jQuery选择器无法在不同的SharePoint环境中工作

Question

我有两个不同的sharepoint 2013开发环境A＆amp; B.以下功能仅适用于A。

function SetAndResolvePeoplePicker(fieldName, userAccountName) {

    // alert(userAccountName);

    var _PeoplePicker = $("div[title='" + fieldName + "']");

    var _PeoplePickerTopId = _PeoplePicker.attr('id');

    var _PeoplePickerEditer = $("input[title='" + fieldName + "']");



    userAccountName.split(";").forEach(function (part) {

        if (part !== "" && part !== null) {

            //  alert(part);
            //
            _PeoplePickerEditer.val(part);

            var _PeoplePickerOject = SPClientPeoplePicker.SPClientPeoplePickerDict[_PeoplePickerTopId];






            _PeoplePickerOject.AddUnresolvedUserFromEditor(true);

        }

    });



}

此函数用于使用用户列表填充SharePoint客户端人员选择器。其中fieldName是title属性，userAccountName是Domain \ username半列分隔的列表。 问题出在

var _PeoplePickerEditer = $("input[title='" + fieldName + "']");

此选择器无法返回服务器B中部署的解决方案中的输入控件，但它在服务器A中正常工作。
