I'm quite new to using Sencha Touch. I'm creating an app that has a sidebar and a map pane and when the user clicks on the Show Map button in the sidebar area the map is supposed to center on that location. Where I'm having an issue is that I'm unsure of how to access the {lat} and {lon} properties that are in the tpl variable from the handler function. My apologies if this is a trivial question, but it has me stumped.
Ext.define('Admin.view.Details',
{
extend: 'Ext.Panel',
xtype: 'details',
config:
{
styleHtmlContent: true,
scrollable: 'vertical',
title: 'Individual',
tpl:
[
'Account Number: {comid}',
'<br />',
'Address: ',
'{address} <br />',
'{lat},{lon}',
],
items:
[
{
title: 'Utilities',
items:
[
{
xtype: 'selectfield',
label: 'Utility Type',
options:
[
{text: 'Electricity', value: 'U1'},
{text: 'Water', value: 'U2'},
{text: 'Gas', value: 'u3' },
],
id: 'utilityType',
},
{
xtype: 'selectfield',
label: 'Coverage Area',
options:
[
{text: 'Subdivision', value: 'a1'},
{text: 'Zipcode', value: 'a2'},
{text: 'County', value: 'a3' },
],
id: 'areaType',
},
{
xtype: 'button',
text: 'Show Map',
ui: 'round',
padding:3,
margin:10,
id: 'mapsBTN',
handler: function() {
olMap.setCenter(new OpenLayers.LonLat(lon, lat).transform
(
new OpenLayers.Projection("EPSG:4326"),
olMap.getProjectionObject()
), 16);
}
},
]
},
]
}
});
You need to either implement de handler in your view's controller by adding references to your view and your button and then add a listener for the itemtap event of the button OR implement it in the constructor method of the view :
Ext.define('Admin.view.Details',{
extend: 'Ext.Panel',
xtype: 'details',
config:{
...
},
constructor: function() {
this.callParent(arguments);
var me = this;
this.child('#mapsBTN').setHandler(function() {
me.getTpl(); // Here's your tpl config object
});
}
});
Hope this helped
You can get any variable inside config object by getter.
this.getTpl(); //returns tpl variable
Also note that this must point out to your Admin.view.Details view.

In another question here on Stack Overflow (this one) I have seen this piece of code:
Ext.define("App.view.leaders.MyViewName", {
extend: 'App.view.basePopup',
xtype: 'MyViewName',
config: <Ext.form.IPanel>{
scrollable: 'vertical',
items: [
{
xtype: 'fieldset',
title: 'Add New Auto Asset',
instructions: '<hr class="separate" />',
items: [
<Ext.field.ISelect>{
xtype: 'selectfield',
label: 'Borrower Position',
store: 'BorrowerPositionSelectorStore',
},
<Ext.field.ISelect>{
xtype: 'selectfield',
label: 'Asset Type',
store: 'AssetTypeSelectorStore',
},
{
xtype: 'textfield',
name: '',
label: 'Description'
},
{
xtype: 'numberfield',
name: '',
label: 'Value'
}
]
}
]
}
});
What is the purpose of the <Ext.form.IPanel>, <Ext.form.ISelect> tags before the components definitions? Can you point me to any documentation on that?
It's a TypeScript construct for generics, see: http://www.typescriptlang.org/Handbook
To indicate the type of the object literal, they use:
var square = <Square>{};
My question s in relation to the possible answer in this post Sencha Touch 2 - How to get form values?
Im having the same issue trying to retrieve the values from a form in a View using a Controller.
My current error is Uncaught TypeError: Object # has no method 'getValues'
View:
Ext.define("App.view.Login", {
extend: 'Ext.form.Panel',
requires: [
'Ext.field.Password'
],
id: 'loginview',
config: {
items: [{
xtype: 'titlebar',
title: 'Login',
docked: 'top'
},
{
xtype: 'fieldset',
id: 'loginForm',
defaults: {
required: true
},
items: [{
items: [{
xtype: 'textfield',
name: 'username',
label: 'Username:'
},
{
xtype: 'passwordfield',
name: 'password',
label: 'Password:'
}]
}]
},
{
xtype: 'toolbar',
layout: {
pack: 'center'
}, // layout
ui: 'plain',
items: [{
xtype: 'button',
text: 'Register',
id: 'register',
ui: 'action',
}, {
xtype: 'button',
text: 'Login',
id: 'login',
ui: 'confirm',
}] // items (toolbar)
}]
}
});
Controller:
Ext.define('App.controller.Login', {
extend: 'Ext.app.Controller',
requires: [
'App.view.Login',
'Ext.MessageBox'
],
config: {
refs: {
loginForm: '#loginForm',
register: '#register',
login: '#login'
},
control: {
register: {
tap: 'loadRegisterView'
},
login: {
tap: 'loginUser'
}
},
history: null
},
loadRegisterView: function(btn, evt) {
/*var firststep = Ext.create('App.view.Register');
Ext.Viewport.setActiveItem(firststep);*/
},
loginUser: function(btn, evt) {
var values = loginForm.getValues();
console.log(values);
}
});
Thanks
Edit:
So the below code works but its not how i see everyone doing it.
