Javascript JS未自动填充SharePoint用户

我已经包含了一段代码，它似乎没有达到我想要的效果。在过去，我能够使用它根据SharePoint中的用户名自动填充名称。没有明显的错误，脚本中的所有其他内容都运行良好，并且看起来这确实是，它只是没有达到预期的效果

function getWebUserData() {
        context = new SP.ClientContext.get_current();
        web = context.get_web();
        currentUser = web.get_currentUser();
        currentUser.retrieve();
        context.load(web);
        context.executeQueryAsync(Function.createDelegate(this, this.onSuccessMethod), 
             Function.createDelegate(this, this.onFailureMethod));
}

function onSuccessMethod(sender, args) {
    var userObject = web.get_currentUser();

    $("input[Title='Requester']").val(userObject.get_title());
    $("input[Title='Requester']").attr('disabled','disabled');   
}

以下代码适用于我的本地SharePoint 2013

$（文档）.ready（函数（）{
函数GetCurrentUser（）{
var requestUri=_spPageContextInfo.webAbsoluteUrl+“/_api/web/currentuser”；
var requestHeaders={“accept”：“application/json；odata=verbose”}；
$.ajax({
url:requestUri，
contentType:“application/json；odata=verbose”，
headers:requestHeaders，
成功：一旦成功，
错误：onError
});
}
成功时的功能（数据、请求）{
var userName=data.d.LoginName；
//解析值。
userName=userName.toString（）.split（“i:0.w”）[1]；
SetUserFieldValue（“请求者”，用户名）；
}
函数onError（错误）{
//警报（错误）；
}
函数SetUserFieldValue（字段名、用户名）{
var _PeoplePicker=$（“div[title='“+fieldName+'”]）；
var_PeoplePickerTopId=_PeoplePicker.attr（'id'）；
var_PeoplePickerEditer=$（“输入[title='”+fieldName+'”）；
_PeoplePickerEditer.val（用户名）；
var_peoplepickerobject=SPClientPeoplePicker.SPClientPeoplePickerDict[_PeoplePickerTopId]；
_PeoplePickerObject.AddUnsolvedUserFromEditor（true）；
}
GetCurrentUser（）；
});
