How to store data using ajax request into local storage?

[Dragonrider]

I am a new user to sencha.

Right now I am showing data into list using ajax request but I want to store that data from ajax request to localstorage so, everytime I do not have to fetch particular data from the file.

Data is stored into json file.

Any help would be appreciated.

Thanks

You will need two data stores... one that will get the data via ajax like you are doing and another to do the saving to localstorage. You would then have to use events in the live store to sync with the offline store.

I tried by creating two stores one is for ajax request and another is for localstorage.

I am using google chrome javascript console for cheking localstorage.

It shows me localstorage with null values.

Ext.Ajax.request({
url: 'result.json',
success: function(result) {
var jsonData = Ext.util.JSON.decode(result.responseText);
test.add(jsonData);
});

var test = new Ext.data.Store({
storeId: 'Test',
model: "testData",

proxy:{
type: 'localstorage',
id: 'test-storage'
}
});

Any solutions would be very grateful to me

Hi...
Am new to sencha and just started working with sencha architect 2, I went through the docs about loading data using store, model, ajax and local storage but yet am not able to get it exactly..My question may look pretty simple but pls bear it and answer step by step:
1. I designed a simple login page like(Views):

- Mytabpanel
-Login // tab1
-MyContainer2
-MyNavigationview1
-Myformpanel1
-Mytextfield1 // Username
-Mypasswordfield1 //Password
-mybutton1
-tap onmybuttontap1 // Login button
-abc label // should display error if both textbox left empty

-Menu // tab2
-Mynavigationview
-Mycontainer
-Mypanel
-Mylist
-item tpl // not able to edit the default list then saw example giving local storage using model,store and ajax request but am not clear about it...


-Map //tab3
-Mynavigationview
-mycontainer
-MyMap2 // which displays google maps API is required...


My needs:


1. Navigation view doesn't provide default back button
2. When first list is pressed, it should navigate to next page comprising of another three or five list //// tab2
3. When username and password field left empty and clicked login tap should display an error in label
4. Finally how to retrieve data from sql server 2005 using ajax request then local storage using store and model...
Please bear it and try to answer me, i have also attached zip if possible try to modify it..
Thanks in advance!!!
