In view,
{
xtype: 'textfield',
fieldLabel: 'Test Field',
name: 'testField'
}
I want to grep that textfield in controller to hook Keyup event.
I tried,
this.control({
'input[name='testfield']' : {
afterrender : function(c){
console.log(c); // nothing happened.
c.getEl().on('keyup', function (evt, el) {
console.log(evt.getKey());
});
}
}
});
but it does not work,
How can I grep that textbox in controller and hook keyup event?
Anybody know, please advise me.
Thanks
it should be
this.control({
'textfield[name='testfield']' : {
afterrender : function(c){
console.log(c); // nothing happened.
c.getEl().on('keyup', function (evt, el) {
console.log(evt.getKey());
});
}
}
});
you've specified input instead of textfield.
The selectors that you specify in the this.control function should conform to those accepted by Ext.ComponentQuery. Check documentation

I am new to Sencha Touch2 and facing problem while passing data from my Controller to Floating panel on listitem tap. Here is my controller implementation code:
Ext.define('CustomList.controller.Main', {
extend: 'Ext.app.Controller',
requires:['CustomList.view.DatePanel'],
config: {
refs: {
listView: 'listitems'
},
control: {
'main test2 list': {
activate: 'onActivate',
itemtap: 'onItemTap'
}
}
},
onActivate: function() {
console.log('Main container is active');
},
onItemTap: function(view, index, target, record, event) {
console.log('Item was tapped on the Data View');
Ext.Viewport.add({
xtype: 'DatePanel'
});
}
});
Am able to get data in the controller and DatePanel.js is my floating Panel.
DatePanel.js:
Ext.define('CustomList.view.DatePanel', {
extend: 'Ext.Panel',
alias: 'widget.DatePanel',
xtype:'datepanel',
config: {
itemid:'DatePanel',
modal:true,
centered: true,
hideOnMaskTap:true,
width:'500px',
height:'650px',
items:[
{
styleHtmlCls:'homepage',
tpl:'<h4>{name3}</h4>'
},
{
xtype:'toolbar',
docked:'bottom',
items:[{
text:'OK',
ui:'confirm',
action:'ShowTurnOverReport',
listeners : {
tap : function() {
console.log('Ok');
}
}
},
{
text:'Cancel',
ui:'confirm',
action:'Cancel',
listeners : {
tap : function() {
console.log('Cancel');
var panelToDestroy = Ext.getCmp('datepanel');
panelToDestroy.destroy();
Ext.Viewport.add(Ext.create('CustomList.view.Test2'));//Test.js is my list Panel
}
}
}]
}
]
}
});
Help me out in destroying the panel on 'Cancel' Button.
Can anyone please help me. Thanks.
Create instance of panel you want to add first.
var floatingDatePanel = Ext.create('Yourapp.view.YourDatePanel');
Next get data of selected list item on itemTap
var data = record.getData();
Assign this data to floatingDatePanel with setData() method
UPDATE,
after looking at your panel code, I guess you want to set data to first item in panel ie
{
styleHtmlCls:'homepage',
tpl:'<h4>{name3}</h4>'
}
Right ? If so then you need to change following code
floatingDatePanel.setData(data);
to
floatingDatePanel.getAt(0).setData(data);
Because, it is first item inside panel that is having a template assigned and hopefully the same where you want to set data.
then finally, you can add this panel into viewport with
Ext.Viewport.add(floatingDatePanel);
I have this defined in my view:
View:
Ext.define("MyApp.view.Welcome", {
extend: 'Ext.Panel',
alias: 'widget.welcomeview',
config: {
///...items... removed lines for brevity..
{
xtype: 'button',
id : 'btnSignInNow',
text: 'Sign In Now',
listeners: {
tap: function() {
this.fireEvent("onSignInNowTap", this);
console.log("onSignInNowTap fired"); /// <-- I see this in console.log
}
}
}
I can see this in the log. But in my controller it is not receiving the event. Can anybody shed any light on this?
Controller:
config: {
refs: {
welcomeView: 'welcomeview'
},
control: {
welcomeView: {
onSignInNowTap: function () {
alert('bla!'); <!-- I Don't see this in console.log
}
}
}
}
I appreciate I might have missed something, but is there any way that I can debug to find out how/where this event is being lost or ignored?
Try
this.parent.fireEvent("onSignInNowTap", this);
instead of
this.fireEvent("onSignInNowTap", this);
that way parent view will be firing event instead of button.
Sometimes if button is nested deep inside you might have to do something like this
this.parent.parent.parent....fireEvent("onSignInNowTap", this);
Write your view's listeners inside initialize,
you will get reference to this in the initialize
Ext.define("MyApp.view.Welcome", {
extend: 'Ext.Panel',
alias: 'widget.welcomeview',
initialize:function(){
this.callParent();
listeners: {
tap: function() {
this.fireEvent("onSignInNowTap", this);
console.log("onSignInNowTap fired");
}
}
}
Thanks ThinkFloyd. Your solution worked. I had to to use this.parent.fireEvent(...) and then the controller was able to catch it...
I am trying to respond to a view-fired event inside a controller. The event does fire, but the controller action is never called.
View:
Ext.define("MyApp.view.Dashboard", {
extend: 'Ext.Container',
xtype: 'my_dashboard',
config: {
items: [
{
xtype: 'dataview',
listeners: {
itemtap: function(sender, index, elem, record) {
// fires with param, e.g. 'inbox'
this.fireEvent(record.get('name'));
}
}
}
...
