jquery validate和jquery form 插件组合实现验证表单后

<form action="@Url.Action("AddColumns","Content")" method="post" id="AddColumnsForm">
 <div class="form-group js-EditCol" id="AddName">
 <label class="control-label">名称</label>
 <input name="Name" class="form-control" required />
 </div>
 <div class="form-group js-EditCol" id="AddRemark">
 <label class="control-label">备注</label>
 <input name="Remark" class="form-control" />
 </div>
 <div class="form-group js-EditCol" id="AddColumnTypeId">
 <label class="control-label">类型</label>
 <select class="form-control" name="ColumnTypeId" id="AddColumnTypeIdSel" required>
 </select>//下拉列表空置验证之要项目的Value值是空的就认为是空值
 </div> 
 <input type="submit" class="btn btn-primary" value="新增栏目" />
 <input type="reset" class="btn btn-default" value="清空" />
</form>

$(document).ready(function () {
 $("#AddColumnsForm").validate({
 submitHandler: function(form) {
  $(form).ajaxSubmit();
 }
 });
});

$(document).ready(function () {
 $("#AddColumnsForm").validate({
 submitHandler: function(form) {
  $(form).ajaxSubmit({
  suess: function (result) { //表单提交后更新页面显示的数据
   $('#TreeTable').treegrid('reload');
   var d = result.split(';');
   ShowMsg(d[0], d[1], d[2]);
  }
  });
 }
 });
});

$(document).ready(function () {
 $("#AddColumnsForm").validate({
 errorPlacement: function (error, element) {//自定义错误信息显示操作，element是出错的input控件,error可以认为是是包含

  element.next('span.help-block').remove();
  element.after('<span class="help-block">' + error.text() + '</span>');
  element.parent().addClass("has-error");
 },submitHandler: function(form) {
  $(form).ajaxSubmit({
  suess: function (result) {
   $('#TreeTable').treegrid('reload');
   var d = result.split(';');
   ShowMsg(d[0], d[1], d[2]);
