ajax中的post/get/delete/put請求方法的寫法過於繁瑣，所以現在封裝成如下簡便的形式：

 /**
     * 獲取資料ajax-get請求
     * @author laixm
     */
    $.sanjiGetJSON = function (url,data,callback){
        $.ajax({
            url:url,
            type:"get",
            contentType:"application/json",
            dataType:"json",
            timeout:10000
 
,
            data:data,
            success:function(data){
                callback(data);
            }
        });
    };

    /**
     * 提交json資料的post請求
     * @author laixm
     */
    $.postJSON = function(url,data,callback){
        $.ajax({
            url:url,
            type:"post",
            contentType:"application/json"
 
,
            dataType:"json",
            data:data,
            timeout:60000,
            success:function(msg){
                callback(msg);
            },
            error:function(xhr,textstatus,thrown){

            }
        });
    };

    /**
     * 修改資料的ajax-put請求
     * @author laixm
     */
 

    $.putJSON = function(url,data,callback){
        $.ajax({
            url:url,
            type:"put",
            contentType:"application/json",
            dataType:"json",
            data:data,
            timeout:20000,
            success:function(msg){
                callback(msg);
            },
            error:function(xhr,textstatus,thrown){

            }
        });
    };
    /**
     * 刪除資料的ajax-delete請求
     * @author laixm
     */
    $.deleteJSON = function(url,data,callback){
        $.ajax({
            url:url,
            type:"delete",
            contentType:"application/json",
            dataType:"json",
            data:data,
            success:function(msg){
                callback(msg);
            },
            error:function(xhr,textstatus,thrown){

            }
        });
    };
