javascript - Assigning Object in function to Variable or call setState w/o this? -
i'm sure rather simple, me being new js , react can't seem find answer this.
basically, have function uses jq animate method act counter of sorts. function looks this:
$({countnum: 99}).animate({countnum: 1000}, { duration: 2000, easing:'linear', step: function() { var counter = math.floor(this.countnum) console.log(counter) }, complete: function() { return 'counter done'; } });
i trying setstate within step
can simulate counter on app counts specific number. in order set state need bind this
object in animate function, can't figure out how access countnum
increases.
any ideas? or approaching totally wrong.
you can assign "this" specific variable before entering in callback
var _mythis = this;
and use "_mythis" call member function/variable
_mythis.myjqfct();
but i'm not sure it's need in case.
