How to fill the second field on the basis of the input from first field LIVE

I have two input fields 1. Name , 2. Telephone. All i want is (1. When I start typing name it must search from database for autocomplete Now when the Name is selected from search query i want Telephone input to be filled automatically on the basis on Name selected. Currently I'm using typeahead.js to autocomplete the Name search.

        }

        .content {
            width: 80%;
            margin: 0 auto;
            margin-top: 50px;
        }

        .tt-hint,

    <script>
        $(document).ready(function() {

            $('input.Name').typeahead({
                name: 'Name',
                remote: 'city.php?query=%QUERY'

            });

        })
    </script>




</head>

<body>
    <div class="content">

        <form>
            <h1>Try it yourself</h1>
            <input type="text" name="Name" size="30" class="Name" placeholder="Please Enter Name or ZIP code"> </input>

            <input type="text" name="Telephone" size="30" class="Telephone" placeholder="Telephone"> </input>

        </form>
    </div>
</body>

</html>

My PHP Code : //Not putting database connection part (Obviously i have connected it)

<?php 
if (isset($_REQUEST['query'])) {
    $query = $_REQUEST['query'];
    $sql = mysqli_query ($conn,"SELECT Name,Telephone FROM customerdetails WHERE Name LIKE '%{$query}%'");
    $array = array();
    while ($row = mysqli_fetch_array($sql)) {
        $shu[] = array (
            'label' => $row['Name'],
            'value' => $row['Name'],

        );
    }

    echo json_encode ($shu);
}

?>
Solution

    1. The script city.php have to return values for names and telephone number. In your example you have twice $row['Name'].

    2. You have to separate the values that the names are used for the original typeahead search (try template like here) and the telephone number is used when a name is selected. Not used to typeahead but found this solution which looks solid to me to achive what you want.

      $('input.Name').typeahead({
    name: 'Name',
    remote: 'city.php?query=%QUERY',
    updater: function(item) {
        // try to get telephone number out of "item" and set it to the telephone number field
        return item;
    }
});

    What version of typeahead are you using? https://github.com/twitter/typeahead.js? Maybe you need to include the bloodhound suggestion module...
