Question

I’m trying to access an iframe contents from the document it is contained in, but I’m getting the following error message:

Unsafe JavaScript attempt to access frame with URL
file:///home/user/work/project/foo.html from frame with URL
file:///home/user/work/project/index.html. Domains, protocols and
ports must match.

when I run this code:

$('#iframe_id').contents();

As you can see, both files are stored locally in the same folder, so can’t figure out why it is giving that error.

Answer 1

Chrome as security measures in place around local files. Meaning browsing local files isn’t the same as browsing a web server. I would try hosting them somewhere or install a local web server. There is also some command line switches for chrome to disable the local files security but I have never had much luck with it.

Edit:

comand-line switch as mentioned by El Ronnoco is –allow-file-access-from-files
