在javascript中写入Access-Control-Allow-Origin：或Origin的位置？

Question

So I came to know by searching that I need to set my Access-Control-Allow-Origin: or Origin tags. But where?? Suggestions were to use these in header.

I can't see find anything that explained this. Can anyone please tell me where to put this tags and how!!

Answer 1

In your PHP file * I guess you have ajax request, etc.*

<?php
header('Access-Control-Allow-Origin : *');
