yellow-screen-of-death xmlhttprequest regex javascript asp.net

我是在 http://regextester.com 解析ysod,但vs抱怨语法错误。我肯定我在某个地方错过了一次逃跑,但我是一无所获。

这是原版的。如有任何帮助,我们将不胜感激。

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

更新: 科比指出了明显的问题,让我再次行动。对于那些感兴趣的人来说,这是一个有效的javascript,可以测试和解析一个用于asp.net死亡黄屏(ysod)的xmlhttprequest.responsetext。

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-这就是我想要解析HTML的结果和原因,尽管我得到了500:

{
 "message": " Unknown web method ValidateUser.\r\nParameter name: methodName\r\n",
 "stackTrace": "at System.Web.Script.Services.WebServiceData.GetMethodData(String methodName)\r\n   at System.Web.Script.Services.RestHandler.CreateHandler(WebServiceData webServiceData, String methodName)\r\n   at System.Web.Script.Services.RestHandler.CreateHandler(HttpContext context)\r\n   at System.Web.Script.Services.RestHandlerFactory.GetHandler(HttpContext context, String requestType, String url, String pathTranslated)\r\n   at System.Web.Script.Services.ScriptHandlerFactory.GetHandler(HttpContext context, String requestType, String url, String pathTranslated)\r\n   at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig)\r\n   at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()\r\n   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)\r\n",

火狐说:

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

在移除 s 它看起来没问题(当然,它没有经过测试,只是被正确地解析了)。

旗 s 在javascript中无效。若要替换,请使用 replace 方法。
