Ext.data.JsonPStore example

**ci11111** · 19 Feb 2012, 2:47 AM

Hi
I would like to load the equivalent images of http://dev.sencha.com/deploy/touch-c...examples/Line/ but from a local file

so I need to replace

Code:

window.store1 = new Ext.data.JsonStore({
    fields: ['name', 'iphone', 'ipad'],
    data: data
});

with something like

Code:

window.store2 = new Ext.data.JsonPStore({
    // proxy configs
    url: 'http://dev.sencha.com/deploy/touch-charts-1.0.0/examples/resources/shared/img/',
    // reader configs
    //root: 'images',
    fields: ['name', 'iphone', 'ipad'],
    data: data
});

I didn't got it working the JSONPStore
do you have any idea?

What was the response? Is it valid for JsonP which requires JSON be wrapped int he callback function?

**ci11111** · 20 Feb 2012, 1:44 AM

for both methods, the images are not loaded, I have an http no-content error since it tried to load from my local computer
(iphone.png /home/ca/resources/shared/img GET (failed) undefined touch-charts.js:1 Script 13B 0B 16ms 0.0 days)
I have no images there but want to fetch the remote ones (http://dev.sencha.com/deploy/touch-charts-1.0.0/examples/resources/shared/img/iphone.png ...) with jsonp if the first method fails with the cross domain thing, or to have a working example of jsonpstore

thanks for the help mitchell

I have no idea how to set up Jsonpstore
If you, please, have time and correct the example above

**mitchellsimoens** · 20 Feb 2012, 6:25 AM

It's not really the store, it's the response.

**ci11111** · 20 Feb 2012, 6:39 AM

If you try copy pasting the above code in #3
you will see it works exactly like sencha example, except the pictures that doesn't load, if you don't have created locally the folder resources/.../img and put pictures
I asked if it's possible and how to set up a Jsonpstore to fetch remote pictures to be displayed in the charts
thanks
