AJAX跨网域请求 [英] AJAX cross domain request
问题描述
我在我的主网域上有我的JavaScript档案,而我想从子网域拨打一些电话。
I have my JavaScript files on my main domain and I want to do some calls from the subdomain.
我已经添加:
url: "http://domain.com/ajax.php"
因此,完整代码是:
$.ajax({
type: "POST",
url: "http://domain.com/ajax.php",
data: {
var1: var1,
var2: var2
},
success: function(data){
}
});
但是在Firebug上,它会将请求显示为红色 。
But on Firebug it shows the request as red and it fails to respond. Also the POST parameters are there as they should.
我应该在子域上创建一个新的JS文件,并添加必要的代码,然后从那里AJAX调用?
Should I create a new JS file on the subdomain and add the necessary codes and do from there the AJAX calls?
EDIT:使用JSONP代码
> localhost / ajax.php (我从 sub.localhost
I am using this on localhost/ajax.php
, which I call from sub.localhost
$.ajax({
dataType: 'jsonp',
data: 'id=10',
jsonp: 'jsonp_callback',
url: 'http://localhost/ajax.php',
success: function (data) {
console.log(data);
},
});
,ajax.php包含:
and the ajax.php contains:
<?php
echo $_GET["id"];
?>
推荐答案
