I have implemented my sencha architect project with a possibility to do a photo (with phonegap). After taking a photo, I need to see the photo directly into another container with other information (the picture will be smaller than the original...and there will be written above and below).
How do I open the new container and display the image in a smaller size?
please help me, I don't understand how can I manage the photo
Now I use this code but if you have something better....
var me = this;
Ext.device.Camera.capture({
success: function(image) {
me.add({
xtype:'image', // Commento
src: image
});
},
source: 'camera',
cameraDirection: navigator.camera.Direction.FRONT,
destination: 'file'bu
});
thank you
Carlo
Sencha documentation got an example for it. See http://docs.sencha.com/touch/2.3.1/#!/api/Ext.device.Camera
Ext.device.Camera.capture({
success: function(image) {
imageView.setSrc(image);
},
quality: 75,
width: 200,
height: 200,
destination: 'data'
});
You can also use
destination: 'url'
in that case the image argument of the callback function will be a file URL what you can use in a container template as the source of the html image.

I am new to Ext Js 4.1, I have 5000 child nodes and need to load only 50 nodes on load,after scrolling down have to load another 50 nodes and continues. I am trying from past 2 days with different scenarios, but I didn't find anything related, can anu one please help me how to do, if possible with sample code.
Thanks in Advance
The only way to do this with a server that gives you your's 5000 child nodes is to use a buffered store.
Using a buffered store you can set your page dimensions and scrolling down changing the page you will be able to load your datas 50 by 50 records.
check all you need here http://docs.sencha.com/extjs/5.1/5.1.2-apidocs/#!/api/Ext.data.BufferedStore
buffered store disponible also on ext 4.1
also some examples on sencha examples
you can watch this
http://dev.sencha.com/deploy/ext-4.0.0/examples/grid/infinite-scroll.html
Finally i find the solution that we need to use 'bufferedrenderer' Plugin.Infinite grid uses a buffered store, and is not supported for trees.
Here is the sample code
Ext.onReady(function () {
var store = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'http://localhost/codig/index.php/user/jsonusers',
extraParams:limitValue
}
});
store.reload();
var treePanel = Ext.create('Ext.tree.Panel', {
id:'mytree',
title: 'Infinite nodes tree',
width: 200,
height: 400,
store: store,
rootVisible: false,
plugins: {
ptype: 'bufferedrenderer'
},
renderTo: Ext.getBody()
});
});
i am working on Extjs4 file upload control. i have view with file upload control as-
Ext.define('Balaee.view.kp.dnycontent.Content',
{
extend:'Ext.form.Panel',
requires:[
'Balaee.view.kp.dnycontent.ContentView'
],
id:'ContentId',
alias:'widget.Content',
enctype : 'multipart/form-data',
title:'This day in a history',
items:[
{
xtype: 'fileuploadfield',
hideLabel: true,
emptyText: 'Select a file to upload...',
//inputType: 'file',
id: 'upfile',
width: 220
}],
buttons: [{
xtype : 'button',
fieldlabel:'upload',
action:'upload',
name:'upload',
text: 'Upload',
formBind:'true'
}]
});
And corresponding action in controller is-
getUpload : function() {
var file10 = Ext.getCmp('ContentId').getEl().down('input[type=file]').dom.files[0];
var reader = new FileReader();
reader.onload = function(oFREvent) {
fileobj=oFREvent.target.result;
console.log(oFREvent.target.result);
};
}
});
So above controller's function is retriving uploaded file and displaying it in encoded format inside reader's onload function. i.e. "console.log(oFREvent.target.result);" line is displaying uploaded file's data in encoded format in console. I need to send this file to server side. So i am passing above fileobj as parameter to store as-
var storeObj=this.getStore('kp.DnycontentStore');
storeObj.load({
params:{
data:fileobj
},
callback: function(records,operation,success){
console.log("send");
},
scope:this
})
But its showing fileobj as undefined outside reader.onload function. So how to send this file along with its contents to server side? Is there any other way to get uploaded file in controller and send it to server. Please can someone guide me.
I dont know how to handle fileuplaod on php side, but the return response from the server needs to be text/html encoded
See the docs on this:
http://docs.sencha.com/ext-js/4-1/#!/api/Ext.form.Basic-method-hasUpload
also example PHP fileupload script:
http://www.w3schools.com/php/php_file_upload.asp
I want to show the data from the following API in List :
http://customer.appxtream.com/astro.apps.cms/jsonFeed.action/?service=astroSportsDataService&action=grabJsonText&mimeType=application/json&p1=HighlightNewsList&p2=EURO2012
when I get the data, the Network of Chrome shows me that all elements have been retrieved but List shows only the data from the last item in the API here is my code:
View
Ext.define('astro.view.HighliteNews', {
extend: 'Ext.DataView',
xtype: 'highliteNews',
config:{
title:'xren',
store: 'highliteNewsStoreId',
itemtap: true,
scrollable:'horizontal',
inline:{
wrap:false
},
itemTpl:[
'<div><img src="{imageLink}"/> </div>',
],
},
});
Store
Ext.define('astro.store.HighliteNewsStore',{
extend: 'Ext.data.Store',
xtype:'highliteNewsStore',
config:{
model: 'astro.model.HighliteNewsModel',
autoLoad: true,
storeId: 'highliteNewsStoreId',
proxy:{
type:'ajax',
url :'http://customer.appxtream.com/astro.apps.cms/jsonFeed.action',
extraParams:{
service:'astroSportsDataService',
action:'grabJsonText',
p1:'HighlightNewsList',
p2:'EURO2012',
mimeType:'application/json'
},
reader:{
type:'json',
rootProperty:'cmsHighlightNewsList',
},
},
}
});
Model
Ext.define('astro.model.HighliteNewsModel',{
extend: 'Ext.data.Model',
config:{
fields: ['imageLink'],
}
});
So the network shows that 3 images are sent from API but the List shows ONLY LAST IMAGE.
