jQuery Ajax在不同的端口上

Question

My php file located at port 80 (default port) while my ajax call are on port 8080.

My index.html on port 8080

$(document).ready(function(){
$.get("userCheck.php", 
        {"username" : "lazy", "favcolor" : "FFFFFF" },          
        function(data){ alert("Data Loaded: " + data);
});

My PHP

$user = $_GET["username"];
if($user == "lazy")
    echo "SUCESS";
else
    echo "FAIL";

I have googled abit, JSONP came out mostly. Any idea how to convert it to JSONP?

Any way to make it work?

Answer 1

you cannot do that because of the same origin policy. Since the port are different the same origin policy would apply and block your XHR call.

You would have to use a proxy to do such things, you can take a look at JsonP or build your own proxy using curl or copy your code to be on the same port.