var form = Ext.getCmp('loginview');
console.log(form.getValues());
Everyone else does this.getLoginView().getValues(); . I dont understand "this" is in the wrong scope and where would getLoginView even be declared? No one ever includes this information in their snippets. Here is another example Sencha Touch 2 - How to get form values?
Add xtype in view below the "id":
xtype: 'loginform',
and then replace the reference of loginForm with this:
loginForm: 'loginform',
Your code will work. The mistake you were doing is you were trying to access the method of 'formpanel' in 'fieldset'.
I have a window with a checkboxGroup in it. I would like whatever selections are made in the checkboxGroup to be saved when my "apply" button on the window is pressed. So far I have
xtype: 'checkboxgroup',
stateful: true,
stateID: 'checks',
getState: function() {
return {
items: this.items
};
},
stateEvents: ['close'],
columns: 2,
vertical: false,
items: [...]
I'm pretty sure my stateEvents are wrong, what would I use to indicate that I want the state to be saved when the parent window is closed?
I have this line in my app.js file's launch function, right before I create the top viewport
Ext.state.Manager.setProvider(Ext.create('Ext.state.CookieProvider'));
Thank you!
apparently the state of the checkbox group does not include the values of the checkboxes http://docs.sencha.com/ext-js/4-0/#!/api/Ext.form.CheckboxGroup-method-getState
i had to go via a session variable and the parent window events ..

I'm trying to learn how to use Sencha Touch to build web apps. I've been following the tutorial Here and I am a bit stuck. Below have created one controller, two views and a model (All other code is copy & paste from the tutorial). The first view, Index works great. However if I try to access the second, it brings up a blank page, none of the toolbar buttons work and it doesn't fire the alert.
If I do comment out the line this.application.viewport.setActiveItem(this.editGyms);, the alert will fire, but obviously, it doesn't render the page.
I've looked at a couple other tutorials, and they seem to also be using the setActiveItem member to switch views.. Am I missing something, or do I have to somehow deactivate the first view to activate the second or something?
HomeController.js
Ext.regController('Home', {
//Index
index: function()
{
if ( ! this.indexView)
{
this.indexView = this.render({
xtype: 'HomeIndex',
});
}
this.application.viewport.setActiveItem(this.indexView);
},
editGyms: function()
{
if ( ! this.editGyms)
{
this.editGyms = this.render({
xtype: 'EditGymStore',
});
}
this.application.viewport.setActiveItem(this.editGyms);
Ext.Msg.alert('Test', "Edit's index action was called!");
},
});
views/home/HomeIndexView.js
App.views.wodList = new Ext.List({
id: 'WODList',
store: 'WODStore',
disableSelection: true,
fullscreen: true,
itemTpl: '<div class="list-item-title"><b>{title}</b></div>' + '<div class="list-item-narrative">{wod}</div>'
});
App.views.HomeIndex = Ext.extend(Ext.Panel, {
items: [App.views.wodList]
});
Ext.reg('HomeIndex', App.views.HomeIndex);
views/home/EditGymStore.js
App.views.EditGymStore = Ext.extend(Ext.Panel, {
html: 'Edit Gyms Displayed Here',
});
Ext.reg('EditGymStore', App.views.EditGymStore);
models/appModel.js
Ext.regModel('WOD', {
idProperty: 'id',
fields: [
{ name: 'id', type: 'int' },
{ name: 'date', type: 'date', dateFormat: 'c' },
{ name: 'title', type: 'string' },
{ name: 'wod', type: 'string' },
{ name: 'url', type: 'string' }
],
validations: [
{ type: 'presence', field: 'id' },
{ type: 'presence', field: 'title' }
]
});
Ext.regStore('WODStore', {
model: 'WOD',
sorters: [{
property: 'id',
direction: 'DESC'
}],
proxy: {
type: 'localstorage',
id: 'wod-app-localstore'
},
// REMOVE AFTER TESTING!!
data: [
{ id: 1, date: new Date(), title: '110806 - Title1', wod: '<br/><br/>Desc1</br><br/>' },
{ id: 1, date: new Date(), title: '110806 - Title1', wod: '<br/><br/>Desc2</br><br/>' }
]
});
viewport.js with toolbar
App.views.viewport = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
scroll: 'vertical',
styleHtmlContent: true,
style: 'background: #d8e2ef',
dockedItems: [
{
xtype: 'toolbar',

buttonAlign: 'right',
items: [
{
id: 'loginButton',
text: 'Login',
ui: 'action',
handler: function() {
Ext.Msg.alert('Login', "This will allow you to Login!");
}
},
{
xtype: 'spacer'
},
{
xtype: 'button',
iconMask: true,
iconCls: 'refresh',
ui: 'action',
handler: function() {
Ext.Msg.alert('Refresh', "Refresh!");
}
}]
},
],
});
Thanks for the help!!
