Hi,
this is my code.
I need to read records variable when i use dblclick event
...
success: function (response) {
if (response.responseText!='') {
var records = Ext.decode( response.responseText );
var count = records.length;
var i=0;
for(i=0;i<count;i++) {
var obj = [
{
id: 'portlet_'+records[i].id,
itemId: 'portlet_'+records[i].id,
title: records[i].title,
items: Ext.create(records[i].portletClass),
height:200,
listeners: {
render: function(c){
c.el.on('dblclick', function(){
if (typeof currOspite!="undefined"){
//here i need to read records variable
creaWin(records[i].id,records[i].title);
}
});
}}
}
];
items_to_load.push(obj);
}

}
}
});
...

Have a look at the data and items objects

var jsonData = Ext.util.JSON.decode(xhr.responseText);
jsonData.data
jsonData.data.items

Use firebug to see your data coming back from your server.

Sorry but I'dont' understand how i can read the variable "records" declared above..
..
//here i need to read records variable
creaWin(records[i].id,records[i].title);

Assuming you have a table with abbr,name populated with states

// make ajax call

handler: function() {
	Ext.Ajax.request({
		method: 'POST',
		url: 'list.php',
		scope: this,
		// so we can access ref of field below
		success: function(xhr) {
			jsonData = Ext.JSON.decode(xhr.responseText);
			var records = jsonData.data; // data return from server; see below
			console.log(records.length); //50
			console.log(records[0].abbr); // AL
			console.log(records[0].name); // Alabama
		}
	});
}

return data from server

listData('states');
    
function listData($table) 
{
    $sql = 'SELECT * FROM '.$table;
    
    $result = mysql_query($sql);
    
    while($rec = mysql_fetch_array($result, MYSQL_ASSOC)){
        $arr[] = $rec;
    };

    $rows = 50; // hard coded for this example
    $data = json_encode($arr);  //encode the data in json format
      
    echo $cb . '({"total":"' . $rows . '","data":' . $data . '})';
}

I resolved... but I'm not sure it's the correct solution.

render: function(c){
c.el.on('dblclick', function(){
if (typeof currOspite!="undefined"){
creaWin(records[0].id,records[0].title);
}
});
}}
