Is there a way i can get a currently logged in user in a custom button running on javascript?

I have custom button on where i am trying to update certain fields like activated by. Is there a way i can get in a currently logged in user in the javascript?





var retVal = confirm("Are you sure?");
var OrderObj = new sforce.SObject("Order__c");
OrderObj.id = '{! Order__c.Id}'; /* Need Id field to update Order*/
OrderObj.Status__c = 'Activated'; /* Change status */
OrderObj.Activated_By__c= {!User.Id};

/* update method takes an array of Orders; init to 1 element - 'OrderObj' */
var result = sforce.connection.update([OrderObj ]);

if (result[0].success == 'false') {
else {
location.reload(true); /* redisplay the detail page */

Here is the error

You can use a global User object:

<a href="/{!$User.Id}">{!$User.Alias}</a>

In a custom button set the Behavior to "OnClick JavaScript", add following javascript location.href = "/{!$User.Id}" and add the button to the page layout:

  • No idea how to use it in Custom Javascript button

    @Prady just do OrderObj.Activated_By__c= "{!User.Id};" to ensure that those assigned variable is string
