Uncaught SyntaxError: Failed to execute 'postMessage' on 'Window': Invalid target origin 'my_page' in a call to 'postMessage'

Question

i have following script

Parent Page(pair_pixel_filter.php):

 window.addEventListener(\"message\", function(e) {
            $(\'#log\')         


        

Answer 1

The 2nd parameter to postMessage is the "target origin". This is the domain where the page is located, not the name of the (php) file.

It needs to be something like:

window.opener.postMessage(data, "http://example.com");
