jQuery JSON and AJAX for off-domain content
Your jQuery code looks like this:
$.ajax({
dataType: "jsonp",
json: "callback",
url: "http://<?=$paths['host']?>/event_registration/how_many_registered.ws.php?event_id=<?=$event['event_id']?>",
success: function(json){
if(json["max"] > 0){
if(json["status"] == "open"){
document.getElementById("registration_container").innerHTML = document.getElementById("registration_container").innerHTML + " - " + json["spaces"] + " places left.";
}
else{
document.getElementById("registration_container").innerHTML = "%lt;a name=\"sorry\" style=\"color: #ee174c\">Sorry. Registration closed. This event is full</a>";
}
}
}
});
The PHP looks like this (where $r == $_REQUEST):
print $r['callback'].'( '.json_encode($reply).' )';
