    @nopassport1 - Only useful, of course, if the OP is part of the team running `dailymed.nlm.nih.gov`... :-) – T.J. Crowder Jan 20 '20 at 16:21

    There are hundreds of questions about CORS and the SOP on Stack Overflow that already have answers. How, **specifically**, is your question different from (say) [this one](https://stackoverflow.com/questions/37527962/add-cors-header-to-an-http-request-using-ajax)? – T.J. Crowder Jan 20 '20 at 16:22

    You will not be able to do that from JavaScript because that website does not allow CORS. You can get around this if you use a back-end like PHP or ASP.NET then use an HTTP web request from there and parse it. – Jesse Jan 20 '20 at 16:22

You can try to use fetch with proxy to make a request:

var proxy_url = 'https://cors-anywhere.herokuapp.com/';
var main_url = 'https://dailymed.nlm.nih.gov/dailymed/services/v2/drugnames.json?drug_name=as';

fetch(proxy_url + main_url)
    .then(response => response.json())
    .then(data => console.log(data));
