Uncaught Error: SECURITY_ERR: DOM Exception 18 whe

Question

I get the following error in Chrome's developer tools window when I try to set a cookie using this jQuery plugin:

Uncaught Error: SECURITY_ERR: DOM Exception 18

What does this error mean and how can I fix it? I get the same error when I use this jQuery plugin.

Answer 1

I had this issue when using the history API.

window.history.pushState(null, null, URL);

Even with a local server (localhost), you want to add 'http://' to your URL so that you have something similar to:

http://localhost...

Answer 2

You can also "fix" this by replacing the image with its inline Base64 representation:

img.src= "data:image/gif;base64,R0lGODlhCwALAIAAAAAA3pn/ZiH5BAEAAAEALAAAAAALAAsAAAIUhA+hkcuO4lmNVindo7qyrIXiGBYAOw==";

Useful, when you do not intend to publish the page on the web, but instead use it on local machines only.

Answer 3

I also had this issue while developping on HTML5 in local. I had issues with images and getImageData function. Finally, I discovered one can launch chrome with the --allow-file-access-from-file command switch, that get rid of this protection security. The only thing is that it makes your browser less safe, and you can't have one chrome instance with the flag on and another without the flag.
