angularjs - Chaining methods with delays in javascript -

-

i'm attempting make piece of code more efficient.

(function() {      sc = angular.element('tbody').scope(); sc.draft.resetroster(); sc.$apply();      settimeout(function() {         sc.draft.rosteradd({id: "12921", salary: 10600, position: "p"});sc.draft.rosteradd({id: "12123", salary: 2900, position: "c"});sc.draft.rosteradd({id: "5435", salary: 3800, position: "1b"});sc.draft.rosteradd({id: "12562", salary: 2400, position: "2b"});sc.draft.rosteradd({id: "38321", salary: 3100, position: "3b"});sc.draft.rosteradd({id: "6319", salary: 2400, position: "ss"});sc.draft.rosteradd({id: "5204", salary: 3200, position: "of"});sc.draft.rosteradd({id: "5222", salary: 2500, position: "of"});sc.draft.rosteradd({id: "12462", salary: 2600, position: "of"});     }, 3000);     settimeout(function() {         document.queryselector('#enterbutton').click();     }, 6000); })();

i'm not entirely familiar angular (actually not @ all). i'm trying create client-side script interacts angular. there's 5 total statements here i'm trying condense little code possible. before first settimeout gets triggered in 3,000ms, need run: sc = angular.element('tbody').scope(); sc.draft.resetroster(); sc.$apply();

after 3,000ms, first settimeout runs. 6,000ms (assuming there's ~3,000ms gap between first settimeout , second settimeout) need second settimeout execute.

is there better way put function? less code? better sequencing of how i'm handling settimeout in general?

instead of settimeout use angular service $timeout functions returns promise resolved after specified amount of time has elapsed, , calls $apply. in case: 

$timeout(function () { ... }, 3000).then(function () {     //after first timeout set 1 , return promise     $timeout(function () { ... }, 3000); });

this way rid off mental arithmetic , can set time want wait after last timeout has elapsed, without nesting timeout functions.

i learning perl. trying in debugger define variable, here-document. not know how enter same code in perl script, in debugger. due new lines present inside eot, makes hard in interactive debugger. here small example. have script: >cat ex1.perl #!/usr/bin/perl -w $s =<<'eot'; first line second line eot print $s now run , gives expected output: >perl ex1.perl first line second line now want same in debugger. tried this: >perl -de0 loading db routines perl5db.pl version 1.39_10 db<1> $s =<<'eot';\ cont: first line\ cont: second line\ cont: eot can't find string terminator "eot" anywhere before eof @ (eval 6) [/usr/share/perl/5.18/perl5db.pl:732] line 2. @ (eval 6)[/usr/share/perl/5.18/perl5db.pl:732] line 2. eval 'no strict; ($@, $!, $^e, $,, $/, $\\, $^w) = @db::saved;package main; $^d = $^d | $db::db_stop; $s =<<\'eot\'; first line second line eot; ' called @ /usr/share/perl...

javascript - Create websocket without connecting -

-
is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
