如果我在jQuery UI对话框中运行表单,如何处理服务器端验证错误？

$("#my-form").submit(function(event) {
  event.preventDefault();
  $.ajax({
    url: $(this).attr("action"),
    type: $(this).attr("method"),
    data: $(this).serialize(),
    success: function(response) {
      if (response.success) {
        alert("表单提交成功！");
        $("#my-dialog").dialog("close");
      } else {
        $("#my-form .error").remove();
        for (var key in response.errors) {
          var error = response.errors[key];
          var input = $("#my-form [name='" + key + "']");
          input.after("<span class='error'>" + error + "</span>");
        }
      }
    }
  });
});
