                    /*options of poptrox*/

            <contentDir></contentDir>
    </div>

If i remove setTimeout in link function, code not working. Can explain to me what AngularJs work with this code. Thank you so much.

Answer 1

You should use $timeout provider instead of setTimeout , see: http://www.codelord.net/2015/10/14/angular-nitpicking-differences-between-timeout-and-settimeout/

TL;DR;

Angular won't "know" what happened inside setTimeout , if you use $setTimeout , that callback will be called inside Angular's digest cycle.

EDIT: I missread your question.

Either way you should use $timeout , the reason you need $timeout is because you need angular to create a separate digest cycle, if you leave the code to run synchronously, it won't work as Angular won't be aware of that change. Usually you'll find this:

$timeout(function(){
  // do something I want angular to be aware of. i.e.: a jQuery plugin
}, 0);
