代码如下：
- JScript code
(function () {
var Ajax = {
_ajax : null,
get : function (url, data, fn) {
this.ajax({
url : url,
data : data,
fn : fn,
type : 'GET'
});
},
post : function (url, data, fn) {
this.ajax({
url : url,
data : data,
fn : fn,
type : 'POST'
});
},
ajax : function (obj) {
typeof obj.data == 'function' && (obj.fn = obj.data, obj.data = {});
if (window.XMLHttpRequest) {
this._ajax = new XMLHttpRequest();
} else {
this._ajax = new ActiveXObject('Microsoft.XMLHTTP');
}
var para = '';
for (var i in obj.data) {
para += i + '=' + obj.data[i] + '&';
}
para = para.substr(0, para.length - 1);
this._ajax.open(obj.type || 'GET', obj.type == 'GET' ?
obj.url.indexOf('?') != -1 ?
(obj.url + '&' + para) :
(obj.url + '?' + para) :
obj.url, true);
obj.type == 'POST' && this._ajax.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
this._ajax.onreadystatechange = function () {
if (this.readyState == 4 && this.status == 200) {
obj.fn(this.responseText);
}
};
this._ajax.send(obj.type == 'POST' ? para : null);
},
abort : function () {
this._ajax.abort();
}
};
window.Ajax = Ajax;
})();
