mui

$.post = function(url, successCallback, errorCallback) {
ajax('POST', url, successCallback, errorCallback);
};

var ajax = function(method, url, successCallback, errorCallback) {  
    var xhr = new XMLHttpRequest();  
    var protocol = /^([\w-]+:)\/\//.test(url) ? RegExp.$1 : window.location.protocol;  
    xhr.onreadystatechange = function() {  
        if (xhr.readyState === 4)  
        {  
            if ((xhr.status >= 200 && xhr.status < 300) || xhr.status === 304 || (xhr.status === 0 && protocol === 'file:'))  
            {  
                successCallback && successCallback(xhr.responseText);  
            }  
            else  
            {  
                errorCallback && errorCallback();  
            }  
        }  
    };  
    xhr.open(method, url, true);  
    xhr.send();  
};
