清空时触发Typeahead.js事件

Question

I have Typahead.js plagind and want to set data-id attribute to '' when input field is empty. Now I'm using it to set data-id when specific suggestion is selected, but when it is empty can't catch an event.

typeaheadFields.bind('typeahead:select', function (ev, suggestion) {
    $(this).parent().find('.attribute-slider-category-id').attr('data-id', suggestion.id);
});

Answer 1

Fixed with this:

typeaheadFields.keyup(function () {
            if ($(this).val() == '') {
                $(this).parent().find('.attribute-slider-category-id').attr('data-id', '');
            }
        });
