When the user clicks the dropdown menu I need to run some js on iframe content,then I thought that the correct thing to do is this js in my html page:
var scriptTag = "<script>alert("blabla");<"; // saving script to run scriptTag += "/script>"; //add this for fixing the script tag problem $("#myframeid").contents().find("head").append(scriptTag); //appending the script on the head of iframe
But when I run it, the console reports like:
Uncaught SecurityError: Failed to read the ‘contentDocument’ property
from ‘HTMLIFrameElement’: Blocked a frame with origin
“http://localhost:8080” from accessing a frame with origin
“http://www.otherdomainsite.com“. Protocols, domains, and ports must match.
Obviously if it is on a different domain it does not run,so what I have to do now? Am I doing something wrong?
I heard about postMessage ecc.. methods but I never used them.
Thank you in advance.
