How to call JSONP request in Sencha Touch application - sencha-touch

In my sencha application i need to call jsonp request instead of ajax request but i dont know how to write it.So please provide me demo for jsonp request.
thank You

Sample JSON Request from the Sencha Documentation :)
Here's the link to more details : http://docs.sencha.com/touch/2-0/#!/api/Ext.data.JsonP
Ext.data.JsonP.request({
url: 'http://free.worldweatheronline.com/feed/weather.ashx',
callbackKey: 'callback',
params: {
key: '23f6a0ab24185952101705',
q: '94301', // Palo Alto
format: 'json',
num_of_days: 5
},
success: function(result) {
//Your success function here...
}
});

check the below code working fine for me :)
Ext.define('APP.view.List', {
extend: 'Ext.Container',
requires: [
'Ext.data.JsonP'
],
config: {
scrollable: true,
items: [{
xtype: 'panel',
id: 'JSONP'
}, {
docked: 'top',
xtype: 'toolbar',
items: [{
text: 'Load using JSON-P',
handler: function() {
var panel = Ext.getCmp('JSONP'),
tpl = new Ext.XTemplate([
'<div class="demo-weather">',
'<tpl for=".">',
'<div class="day">',
'<div class="date">{date}</div>',
'<tpl for="weatherIconUrl">',
'<img src="{value}">',
'</tpl>',
'<span class="temp">{tempMaxF}°<span class="temp_low">{tempMinF}°</span></span>',
'</div>',
'</tpl>',
'</div>'
]);
panel.getParent().setMasked({
xtype: 'loadmask',
message: 'Loading...'
});
Ext.data.JsonP.request({
url: 'http://free.worldweatheronline.com/feed/weather.ashx',
callbackKey: 'callback',
params: {
key: '23f6a0ab24185952101705',
q: '94301', // Palo Alto
format: 'json',
num_of_days: 5
},
callback: function(success, result) {
var weather = result.data.weather;
if (weather) {
panel.updateHtml(tpl.applyTemplate(weather));
}
else {
alert('There was an error retrieving the weather.');
}
panel.getParent().unmask();
}
});
}
}]
}]
}
});

},
}
}
});
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

sencha-touch: Login request-response

I am very new to sencha-touch & started to build simple Login form.
My UI is ready but now I am stuck on how to write code for login request response.
As important, how can I point to specific url to make POST/GET request?
Also how to get & parse the json data.?
I read the sench-touch documentation but I didnt understood, how to use that model, store, proxy.
Suggestions upon how to create model, store, proxy to make simple login are very helpful.
Thanks in advance.
Edited to insert image:
var loginForm = Ext.create('Ext.form.Panel', {
fullscreen: true,
items: [{
xtype: 'fieldset',
items: [
{
xtype: 'textfield',
name : 'name',
label: 'Username'
},
{
xtype: 'passwordfield',
name : 'password',
label: 'Password'
}
]
}]
});
loginForm.add({
xtype: 'button',
text: 'Login',
ui: 'confirm',
badgeText: '1',
// handler: function(){
// // alert("handler invoked");
// },
listeners : {
tap : function() {
var form = Ext.getCmp('form-id');
var values = form.getValues();
Ext.Ajax.request({
url: 'https://102.XXX.X.XX:XXXX/QuizMasterServer/rest/login',
params: values,
success: function(response){
var text = response.responseText;
Ext.Msg.alert('Success', text);
},
failure : function(response) {
Ext.Msg.alert('Error','Error while submitting the form');
console.log(response.responseText);
}
});
}
}
});
loginForm.add({
xtype: 'toolbar',
// id:'loginPressed',
docked: 'bottom',
// layout: { pack: 'center' },
items: [
{
xtype: 'button',
text: 'Login',
ui: 'confirm',
// action: 'login',
handler: function() {
loginForm.setValues({
name: 'vs',
password: 'vs'
})
}
},
{
xtype: 'button',
text: 'Clear',
ui:'decline',
handler: function() {
loginForm.reset();
}
},
{
xtype: 'button',
centered: true,
text: 'Sign Up',
handler: function() {
alert('New User?');
}
},
{
xtype: 'container',
html: 'New User? ',
style: {
color: 'yellow',
}
},
]
});
Exemplo usando ajax request:
Example using ajax request:
Ext.Ajax.request({
url: domain.com/auth/signIn/',
method: 'post',
scope: this,
params: {
email: username,
password: password
},
success: function (response) {
var result = Ext.JSON.decode(response.responseText);
if (result.meta.code==200)
{
/**
* Salvando dados do usuário em localStorage
* Save user data on localStorage
*/
window.localStorage.setItem('myID', result.response.id);
window.localStorage.setItem('email', result.response.email);
window.localStorage.setItem('token', result.response.token);
window.localStorage.setItem('fName', result.response.fName);
window.localStorage.setItem('lName', result.response.lName);
window.localStorage.setItem('photo', result.response.photo);
window.localStorage.setItem('gender', result.response.gender);
window.localStorage.setItem('relationship', result.response.relationship);
window.localStorage.setItem('interest', result.response.interest);
this.signInSuccess();
this.verifyDeviceToken(result.response.id, 'signin');
}
else
{
this.signInFailure('Error', 'The data reported are invalid');
}
},
failure: function (response) {
}
});
You are almost there!
add your code to the success callback.
Note, success() callback if fired if ajax returns ok, otherwise failure(). Callback callback() fire in both cases.
Ext.Ajax.request({
url: 'https://102.XXX.X.XX:XXXX/QuizMasterServer/rest/login',
params: values,
success: function(response){
var text = response.responseText;
// for example
var result = Ext.decode(text); // json parsing
if (result.ok) {
//create new widget
var homeView = Ext.widget('homePage', {...});
Ext.Viewport.remove(formLogin);
Ext.Viewport.add(homeView);
///... etc
homeView.show()
}
Ext.Msg.alert('Success', text);
},
failure : function(response) {
Ext.Msg.alert('Error','Error while submitting the form');
console.log(response.responseText);
}
});
Disclaimer. Of course the code is not tested...
cheers, Oleg

