How to add a Safari toolbar button that runs an AppleScript

Question

How do I add a button to the Safari toolbar that, when clicked, executes a given AppleScript?

Answer 1

I don't think it can be done unfortunately. To put a button on the toolbar, you need to write a Safari Extension, which are restricted in what they can do. They can't execute any sort of arbitrary code outside of Safari. You can read more on developer.apple.com.

Answer 2

Another solution, and this is really dependant on what you want to do, is to use Services to execute your Applescript.

It doesn't create a toolbar icon, but will allow you to create a service from your AppleScript. You can then define a shortcut key in the System Preferences Keyboard Services pane

This page over at automatedworkflows.com shows an example as well as a link to the rather useful ThisService program.
