Filter store records that do not match a value

Question

In ExtJS I would create a filter like this:

store.addFilter({property: 'teamName', value: teamName});

This would filter all records with a teamName of value teamName.

How would I filter it so that it shows all records that DO NOT have this value for this field?

Answer 1

Use filterFn:

A custom filter function which is passed each item in the Ext.util.MixedCollection in turn. Should return true to accept each item or false to reject it.

For example:

store.addFilter({
    filterFn: function(record){
        return record.get('teamName') !== 'teamName';
    }
});
