javascript - setTimeout is not working -

i'm new in javascript , i'm familiar thread.sleep in java. far know, javascript uses settimeout similar thread.sleep.

i'm using phantomjs print thread:

function dothing(i){     settimeout(function(){         console.log(i);     }, 100); }  for(var i=1; i<20; i++){         dothing(i); } phantom.exit(); 

it prints nothing!!

can please let me know, what's wrong here? :(

help appreciated!!

i'm using java program calling phantomjs script.

try this

function dothing(i, last){     settimeout(function(){         console.log(i);         if (last) phantom.exit();     }, 100 * i); }  for(var i=1; i<20; i++){         dothing(i, >= 19); } 

there 2 fixes in code (in comparison origin):

1. phantom.exit() must called after last operation finished (in revision resolved using flag 'last' set true last iteration);
2. it's better call settimeout different timeout values, let them fire 1 one (not critical, still it's better).
