JQuery: Get length of JSON reply?
- by Rosarch
In a JQuery getJSON call, how can I tell the length of the JSON that's returned?
function refreshRoomList() {
$.getJSON('API/list_rooms',
function (rooms) {
if (rooms.length > 0) {
$("#existing-room-list").empty();
$("#join-existing-room").text("Join existing room:"); // this shouldn't be here
$.each(rooms, function (index, roomName) {
var newChild = sprintf('<li><a href="room?key=%s">%s</a></li>', index, roomName);
$("#existing-room-list").append(newChild);
});
}
else {
$("#join-existing-room").text("No rooms found.");
}
});
}
For some reason this doesn't work, but if I replace rooms.length > 0 with true, the full list of rooms is printed out.
