How to manipulate dynamic elements?

Question

JavaScript

Good day everyone!
There is Ajax, I write data to value, but later when I access it, it gives the initial empty value<input type="hidden" id="currency">

var currency = $('#currency').val();  // currency пустой

How to assign a value to a variable that was dynamically assigned in input?
Thanks for the help!

Answer 1

Well, in general, Ajax is an asynchronous request, perhaps at the time of reading from the value from the input, it did not have time to be assigned, you need to make sure that the callback function was successfully completed.
and it is desirable to bring its text (callback functions)
