Why isn't this listener being triggered - extjs4

I have the following view I have defined:
Ext.define("app.view.stock.SearchValueField", {
extend: "Ext.form.field.Text",
alias: "widget.searchvaluefield",
name: "search_value_field",
enableKeyEvents: true,
allowBlank: false,
listeners: [
{
keyup: {
fn: function(){console.log('logged');}
}
}
],
initComponent: function() {
this.callParent(arguments);
}
});
But on keyup the listener isn't being triggered. I am quite well versed in the mvc architecture so please assume that the other parts of my app are correct.

You have to provide an Object for the listeners config parameter, as described in the Observable documentation.
You used an Array. It works using the following code:
Ext.define("app.view.stock.SearchValueField", {
extend: "Ext.form.field.Text",
alias: "widget.searchvaluefield",
name: "search_value_field",
enableKeyEvents: true,
allowBlank: false,
listeners: {
keyup: function() {
console.log('logged');
},
},
// actually the 'empty' override of initComponent isn't necessary
initComponent: function() {
this.callParent(arguments);
}
});

How to pass argument in Controller file using function in sencha touch

I have created one sencha touch application in my localserver.
In that application, there are one textfield, and three buttons.
The following is my app.js file
Ext.application({
name: 'MyApp',
requires: [
'Ext.MessageBox'
],
views: [
'Main'
],
controllers: [
'CalcController'
],
icon: {
'57': 'resources/icons/Icon.png',
'72': 'resources/icons/Icon~ipad.png',
'114': 'resources/icons/Icon#2x.png',
'144': 'resources/icons/Icon~ipad#2x.png'
},
isIconPrecomposed: true,
startupImage: {
'320x460': 'resources/startup/320x460.jpg',
'640x920': 'resources/startup/640x920.png',
'768x1004': 'resources/startup/768x1004.png',
'748x1024': 'resources/startup/748x1024.png',
'1536x2008': 'resources/startup/1536x2008.png',
'1496x2048': 'resources/startup/1496x2048.png'
},
launch: function() {
// Destroy the #appLoadingIndicator element
Ext.fly('appLoadingIndicator').destroy();
// Initialize the main view
Ext.Viewport.add(Ext.create('MyApp.view.Main'));
},
onUpdated: function() {
Ext.Msg.confirm(
"Application Update",
"This application has just successfully been updated to the latest version. Reload now?",
function(buttonId) {
if (buttonId === 'yes') {
window.location.reload();
}
}
);
}
});
The following is my Main.js file
Ext.define('MyApp.view.Main', {
extend: 'Ext.form.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.Video'
],
config: {
items: [
{
xtype:'textfield',
name:'txtDisplay',
id:'idDisplay',
readOnly:true,
},
{
xtype:'button',
name:'btnClear',
id:'idClear',
width:'25%',
text:'C',
style:'float:left;',
},
{
xtype:'button',
name:'btnSeven',
id:'idSeven',
width:'25%',
text:'7',
style:'float:left; clear:both;',
//action:
handler: function()
{
var x = Ext.getCmp('idSeven')._text;
Ext.getCmp('idDisplay').setValue(x);
}
},
{
xtype:'button',
name:'btnEight',
id:'idEight',
width:'25%',
text:'8',
style:'float:left;',
action:'displayNum',
}
]
}
});
The following is my CalcController.js file
Ext.define('MyApp.controller.CalcController', {
extend: 'Ext.app.Controller',
config: {
control: {
'button[action=displayNum]' : {
tap: 'displayNum'
},
}
},
displayNum: function()
{
console.log("This click event works");
}
});
Now my question is as following:
When i press button named btnSeven it display digit 7 in textfield means handler function works.
Now i want click event code in CalcController.js file instead of writing handler function in Main.js file for that i created second button named btnEight and give action:'displayNum' so when that button clicked event goes to the CalcController.js file.
When i pressed button named btnEight then i want to display digit 8 in textfield with the help of writing code in CalcController.js file instead of writing hander function in Main.js file. So how to do this?
Instead of defining Id for component , define Item Id
In Controller you have to define references in config.
config: {
refs: {
'idDisplay': 'main #idDisplay' // idDisplay is itemId not Id here
},
control: {
'button[action=displayNum]' : {
tap: 'displayNum'
}
}
},
and in displayNum function write code like this.
displayNum: function(btn)
{
var display = this.getIdDisplay();
display.setValue(btn.getText());
}
I solved above my question as the following method:
Now my Main.js file is as following:
Ext.define('MyApp.view.Main', {
extend: 'Ext.form.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.Video'
],
config: {
items: [
{
xtype:'textfield',
name:'txtDisplay',
id:'idDisplay',
readOnly:true,
},
{
xtype:'button',
name:'btnClear',
id:'idClear',
width:'25%',
text:'C',
style:'float:left;',
action: 'clearDisplay',
},
{
xtype:'button',
name:'btnSeven',
id:'idSeven',
width:'25%',
text:'7',
style:'float:left; clear:both;',
action: 'displayNum',
/*handler: function()
{
var x = Ext.getCmp('idSeven')._text;
Ext.getCmp('idDisplay').setValue(x);
}*/
},
{
xtype:'button',
name:'btnEight',
id:'idEight',
width:'25%',
text:'8',
style:'float:left;',
action:'displayNum',
}
]
}
});
and CalcController.js file is as following:
Ext.define('MyApp.controller.CalcController', {
extend: 'Ext.app.Controller',
config: {
control: {
'button[action=displayNum]' : {
tap: 'displayNum'
},
'button[action=clearDisplay]' : {
tap: 'clearDisplay'
},
}
},
displayNum: function(button, e, eOpts)
{
var x = Ext.getCmp('idDisplay')._value + button._text;
Ext.getCmp('idDisplay').setValue(x);
},
clearDisplay: function(button, e, eOpts)
{
Ext.getCmp('idDisplay').setValue('');
}
});
Using this method i pass my button's properties in the controller file using the button's tap event.

