How to display JsonReader data in Alert

Hi!
I am collecting data of a store through JSON Reader. Data received from server is in following format:

Code:

---

({"rights": "No Rights", "total":"2","results":[{"id":"10","c_code":"US","country":"United States"},{"id":"11","c_code":"UK","country":"United Kingdom"}]})

---

I have a button in Top Toolbar of a grid. When I click on this button, I want to display 'rights' value in alert message box. How it would be possible.

Can someone help me in this regards

Thanks in advance

http://localhost/extjs/docs/?class=Ext.data.Store

Read up on methods getAt()

Then read http://localhost/extjs/docs/?class=Ext.data.Record

get()

Eg:

PHP Code:

---

var index = 0;
var record = randomStore.getAt(index);
alert(record.get('rights'));

Hi!
Thanks for guidance. But it is displaying 'Undefined'.

For demo, kindly visit following link :

http://vibersol.com/sitesdemo/rq/ind...admin/country/

Then click on 'Add Record' link.

Still waitng for some pin point solution....

Thanks in advance

I am not going to dig through your js files just to find the right section of code. If you want us to help you, you need to put a little bit of effort into providing the right information.

I get an error: [Break on this error] alert(record.get('rights'));

record is not defined.

Hi!
Following are some codes:

Data Store Code:

Variables 'murl' and 'mind' are path variables and are set.

Code:

---

PnDataStore = new Ext.data.Store({
      id: 'PnDataStore',
      proxy: new Ext.data.HttpProxy({
                                                                       
                url: murl+mind+'admin/country/getData',      // File to connect to
                method: 'POST'
            }),
            baseParams:{task: "LISTING"}, // this parameter asks for listing
      reader: new Ext.data.JsonReader({  // we tell the datastore where to get his data from
        root: 'results',
        totalProperty: 'total',
        id: 'id'
      },[
        {name: 'IDp', type: 'int', mapping: 'id'},
        {name: 'Ccode', type: 'string', mapping: 'c_code'},
        {name: 'Country', type: 'string', mapping: 'country'}
      ]),
      sortInfo:{field: 'IDp', direction: "ASC"}
    });

Following is some of the TBAR part:

Code:

---

,tbar: [{
                  id: 'buttonA'               
        ,text: 'Add Record'
                  ,tooltip: 'Add Record'
        ,iconCls:'add'   
        ,handler: function(){
        if(Ext.getCmp('buttonA').disabled)
          {       
                var index = 0;
                var record = PnDataStore.getAt(index);
                alert(record.get('rights'));
        }
        else{
                var index = 0;
                var record = PnDataStore.getAt(index);
                alert(record.get('rights'));
              }       
    }
                       
}

.......................TBAR continues................................

Following is JSON output:

Code:

---

({"rights": "No Rights", "total":"5","results":[{"id":"1","c_code":"UK","country":"United Kingdom"},

{"id":"2","c_code":"US","country":"United States"},{"id":"3","c_code":"FR","country":"France"},{"id"

:"4","c_code":"CN","country":"China"},{"id":"5","c_code":"JP","country":"Japan"}]})

Hope some one will guide me in this regards

Thanks in advance

I see no point at which the var 'record' is defined.
