很久之前写的Ajax库

很久之前写的一个小型AJAX的js，放在上面以免以后想玩了找不到了。

 

//  version : 0.1 beta
//  author : __Ajax

function __Ajax(url,options){
    
    var xhr = window.ActiveXObject && new window.ActiveXObject('Microsoft.XMLHTTP') || new XMLHttpRequest();

    //  默认设置
    options.method = options.method || 'GET';
    options.onSuccess = options.onSuccess || function () { };
    options.onFailure = options.onFailure || function () { };
    options.onComplete = options.onComplete || function () { };

    //  状态改变
    xhr.onreadystatechange = function () {

        if (xhr.readyState != 4) return;
        xhr.status == 200 ? options.onSuccess(xhr.responseText, xhr.responseXML) : options.onFailure(xhr);
        options.onComplete();
    }

    xhr.open(options.method, url);

    /*
        beta 代码，备用
    //  解决未设置method的值为默认GET
    //  options.method = options.method || 'GET'
    */

    options.method.toUpperCase() == 'POST' && xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    xhr.send(options.data);

    return xhr;
}

 

使用起来很方便，大家可以拿来玩玩。呵呵。

                    method: 'post',
                    data: 'name=aaaa',
                    onSuccess: function (data) {
                        alert(data);
                    },
                    onFailure: function (xhr) {
                        alert('error');
                    }

                });
            }

        </script>

    </head>
    <body>
        
    </body>
</html>

压缩版

function __Ajax(b,a){var c=window.ActiveXObject&&new window.ActiveXObject("Microsoft.XMLHTTP")||new XMLHttpRequest();a.method=a.method||"GET";a.onSuccess=a.onSuccess||function(){};a.onFailure=a.onFailure||function(){};a.onComplete=a.onComplete||function(){};c.onreadystatechange=function(){if(c.readyState!=4){return}c.status==200?a.onSuccess(c.responseText,c.responseXML):a.onFailure(c);a.onComplete()};c.open(a.method,b);a.method.toUpperCase()=="POST"&&c.setRequestHeader("Content-type","application/x-www-form-urlencoded");c.send(a.data);return c};
