效果: 代码: Ext.onReady(function(){ var attackModeRadios = new Ext.form.RadioGroup({ fieldLabel:'攻击模式', hideLabel:true, //不显示攻击模式 items:[ new Ext.form.Radio({ checked:true, boxLabel:'近战', name:'attackMode', inputValue:'近战' }), new Ext.form.Radio({ checked:true, boxLabel:'远程', name:'attackMode', inputValue:'远程' }) ] }); var form = new Ext.form.FormPanel({ labelAlign: 'right', title: 'form', labelWidth: 50, frame:true, width: 280, items: attackModeRadios, buttons: [{ text: '提交', handler: function() { form.getForm().submit({ success: function(form, action){ //.... }, failure: function(){ //.... } }); } }] }); form.render("form"); }); BODY中加个<div id='form'></div>
