Reading Users From SharePoint Groups via JSOM

As the title suggests, this is a quick example on how to read user details from users in a SharePoint site’s group. Note that the group name must be adjusted within the code to the one you are requesting. To run this script quickly you can just place a Script Editor part on your page and wrap the code in script tags.

function retrieveAllUsersInGroup() {
	
	var clientContext = new SP.ClientContext.get_current();
	var collGroup = clientContext.get_web().get_siteGroups();
	var oGroup = collGroup.getByName("Mikes Group Owners"); //ADJUST THIS LINE!
	this.collUser = oGroup.get_users();
	clientContext.load(this.collUser );

	console.log("Executing query");
	clientContext.executeQueryAsync(Function.createDelegate(this, onQuerySucceeded), Function.createDelegate(this,onQueryFailed));
}


function onQuerySucceeded() {
	console.log("Query success");
	var userInfo = '';

	var userEnumerator = this.collUser.getEnumerator();
	while (userEnumerator.moveNext()) {
		var oUser = userEnumerator.get_current();
		userInfo += '\nUser: ' + oUser.get_title() + 
			'\nID: ' + oUser.get_id() + 
			'\nEmail: ' + oUser.get_email() + 
			'\nLogin Name: ' + oUser.get_loginName() + "<br/></br/>";
	}
	 
	 
	console.log(userInfo);
}

function onQueryFailed(sender, args) {
	alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

SP.SOD.executeFunc("sp.js", null, retrieveAllUsersInGroup);
