How to load several users by array of login names CSOM

Question

I have a dynamically created array of user logins, I would like to retrieve information about these users through CSOM. I found this great post, but there is explanation how to retrieve all users from group. How can I specify that I need to retrieve info only for users in my array?

Answer 1

For my project I used User Information List, but I don't think that it is a good solution

var peoplePicker = SPClientPeoplePicker.SPClientPeoplePickerDict[clientId + "_TopSpan"];
var users = peoplePicker.GetAllUserInfo();

var _ctx = new SP.ClientContext(_spPageContextInfo.webAbsoluteUrl);

var expressions = new Array();
for (var i = 0; i < users.length; i++) {
    expressions.push("<Eq><FieldRef Name='Name' /><Value Type='Text'>" + users[i].Key + "</Value></Eq>");
}

var query = new SP.CamlQuery();
query.set_viewXml("<View><Query><Where>" + buidQueryFromExpressions(expressions) + "</Where></Query></View>");

var list = _ctx.get_web().get_siteUserInfoList();

_loadUsers = list.getItems(query);

_ctx.load(_loadUsers);