Controller:
Ext.define('MyApp.controller.Dashboard', {
extend: 'Ext.app.Controller',
config: {
control: {
'my_dashboard': {
'inbox': 'showInbox',
...
}
}
},
showInbox: function () {
/* never gets called */
},
...
What am I doing wrong?
UPDATE:
I found a solution, but it feels very hacky. I added a bubbleEvents config to the dataview and the my_dashboard view, and the events started making their way up to the controller.
Since the dashboard can have a variable number of items, I don't know which events I need to bubble up. Of course, I could bubble up all possible dashboard events, but that just seems like a massive kludge.
Should the view fire an application event instead, e.g. MyApp.app.fireEvent()?
I would put an itemId on the dataview.
itemId: 'my_dashboard_dataview'
Then in your controller...
control: {
'#my_dashboard_dataview': {
'itemtap': 'showInbox',
...
}
}
UPDATE
Here is some code that should get you started:
Controller:
Ext.define('MyApp.controller.Dashboard', {
extend: 'Ext.app.Controller',
config: {
control: {
'my_dashboard': {
painted: 'onDashboardPainted',
inbox: 'showInbox'
}
}
},
onDashboardPainted: function(dashboard, eOpts) {
dashboard.down('dataview').on('itemtap', function(sender, index, elem, record){
dashboard.fireEvent(record.get('name'));
//check the console to make sure you the value is: inbox
console.log(record.get('name'));
});
},
showInbox: function () {
console.log('showInbox init');
},
This is definately a scope issue... in your controller add a painted function for my_dashboard... the first function variable will be the my_dashboard component itself:
painted: function(dashboard,...
Now in the painted function add the listener dynamically:
dashboard.down('dataview').on( ... rest of listener code ...
Now inside of the listener do dashboard.fireEvent(....);
Sorry for the formatting im on my mobile, if u cant get it to work i will post code tomorrow
I'm just getting started with Sencha Touch 2 and I have never worked with Sencha Touch 1.x before. I've just finished this tutorial (which is the best starter tutorial I have found so far) http://miamicoder.com/2012/how-to-create-a-sencha-touch-2-app-part-1/ and now I want to go ahead and extend this Notes App.
I have a controller and 2 views, a list view and an edit view. In the edit view I want to be able to delete the current record. The delete function is in the controller. After tapping the delete button, I want to show a confirmation dialog ("Are you sure you want to delete...?"). After the user presses yes, the delete function should be called.
Now my problem is: How do I call the controllers delete function from within Ext.Msg.confirm?
Here are the relevant snippets of my code. Please let me know if something important is missing.
Please see the "onDeleteNoteCommand" function. "this.someFunction" obviously doesn't work since "this" is a DOMWindow.
Ext.define('TestApp2.controller.Main', {
extend: 'Ext.app.Controller',
config: {
refs: {
noteEditorView: 'noteeditorview'
},
control: {
noteEditorView: {
deleteNoteCommand: 'onDeleteNoteCommand',
}
}
},
onDeleteNoteCommand: function() {
console.log('onDeleteNoteCommand');
var noteEditor = this.getNoteEditorView();
var currentNote = noteEditor.getRecord();
Ext.Msg.confirm(
"Delete note?",
"Do you reall want to delete the note <i>"+currentNote.data.title+"</i>?",
function(buttonId) {
if(buttonId === 'yes') {
//controller functions!! how to call them?
this.deleteNote(currentNote);
this.activateNotesList();
}
}
);
},
deleteNote: function(record) {
var notesStore = Ext.getStore('Notes');
notesStore.remove(record);
notesStore.sync();
},
activateNotesList: function() {
Ext.Viewport.animateActiveItem(this.getNotesListView(), this.slideRightTransition);
},
slideLeftTransition: { type: 'slide', direction: 'left' },
slideRightTransition: { type: 'slide', direction: 'right' },
launch: function() {
this.callParent();
Ext.getStore('Notes').load();
console.log('launch main controller');
},
init: function() {
this.callParent();
console.log('init main controller');
}
});
When you enter callback function of Ext.Msg the scope changes from controller scope to global scope (window), so you must set up it as parameter of confirm method:
Ext.Msg.confirm(
"Delete note?",
"Do you reall want to delete the note <i>"+currentNote.data.title+"</i>?",
function(buttonId) {
if(buttonId === 'yes') {
this.deleteNote(currentNote);
this.activateNotesList();
}
},
this // scope of the controller
);

I have a FormPanel (Ext.form.Panel) with text fields; I'd like the text fields to automatically resize so that their entire contents are visible, but the following isn't working:
Ext.define('myapp.view.admin.EditUserFormPanel', {
extend: 'Ext.form.Panel',
initComponent: function() {
var me = this;
me.items = [
{
xtype: 'textfield',
fieldLabel: 'OpenID',
name: 'openid',
grow: true,
listeners: {
autosize: function(newWidth) {
console.log(newWidth);
},
focus: function(txtField) {
console.log('focus fired');
txtField.autoSize();
}
}
}
];
me.callParent();
}
});
Both of my event handlers fire. However, autosize only fires when the form is rendered; not when I try to manually call autoSize().
Any ideas?
Changing the layout to something other than the default 'anchor' solved the problem. Example:
