关于mui的ajax跨域请求数据的问题？

请求的ajax这样写的。不是mui.ajax自带跨域功能吗？为什么还会报一个跨域的错误

mui.ajax('http://app.veishu.com/jsonp/courses/all.js', {  
                    data: {  
                        mobile: phone  
                    },  
                    dataType: 'json',  
                    type: 'POST',  
                    timeout: 10000,  
                    success: function(data) {  
                        alert(data);  
                    },  
                    error: function(xhr,type,errorThrown) {  
                        console.log(type);  
                    }  
                });

XMLHttpRequest cannot load http://app.veishu.com/jsonp/courses/all.js. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://192.168.1.13:8020' is therefore not allowed access.
