I have a component define by itemid how I can get it in controller

i m new in sencha . i always use id to define my component . but now i want to change it to itemid . and i found the Ext.getcmp('id'), is not work . and when i use Ext.componentquery.query('itemid') ,the console in chrome said Ext.componentquery is not a function. what can i do?
my view code:
Ext.define('ylp2p.view.Main', {
extend: 'Ext.tab.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.carousel.Carousel',
'ylp2p.store.datainterests',
'Ext.Label',
'Ext.List'
],
config: {
fullscreen: true,
tabBarPosition: 'bottom',
scrollable: 'vertical',
items: [
{
title: '首页',
iconCls: 'home',
styleHtmlContent: true,
//true to automatically style the HTML inside the content target of this component (body for panels).
scrollable: true,
layout: 'card',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'ylp2p'
},
{
xtype: 'container',
layout: 'vbox',
items:[
{
xtype: 'label',
itemId: 'datalabel',---------this component is what i want
height: 50,
store: 'datainterests',
tpl: '金额：{data},利息：{earn}',
}//end label
]
}
]//end items
}
]
},//end config
//end listeners
});
my controller code :
Ext.define('ylp2p.controller.viewdata',{
extend: 'Ext.app.Controller',
launch: function(){
console.log('hello ! here is controller launch function');
var storeId = Ext.create('ylp2p.store.datainterests');
storeId.load({
callback: function(records, operation, success){
Ext.each(records, function(record) {
Ext.ComponentQuery.query("main > datalabel").setData({----it cant work . why?
data : record.get('data'),
earn : record.get('earn')
});
});
}
});
}
});
the console error said:
Uncaught TypeError: Ext.ComponentQuery.query(...).setData is not a function

i got it
var label = Ext.ComponentQuery.query('main #datalabel')[0];
label.setData({
data : record.get('data'),
earn : record.get('earn')
});

I found Sencha's own code to use menu.down('#groupMenuItem') to access itemId:'groupMenuItem'. So you should be fine using:
Ext.ComponentQuery.query('#itemid')

Use this.
var label = Ext.ComponentQuery.query('main #datalabel'); -- check on console label should not undefined
label.tpl.updateData -- you will find methods with tpl

How to add links to modal window in ExtJs

I am trying to create a list of links from a data store, and then use an XTemplate to loop through and display all the links in the data store. I am trying to display the links in a modal window. This is my code:
var win;
var tpl = new Ext.XTemplate("<p>Field1: {f1}, Field2: {f2} </p>").compile();
var data = {
f1: 'a',
f2: null
};
if(!win){
win = new Ext.Window({
el:'hello-win',
layout:'fit',
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'component',
autoEl: {
html: '<input type="text">'
},
listeners: {
render: function(_component) {
_component.getEl().on('keyup', function(e) {
//console.log(this);
console.log(this.dom.childNodes[0].value);
});
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data,
renderTo: Ext.get('hello-win')
}
]
});
}
win.show(this);
There are no errors in console, but the links never load. It just shows my modal window and my textbox, but no links. I would put in in a jsfiddle, but I don't know how (I'm new to ExtJs).
How can I display a list of links in this modal window?

You should not define renderTo in you panel config. Component defined in items array will be rendered to parent component automatically.
Your window have two items so you can not use fit layout. This layout can be used only if component have only one child component. You can remove layout definition and Ext JS framework will use auto layout or you can use some layout which support more child items, like hbox, vbox, etc.
Your code should look like this:
var win = new Ext.Window({
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'textfield',
enableKeyEvents: true,
listeners: {
keyup: function(c) {
console.log(c.getValue());
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data
}
]
});
Also you should consider using textfield component instead of creating textfield by using component with autoEl config.

Sencha Touch: Toolbar inside of TabPanel

I'm new to Sencha Touch and just trying to put a Toolbar inside of a TabPanel.
I do that because the TabPanel will be my main navigation and the Toolbar will provide several content-related operations, such as creating a new homework or sth like that.
Here is my "solution", that crtly doesn't work. The TabPanel appears, and the "Hello World" do so, too, but there won't be any Toolbar.
var tapHandler = function(btn, evt) {
alert("Button "+btn.text+" tapped");
}
var HomeScreen = new Ext.Panel({
fullscreen: true,
dockedItems: [
{
xtype: "toolbar",
title: "buttons",
ui: "light",
dock: "bottom",
items: [
{ui: "action", text: "Add"}
],
defaults: {
handler: tapHandler
}
}
],
html: "Hello World"
});
new Ext.Application({
name: "Hello World",
launch: function() {
var tabPanel = new Ext.TabPanel({
fullscreen: true,
ui: 'dark',
sortable: true,
items: [
{
title: "Home",
html: "Loading..."
}
]
});
tabPanel.items.get(0).update(HomeScreen, true);
}
});
Do you have any solutions?
Greetings,
Martin

I think the problem here may well be that the update() method expects an HTML string and HomeScreen is an Ext.Panel.
If it were me, I'd be adding HomeScreen to the items collection in tabPanel either by using the variable like this:
items: [
HomePanel
]
Or by defining it inside the items array as an object:
items: [{
xtype: "panel",
html: "Hello world",
dockedItems: [{
// You toolbar definition
}]
}]
Or by using the TabPanel.add() method:
tabPanel.add(HomePanel);

How to implement this custom grid in ExtJS?

