javascript - How to pass Event (e) and variables with event listeners? -


i have event listener this:

div.addeventlistener('mouseover',function(){bubble_info.call(data);},false);  function bubble_info(e,info){   //get e.pagex etc   //do stuff info }

this problem in bubble_info variable e holds info of data , info undefined

how make sure can e , info correctly?

event object has many useful properties , methods.

div.addeventlistener('mouseover',function(event){     bubble_info(event, info);      // can pass additional params can used in handler  },false);  function bubble_info(event, info){   // can access type of event event object's properties   console.log(event.type);   console.log(info); // additional parameter. };

addeventlistener documentation

use call if need pass reference of this (current) object. it's syntax ...

functionname.call(thisarg, arguments-list, ...);

call documentation

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), ...
