new Ext.form.RadioGroup和new Ext.form.CheckBoxGroup

extjs2.2中加入了新的组件new Ext.form.RadioGroup和new Ext.form.CheckBoxGroup，这样可以解决以前radio,checkbox组件排版弊端，也可以简洁，隐藏fieldLabel的两种方法：hideLable:true和不给fieldLabel属性并设labelSeparator:"",建议使用后者，

var serviceType = new Ext.form.RadioGroup({
                       width : 220,
                       hideLabel:true,
                       style:'margin-left:100px;',
                       columns : 1,
                       vertical :true,
                       items:[
                              {boxLabel:'本地业务',inputValue:'local',name:'sevType'},
                               {boxLabel:'点对点业务',inputValue:'p2p',name:'sevType',
                           listeners:{
                                check:function(el,checked){
                                   if(checked){
                                     //插入一项
                                        makePointWay();
                                      }else{
                                       //删除一项
                                        removePointWay();
                                              }
                                         }
                                   }
                               }]
                          });

这两个参数可以控制排版，以一列竖型排布。
由于radiogroup没有check事件，可以用radio的check事件，通过这个事件去得到选中，然后就可以去判断了.
有一个问题，就是inputValue的值，在form的submit方法，和load方法都是可以取得和提交正确的值（根据你的inputValue设定的值），但是在本js中要取inputValue的值。好像只能用BasicForm中的getValues()方法，才能取到，原因还不清楚，先取到值再说。
service_FORM.getForm().submit({
                               url:url,
                               method:'post',
                               waitMsg:"提交中",
                               params: {
                                  appid:top.appid
                                     },
                               failure:UI2.formSubmitFailed,
                               success:function(form,action){
                               //取业务类型的值，去判断跳转到那个页面
                                      var dbtypevalue = form.getValues().sevType;
                                 if(dbtypevalue =='local'){
                                        top.dbtype = 'local';
                                       document.location.href = "dbsync-wiz/localdbsync-wiz.jsp";
                                     }else if(dbtypevalue =='p2p'){
                                  var pointwayvalue = Ext.getCmp('pointToPointWayId').getValue();
                           if(pointwayvalue=='src')
                              {
                                document.location.href="dbsync-wiz/point-to-point-src.jsp";
                             }else{
                                 document.location.href="dbsync-wiz/point-to-point-tag.jsp";
}
}
      }，
