Twitter jQuery typeahead - How to remove the cache

caching, jquery, twitter-typeahead

Solution

Add the `ttl` property to the filter... and set it to 1 not 0.

var countries = new Bloodhound({
    datumTokenizer: function (d) { return Bloodhound.tokenizers.whitespace(d.name); },
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    limit: 10,
    prefetch: {
        ttl: 1,
        url: Url + '/Country/JsonList',
        filter: function (list) {
            return $.map(list, function (country) { return { name: country.Name }; });
        }
    }
});

countries.initialize();

$('.countries.typeahead').typeahead(null, {
    displayKey: 'name',
    source: countries.ttAdapter()
});

Problem

I made a query like this... and first time, it ran the filter... cool, and it worked... But now there are more entries, and it seems to be running off of cache. How do I force it to stop using the cache? ``` var countries = new Bloodhound({ datumTokenizer: function (d) { return Bloodhound.tokenizers.whitespace(d.name); }, queryTokenizer: Bloodhound.tokenizers.whitespace, limit: 10, prefetch: { url: Url + '/Country/JsonList', filter: function (list) { return $.map(list, function (country) { return { name: country.Name }; }); } } }); countries.initialize(); $('.countries.typeahead').typeahead(null, { displayKey: 'name', source: countries.ttAdapter() }); ```
