jquery – 原始http：// localhost不允许Access-Control-Allow-Origin

我有一个问题…我试图得到json api在“http://api.master18.tiket.com/search/autocomplete/hotel?q=mah\u0026amp;token=90d2fad44172390b11527557e6250e50\u0026amp;secretkey=83e2f0484edbd2ad6fc9888c1e30ea44\u0026amp;output=json”

当我尝试离线模式(这意味着我复制json API在记事本和调用它在我的本地主机)与此代码…

function getLast(){
        $.ajax({
            url:"http://localhost/tickets/json/api_airport.json",type:'GET',dataType:"json",success:function(data){console.log(data.results.result[1].category);}
        });
    }

它运行完美。

但是当我尝试真实的url(“http://api.master18.tiket.com/search/autocomplete/hotel?q=mah\u0026amp;token=90d2fad44172390b11527557e6250e50\u0026amp;secretkey=83e2f0484edbd2ad6fc9888c1e30ea44\u0026amp;output=json”)与此代码：

$.ajax({
            url:"http://api.master18.tiket.com/search/autocomplete/hotel?q=mah&token=90d2fad44172390b11527557e6250e50&secretkey=83e2f0484edbd2ad6fc9888c1e30ea44&output=json",crossDomain:true,beforeSend: function(x) {
                if(x && x.overrideMimeType) {
                    x.overrideMimeType("application/j-son;charset=UTF-8");
                }
            },success:function(data){console.log("Success");}
        });

然后在我的google chrome javascript控制台，有一个这样的错误：
“XMLHttpRequest无法加载http://api.master18.tiket.com/search/autocomplete/hotel?q=mah&token=90d2fad44172390b11527557e6250e50&secretkey=83e2f0484edbd2ad6fc9888c1e30ea44&output=json.原因(http：// localhost)不允许Access-Control-Allow-Origin。

我知道，它一定是跨域的问题，有人可以帮我吗？
nb：一些代码，我从堆栈溢出社区….谢谢:)

<?PHP
