	 * $_post():jquery处理ajax中的post请求
	 * 基本语法:$.post(url, data, success, dataType)
	 * 参数说明: 
	 * 		url: 请求的地址
	 * 		data: 需要发送到服务器端的数据
	 * 		
	 * 		success(data,status,xhr): 执行成功的回调函数,
	 * 		回调参数: 1.data: 从服务器端返回的数据
	 * 				 2.status: 当前请求的状态
	 * 				 3.xhr: ajax对象
	 * 		通常我们只关心返回的数据:data
	 *
	 * 		dataType: 从服务器返回数据的格式
	 * 		xml, html, script, json, text, _default
	 * 		通常是'json',可省略,由系统自动判断
	 *
