I have a tab panel like this
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.create('Ext.TabPanel', {
items: [
{
title: 'First Tab',
id: 'firstTab'
xclass: 'viewClass'
},
{
title: 'Second Tab',
xclass: ''
}
]});}});
in the xclass component there is the path of a class where is defined the view. In the view should be a button, after tap on it, the view should refresh and show another class, for example the view should be defined by 'viewClass2' and not anymore by 'viewClass'
I'm imaging a function triggered on button tap like this:
function(): {
Ext.getCmp('firstTab').xclass = 'viewClass2';
this.getView().refresh() // but it doesen't exist
}
What can i do to change the view?
You can't dynamically change view type.
You can only remove the view and add other one.
Suppose view:
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.create('Ext.TabPanel', {
id: 'tabId',
items: [
{
title: 'First Tab',
id: 'firstTab'
xclass: 'viewClass'
}
]
});
}
});
And the function in some one button should be:
a = function() {
Ext.getCmp('tabId').remove(Ext.getCmp('firstTab'));
Ext.getCmp('tabId').add({'xclass':'viewClass2'})
}

Currently I have a toolbar with some buttons, here is how I create it :
HTML
<div id="toolbarContainer1" style="direction: rtl"></div>
Javascript
var dataArray= [
new WinJS.UI.Command(null, { id: 'cmdView3', label: 'View3', section: 'primary', type: 'button', icon: 'stop', tooltip: 'View 3', onclick: function () { changeView('view3') } }),
new WinJS.UI.Command(null, { id: 'cmdView2', label: 'View2', section: 'primary', type: 'button', icon: 'stop', tooltip: 'View 2', onclick: function () { changeView('view2') } }),
new WinJS.UI.Command(null, { id: 'cmdView1', label: 'View1', section: 'primary', type: 'button', icon: 'stop', tooltip: 'View 1', onclick: function () { changeView('view1') } })
];
window.createImperativeToolBar = function () {
var tb = new WinJS.UI.ToolBar(document.querySelector("#toolbarContainer1"), {
data: new WinJS.Binding.List(dataArray)
});
var thisToolbar = document.querySelector('#toolbarContainer1');
thisToolbar.winControl.closedDisplayMode = 'full';
}
I've tried doing adding it like so :
new WinJS.UI.Flyout(null, { id: 'formatTextFlyout', section: 'primary' })
It gets appended to the DOM but it looks like the options aren't working. The div (flyout) in the dom has no id as I've set above.
I want to show the flyout on button click :
function showFlyout() {
console.log('flyout');
var formatTextButton = document.getElementById("formatTextButton");
document.getElementById("formatTextFlyout").winControl.show(formatTextButton);
}
But obviously because the ID doesn't get set, an error gets logged. Any ideas ?
Here is a fiddle of what I have tried : https://jsfiddle.net/reko91/yg0rs4xc/1/
When you create a win-control like so:
new WinJS.UI.Flyout(null, { id: 'formatTextFlyout', section: 'primary' })
The id "formatTextFlyout" is only the the id of this flyout control.
But you use document.getElementById("formatTextFlyout") method to find this control, the problem is here, this method can only find the html element object with the Id "formatTextFlyout", and there is no one. You can refer to getElementById method.
One solution here is you create a Flyout like so:
HTML:
<div id="flyoutContainer"></div>
Javascript:
var flyout = new WinJS.UI.Flyout(document.querySelector("#flyoutContainer"), { id: 'formatTextFlyout', section: 'primary' });
function showFlyout() {
console.log('flyout');
var formatTextButton = document.getElementById("formatTextButton");
document.getElementById("flyoutContainer").winControl.show(formatTextButton);
}
Or
var flyout = new WinJS.UI.Flyout(document.querySelector("#flyoutContainer"), { id: 'formatTextFlyout', section: 'primary' });
function showFlyout() {
console.log('flyout');
var formatTextButton = document.getElementById("formatTextButton");
flyout.show(selectedButton);
}
If you read the sample of WinJS.UI.Flyout object there, you will find in html file, it creates a Flyout like so:
<div id="formatTextFlyout" data-win-control="WinJS.UI.Flyout"
aria-label="{Format text flyout}">
The html element is div and has a id "formatTextFlyout".
Addition: In the website Try WinJS, there are a lot of win-control samples which written with html+javascript+css.
I have a test application with a couple of views. I am trying to invoke a simple 'tap' listener on my buttons. Even though the controller is instantiated and launched, the tap event does not seem to fire.
Here's my app.js
Ext.application({
name: 'MyApp',
requires: [
'Ext.MessageBox',
'Ext.form.FormPanel',
'Ext.navigation.View'
],
views: [
'Main',

launch: function() {
// Destroy the #appLoadingIndicator element
try{
Ext.fly('appLoadingIndicator').destroy();
}catch(err){
console.warn("[CUSTOMWARN]Could not destroy loading indicator because of -- \n"+err);
}
var DEBUG=false;
if(!DEBUG){
// Initialize the main view
Ext.Viewport.add(Ext.create('MyApp.view.Main'));
}
}
});
Main.js -- controller
Ext.define('MyApp.controller.Main', {
extend: 'Ext.app.Controller',
requires: [
'MyApp.view.Main'
],
init: function(){
// download and parse data from server here.
console.log('controller initiated!');
},
config: {
refs: {
loginBtn: 'button[action=login]'
},
control: {
loginBtn: {
tap: 'loginBtnHandler'
}
}
},
loginBtnHandler: function(){
this.callParent(arguments);
Ext.Msg.alert('here');
}
});
Main.js -- view
Ext.define('MyApp.view.Main', {
extend: 'Ext.navigation.View',
alias: 'customnavigationview',
requires: [
'MyApp.form.Login'
],
config: {
navigationBar: {
hidden: true
},
items: [
{
xtype: 'logincard',
flex: 1
}
],
}
});
Login.js -- for xtype: 'logincard'
Ext.define('MyApp.form.Login', {
extend: 'Ext.form.Panel',
xtype: 'logincard',
requires: [
'Ext.field.Password',
'Ext.field.Email',
'Ext.form.FieldSet',
'Ext.field.Toggle',
'Ext.Label'
],
// id: 'loginForm',
config: {
items: [
{
xtype : 'label',
html : 'Login failed. Please enter correct credentials.',
itemId : 'signInFailedLabel',
hidden : true,

xtype: 'fieldset',
items:[
{
xtype: 'textfield',

label: 'UserName'
},
{
xtype: 'passwordfield',

label: 'Password'
}
]
},
{
xtype: 'fieldset',
items: [
{
xtype : 'togglefield',

xtype : 'button',
id : 'loginSubmitBtn',
itemId : 'loginSubmitItemBtn',
text : 'Login',
ui : 'action',
action : 'login',
margin : 10
}
]
}
});
Any help would be highly appreciated!
EDIT: So I tried to use Ext.ComponentQuery.query("#loginSubmitBtn") and on printing the output on console, I can see that it is pointing to the correct button. Here's the output.

