Make table row clickable and pass a post parameter to jquery function

Question

I have created a table and filled it with elements taken through JSTL tag and EL expression like this

<c:forEach items="${routes_list}" var="route">
    <tr>
       <td>${route.airlane}</td>
       <td>${route.aircraft_id}</td>
       <td>${route.airport_city_source.city}</td>
       <td>${route.airport_city_dest.city}</td>
       <td><fmt:formatDate value="${route.departure_date}" pattern="dd/MM/yyyy hh:mm"/></td>
       <td><fmt:formatDate value="${route.arrival_date}" pattern="dd/MM/yyyy hh:mm"/></td>
       <td>${route.travel_class}</td>
     </tr>
 </c:forEach>

what I would like to do is to make every row clickable. I have achieved this by using this function

$("tr").click(function() {
window.location.href = $(this).find("a").attr("href");
});

but my real goal is to pass to href ${route.id} in order to send a post request to a servlet and make some task. I'm not a jquery programmer so I don't know how to proceed. Thank you folks

EDIT

$(".show_reservations").click(function() { //show.reservations css class
var href  = $(this).find("a").attr("href");
$.ajax({
    cache:false,
    dataType:"html",
    data:"${route.id}="+href,
    type: "POST",
    url: "admin_show_reservations", //NAME OF THE SERVLET
    success: function(data)
             {
                //console.log(data);
                alert("success"+data);
             },
    error: function(exception)
    {
    alert("error");
    }
    });
});

$("tr").click(function() {
var href  = $(this).find("a").attr("href");
 $.ajax({
                cache:false,
                dataType:"html",
                data:"yourparameter="+href,
                type: "POST",
                url: "yourServletContextPath",
                success: function(data)
                    {
                        //console.log(data);
                        alert("success"+data);
                    },
                error: function(exception)
                    {
                    alert("error");
                    }
                });
});

"data" will contain your html type response
