NWF$('#' + jsCtrl_ddlClosedStatus).val());

//This one is used to get textbox
    var actionComments = '';
if (typeof(jsCtrl_txtActionComments) != "undefined" && closedStatus !=""){
actionComments = NWF$('#' + jsCtrl_txtActionComments).val();
}

//This one is used to get date field. Then we convert it our required format
    var effectiveDate1 = NWF$('#' + jsCtrl_dtpEffectiveDate).val();
if (typeof(effectiveDate1) != "undefined" && effectiveDate1 != "empty") {effectiveDate1 = oData_ConvertToISOString(effectiveDate1);}

//This one is used to get people picker field.
var varHROSpecialist = NWF$('#' + jsCtrl_pickerHROSpecialist).val();

//This one is used to get id.
    var itemID = NWF$('#' + jsCtrl_txtID).val();

    var currentUserAccountName = NWF$('#' + jsCtrl_txtCurrentUserAccount).val();

// Special call to convert special character in html code
actionComments = encodeXMLSpecialChars(actionComments);

    if (!oData_IsNullOrEmpty(itemID)) {

        //Update Action Closure Section
        NWF$().SPServices({
            operation: 'UpdateListItems',
            async: false,
            listName: 'ListName',
            updates: '<Batch OnError="Continue">' +
            '<Method ID="1" Cmd="Update">' +
            '<Field Name="ID">' + itemID + '</Field>' +
            '<Field Name="ClosedStatus">' + closedStatus + '</Field>' +
            '<Field Name="ClosedStatusID">' + closedStatusID + '</Field>' +
'<Field Name="ActionComments">' + actionComments + '</Field>' +
'<Field Name="EffectiveDate">' + effectiveDate1 + '</Field>' +
'<Field Name="HROSpecialist">' + oData_ParsePeoplePickerValue(varHROSpecialist) + '</Field>' +
            '</Method>' +
            '</Batch>',
            completefunc: function (xData, Status) {
                var lowerStatus = Status.toLowerCase();
                if (lowerStatus != null && typeof (lowerStatus) != "undefined" && lowerStatus != "" && lowerStatus == "success") {                 
alert('Command success');

                    //Redirect after saving
        document.location.href = oData_siteUrl,true;
                }
                else {
                   alert('Command failure');
                }
            }
        });
       
    } else {
        alert('Error. Please contact the Administrator.');
    }
}

function oData_ConvertToISOString(eDateValue) {
    var isoDate = new Date(eDateValue);
    if (eDateValue != null && typeof (eDateValue) != "undefined" && eDateValue != "") {
        var day = isoDate.getDate();
        var mm = isoDate.getMonth() + 1;
        var yyyy = isoDate.getFullYear();
        isoDate = yyyy.toString() + "-" + ("0" + mm).slice(-2) + "-" + ("0" + day).slice(-2) + "T09:00:00Z";
    }

    return isoDate;
}

function oData_ParsePeoplePickerValue(eValue) {
    var pplValue = "";
    if (!oData_IsNullOrEmpty(eValue)) {
        pplValue = eValue.replace(";", "").replace("i:0#.w|", "-1;#");
    } else {
        pplValue = "";
    }

    return pplValue;
}


function encodeXMLSpecialChars(unsafe) {
    if (unsafe == null || typeof (unsafe) == "undefined" || unsafe == "") {
        unsafe = "";
    }

    return unsafe
        .replace(/&/g, "&amp;")
        .replace(/</g, "&lt;")
        .replace(/>/g, "&gt;")
        .replace(/"/g, "&quot;");
}