I need to assign extra param "refresh" to true when i refresh the list. On the other hand, if the load more event fire i need to assign param refresh to false. Please give me solution. Thanks
I dont think you can do it the way you ask. But you can listen to the load event and change your refresh parameter there.
{
xtype: 'store',
//Your Code
listeners: {
load: function(store){
store.getProxy.setExtraParam('refresh', false);
}
}
}
Hope it helps

Can anyone help me to how to insert the values in the db.
Javascript is case-sensitive. From Sencha Touch docs:
These getter functions are generated based on the refs you define and
always follow the same format - 'get' followed by the capitalized ref
name.
To use the getter method for ref, loginForm, and to get the form values use:
var values = this.getLoginForm().getValues();

Link item list to Carousel item

I would like to link a list to another view (carousel layout), for example carousel item no. 2.
What should I put in this bracket?
onItemDisclosure: function() {
[......]

I want to achieve something like carousel.setActiveItem(x)
where x is my carousel content.
I have worked on your problem. May be this helps you.

Sencha Touch 2 - switch views

I started to use the Sencha Touch 2 MVC, but I can't overcome the problem below.
I have an Ext.application code:
Ext.application({
name: 'ProjectName',
appFolder: APP_URL + "app",
enableQuickTips: true,
extend: 'Ext.app.Controller',
phoneStartupScreen: 'LOGO.png',
controllers: ['Site'],
views: ['Viewport_login', 'Viewport_reg'],
layout: 'vbox',
launch: function() {
//bootstrap
Ext.create("Ext.Container", {
requires: [
],
items: [
Ext.create("ProjectName.view.Viewport_login", {}),
Ext.create("ProjectName.view.Viewport_reg", {})
]
});
return true;
}
});
view 'Viewport_login' code:
Ext.define('ProjectName.view.Viewport_login', {
extend: 'Ext.Panel',
requires: [
'ProjectName.view.Login',
'ProjectName.view.Header'
],
fullscreen: true,
initialize: function() {
console.log("init viewpor_login");
Ext.create("Ext.Container", {
//fullscreen: true,
style: 'background-color: white;',
layout: 'vbox',
fullscreen: true,
scrollable: true,
items: [
{
xtype: 'Bheader'
},
Ext.create("widget.login")
]
});
this.callParent();
}
});
View 'Viewpoer_reg' code:
Ext.define('ProjectName.view.Viewport_reg', {
extend: 'Ext.Panel',
requires: [
'ProjectName.view.Reg',
'ProjectName.view.Header'
],
fullscreen: true,
initialize: function() {
console.log("init viewpor_reg");
Ext.create("Ext.Container", {
//fullscreen: true,
style: 'background-color: white;',
layout: 'vbox',
fullscreen: true,
scrollable: true,
items: [
{
xtype: 'Bheader'
},
Ext.create("widget.reg")
]
});
this.callParent();
}
});
view 'Header' code:
Ext.define('ProjectName.view.Header', {
extend: 'Ext.Panel',
alias: 'Bheader',
xtype: 'Bheader',
requires: [
'Ext.Img'
],
initialize: function() {
console.log("header inited");
},
config: {
cls: 'bg-holder',
items: [
Ext.create("Ext.Img", {
src: BASE_URL + 'assets/images/header3.png',
height: 35,
width: "100%",
style: "background-position: center 0px; "
})
]
}
});
And finally the 'Site' controller's code:
Ext.define('ProjectName.controller.Site', {
extend: 'Ext.app.Controller',
config: {
views: ['Viewport_login', 'Viewport_reg']
},
init: function() {
console.log('Init site controller');
// Start listening for events on views
this.control({
// example of listening to *all* button taps
'#login_button': {
tap: function () {
// HOW CAN I SWITCH TO 'VIEWPORT_REG' VIEW?
}
}
});
},
renderRegFOrm: function() {
},
onLaunch: function() {
console.log('onLaunch site controller');
},
});
First, I have a problem right now: The 'Header' does'nt appear if I load both views ('Viewport_login', 'Viewport_reg') in Container which created in Ext.application launch function. Can anyone help me, why?
Second, in the Controller code you can see the this.control(... section. How can I switch to other view in here?
From looking at your code, it appears that you only want one of login and register to appear at one time. I would recommend looking at the setActiveItem method for containers and switching views in this way.
I didn't understand your first question. Also, didn't understand why you have widget.login and widget.reg classes when you already have views called login and reg (can't you just use those?)