Please help
I solved the problem guys :) , there is an conflict between Sencha and JsonP, so if you assign a idproperty to your Model, the problem will be sloved :
config:{
idProperty: 'HighliteIdProperty',
fields: ['imageLink'],
}
A few things I would suggest :
Add a listener to the load event of the store
This is just to check that all the data is load in your store.
You can do it in different ways :
In a controller
store.on({
load:function(){
console.log(store.getCount());
}
});
or directly in the store config with the listeners attribute
listeners:{
load:function(store){
console.log(store.getCount());
}
}
Check the DOM
In the Web Inspector / Firebug, check if your items are there or only the last one.
I think you could also try this command in the console :
Ext.DomQuery.select('div[class=x-dataview-item]').length
It will return the number of items in your dataview.
Set a width and height to your image
I also had the same problem with a dynamically loaded dataview. All the picture were there in the DOM but too small to be seen. So I suggest, you give them a CSS class with a defined width and height.
That's all I can think of for now.
Hope this helps
Thanks Arash for this question and answer. We are facing similar problem and found that we didn't have model defined. Defining the model worked in our case. However, it worked while we retrieved playlist from youtube and now while retrieving the list from google spreadsheet. Hope this helps others who are using google spreadsheet.
adjust the height in the config of view......this might be a problem
I am trying to take a picture using camera in Sencha Touch 2. Here i have one button 'Take a Picture', when i will press it, camera should start. As i am new to this sencha touch 2, i am unable to figure it out, how to do this?
For this i used the below code:
Sencha Fiddle Link
Please help me. I do not want to use Phone gap.
You have to add device folder of Sencha Library in root directory
and add below code in
Ext.require('Ext.device.Camera');
and use this code for capture image using camera
Ext.device.Camera.capture({
success: function(image) {
imageView.setSrc(image);
},
quality: 75,
width: 200,
height: 200,
destination: 'data'
});
If you want to use purely sencha, then you can check this code:
xtype: 'button',
handler: function(button, event) {
Ext.device.Camera.capture({
source: 'camera',
destination: 'data',
success: function(imagedata) {
var img = Ext.getCmp('theimage');
img.setSrc('data:image/jpeg;base64,' +imagedata);
},
failure: function() {
Ext.Msg.alert('Error', 'There was an error when acquiring the picture.');
},
scope: this
});
But if you want to use phonegap camera features, may be you have to change the code. As sencha is giving the default feature to handle the camera, i wish not to go with phonegap. Hope it will help..
iam new sencha touch.
Iam doing one project , in that project i need to convert the images to base64 string, iam uploading the image, and iam getting fulll path of image, but iam unable to convert image to base64 string.
plz help me in this issue.
make sure that iam asking in sencha touch
How do you access the files? Where the images are coming from? If they are from the camera or the photo gallery then Phonegap is the best way to get them. Base64 encoding is solved by PG in that case. If you are trying to solve it in pure js then you need to do some more work on it. Sencha doesn't provide functions for base64 encoding. So the best bet if you add some function to your project. There are lots of resources on the web how to do base64 encoding in javascript. E.g. see the discussion here Base64 encoding and decoding in client-side Javascript
The following code snippet helps you for uploading image and get base64 data uri
In your view you should have the following filefield component of sencha touch
Ext.define('MyApp.view.Main', {
extend: 'Ext.form.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.Video'
],
config: {
tabBarPosition: 'bottom',
items: [
{
xtype: 'filefield',
id: 'idfilefieldSample',
name: 'filefieldSample',
accept: 'image'
},
]
}
});
and your controller look like this:
Ext.define('MyApp.controller.MainController', {
extend: 'Ext.app.Controller',
config:{
control:{
'filefield[name=filefieldSample]': {
change: 'onChangefilefield',
},
}
},
onChangefilefield: function(filefield, newData, oldData, eOpts)
{
var filesSelected = Ext.getCmp('idfilefieldSample').getComponent().input.dom.files;
if (filesSelected.length > 0)
{
var fileToLoad = filesSelected[0];
var fileReader = new FileReader();
fileReader.onload = function(fileLoadedEvent)
{
var srcData = fileLoadedEvent.target.result;
console.log(srcData);
}
fileReader.readAsDataURL(fileToLoad);
}
},
});
