Will it better to have post the eventid on modal_type : 'ajax' ?

[normalperson]

case "ajax":
$.ajax({url: url, dataType: "html", async: false,type: "post",data: {'eventid':id}, success: function(data) { modal_body.html(data); }});
break;

It will be easier to retrieve more information from DB to populate and show in the modal.

Not clear. Where? When you click on event or when you fetch events?

When I fetch the event
