How to display JsonReader data in Alert

[bluesapphire]

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

({"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:

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 :

Then click on 'Add Record' link.

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.

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:

,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:

({"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.
