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('[e-mail]); 
   
        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'); 
  
        }
