Sharepoint学习笔记—ECMAScript对象模型系列-- 9、组与用户操作(二)

   接着上面的继续，这里我们描述的关于User与Group的操作如下：

     6、 向指定Group中添加指定User
     7、 获取指定Group的Owner
     8、 把当前登录用户添加到指定Group中
     9、 判断当前登录用户是否有EditPermission权限
    10、判断当前登录用户是否在某特定的Group中 

  分别描述如下：

     6、 向指定Group中添加指定User

   var siteUrl = '/';
    function addUserToSharePointGroup(groupID) {
        //var clientContext = new SP.ClientContext(siteUrl);
        var clientContext = new SP.ClientContext.get_current();
        var collGroup = clientContext.get_web().get_siteGroups();
        var oGroup = collGroup.getById(groupID);
        var userCreationInfo = new SP.UserCreationInformation();
        userCreationInfo.set_email('helpdesk@GLSTAR.COM.AU);
        userCreationInfo.set_loginName('GLSTAR\\helpdesk');
        userCreationInfo.set_title('helpdesk');
        this.oUser = oGroup.get_users().add(userCreationInfo);  //add user into group
//        var userInfo = '\nUser: ' + oUser.get_title() +
//            '\nEmail: ' + oUser.get_email() +
//            '\nLogin Name: ' + oUser.get_loginName();
//        alert(userInfo);
        clientContext.load(oUser);
        clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededaddUserToSharePointGroup),
        Function.createDelegate(this, this.onQueryFailedaddUserToSharePointGroup));
    }

    function onQuerySucceededaddUserToSharePointGroup() {
        alert(this.oUser.get_title() + " added.");
    }
    function onQueryFailedaddUserToSharePointGroup(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }

 

  7、 获取指定Group的Owner

 //Get The Group Owner Name in SharePoint 2010 Using ECMAScript
    var group;
    function getGroupOwnerName(groupID) {
        var clientContext = new SP.ClientContext();
        var groupCollection = clientContext.get_web().get_siteGroups();
        group = groupCollection.getById(groupID);
        clientContext.load(group);
        clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededgetGroupOwnerName),
                                        Function.createDelegate(this, this.onQueryFailedgetGroupOwnerName));

    }

    function onQuerySucceededgetGroupOwnerName() {
        alert("GroupTitle:  " + group.get_title() + "\nGroupOwnerTitle : " + group.get_ownerTitle());
    }

    function onQueryFailedgetGroupOwnerName(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }

     8、 把当前登录用户添加到指定Group中

 //adds the current user to the specific group on the current website
    var currentUser;
    var visitorsGroup;
    function addUserToSpecificGroupInCurrWeb(groupID) {

        var clientContext = new SP.ClientContext();
        var groupCollection = clientContext.get_web().get_siteGroups();
        visitorsGroup = groupCollection.getById(groupID);
        currentUser = clientContext.get_web().get_currentUser();
        var userCollection = visitorsGroup.get_users();
        userCollection.addUser(currentUser);

        clientContext.load(currentUser);
        clientContext.load(visitorsGroup);
        clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededaddUserToSpecificGroup),
        Function.createDelegate(this, this.onQueryFailedaddUserToSpecificGroup));

    }

    function onQuerySucceededaddUserToSpecificGroup() {
        alert(currentUser.get_title() + " added to group " + visitorsGroup.get_title());
    }

    function onQueryFailedaddUserToSpecificGroup(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }

     9、 判断当前登录用户是否有EditPermission权限

  //Check current user has Edit Permission
    var theCurrentUser;
    var theWeb;
    function checkifUserHasEditPermissions() {
       // debugger;
        var context = new SP.ClientContext.get_current();
        theWeb = context.get_web();
        theCurrentUser = theWeb.get_currentUser();
        context.load(theCurrentUser);
        context.load(theWeb, 'EffectiveBasePermissions');
        context.executeQueryAsync(Function.createDelegate(this, this.onSuccessMethodcheckEditPermissions),
                                  Function.createDelegate(this, this.onFailureMethodcheckEditPermissions));
    }
    function onSuccessMethodcheckEditPermissions() {
        //debugger;
        if (theWeb.get_effectiveBasePermissions().has(SP.PermissionKind.editListItems)) {
            //User Has Edit Permissions
            alert(theCurrentUser.get_loginName()+"Has Edit Permission on current website");
        }
        else {
            alert("No Edit Permission");
        }
    }
    function onFailureMethodcheckEditPermissions() {
        alert("Failed to check permission");
    }

    10、判断当前登录用户是否在某特定的Group中   

   var IsInThisGroupFlag = false;
    // The below checks if the user exists in the group
    function checkIfCurrentUserIsInGroup(groupID) {
        var context = SP.ClientContext.get_current();
        //I go to parent site if I'm in a subsite!
        var siteColl = context.get_site();
        var web = siteColl.get_rootWeb();
        var groupCollection = web.get_siteGroups();

        // Get the Our Group's ID
        var _group = groupCollection.getById(groupID); // ID of the Group that we are checking
        var users = _group.get_users(); // Get all Users of the group
        context.load(_group);
        context.load(users);
        this._users = users;
        this._currentUser = web.get_currentUser(); // Get current user
        context.load(this._currentUser);
        context.executeQueryAsync(Function.createDelegate(this, this.CheckUserSucceededUserIsInGroup),
        Function.createDelegate(this, this.CheckUserfailedUserIsInGroup));
    }

    //The below Checks  if User is the member of the specified group
    function CheckUserSucceededUserIsInGroup() {
        //debugger;
        IsInThisGroupFlag = false;
        if (this._users.get_count() > 0) {
            var _usersEnum = this._users.getEnumerator();
            while (_usersEnum.moveNext()) {
                var user = _usersEnum.get_current();
                if (user.get_loginName() == this._currentUser.get_loginName()) {
                    //debugger;
                    IsInThisGroupFlag = true;
                }

                if (IsInThisGroupFlag) {
                    alert(user.get_loginName() + "  exist in the checked group " + IsInThisGroupFlag.toString());
                }
                else {
                    alert(user.get_loginName() + "  not exist in the checked group ");
                }
            }
        }
    }

    function CheckUserfailedUserIsInGroup() {
            alert('failed');
        }
