javascript - Make a function in .replace() -

-

i have following code uses regex:

var mystring = "<<cool>> <<stuff>>" var regexstring = /<<([^\:]{0,})>>/gi  mystring.replace(regexstring, "$1")

i able replace string based on text on capture group. like:

var mystring = "<<cool>> <<stuff>>" var regexstring = /<<([^>]{1,})>>/gi  mystring.replace(regexstring, function(var0) { //var0 being text capture group      if(var0 == "cool") {         console.log("got cool")      } else {         console.log("didn't cool")     } })

is there someway this?

yes, can use function second argument of .replace(). example:

mystring.replace(regexstring, function(match, group1) {      // group1 here });

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
