var data=[];
function loadDoc(){

Answer 1

You'll be advised to add "cors-anywhere" to the questions tags: you'll get more probabilities to find someone who could answer better than me...

... because I have never used this kind of service, so, all I can say is that if targeted "site doesn't send Access-Control-*", it's meaning that they doesn't allow external API call (maybe things as cors-antwhere could workaround that, but you must be aware that's sounds quite illegal or at least irrespectuous ^^).

It's just my point of view ;P You're probably a big boy, it's up to you to decide what to do or not to do :)
