Programming Phoenix LiveView B10.0: phx-debounce introduced too soon (pages 140 and 146-147)

The code example at the top of page 140 includes the phx-debounce=blur binding:

<.input field={@form[:email]} type="email"
  label="Email" phx-debounce="blur" />

This binding is later explained in “Rate Limit Form Events” on pages 146-147. The explanation implies that the phx-debounce=blur binding should not have been included in the earlier code example.

Let’s use debounce to delay the firing of the phx-change event until a user has blurred the email input field:

<.input field={@form[:email]} type="email"
  label="Email" phx-debounce="blur" />

Now, if you visit /promo and type just one letter into the email field, the error message will not appear prematurely. …

Marked As Solved
