为什么我的 ruby 标签无法在 js erb 文件中被识别？

Question

The file is saved as application.js.erb I am trying to use some ruby code as a condition to run my sweet alert.

import { initSweetalert } from '../plugins/init_sweetalert';


if (<% !@user.clients.last.present? %>)
initSweetalert('#sweet-alert-location', {
  title: "Location Alert",
  text: "Location can not be changed until you have clicked start",
  icon: "warning"
});

The ruby tags are not being recognised in my code

Any Help would be greatly appreciated

Answer 1

replace

<% !@user.clients.last.present? %>

with

<%= !@user.clients.last.present? %>

You forgot equal sign
