MS格式的Date转换为Json格式的Date 2010/01/04 No Comments
在开发B/S项目时，使用到Ajax已经是司空见惯了，一般我们都是用Json作为数据传输的格式。
在 .Net 中，我们可能用 Web Service 或者 WCF 来进行Json数据传输，这样传输到客户端的 Date 格式为：”\/Date(1231231323+0800)\/” 的字符串，这和Json的 Date 格式不一样，这样就可能导致服务器端与客户端的数据传输出错。 那么，这时我们就需要处理一个问题“MS格式的Date转换为Json格式的Date” 或者“Json格式的Date转换为MS格式的Date”。
在解决这个问题前，先要知道 “\/Date(1231231323+0800)\/” 这个字符串代表了什么？其实这个字符串中 1231231323 是当前距离 1970 年 1 月 1 日之间的毫秒数，+0800 这个数字代表了时区，上面这个 MS 格式的日期字符串代表的是“Thu Jan 15 14:00:32 UTC+0800 1970”。
好了，接下来就稍微容易理解了。在Javascript 中 Date 对象有个 getTime() 的方法返回 1970 年 1 月 1 日至今的毫秒数。于是，我们在向 WCF 提交日期数据的时候是需要把 Date 转换为 MS 的格式的字符串：
var dateStr = "\/Date("+date.getTime()+"+0800)\/"
而从 WCF 返回的 Json 数据，我们也要把 MS 的Date格式字符串转换成Json的Date格式 ：
if (o == undefined || o == null)
return null;
if (o.substring(0, 1) == '/')
if (o.match(msdateRe).length > 1) {
return new Date(parseInt(o.replace(msdateRe, '$1')));
}
return Date.parse(o);
over.

CGUA.NET - Hosting Been Closed 1 Comment
Dec 31th, the last day of year 2009 evening, my website(cgua.net) couldn’t been reached…
I can’t resolve the problem, because Jan 1st, 2nd and 3rd was holidays of the New Year’s Day. What I can do just be waiting…
I contact my hosting provider(TODAYNIC.INC) this morning as soon as i arrived at the company, but the girl of TODAYNIC says that there were some keywords which had been forbidden by CNNIC(China Internet Network Information Center), and so I receive the bad news “The hosting was been closed!!!”
But i’ve not post anything which is related to adult, anti-government or anything what had been forbidden by CNNIC, I swear By God!
Now, they are close my hosting and there is no indication that they will re-open it for me…
So sad!
