書き方

$("#button").click(function(event){ 
    $.ajax({
        type: "POST",
        url: "/slot_allocations/" + slotallocation_id,
        dataType: "json",
        data: {"_method":"delete"},
        complete: function(){
            $( "#SlotAllocationForm" ).dialog( "close" );
            alert("Deleted successfully");
        }
    });
    event.preventDefault();
});

ポイントは、最後らへんにある event.preventDefault(); の記述。
これがないと期待の動作をしてくれない。
