步步为营-78-新闻展示(Ajax+Json+easyUI)
Json:JavaScript Object Notation
1.1 Json对象的接收处理

2.1 列表展示:主要是后台获取数据=>传递给前台转成json对象=>拼接成HTML代码附加到table表中
需要注意两点:
//1 专门实现序列化和和反序列化,很方便
System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
string str = js.Serialize(newsList);
//2 将序列化成json格式后日期(毫秒数)转成日期格式
function ChangeDateFormat(cellval) {
var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/", ""), 10));
var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
return date.getFullYear() + "-" + month + "-" + currentDate;
}
