I want to add JavaScript links to any site urls with iframe. But it returns error like this.
"Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame"
I tried it with javascript.
$('iframe').contents().find('head').append(created_script);
created_script=document.createElement('script');
created_script.src='http://tag-test-super-star.c9users.io/server/js/index.js';
created_script.type='text/javascript';
$('.iframe_tag').contents().find('head').append(created_script);
I think there will be solution with php. Is there any?
