Squarespace Form Submission -> Segment "Identify"

formIdentify.js

* helper function to take the form and
* get back a js object with field/value mappings
* ignoring submit fields and fields whose name we can't ascertain
*/

  return Array.prototype.slice.call(form.elements)
    .filter(isInputElement)
    .filter(isNotSubmit)

  return ~labelText.indexOf(' *')
    ? labelText.slice(0, labelText.indexOf(' *'))

*/

document.forms[0].addEventListener('submit', function(e) {
  analytics.identify(serialize(e.target));
  // analytics.track('Submitted Form');

How can I implement this? Add it to advanced -> code injection?

Hi @sperand-io! Thanks for building this. I can't seem to get it to work on Squarespace, though. Can you advise where this code should be injected?

Thx!
