页面代码：
  <td><input id="Age" name="Age" class="mini-combobox" valuefield="id" textfield="text" shownullitem="true" allowinput="true" data="dataAge" /></td>

JS:
function add() {
      var data = form.getData();
      var json = mini.encode([data]);
      if (form.validate()) {
         .......
}

后台取值时，不给combobox选值，后台就没有对应的json数据，其他的input都显示 xxxx:"",combobox的input却什么都没有，选择值后有正确值Age:"27"

我想要的效果是，不选择就传个空值。

不选 [{"Id":"","Code":"","Dept":"1","Post":"","Specialty":"","PositionDemand":"","PostResponsibility":"",...
选 [{"Id":"","Code":"","Dept":"1","Post":"","Age":"18-30周岁","Specialty":"","PositionDemand":"","PostResponsibility":"","EntryTime":"","WorkPlace":...

就好像控件没被激活一样，当我选择一次后，再选择空项，也会有值
