Events

  • ⚠️ In the v0.32.0 release, global events are removed and all the existing events are updated. See the the migration guide.

All the File Uploader events are dispatched on the lr-upload-ctx-provider tag. You can catch them with the native addEventListener method.

Attribute ctx-name is required for the lr-upload-ctx-provider tag, see Context for more details.

<lr-upload-ctx-provider ctx-name="my-uploader"></lr-upload-ctx-provider>

<script>
  const ctx = document.querySelector('lr-upload-ctx-provider')
  ctx.addEventListener('change', e => {
    console.log(e.detail)
  })
</script>
