The flow is the same with the Leaderboard module as with the Achievements module. Here is the JavaScript:

function GetLeaderBoard(){
var action='GetLeaderBoard',html='',Username='',Points='',html="<table>";
$.ajax({
dataType: "json",
data: {action:action},
url: $AJAXHANDLER,
success: function (data){
for (var i = 0; i < data.length; i++) { 
if (data[i].UserName==''){Username='Anonymous'}else{Username=data[i].UserName};
Points = data[i].Points;
html+='<tr><td><a href="#">'+Username +'</a></td><td>'+Points+'</td></tr>';  
}
html+="</table>";
$("#leaderboardsdiv").append(html);
},
error: function (xhr, status, error) {

});
}

Here is the associated PHP function:

function GetLeaderBoard(){
$storedProcedure = "Select distinct UserName,Points from Player order by points desc LIMIT 0,5";
$Leaders = array();
$fetch = mysql_query($storedProcedure); 
while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC)) {
