Question

I think my title was informative enough. 🙂

I close the child window like this:

self.close(); 

Just before this, I want the parent window to know that the child has closed. I am making use of this:

window.opener.startLoad(); 

The above will run a function that is on the parent window that I need it to run upon the child window closing.

However, this has led to me getting an error:

Permission denied to get property Window.startLoad
window.opener.startLoad();

Even if I could fix this error, I was told it may be due to JavaScript file being in a different folder and therefore seen as a different domain. Will this work across all browsers? If not, is there a safer solution that is efficient and compatible across all the browsers?

Thank you for any help.

Answer 1

This should work as long as the popup is from the same domain as the parent, otherwise due to security restrictions it will never work. Folder is irrelevant.

if (window.opener && window.opener.startLoad)
{
    window.opener.startLoad();
}