I am new to ExtJS. Currently I have grid implemented as shown below.
But I want to show the same information in a different way like showing in boxes, as shown below. How do I implement this?

You haven't specified which version of Ext JS you are using. So, will give you solution for both versions:
In ExtJS 3.x
You can make use of the Ext.DataView class. Here is an example of dataview. Even though the example makes use of the images, you can easily modify the view, but changing the template. Now, you have to work on the pagination bar. You will have to make use of the bbar property and create a toolbar. This toolbar will have your navigation buttons. So, you will have something like this:
var panel = new Ext.Panel({
id:'person-view',
frame:true,
title:'User Grid',
bbar: [{
text: Prev,
iconCls: 'prev-icon'
},{
text: Next,
iconCls: 'next-icon'
}],
items: new Ext.DataView({
store: yourStore,
tpl: yourTemplate,
autoHeight:true,
multiSelect: false,
overClass:'x-view-over',
itemSelector:'div.thumb-wrap',
emptyText: 'No users to display',
})
});
[Obviously, the above code is not complete. You will have to add your store, template, other properties and event listeners according to user needs.]
In ExtJS 4.x
You will have to make use of Ext.view.View class. Here is a skeleton code:
Ext.define('MyApp.view.members.Display',{
extend: 'Ext.panel.Panel',
alias : 'widget.memberslist',
initComponent: function() {
this.template = Ext.create('Ext.XTemplate',
'<tpl for=".">',
'<div class="member">',
'Name : {name} <br/>',
'Title : {title}',
'</div>',
'</tpl>'
);
this.store = Ext.create('MyApp.store.Members');
this.bbar = this.buildToolbar();
this.items = this.buildItems();
this.callParent(arguments);
},
buildItems: function() {
return [{
xtype: 'dataview',
store: this.store,
id: 'members',
tpl: this.template,
itemSelector: 'div.member',
overItemCls : 'member-hover',
emptyText: 'No data available!'
}]
},
buildToolbar : function() {
return [{
text: 'Previous',
action: 'prev'
},{
text: 'Next',
action: "next"
}];
}
});
The above code makes use of the new MVC architecture. You will have to add the event listeners etc in your controller.

Sencha Touch List Component Inside Tabbed Toolbar

I am working with the Sencha touch framework and there list item component. I have only been working with this for about 2 weeks now and I can not figure out how to get the "onItemDisclosure" to open up the "detailPanel". I am trying to follow this example: http://vimeo.com/19245335. I have pasted my code below. Any help is very much appreciated.
GoW3Guide.views.detailPanel = Ext.extend(Ext.Panel, {
id: 'detailpanel',
tpl: 'Hello, {firstName}!',
dockedItems: [
{
xtype: 'toolbar',
items: [{
text: 'back',
ui: 'back',
handler: function() {
GoW3Guide.Viewport.setActiveItem('disclosurelist', {type:'slide', direction:'right'});
}
}]
}
]
});
Ext.reg('detailPanel', GoW3Guide.views.detailPanel);
GoW3Guide.views.listPanel = Ext.extend(Ext.List, {
id: 'disclosurelist',
store: GoW3Guide.ListStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: true,
onItemDisclosure: function(record, btn, index) {
GoW3Guide.views.detailPanel.update(record.data);
GoW3Guide.views.Guidescard.setActiveItem('detailpanel');
}
});
Ext.reg('listPanel', GoW3Guide.views.listPanel);
GoW3Guide.views.Guidescard = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
initComponent: function() {
Ext.apply(this, {
items: [GoW3Guide.views.listPanel, GoW3Guide.views.detailPanel]
});
GoW3Guide.views.Guidescard.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('guidescard', GoW3Guide.views.Guidescard);

Are you getting any javascript errors?
According to the docs setActiveItem either needs a component instance, a number (card index), or a config object, e.g. {xtype:'detailPanel'}
If you want to make a new detail panel active try
GoW3Guide.views.Guidescard.setActiveItem({xtype:'detailpanel'});
or
GoW3Guide.views.Guidescard.setActiveItem(new GoW3Guide.views.detailPanel());
