I am having trouble with AJAX:
In document ready i have:
$.post("test.php", function(data){alert('Success');});
and test'php is just <?php ?>...the alert never comes up
This is just a test... In addition to the callback not working, when
the php file updates a mySQL database, those updates are never made.
Why could this be? I'll put all my js code below:
id=0;
p1uid = 0;
p2uid = null;
multiplayer = false;
diff=3;
p1=true;
lock = false;
intID = 0;
cash = 500;
hisCash = 500.5;
turn=0;
bid=0;
hisBid=0;
localturn=0;
$(function() {
if(multiplayer){
$('input.mult').hide();
$('select.mult').hide();
}id = $('form').attr('id');
$.post("test.php", function(data){alert('Success');});
//intID = setInterval("cycle()", 5000);
});
function cycle(){
if(!lock){
localturn = turn;
updateLocals();
if(turn != localturn) play();
if(turn > 4) clearInterval(intID);
}
}
function play(){
if(turn == 0 || turn == 2){
$('input.msg').val("Enter a Bid");
}else if(turn == 3){
$('input.msg').val("He bid " + stringify(hisBid) + ".

move!");
}else if(turn == 1){
$('input.msg').val("Waiting for opponent to bid.");
}else if (turn == 4){
$('input.msg').val("He bid " + stringify(hisBid) + ".

if(!multiplayer) compMove();
