Finding records of similar type

[harman]

HI,

I have an ExtJS 4.0.7 Store that is populated with json to show in a grid.
One field in every record defines its group.
How do i count out the records belonging to same group and name of different groups.
I do not want to use grouping feature as it causes various sorting issues.

Thanks in advance

You can filter the store to count unique values ..

Just update code to add counter.


Ext.create('Ext.Button', {
text: 'Filter Me',
renderTo: Ext.getBody(),
handler: function() {
var uniqueValue = '';
store.filter( // filter unique names
{
filterFn: function(item) {
var name = item.get('name');
if (uniqueValue !== name) {
uniqueValue = name;
return true;
} return false;
}
});
}
});
