后台代码：
System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
str = serializer.Serialize(actionList);
context.Response.ContentType = "text/plain";
context.Response.Write(str);
前台代码：
$.post("../Ashx/UserActionHandler.ashx?Method=GetUserAction", obj, function (data) {
alert(data);
var jsonlist = eval('(' + data + ')'); //转换后的JSON对象
for (var i = 0; i < jsonlist.length; i++) {
alert(jsonlist[i].userId);
}
});
alert(data);得到的值为
[{"ExtensionData":{},"action":"今天遇到一个很麻烦的问题，现在还没有找到解决方案，真是头疼啊。。。。","actionType":1,"createTime":"2012-08-17 17:44","deleted":0,"id":5,"userId":3494080016379720743},{"ExtensionData":{},"action":"非常hapy啊~","actionType":1,"createTime":"2012-08-17 08:23","deleted":0,"id":4,"userId":3494080016379720743},{"ExtensionData":{},"action":"在北京xxxx公司第一天上班，感觉还不错吆，同事对我都可好了。都可好了。在北京xxxx公司第一天上班，感觉还不错吆，同事对我都可好了","actionType":1,"createTime":"2012-08-17 08:18","deleted":0,"id":3,"userId":3494080016379720743},{"ExtensionData":{},"action":"今天心情很好啊，哈哈哈中~~~","actionType":1,"createTime":"2012-08-17 08:15","deleted":0,"id":2,"userId":3494080016379720743}]
但是
alert(jsonlist[i].userId); 输出的是 3494080016379720700
不明白为什么userid后两位会变成00
有人知道是怎么回事吗？
------解决方案--------------------------------------------------------
"userId":"3494080016379720743"}将UERID变成字符串看看
------解决方案--------------------------------------------------------
明显精度不够了，用字符串吧
