Added new "Triggers" button type

[lindseydiloreto]

This PR adds a new type of button: Triggers

Instead of being a "radio button in disguise", a trigger acts more like an actual button. As in, you click it and something immediately happens.

There are two types of triggers... "Link" and "JavaScript".

• A link trigger is a straightforward link. Enter the URL of the page you would like to be taken to. You can optionally have the link open in a new window.
• A JavaScript trigger will run whatever JS you specify. Generally speaking, it'll make sense to simply call a function, which would enact more complex behavior.

Button Box is awesome, I hope you find this PR useful! Please let me know if you have any questions. :)

Here's a practical example...

For the JavaScript trigger, emailCustomer would be a custom user function, which could trigger anything they want. That JS function would have to be included separately, but it could be as simple or complex as they need. It could even trigger a controller action... the possibilities are nearly endless!

Just added the ability to parse element tags in links.

EXAMPLES:

A link to view the "notes" of this entry on the front-end...

{url}#notes

JS to send an email about this entry...

sendEntryMessage({id});

---

In the examples above, {url} and {id} will be parsed from the current element. And just like dynamic entry titles, any element field handle can be used.

I will merge this soon, I promise! Just fighting the tide of client work ...

Lol, sounds good. :)

Hi Josh! I don't suppose you've had a chance to look at this yet?

Hey Lindsey, sorry I didn’t have time in the end - I’ve passed this over to @Nav33d who is taking over maintenance of this project. I don’t see any reason why it can’t just be merged, but it probably makes sense to test it out first.

Thanks @joshangell!

Hi @Nav33d! Would you mind taking a look at this PR? I've found this feature to be extremely helpful, and it works beautifully within the larger context of the Button Box plugin.

Please let me know if you have any questions! :)

Hi @lindseydiloreto,

Apologies for the delayed reply! I have now merged the pull request.

Many thanks

Fantastic, thanks @Nav33d!

Would you mind mentioning the Trigger type in the README and/or docs? There are some examples at the top of this thread which you could use on the site.

Let me know if you need anything else from me! :)
