Q:

typeahead.js. How do I capture the suggestions list?

I am using typeahead.js. I see no event handler that would let me capture the subset of my dataset suggested by a given query. Is there no way to get the actual subset of rows from my dataset?

A:

You could use the typeahead:rendered event. It passes all shown items as objects in the arguments array. The event is fired immediately after the list of suggestions is shown ...
.on('typeahead:rendered', function() { 
    var array = [], i = 1;
    for (i; i<arguments.length; i++) {
       array.push(arguments[i].value) 
    }
    console.log(array);
});

would console out ["Alaska", "Arkansas", "Illinois", "Kansas", "Louisiana"] if the suggested items in the dropdown is Alaska, Arkansas, Illinois, Kansas, Louisiana ...
