How to add a callback to a function in javascript

Question

I have two javascript functions

function one () {
   do something long... like writing jpgfile on disk
}

function two () {
   do something fast... like show         


        

Answer 1

Try this,

$.when($.ajax(fuction1())).then(function () {

fuction2;

});

Here fuction1 is your first function to call, and fuction2 is your second function.
