錯誤：Sys.ArgumentNullException：值不能爲空。參數名稱：clientObject

Question

我想從當前用戶的自定義列表中獲取列表計數。但是錯誤：（「Error：Sys.ArgumentNullException：Value can not be null。Parameter name：clientObject」）正在被拋出。代碼的第一部分，我必須得到當前用戶的屬性工作正常。我認爲PopulateEmployeeHeader（currentUser）導致錯誤。

$(document).ready(function(){  
    // Ensure that the SP.UserProfiles.js file is loaded before the custom code runs. 
    SP.SOD.executeOrDelayUntilScriptLoaded(loadUserData, 'SP.UserProfiles.js'); 
    $('#errorBase').hide(); 
    }); 
    var userProfileProperties; 
    var user; 
    function loadUserData(){ 

    //Get Current Context 
    var clientContext = new SP.ClientContext.get_current(); 

    //Get Instance of People Manager Class 
    var peopleManager = new SP.UserProfiles.PeopleManager(clientContext); 

    //Get properties of the current user 
    userProfileProperties = peopleManager.getMyProperties() 

    clientContext.load(userProfileProperties); 

    //Execute the Query. 
    clientContext.executeQueryAsync(onSuccess, onFail); 

    } 

    function onSuccess() { 

    var employeePhoto =userProfileProperties.get_pictureUrl(); 
    PopulateEmployeeHeader(userProfileProperties.get_displayName()); 

    if(employeePhoto !== undefined && employeePhoto !== "" && employeePhoto !== null) 
    { 
     $('#employeePicture').attr('src', userProfileProperties.get_pictureUrl()); 
     } 
     else 
     { 
     $('results').innerHTML = "Picture does not exist in User Profiles list. Please upload your picture.";  
     } 
    } 
    function onFail(sender, args) { 
    alert("Error: " + args.get_message()); 
    } 

var oEmployee; 
function PopulateEmployeeHeader(currentUser) 
{ 
// var queryListItem = '<View><Query><Where><Eq><FieldRef Name="j2ur"/><Value Type="User">'+currentUser+'</Value></Eq></Where></Query></View>'; 
    var queryListItem='<View><Query><Where><And><Eq><FieldRef Name="j2ur" />'+currentUser+'</Eq><IsNotNull><FieldRef Name="j2ur" />'+ 
    +'</IsNotNull></And></Where></Query></View>'; 
     var siteUrl = window.location.protocol + "//" + window.location.host+'/'; 
    var clientContext = new SP.ClientContext(siteUrl); 
    var oEmployees = clientContext.get_web().get_lists().getByTitle('Accounts'); 

    var myquery = new SP.CamlQuery(); 
    myquery.set_viewXml(queryListItem); 
    this.oEmployee= oEmployees.getItems(myquery); 

    clientContext.load(oEmployee); 

    clientContext.executeQueryAsync(
     Function.createDelegate(this, this.onEmployeeSucceeded), 
     Function.createDelegate(this, this.onEmployeeFailed) 
); 
} 

function onEmployeeSucceeded(sender, args) { 

alert(oEmployee.get_count()); 
} 

function onEmployeeFailed(sender, args) { 

alert('Request failed. ' + args.get_message() +'\n' + args.get_stackTrace()); 
} 

})(jQuery);

我真的結束了重寫代碼。下面的作品就像一個魅力:)

var web; 
var user; 
var context; 
var userdisplayName; 
$(document).ready(function(){ 
context = SP.ClientContext.get_current(); 
web = context.get_web(); 
user = web.get_currentUser(); 
context.load(user); 
context.executeQueryAsync(onSuccess, onFail); 
}); 

function onSuccess() 
{ 
var employeePhoto =userProfileProperties.get_pictureUrl(); 
if(employeePhoto !== undefined && employeePhoto !== "" && employeePhoto !== null) 
    { 
     $('#employeePicture').attr('src', userProfileProperties.get_pictureUrl()); 
     } 
     else 
     { 
     $('results').innerHTML = "Picture does not exist in User Profiles list. Please upload your picture.";  
     } 
    } 

PopulateHeader(user.get_title()); 
} 
function onFail() 
{ 
    alert("Error: " + args.get_message()); 
} 

function PopulateHeader(username) 
{ 
var oList = web.get_lists().getByTitle('Accounts'); 
var camlQuery = new SP.CamlQuery(); 
    camlQuery.set_viewXml('<View><Query><Where><Eq><FieldRef Name=\'j2ur\'/>' + '<Value Type=\'User\'>'+ username+'</Value></Eq></Where></Query><RowLimit>1</RowLimit></View>'); 
    this.collListItem = oList.getItems(camlQuery);   
    context.load(collListItem); 
context.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed)); 

} 
function onQuerySucceeded(sender, args) { 

    var listItemInfo = ''; 

    var listItemEnumerator = collListItem.getEnumerator(); 

    while (listItemEnumerator.moveNext()) { 
     var oListItem = listItemEnumerator.get_current(); 
     var empNumber=oListItem.get_item('_x0065_os0'); 
     listItemInfo += "Title : " + oListItem.get_item('Title') + "<br/>"; 
     listItemInfo += "Project : " + oListItem.get_item('_x0069_i43') + "<br/>"; 
     listItemInfo += "EmployeeNumber : " + oListItem.get_item('_x0065_os0') + "<br/>"; 


    } 
$('#employeeNumber').html(empNumber); 
} 

function onQueryFailed(sender, args) { 

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace()); 
}
