javascript - Mozilla form.submit() not working -


i creating dynamic form using following code,

function createform() {     var f = document.createelement("form");      f.setattribute('method',"post");     f.setattribute('action',"./upload");     f.setattribute('name',"initiateform");     f.acceptcharset="utf-8";      var name = document.createelement("input");     name.setattribute('type',"text");     name.setattribute('name',"projectname");     name.setattribute('value',"saket");      f.appendchild(name);      f.submit();  }

but in mozilla nothing happens code works expected ( in chrome). code being called function invoked button on click event. after executing code returning false.

please me out. in advance :-)

you need append new created form document, because not there on page load.

try this:

function createform() {     var f = document.createelement("form");      f.setattribute('method',"post");     f.setattribute('action',"./upload");     f.setattribute('name',"initiateform");     f.acceptcharset="utf-8";      var name = document.createelement("input");     name.setattribute('type',"text");     name.setattribute('name',"projectname");     name.setattribute('value',"saket");      f.appendchild(name);     document.body.appendchild(f); // added     f.submit(); }

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), ...
