Is there any way to get value in node js server while clicking on div

Here is my EJS file

        <div class="row">
          <% for(var i=0; i < data.result.length; i++) { %>
            <div class="col-25">
              <a href="/plugDashboard">
                <p><img class="img-fluid" src="/images/plugimg.png" alt="Plug Image"></p>
                <p><h3><%= data.result[i].device_name %></h3></p>
                <p><h6><%= data.result[i].device_address %></h6></p>
              </a>
            </div>
          <% } %>

My routes are in the below route:-

app.get('/usrDashboard', checkAuthenticted, (req, res) => {
  let email = req.user.email;
  con.query("SELECT device_name, device_address FROM pluglist WHERE email ='"+ email +"' " , (err, result, fields)=> {
    if(err) throw err;
    console.log(result);
    if (result.length === 0) {
      res.render('usrDashboard',{data:{email: email,
                                        result:result,
                                        noResult:'You have no saved device'}});
    }
    else {

      res.render('usrDashboard',{data:{email: email,
                                        result:result}});
    }
  });
})

app.get('/plugDashboard', checkAuthenticted, (req, res) => {
  console.log(req);
  res.render('plugDashboard');
})

SO here I want, whenever I click on any of the div I want to print the mac id in log from the respective div in plugDashboard section. So is there any way to do so? I searched for many solutions none of them were helpful for me.

Answer

You can add new GET express route, for example:

router.get('/get_mac_info/:mac_id', function(req, res, next) {
  res.json({
    mac_id: 'test_id'

  });
});

and after that just add ajax call on click event:

$(function () {
    $(document).on('click', '.col-25', function (e) {
        $.get('/get_mac_info/' + mac_id, function(data){
          $('.print_container').text(data)
        })
        e.preventDefault();
    });

});
