Inline events helper 
This small script watches your page for any element with a data-simple-event-attribute and automatically sends events to Simple Analytics when the user interacts. You don’t need to write any extra JavaScript calls—just add the right attributes to your HTML.
Warning, this script is in beta and can change any time.
Installation
Include the tracker snippet somewhere on your page, just before the closing </body> tag.
<script async src="https://scripts.simpleanalyticscdn.com/latest.js"></script>
<script async src="https://scripts.simpleanalyticscdn.com/inline-events.js"></script>
Tracking button clicks
To track a click, add data-simple-event="event_name" to any clickable element. The script prevents the default action, sends your event, then continues with the click (including opening links).
<a href="/pricing" data-simple-event="visit_pricing_page">See pricing</a>
Tracking form submissions
Simply put data-simple-event="form_name" on your form tag. When the user submits, the script send an event with the name of the form and the text of the submit button, then submits the form.
<form action="/signup" data-simple-event="signup_form">
<input name="email" type="email" />
<input name="password" type="password" />
<button type="submit">Sign up</button>
</form>
Adding custom metadata
Any attribute starting with data-simple-event- will be included as event metadata. Dashes convert to underscores.
<button
data-simple-event="select_plan"
data-simple-event-plan="enterprise"
data-simple-event-referrer="homepage"
>
Choose Enterprise
</button>
Manual event tracking
You can also fire events from code using sa_event("event_name", { key: value }). This works before or after the auto‑binding. For this you don’t need this extra script.
// custom event on newsletter popup
sa_event("newsletter_signup", { source: "modal" })
404 detection
On DOMContentLoaded the script checks for “404” in your page HTML. If it finds it and the server HEAD request confirms status 404, it will send a page_404 event with the URL and status code.
