How to get a value of an element by name instead of ID

Question

How could I get the value of an element via the attribute name instead of the ID. eg if I use by id it would be $(\'#id\').val();

Answer 1

This works fine .. here btnAddCat is button id

$('#btnAddCat').click(function(){
        var eventCategory=$("input[name=txtCategory]").val();
        alert(eventCategory);
    });
