Remove the <%= if (msg){ %> 把 = in the first line.

<% JavaScript 控制代码，不输出 %>
<%= 输出值 (HTML escaped) %>
<%- 输出值，原样输出 %>

<body>

<% if (msg){ %>
<p><%= msg %></p>
<% } %>

<input id="msg" type="hidden" value="<%= msg %>">

<script>

  var msg = document.querySelector('#msg').value;
  console.log(msg);


  alert(<%= msg%>);
  
  var msg1 = <%= msg%>;
  console.log(msg1);
  
</script>
