AJAX不与引导，选择工作 [英] AJax does not work with bootstrap-select
问题描述
我发现烧瓶jQuery的Ajax的例子中，用户选择一个项目从车辆制作下拉菜单中，车辆模式下拉菜单，是通过一个AJAX请求的模型选择做一个清单填充。
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.
我试图以取代下拉菜单中的引导选的，一旦我有类=selectpicker形式控制的在第二个下拉菜单也没有得到任何填充更多的第一个下拉已被选定之后。
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.
这是HTML模板：
<!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" >

<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>
这是JavaScript code 负责填充下拉菜单：
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])
);
}
});
});
为什么从的引导选的原因是，第二个下拉菜单中得到再也没有填充？
Why does class="selectpicker form-control" from bootstrap-select cause that the second drop-down menu get not anymore populated?
推荐答案
AJAX完成后，您需要重新加载插件：
After AJAX is done, you need to reload the plugin:
$('#model_select').selectpicker('refresh');
