LiveView phx_click confirm alert

This should work fine today on latest LiveView and phoenix_html. Update both deps and make sure you import "phoenix_html" in your app.js and then you’re good to go!

This is a workaround, just add an IIFE to the onclick event to call the confirmation alert:

<%= link “DELETE” to: “#”, phx_click: “delete_row”, phx_value: row.id, onclick: "(function(){ if (!confirm('Are you sure?')) {event.stopImmediatePropagation();} }).call(event)" %>

if cancel is clicked, then the function event.stopImmediatePropagation is invoked which stops the rest of the event handlers attached to the same element for the same event type from being executed, i.e. it prevents the phx-click handler to be called.
