javascript - dart2js's output causes "null is not an object" -


after running 

private/dart/dart-sdk/bin/dart2js -m -o public/js/script.js private/dart/script.dart

the resulting javascript returns 

typeerror: 'null' not object (evaluating 'j.re(a).gvs')

however, error while not minified is

typeerror: 'null' not object (evaluating 'j.getinterceptor$x(receiver).get$onblur')

which might more meaningfull.

it whether use script.js, or script.compiled.js.

the dart code is

import 'dart:html'; import 'dart:core';  void main() {    queryselector("#authorinput").onblur.listen(updatesurname); } void updatesurname(event e){    string author = (e.target inputelement).value;    string surname = author.split(' ').last;    queryselector("#surnameinput").text = surname; }

the relevant haml is

  .form-group      %label(for="authorinput") author      %input.form-control#authorinput(type="text" name="author" placeholder="enter author")   .form-group      %label(for="surnameinput") surname      %input.form-control#surnameinput(type="text" name="surname" placeholder="enter surname")

i believe should work is, though that's not case.

figured out.

i included compiled javascript file inside tag of html page. moving bottom of body fixed everything.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
