Bootstrap 4 Typeahead

Question

I'm using jQuery Bootstrap Typeahead. I get data from my file but typeahead dropdown is not populate/shown.

Here is my JS:

(function() {
    "use strict";

    var $input = $('.typeahead');

    $('.typeahead').typeahead({
        source: function (query, process) {
            return $.getJSON(
                'url-to-file.php',
                { query: query },
                function (data) {
                    console.log(data)
                    return process(data);
                })
        }
    });

})();

console.log() returns a (correct) JSON array:

[ "item1", "item2", ... ]

But I don't know what to do after. Thanks for helping

Solution

The data source should be...

[{name:"item1","id":"1"},{name:"item2","id":"2"},etc..]

And then use data-provide on an input like this...

   <div class="input-group">
       <input type="text" data-provide="typeahead" class="form-control typeahead border-primary" name="query" id="query" placeholder="search..." autocomplete="off">
   </div>

Edit: You can also use a simple string array: https://www.codeply.com/go/knBpcbhlFE

Actually your example works fine, but it loads the json data directly. My goal is that each time the user press key, a query is done in my database searching for the query and "then" return the json data. I'm ok with that but after I don't know how to inject/populate the dropdown list.

That would basically work the same as explained here: stackoverflow.com/questions/18710325/…

booth codeply examples doesnt work for me in FireFox (65.0.5) but works in Chrome

The links work for me, and besides the relevant code is in the answer too. Why did you downvote this? @SergeyRomanov

Because all links ave me 404 at that time like example is not there anymore. Now all works fine. I wanted to upvote but it does not let me until a post is edited. Sorry. Most probably that was so a problem with a codeply. Because 404 error was not a browser but their. Styles as codeply not found repo.
