jquery - Twitter jQuery typeahead - 如何删除缓存

Question

我做了一个这样的查询...第一次，它运行了过滤器...酷，并且它起作用了...

但是现在有更多的条目，并且它似乎耗尽了缓存。如何强制它停止使用缓存？

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()
});

Answer 1

我认为这比接受的答案更好:

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 }; });
        },
        cache: false //NEW!
    }
});

countries.initialize();

$('.countries.typeahead').typeahead(null, {
    displayKey: 'name',
    source: countries.ttAdapter() //NOTE: .ttAdapter() is deprecated and will be removed in V1
});
