asp.net - YSOD 蓝屏死机 JavaScript RegExp - 语法错误

Question

我在 http://regextester.com 建立了这个正则表达式解析 YSOD 但 VS 提示语法错误。我确定我错过了某个地方的逃生，但我一片空白。

这是原始形式。任何帮助表示赞赏。

var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*\n)*?)\s*(at(.*\n)*)-->/gs;

更新: Kobi 指出了显而易见的事实，让我再次行动起来。对于那些感兴趣的人，这是有效的 JavaScript，用于测试和解析 XMLHttpRequest.responseText 以获得 ASP.net 蓝屏死机 (YSOD)。

var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*[\n\r]*)*?)\s*(at(.*[\n\r]*)*)-->/;
if (rxYSOD.test(text)) {
    // looks like one..
    var ysod = rxYSOD.exec(text);
    errObj = { Message: ysod[2], StackTrace: ysod[4], ExceptionType: ysod[1] };
}

@Kobi - 这就是结果，也是我想解析 html 的原因，即使我得到了 500:

Firefox 说:

Error: invalid regular expression flag s
Source Code:
var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*\n)*?)\s*(at(.*\n)*)-->/gs; 

删除 s 后似乎没问题(当然，它没有测试，只是正确解析)。
