Modal mockup - links to other domains

Plone Support Add-on Development

If I have a modal pop up using the pattern in mockup, links within the current domain work fine. But sometimes I would like to have it go to some external resource. When I try to do this I get blocked by the browser which seems to be an attempt to prevent cross site scripting:

XMLHttpRequest cannot load https://www.google.com/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

Is there some data value I can pass to make this work or is it unsupported?

Long story short, no.

As you probably already understood, this is a security mechanism in your browser that prevents loading third party contents.

You can disable this security. In chrome, for example, running this command:

  • chromium-browser --disable-web-security --user-data-dir

See more here:

If you really want do that, you can proxy the content you want to display with another address or adding the Access-Control-Allow-Origin.

Can you load it in an iframe (?)

I once made something that is slightly related, just dont blame security issues on me :slight_smile:
