How to get current logged user information using JavaScript ?

This is post which is simple and not really needed. But when I started writing the code in ECMAScript I have faced problems in getting the logged in user information. So, my readers may feel good after see this post and really most the users are looking for this too.
By this time, we have really understood all about ECMAScript Client Object Model and debugging. So, it's easy for us to know it well.
Please find the code below to get the current user information.



<asp:Content ContentPlaceHolderId="PlaceHolderAdditionalPageHead" runat="server">

Now copy & paste this JavaScript code after above mentioned tag :

<script type="text/ecmascript">

        ExecuteOrDelayUntilScriptLoaded(getUserData, "sp.js"); 

       
    // To Get Current User Name
    var context = null; 
    var web = null; 
    var currentUser = null; 
    var currentUserId=''
    function getUserData() {

            context = new SP.ClientContext.get_current(); 
        web = context.get_web(); 
        currentUser = web.get_currentUser(); 
        currentUser.retrieve(); 
        context.load(web);
        context.executeQueryAsync(onSuccessMethod, onFaiureMethodl);
       
    } 
       
    function onSuccessMethod(sender, args) { 
        var userObject = web.get_currentUser(); 
        alert('User name:' + userObject.get_title() + '\n Login Name:' + userObject.get_loginName()); 

    }
   
    function onFaiureMethodl(sender, args) {
        alert('request failed ' + args.get_message() + '\n' + args.get_stackTrace()); 
    }
    //--- END Get Current User Name

</script>

i tried to implement this code, but problem is if instead of alerting it i try to document.write te username it writes off the entire page code with the login name?

Thank you so much worked perfectly.

@Mohit Gupta: If you're just wanting to display the username on a page I would recommend writing to a tag:

//outside of Script, had to use [] instead of <>
[a id="test99"][/a]

//in place of alert
document.getElementById("test99").innerHTML = userObject.get_title();

Thank you for this code! It saved me a lot of trouble on a SharePoint project. Using this code, I was able to send the name of the current user to an external program displayed in an iframe on a SharePoint ASPX page.

Hi

What about the extended properties of the User? This code gets the Title, and LoginName - and works well enough - thanks.

But, what about Picture, Notes, etc?

Thank you kindly

Thanks a lot for this great post.
My question, how can I get all the methods for the "Get Current User". I am looking to populate another information like "Email" and "Phone Number".

Thanks again,
Sam
