Answer 1

If you want to use the following on your server:

app.get('/gotospecific', function(req, res) {
    var topic = req.query.topic;
    ...
})

then you'll need this in EJS:

<% pp.forEach(function(a) { %>
    <h1><a href="/users/gotospecific?topic=<%= a.title %>"><%= a.title %></a></h1>
<% }); %>

where pp is assumed to be an array of objects that have title properties. eg

res.render('myview', {pp: [{title: 'First item'}]});

Answer 2

The right syntax for ejs is :

<% pp.forEach(function(a){ %>
  <h1><a href="/users/gotospecific/"+<%= a.title %>+""><%= a.title %></a></h1>
<% }); %>
