                    Ext.Ajax.request({

                        callbackKey: 'callback',
                        defaultHeaders : 'application/json',
                        params: {
                            //key: '23f6a0ab24185952101705',
                            //q: '94301', // Palo Alto

                                    dataarray = Ext.decode(response.responseText);
                                    weather=dataarray.objects;
                                    panel.updateHtml(tpl.applyTemplate(weather))
                                    panel.getParent().unmask();
                                    },
                        failure : function(response, opt) {
                                     Ext.Msg.alert('Failed', response.responseText);
                                     panel.getParent().unmask();
                                    }       


                    });
                }
            },
            {
                 text:'login',
                 handler: function() {
                     var main = new Ext.Panel({  
                                   title: 'My first panel', //panel's title  
                                   fullscreen: true,
                                   //the element where the panel is going to be inserted 
                                   //html: 'Nothing important just dummy text' //panel's content  
                                   items:[
                        {
                            xtype: 'fieldset',
                            title: 'Login',
                            items: [
                                {
                                    xtype: 'textfield',
                                    label: 'Username',

                                    id  :  'username'
                                },
                                {
                                    xtype: 'passwordfield',
                                    label: 'Password',
                                    name:  'password',
                                    id   :  'password'
                                }
                            ]
                        },
                        {
                            xtype: 'button',
                            text: 'Send',
                            ui: 'confirm',

                            handler: function() {}

                        }
                    ]
                                   });  
                 panel.add(main);
                 alert('test');
                 }
            }
            ]
        }]
    }
});

Now when i click on the tab , previous panel will not be cleared and data will get overlapped there ..... like when i click My profile profile is listed there , after that when i click login profile+ login both will be loaded one overlapping another ...

Answer 1

You should use Ext.tab.Panel for this, define your profile and login panels as items of a parent TabPanel, the switching will be handled by ExtJS. You can use the activate event of a Panel to add custom logic to execute when your tabs get activated.
