ext js tabPanel中验证问题

Question

如上图，如果我隐藏掉页面2，提交的时候还是要验证隐藏的才可以，有没有方法使页面2的验证失效，或者把验证删除的方法，初学ext，请大家帮忙看下

Answer 1

每个tab页可以各放在一个form中
你不行 验证tab2的话可以这样
if(form1.form.isValid()&&!form2.form.isValid()){}

Answer 2

{xtype:"textfield",//这里先不写allowBlank:false,
//需要的时候加上验证
Ext.apply(address, { allowBlank: false, blankText: "地址不能为空!" });
Ext.apply(email, { allowBlank: false, blankText: "email不能为空!" });

Answer 3

 var tab2=new Ext.Panel({
                        title:'页面2',
                        layout: 'form',
                        defaults: {width: 230},
                        defaultType: 'textfield',
                        items:[{
                                fieldLabel: '地址',
                                name: 'address'
//                                allowBlank: false
                            },
                            {
                                fieldLabel: 'email',
                                name: 'email',
                                allowBlank: false,
                                vtype:'email'
                        }]
                    });
buttons: [{ 
                    text: '隐藏',
                    handler: 
                    function() {
                        Ext.apply(address, { allowBlank: false, blankText: "地址不能为空!" });                    }
                  },{ 
                    text: '按钮',
                    handler: form_submit
                  }]提示 address is undefined

Answer 4

Ext.apply(address, { allowBlank: false, blankText: "地址不能为空!" });
这的address你首先要获取它的对象。还有你的面板是panel 你要改成formpanel
