/** Ajax 請求的封裝類
 * Example:
 *  //執行個體化一個請求對象
 *  var ajaxObj = new AjaxProxyII();
 *  //設定ajax請求的url
 *  ajaxObj.setRequestUrl("localhost/projectName/path/someAction.action")
 *  //設定回呼函數 回呼函數 要有兩個參function someFunc(data , textStatus);
 *  ajaxObj.setOnSuccess(someFunc);
 *  //設定要傳遞的參數 如果參數是對象形式
 *  ajaxObj.addParaObj(paraObject);
 *  //如果參數為索引值對形勢
 *  ajaxObj.addParameter("key" , value);
 *  //設定同步非同步 預設為非同步
 *  ajaxObj.setAsync(false);
 *  //發送請求
 *  ajaxObj.sendRequest();
