Obtenez un nom d'utilisateur à partir de leur identifiant

Question

Dans le cadre de mon application hébergée SharePoint, j'utilise une liste contenant une personne ou un groupe.Je reçois l'identifiant de la personne en utilisant ce qui suit.

var ApproverID = currentItem.get_fieldValues()["Approver"].get_lookupId();

à partir d'ici, je veux maintenant obtenir le nom de la personne ou "displaytext" mais peut trouver quelque chose de côté client qui le fait dans MSDN.

peut-il être fait?

Answer 1

I assume in your example Approver is a User field type. In SharePoint 2013 CSOM SP.FieldUserValue object represents the value of a user field for a list item.

The following code demonstrates how to get User Name from User field:

//Get user field value
var assignedToVal = item.get_item('AssignedTo');
var userName = assignedToVal.get_lookupValue();   
console.log(userName);


//Get multi user field value
var assignedToVals = item.get_item('AssignedTo');
for(var i = 0; i < assignedToVals.length;i++) {
     var userName = assignedToVals[i].get_lookupValue();   
     console.log(userName);
}

You need to reference following JavaScript file:

<SharePoint:ScriptLink ID="ScriptLink2" name="SP.UserProfiles.js" runat="server"
    ondemand="false" localizable="false" loadafterui="true" />

Than you can access the User Profile Properties as follows:

var personProperties;

// Ensure that the SP.UserProfiles.js file is loaded before the custom code runs.
SP.SOD.executeOrDelayUntilScriptLoaded(getUserProperties, 'SP.UserProfiles.js');

function getUserProperties() {

    // Replace the placeholder value with the target user's credentials.
    // var targetUser = "domainName\\userName";
    var targetUser = currentItem.get_fieldValues()["Approver"].get_lookupValue();

    // Get the current client context and PeopleManager instance.
    var clientContext = new SP.ClientContext.get_current();
    var peopleManager = new SP.UserProfiles.PeopleManager(clientContext);

    // Get user properties for the target user.
    // To get the PersonProperties object for the current user, use the
    // getMyProperties method.
    personProperties = peopleManager.getPropertiesFor(targetUser);

    // Load the PersonProperties object and send the request.
    clientContext.load(personProperties);
    clientContext.executeQueryAsync(onRequestSuccess, onRequestFail);
}

// This function runs if the executeQueryAsync call succeeds.
function onRequestSuccess() {

    // Get a property directly from the PersonProperties object.
    var messageText = " \"DisplayName\" property is "
        + personProperties.get_displayName();

    // Get a property from the UserProfileProperties property.
    messageText += "<br />\"Department\" property is "
        + personProperties.get_userProfileProperties()['Department'];
    $get("results").innerHTML = messageText;
}

// This function runs if the executeQueryAsync call fails.
function onRequestFail(sender, args) {
    $get("results").innerHTML = "Error: " + args.get_message();
}
