Data not coming from jsonp

[sirwanimayur]

Not able to see any data in this list
Any guess why it is not working

Ext.define("StockWatch.view.MarketList", {    extend: "Ext.dataview.List",
	requires: "Ext.plugin.PullRefresh",
    xtype: "marketlist",
    config: {
        loadingText: "Loading Markets...",
		layout: 'fit',
		plugins: [
            {
                xclass: 'Ext.plugin.PullRefresh',
            }
		],
		store: {
			fields : ['CompanyCode','LastTradedPrice'],
            proxy : {
				type:'jsonp',
                url:'http://money.rediff.com/money1/current_status_new.php?companylist=17023928%7C17023929&id=1354690151&Rand=0.6305125835351646',
				callbackKey: 'callbackJsonp',
                reader: {
					type: 'json',
					rootProperty: ''
                }
            },
            autoLoad:true,
        },
        emptyText: '</pre><div>No markets found.</div><pre>',
        onItemDisclosure: false,
        itemTpl: '</pre><div>{CompanyCode}</div><div>{LastTradedPrice}</div><pre>',
    }
});

At first glance I see you have some trailing commas sprinkled about in your code. Also, have you reviewed your error console when you run your code? What does that report? Have you verified that your service is returning your callback as expected? Check this stuff out then post more details/information if necessary.

console has no error, just a warning, the server returned ot as a script but changing it to text/html or some kind of this...

i'm getting this response when i hit url on browser

[{"CompanyCode":"17023928","LastTradedPrice":"19,476.00","Volume":"0","PercentageDiff":"0.57","FiftyTwoWeekHigh":"19,612.18","FiftyTwoWeekLow":"15,135.86","LastTradedTime":"19 Dec,16:00:21","ChangePercent":"0.57","Change":"111.25","MarketCap":"0.00","High":"19,516.02","Low":"19,419.76","PrevClose":"19,364.75","OpenInterest":"","MarketLot":"","ChangeInOpenInterest":"","Symbol":null},{"CompanyCode":"17023929","LastTradedPrice":"5,929.60","Volume":"0","PercentageDiff":"0.56","FiftyTwoWeekHigh":"5,965.15","FiftyTwoWeekLow":"4,588.05","LastTradedTime":"19 Dec,16:27:55","ChangePercent":"0.56","Change":"32.80","MarketCap":"0.00","High":"5,939.40","Low":"5,910.80","PrevClose":"5,896.80","OpenInterest":"","MarketLot":"","ChangeInOpenInterest":"","Symbol":""}]

I dnot know how to check if server is returning a callback thing that u r saying

[bricemason]

Your json encoded data is not wrapped in a callback function. See the docs for the jsonp proxy here:

http://docs.sencha.com/touch/2-1/#!/...ta.proxy.JsonP

The second code figure in those docs will show you the difference in your data.

So that means I wont be able to show this data on list??
any way on how to achieve this?

[bricemason]

You can certainly show that data. You just need to fix what's returned from your jsonp service. The snippet I was referring to in the docs was this:

someCallback({
    users: [
        {
            id: 1,
            name: "Ed Spencer",
            email: "ed@sencha.com"
        }
    ]
});

This snippet demonstrates the data being wrapped in a callback.

Your proxy has a custom callback key of callbackJsonp. This is telling your service to use the callback name that's defined in the querystring parameter of callbackJsonp. If you inspect the url that's being requested with your proxy you'll see that.

I recommend reading the docs for JsonP proxy very carefully so you can get the concept down.

That is some external API I'm using, I cant edit that

[bricemason]

Then in that case I'd recommend just creating your own server-side facade that interacts with that service. Then you can just use an ajax proxy.

Ohk
Any idea if I can read this data as string and then parse it to json and display it on the client side itself?

[bricemason]

No real need to parse it unless you want to change it in any way inside your facade. But if you just want the data itself, your facade would basically:

1. Perform GET request of http://money.rediff.com/money1/current_status_new.php?companylist=17023928|17023929&id=1354690151&Rand=0.6305125835351646
2. Print the data that's returned from that request

Then you'd use an ajax proxy (http://docs.sencha.com/touch/2-1/#!/...ata.proxy.Ajax) with your json reader just like you had before.
