I’ve some peoplepicker in sharepoint page and i need to get the user value of each one. I’ve used this page code to create the pickers. The script in the page retrieve the user id of a Picker control and put it into a div section using this function:

function getUserId(loginName) {  var context = new SP.ClientContext.get_current();  this.user = context.get_web().ensureUser(loginName);  context.load(this.user);  context.executeQueryAsync(  Function.createDelegate(null, ensureUserSuccess),  Function.createDelegate(null, onFail));   }  function ensureUserSuccess() {      $  ('#userTemp').html(this.user.get_id());  }  function onFail(sender, args) {  alert('Query failed. Error: ' + args.get_message());  }   

There is a way to make this function reusable? Something like:

var FirstUserId  = getUserID('superman@superheroes.com');  var SecondUserId  = getUserID('batman@superheroes.com'); 

Thanks to everybody Marco
