Using Clicky from a Chrome Extension

When I try to use the Clicky embed code inside a Chrome extension, I get the following error:

Error: Code generation from strings disallowed for this context
at _ins.get_cookie (
at _ins.beacon (
at _ins.log (

This appears to be caused by the Clicky code using a Function constructor with String, as described here:

Is generating code like that really necessary and could this be fixed at your end?

The code isn't going to work in an embedded environment like that. It's not designed to. Sorry.

I don't understand why your JS code needs to use eval(). It's a security risk.

This is the current code causing a problem with the eval line:

this.get_cookie = function (name) {
var ca = document.cookie.split(';');
for (var i = 0, l = ca.length; i < l; i++) {
if (eval("ca[i].match(/\b" + name + "=/)"))return decodeURIComponent(ca[i].split(name + '=')[1]);

Why not replace the eval line with:

if (ca[i].match(new RegExp("\b" + name + "="))return decodeURIComponent(ca[i].split(name + '=')[1]);

There are issues with escaping in this forum, there should be two characters before the b in the regex.

This change is live now.
