I found flask-jquery-ajax example where the user selects an item from the vehicle "Make" drop down menu, the vehicle "Model" drop down menu is populated by making an AJAX request for a list of models for the make selected.
I tried to replace the drop-down menus by bootstrap-select and as soon as I include class="selectpicker form-control" in the second drop-down menu it does not get any more populated after the first drop-down has been chosen.
This is the HTML template:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Flask Jquery AJAX Drop Down Menu Example</title>
<link rel="stylesheet" type="text/css" href="//netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" >
<link rel="stylesheet" type="text/css" href=//cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.6.2/css/bootstrap-select.min.css>
<link rel="stylesheet" href="{{ url_for('static', filename='web.css') }}">
<!-- Custom styles for this template -->
<link href="http://getbootstrap.com/examples/non-responsive/non-responsive.css" rel="stylesheet">
</head>
<body>
<h1>Select Vehicle</h1>
<form class="form-horizontal" action="/" method="POST" >
<div class="input-group">
<span class="input-group-addon">Make:</span>
{{ form.make(id="make_select", class="selectpicker form-control") }}
</div>
<div class="input-group">
<span class="input-group-addon">Model:</span>
{{ form.model(id="model_select", class="selectpicker form-control") }}
</div>
<button type="submit">Submit</button>
</form>
{% if chosen_make %}
<h2>You selected:</h2>
<ul>
<li>Make ID: {{ chosen_make }}</li>
<li>Model ID: {{ chosen_model }}</li>
</ul>
{% endif %}
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript" src="//netdna.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.6.2/js/bootstrap-select.min.js"></script>
<script>
$('.selectpicker').selectpicker();
</script>
<script src="/assets/vehicle.js"></script>
</body>
</html>
This is the JavaScript code responsible for populating the drop-down menus:
$("#make_select").change(function() {
var make_id = $(this).find(":selected").val();
var request = $.ajax({
type: 'GET',
url: '/models/' + make_id + '/',
});
request.done(function(data){
var option_list = [["", "--- Select One ---"]].concat(data);
$("#model_select").empty();
for (var i = 0; i < option_list.length; i++) {
$("#model_select").append(
$("<option></option>").attr(
"value", option_list[i][0]).text(option_list[i][1])
);
}
});
});
Why does class="selectpicker form-control" from bootstrap-select cause that the second drop-down menu get not anymore populated?