**EDIT 3: ** Found it! See answer here: Sencha Tap listener not firing
The listener for a button tap should be just 'tap' instead of 'itemtap'
tap: 'loginBtnHandler'
Hope it helps-
I think I've had this problem in the past. Try qualifying the ref in the controller with the view name to narrow the query down:
loginBtn: 'logincard button[action=login]'
Not the best, but should work:
First remove the tap listener on the controller. Also remove the 'action' property on the button, and set the handler on the button:
{
xtype : 'button',
id : 'loginSubmitBtn',
itemId : 'loginSubmitItemBtn',
text : 'Login',
ui : 'action',
//action : 'login',
margin : 10,
handler : function () {
MyApp.app.getController('Main').loginBtnHandler()
}
}
Ok, this is weird, but I found out why my buttonclick was not being handled properly. I usually use Google Chrome as my testing browser with web inspector on. I downloaded Safari and tried the same code and it worked like its supposed to. I looked at both the browsers, and the only difference was that Chrome had web inspector on, while Safari didn't. I closed the web inspector in Chrome and the button handler worked great (without reloading). I restarted the browser, pushed the inspector to a separate window, none of them worked. However, Safari works great even with inspector on. Probably a Chrome bug?
Google Chrome version: 27.0.1453.110
*EDIT: * I had the touch emulation turned on in the web inspector. With this turned on, we have to close the web inspector for the touch event to register. Otherwise, we have to turn off the touch emulation to register for the events while the web inspector is open.
TL;DR: Close your web inspector in Chrome before testing, if you have touch emulation turned on.
Hi I have the code below my my enter event is never triggering, any help will be appreciated.
items: [{
xtype: 'textfield',
id: 'idhere',
name: 'namehere',
fieldLabel: 'lablehere:',
width: 500,
handler: {
key:13,
fn : function () {
if (e.getKey() == e.ENTER) {
alert("You pressed an enter button in text field.");
}
}
}
},{
xtype: 'button',
text: 'texttodisplay',
handler: function() {
//my function.
}
}]
I actually solved this by using:
listeners: {
specialkey: function (f,e) {
if (e.getKey() == e.ENTER) {
loadData();
}
}
}
I am not sure why Sencha never included Ext.ux.form.SearchField in the API docs but the component has been included in all versions of the framework I've used. It is set-up to fire a submit and a cancel event and includes the appropriate search and cancel buttons attached to the field.
You can find it in your framework files at: [extjs-root]\examples\ux\form\SearchField.js
I would recommend using that component instead of trying to create your own searchfield. I usually override the default search function to fit my own needs but there have been a few scenarios where I did not need to also.
If you add a requires statement at the top of your component JS you can create it like any other (non-UX) component:
E.g:
Requires statement:
Ext.define('MyApp.view.SomeComponent', {
extend: 'Ext.grid.Panel',
alias: 'widget.mycomponent',
requires: [
'Ext.ux.form.SearchField'
],
...
Creating a search field in the panel's bottom toolbar:
bbar: {
items: [{
text: 'A Button'
}, {
text: 'Another Button'
}, '-', {
xtype: 'searchfield', // <- can use this xtype with requires stmt
itemId: 'search',
width: 250,
emptyText: 'Enter first and last name to search...'
}]
},
...
If you have trouble with the requires statement you could also just create it like this:
var search = Ext.create('Ext.ux.form.SearchField', {
itemId: 'search',
width: 250,
emptyText: 'Enter first and last name to search...'
});
Just to supply how to add such a listener. There is a specialkey event that can be used for such a case
fieldinstance.on('specialkey', function(f, e){
if (e.getKey() == e.ENTER) {
// your action
}
});
Anyway I recommend to use the ux component that #Geronimo mentioned
Im learning Extjs and have a problem , when i try to append new text to an item i get an error tf.setValue is not a function same goes for getValue. When i try setVisible it works like it should be.
Ext.Loader.setConfig({enabled:true});
Ext.application({
name: 'app',
controllers:[
],
appFolder: 'app',
launch: function() {
var panel = new Ext.form.FormPanel({
renderTo:Ext.getBody(),
title:'Panel',
width:400,
bodyPadding: 10,
autoHeight:true,
items:[{
xtype:'textareafield',
name: 'textInput',
id:'textId',
value:'why not'
},{
xtype:'button',
text:'Helllo',
handler:function(){
console.log('button click')
var tf = Ext.get('textId');
tf.setValue('This should change!')
}
}],
});
}
});
Thanks
That's because Ext.get() will return an Ext.Element.
What you want to use is Ext.getCmp('textId') which will return the component.
The Element is basically the Ext wrapper round the Dom element, so it has methods like setVisible, but you want to get the text area component, which has all the methods you're after.
I'am trying to build my first little Sencha Touch 2 app. I've created some stuff that is working as expected and now I could like to create some event handling stuff.
I've created the following store:
Ext.define('Mobile.store.Blogs', {
extend: 'Ext.data.Store',
config: {
},
listeners: {
'load' : function(store,records,options) {
store.loaded = true;
console.log("fired blogCountAvailable");
store.fireEvent("blogCountAvailable");
},
'blogCountAvailable': function(store, records, options) {
console.log("blogCountAvailable has been fired");
}
}
});
This stuff works as expected, but now comes the next step.
Here is the code of my tab panel bar:
Ext.create("Ext.tab.Panel", {
xtype:'mainTabPanelBottom',
tabBarPosition: 'bottom',
fullscreen: true,
items: [
{
title: 'Blog',
iconCls: 'home',
xtype:'mainpanel'
},
{
title: 'Users',
iconCls: 'user',
xtype:'userpanel'
}
],
listeners: {
blogCountAvailable: function(tabpanel, newTab) {
var tab = newTab.tab,
badge = 10;
tab.setBadge(badge);
console.log("blogCountAvailable has been fired");
}
}
});
My question now is how I could achieve it to "fire" my custom event blogCountAvailable to the tab panel?
The easiest way is just set an id for your TabPanel and then:
Ext.getCmp('your_TabPanel_id').fireEvent("blogCountAvailable");
