This is an ejs file, I just write like this, and I just want to have an alert and then jump to another page. But now the question is in the alert, the mes and 'success are separated into 2 lines, and can not jump to the homepage.

<div id='Message'>
<%= message%>
</div>

<script>
    showAlert = function(mes, req, res) {
      alert(mes+ 'success');
      return res.views('Event/home');
    }

    var Message = document.getElementById("Message");
    var me=Message.innerHTML; 
    showAlert(me);
    </script>
