JavaScript: GET Value From Popup (external Website) October 16, 2022 Post a Comment I'm using this code to get a value from a field in popup. http://myotherwebsitename.com/parent.html Open Solution 1: Due to same origin policy you can't get info from another website. here is a better definition of why... In computing, the same-origin policy is an important security concept for a number of browser-side programming languages, such as JavaScript. The policy permits scripts running on pages originating from the same site – a combination of scheme, hostname, and port number[1] – to access each other's DOM with no specific restrictions, but prevents access to DOM on different sites.[1] Same-origin policy also applies to XMLHttpRequest and to robots.txt. http://en.wikipedia.org/wiki/Same-origin_policy. hope this helps. I'll see if I can find a workaround and let you know though.

Here PHP example: if (isset($_SERVER['HTTP_ORIGIN']) && in_array($_SERVER['HTTP_ORIGIN'], $allowedList)) { header('Access-Control-Allow-Origin: ' . $_SERVER['HTTP_ORIGIN']); header('Access-Control-Allow-Methods: POST, GET, OPTIONS'); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Max-Age: 1000'); header('Access-Control-Allow-Headers: X-Requested-With, Content-Type'); exit; } Copy But you should known, that HTTP_ORIGIN contains schema, and you should specify both http and https domains in $allowedList.
