Php+jquery cross-domain submission problem, don't mind it. It's only 20 points.

1: A domain server-side output JSON is as follows

$test = "{name:\" john\ ", message:\" Hello john\ "}"; echo $test;

2: The B Domain Server program is as follows

function SendEmail () {var orderingid = $ ("#orderingId"). Val (); alert (orderingid); $.ajax ({type: "Get", url: "// Www.testB.com/cronemail/cron_expressmail.php?orderingid=2222 ", Cache:false,  dataType:" Jsonp ", Jsonp:" Callbackfun ", Jsonpcallback:" Jsonpcallback ",                 success:function (JSON) {alert (json.message);}})}

But the page tip error:

Reply to discussion (solution)

Ajax can't cross domain, that's the fact that it's indisputable
Your code is only a formal cross-domain and is actually

So the URL must return a valid JS statement
Just a JSON string is not enough.

$test = "{name:\" john\ ", message:\" Hello john\ "}"; Echo $_get[' Callbackfun ']. ' ('. $test. ') ';
