JavaScript Wait Until Event Is Completed -


how can execute function after html element gets value ?

i've got number input , getjson using value parameter, getjson loads initial value of number, resulting in null. how can avoid ?

seems if using ajax call desired number getting null. want make sync

if yes then, go ahead , check out

wait until jquery ajax requests done?

or else if using

xhttp.open("get", "ajax_info.txt", true);

use instead xhttp.open("get", "ajax_info.txt", false);