In HomeController.js your action function (editGyms) is the same name as the variable you're using for your view (this.editGyms) so when it tries to setActiveItem(this.editGyms) its actually passing the controllers action function rather than the results of this.render({...})
Either change the name of the controller action or change the name of the variable you use to hold the view.. like
editGyms: function() {
if ( ! this.editGymView) {
this.editGymView = this.render({
xtype: 'EditGymStore',
});
}
this.application.viewport.setActiveItem(this.editGymView);
Ext.Msg.alert('Test', "Edit's index action was called!");
}
I am colleagues with the guy that wrote the tutorial you are referring to. You should add a comment on that post because I described your problem to him and he said that he knows the solution.
You can just add a link to this page so that you won't need to describe everything again.
Also he will (very) soon publish the 3rd part of that tutorial that will cover some similar things.
I'd be grateful for any help please. I've just started to build my first ever sencha app and am pleased with the results so far, but am now stuck on one thing. I've built a search form and want to be able to display the results on the same page, but this is where I'm stuck. The form works and sends the results using GET, but it doesn't send it to the correct place. I want to show it on the same page (I've built a php file called search.php to handle the results), but it reloads the whole app with the variables in the url.
I've tested all of the code away from the app and it works perfectly so I know the problem isn't with the code, but more with my lack of understanding of Sencha so would be extremely grateful for any help.
Code:
searchForms = new Ext.TabPanel({
fullscreen: true,
title: 'Search',
displayField: 'text',
store: searchForm,
iconCls: 'search',
items: [{
id: 'searchSubmit',
xtype: 'form',
standardSubmit : true,
scroll: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Keywords',
defaults: {
// labelAlign: 'right'
labelWidth: '35%'
},
items: [{
xtype: 'textfield',
name: 'keywords',
id: 'keywords',
placeHolder: 'EG: Music, TV',
autoCapitalize : true,
required: true,
useClearIcon: true
}]
}, {
xtype: 'fieldset',
title: 'Advanced Search',
items: [{
xtype: 'selectfield',
name: 'genre',
id: 'genre',
label: 'Genre',
options: [{
text: 'All',
value: ' '
text: 'Country',
value: '1'
text: 'Sci-Fi',
value: '2'
text: 'Western',
value: '3'
}]
}, {
xtype: 'selectfield',
name: 'media',
id: 'media',
label: 'Media',
options: [{
text: 'All',
value: ' '
text: 'Music',
value: '1'
text: 'TV',
value: '2'
text: 'Movie',
value: '3'
}]
}]
}, {
layout: 'vbox',
defaults: {xtype: 'button', flex: 1, style: 'margin: .5em;'},
items: [{
text: 'Search',
ui: 'confirm',
scope: this,
hasDisabled: false,
handler: function(){
searchForms.submit({
url: 'search.php'
});
}
}, {
text: 'Reset',
ui: 'decline',
handler: function(){
searchForms.reset();
}
}]
}]
}]
});
I've then tried to use this to display the results on the same page, but as I say this just doesn't work. It doesn't call the search.php page at all.
I've made sure all of the files (except the index.js file which is in a js folder) are in the same directory as the index.html file.
I've also tried to load the file in the app seperately by using:
Ext.regModel('mobile', {
fields: [
{name: 'text', type: 'string'}
]
});
var searchForm = new Ext.data.TreeStore({
model: 'mobile',
proxy: {
type: 'ajax',
url: 'search.php?keywords=test',
reader: {
type: 'tree',
root: 'items'
}
}
});
and that works perfectly so I know that all of the php stuff is working and does work with Sencha Touch, but I'm just not sure how to get it to only work when somebody clicks 'search'
I'd be grateful for any help with this as I've spent days searching the web to get this fix, but nothing seems to be working :(

Just update your store with the filter() function. First you have to add the correct filterParam to your store configuration. After this, you can call the filter() function in your search button handler. E.g.
searchForm.filter('keywordParam', searchfield.getValue());
After this, your store will get updated without the page refreshing. You could then use a DataView to show your search results.