Sencha Touch Tree Store 'Object has no method getRootNode'

I am developing an Android 2.3.3 app using PhoneGap and Sencha Touch 2 ...
I have an Login view from which i redirect to nested list view in my app ... I used an inline store for the nested list and i defined the type as 'tree' for the store ...
The first time i am trying to load the app and when i click on Login it is giving me an error ... The error is stated below :

I need to get rid of this error as soon as possible ... Everything in my app is working fine from the second time onwards ... I think the problem is with the store i have defined ... Please help me guys ... Thanks in Advance ...!!!
My store is defined inline in my IncidentList View itself ...
store: {
type: 'tree',
fields: ['TKT_ID', 'CREATED_ON', 'FIRST_NAME', 'TKT_STATUS_NAME', 'TKT_SUBJECT', 'TKT_DESC', 'SEV_DESC', 'SERVICE_NAME', 'CATEGORY_NAME', {
name: 'leaf',
defaultValue: true
}],
root: {
leaf: false
},
data : localStorage.userIncidentData,
proxy: {
type: 'memory',
reader: {
type: 'json',
rootProperty: 'incidentList'
}
}
},
This is true: Object [object Object] has no method getRootNode
This method is no longer available in ST2, take a look at the API docs.
Actually, this is the only place in ST code that has this method left. Try editing sencha code in TreeStore
removeAll: function() {
this.getRootNode().removeAll(true);
this.callParent(arguments);
},
to
removeAll: function() {
this.getRoot().removeAll(true);
this.callParent(arguments);
},

how to make visible list in sencha touch2

i am new to sencha touch2. i want display list in a page. binding is happening successful. but i am not able to see data but able to scroll page. please any one can help me. i facing this issue. thank you.
My code is here:
Ext.define("Sencha.view.ProjectListView", {
extend: 'Ext.form.Panel',
xtype: 'projectListepage',
id: 'projectListepage',
requires: [
'Ext.data.JsonP'

text: 'Project Deatils',
handler: function () {
var list = Ext.getCmp('JSONP'),
tpl = new Ext.XTemplate([
'<tpl for=".">',
'<img src="{MainImageUrl}"/><label>{ProjectName}</label><p class="temp_low">{ShortDescription}</p>', //

]);
Ext.data.JsonP.request({

}
else {
alert('There was an error retrieving the weather.');
}
}
});
}
}]
}]
}
});
I do not see anywhere in your code sample where you are creating a list. You need to extend 'Ext.List' or use xtype:'list'. There are a few simple examples in the sencha touch 2 docs on how to create a list. http://docs.sencha.com/touch/2-0/#!/api/Ext.dataview.List

Why isn't my ajax data being loaded into the panel?

So I have this handler which puts my 'statistics' card into view and loads the statistics store (I can see in chrome that an ajax request is sent to the server and the statistics are getting sent back in the correct json format - so that isn't the issue)
handler: function(){
myapp.mainPanel.setActiveItem(myapp.cards.statistics, { type: "slide", direction: "left" });
myapp.stores.statistics.load();
}
Here is my statistics card:
myapp.cards.statistics = new Ext.Panel({
scroll: 'vertical',
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
title: 'Statistics',
items: [{
xtype:"button",
text:"Back",
handler:function(){
myapp.mainPanel.setActiveItem(myapp.cards.home, { type: "slide", direction: "right" });
}
}]}],
items: [
],
store: myapp.stores.statistics,
tpl: new Ext.XTemplate(
'<tpl for=".">',
'<div style="border-top: 1px solid grey;" >',
'<ul>',
'<tpl if="price">',
'<li>{price}:</li>',
'</tpl>',
'</ul>',
'</div>',
'</tpl>')
});
Here is my model which I define much earlier in the code near the beginning of setup:
Ext.regModel('statistics', {
fields: [
{name: 'price', type: 'string'},
]
});
My aim is for the store to have all the stats loaded into it and the panel to show them all via the populated template. Many thanks.
Edit: the store:
myapp.stores.statistics = new Ext.data.Store({
model: "statistics",
url : "statistics.php",
proxy: {
type: "ajax",
reader: {
type: "json"
}
},
});
Edit2: Here is what happens in my statistics.php file:
<?php
echo '[{"price": "333"}]';
?>
