Ext 如何获取radio的值？ - Web 开发 / Ajax
有如下代码:

JScript code

{                    id:'ipmac_mod',                                xtype: 'panel',                                layout: 'table',                    fieldLabel: '模式',                     defaultType: 'radio',                    isFormField: true,                    items:                     [                        {                               id: 'type_local',name:'user_type',boxLabel: '模式1',value:'F',checked:editdata.data[0]['close_radius'],                               listeners:                                {                                check: function(radio,checked)                                 {                                    if(checked == true)                                    {                                                                                                                        Ext.getCmp('radius').hide();                                        Ext.getCmp('local').show();                                                                                                                }                                }                               }                          },                          {                            id: 'type_radius',name:'user_type',boxLabel:'模式2',value:'D',checked:editdata.data[0]['open_radius'],                            listeners:                             {                                check: function(radio,checked)                                 {                                    if(checked == true)                                    {                                        Ext.getCmp('local').hide();                                        Ext.getCmp('radius').show();                                                                            }                                }                               }                          }                     ]                }

JScript code

Ext.override(Ext.form.RadioGroup, {       getValue: function(){           var v;           if (this.rendered) {               this.items.each(function(item){                   if (!item.getValue())                        return true;                   v = item.getRawValue();                   return false;               });           }           else {               for (var k in this.items) {                   if (this.items[k].checked) {                       v = this.items[k].inputValue;                       break;                   }               }           }           return v;       },       setValue: function(v){           if (this.rendered)                this.items.each(function(item){                   item.setValue(item.getRawValue() == v);               });           else {               for (var k in this.items) {                   this.items[k].checked = this.items[k].inputValue == v;               }           }       }   });
[解决办法]
JScript code
var type;//结果var typeObj = Ext.getCmp("ipmac_mod");    if(typeObj){    for(var i =0;i<2;i++){          if(typeObj.items.items[i].checked){        type = typeObj.items.items[i].inputValue;          }       }      }
[解决办法]
JScript code
var type_local=Ext.getCmp('type_local').getEl().dom   ,type_radius=Ext.getCmp('type_radius').getEl().dom;if(type_local.checked)alert(type_local.value);else if(type_radius.checked)alert(type_radius.value);else alert('没有选择！');
