If your website uses a custom form that doesn't send the submit event (for example, single-page apps that use React) you can still use SparkLoop by tracking sign-ups manually.
To track sign ups manually, simply call this code:
SL.trackSubscriber(emailAddress);
Make sure to replace the emailAddress argument with the actual email address of the person who signs up.
Below a very simple example that shows how to use the manual tracking:
<form id="form" action="/" method="POST">
<input type="email" name="email" id="email_address">
<button>Sign up</button>
</form>
<script>
var form = document.getElementById('form');
var email = document.getElementById('email_address');
form.addEventListener('submit', function(e) {
// Make sure the SparkLoop library is loaded
if (SL) {
SL.trackSubscriber(email.value);
}
})
</script>
